Is the 944 reliable?

I see many people asking is the 944 reliable and the answer is yes and no. Mine had a few issues when I got it but got them sorted and daily drove the car for 6 years, mostly incident free, then had some more serious issues(hard to diagnose) but now its super reliable. The engines on these cars are incredibly reliable, so most issues come down to a few other causes, mostly electrical, but in this article I’ll address those issues, and what can be done to get rid of many potential reliability issues for many years. It is just a general guide based on my experience and not a technical guide for diagnosis of problems.

DME, the sensors, and relay

Speed and Reference Sensors

944’s have an engine management system made by Bosch called a DME(Digital Motronic Electronics). It is a fuel injected system the uses 2 sensors{on most models later that changed to one sensor) known as the speed and reference sensors. These tell the engine management system(DME) what the pistons are doing and when to fire the fuel in and when to to trigger the spark plugs, etc. Unfortunately when people get a “no start” situation, often the first thing people suggest, is replace these 2 sensors. That’s not bad advice, as it is a possible cause, but replacing parts that aren’t faulty, not only gets expensive but won’t fix the issue, unless you are lucky and that it was actually the cause. As the wiring harness is very old now, often its not the sensors but the wiring back to DME, from the connectors at back of engine, that then goes to the DME box itself. You can buy replacement harnesses from Lindsey Racing and I highly recommend this. Personally I have replaced all the engine harnesses, as it gets rid of all potential electrical gremlins related to old wiring adding massive reliability

The testing procedure for sensors is at a site all 944 owners should have bookmarked, called Clarks garage click here to sensor test page. This site has so much information and apart from some advice written over 25 years ago, that’s now a little out of date, the site is invaluable. One of the things it suggests is glueing an 0.8mm washer to an old sensor, to set depth of sensor. Do not do this because if that washer comes off, you are in a world of pain, as it falls into a place that is expensive to open up and also we now have a cheap tool to do the job Click here to buy tool. The reason you need to set depth is, its critical the sensors are the right distance to flywheel, to get an accurate trigger signal for DME. If you can get sensors out without removing bracket, then you don’t need to set depth again. Unfortunately more times than not, the bracket needs to be removed to get old sensors out.

There is another alternative to fitting all new harnesses from Lindsey racing, which is what I did, and requires fitting them into factory connector at DME, which can be a bit daunting(but isn’t that hard, as long as you are patient and methodical), is to buy a complete harness. Recently a company called Kroon wiring decided to support the 944 community and is making complete replacement engine harness. This isn’t a cheap option but the harness is probably better built than when car left the factory, so will ensure reliability for many many years to come and just plugs in to DME and avoids the fiddly work needed with the Lindsey racing replacements to be fitted in factory DME connector, although obviously both still need to be hooked up to everything in engine bay. Its also possible for them to wire in custom integration for other non-original sensors, like to monitor intake temps or something, directly into the harness.

DME relay

The DME relay is used by the DME and ignition, to turn on fuel pump. For many years people often carried 2 or 3 in glovebox, as they are an old analogue relay, that’s prone to failure at the most random and inconvenient times. Quality of replacement vary and I had a lot of problems with ones I had, so genuine Porsche are the best but we now have an option that should mean the end of being stranded by these. It a solid state relay made by Focus9 technology and I was a beta tester for them and been using one since 2016 and highly recommend them. They have 2 versions, standard which I use and pump prime that activates the fuel pump for 3 seconds before starting, to make starting easier. If buying today I’d get pump prime but have no issues starting with standard unit. Some people re-solder broken relays and get them working again but as they are only putting off the inevitable, I think the solid state are way to go for reliability.

DME(engine control unit)

With my car the DME box(ECU) had a random problem when I first got it 10 years ago, and the guys I sent it too couldn’t work it out exactly what it was, even though it tested faulty, so sold me a rebuilt unit. Now we have more options and I wouldn’t suggest getting the DME rebuilt as its very old now, and there are several better options. Even if fixed, the age means it may cause further problems later, due to age and construction, and technology available at the time car was built.

Which option is best depends on a couple of factors. If you own a normally aspirated(NA) car(a non turbo), or a turbo, whether you don’t plan to modify it or not. One option is the Focus 9 technology solid state DME(ECU) replacement. This is made with latest technology and will outlast most of us. These guys reverse engineered the DME and then made a new version that is built with 40 years newer technology. It does require a core exchange. They also have a version for “spec” racing version that is a control class of racing, so cannot be modified

The more advanced options, for those who either want to do modifications at some point or want to improve basic performance, like throttle response, is to go a tune-able set up. These allow the fuelling, timing, and other settings to be changed and are essential on turbo models, if you want to improve performance by upgrading turbos, injectors, etc, but they will still benefit an NA(whether the expense is justified on NA’s is another matter). They also allow changes to be made at any time and can be retuned to accommodate the new changes

VEMS

VEMS(versatile engine management system) is the stand alone system I personally use. My factory Air Flow Meter(AFM) had begun to play up and couldn’t be fixed. I could have bought a refurbished AFM, but as they are no longer made, so how long it would last is unknown, and they are very expensive refurbished. Buying a used one, then it may not even work at all, a gamble I wasn’t willing to take. I decided on VEMS because although, like all stand alone systems, a dyno-tuner can tune the car, it also has an autotune function, that basically self calibrates the system enough for it to be very drivable without the expense of dyno tuning time. It allows removal of the factory AFM, which not only improves air flow into engine but adds reliability, as it uses an Air temp sensor and wideband oxygen sensor for precise tuning. Far more precise than the original DME. It’s also a plug and play system that plugs directly into factory harness. It does require IAT(internal air temp) sensor and a wideband O2 sensor to be fitted, but that’s not complicated or expensive, and any decent mechanic can get that done easily or can be done yourself if you can weld the bungs required for sensors in. I added wasted spark ignition too, as it takes distributor out of equation, that needs parts that need to be maintained.

MAXXECU, MEGASQUIRT, Motorsport Engineering and other options

These ECU’s are known as stand alone units, as they are a complete management systems. Some like Motorsport engineering are packaged into a plug n play like VEMS is, and others require a bit more work to install. Some come with a raw harness that needs to be installed, which is a lot of work, some with base tunes to get you going, and some that will not only require a wiring loom to be built from scratch but require dyno tuning before car will run and drive. They do offer virtually unlimited performance upgrades, with monitoring at the highest level of anything possible and you can add features like boost by gear, traction control, anti-lag and more, easily.

The thing about stand alones is, without the community support, you are on your own and either need to know how to tune, wire and set up yourself, or are at the mercy of your tuner and mechanic. That’s ok too, but if relying on someone else to install and set up, it is very expensive. Megasquirt has a huge amount of community support on rennlist forum, Maxxecu(new option for turbos and in early days) on the facebook group “Premier 944 turbo and 968 turbo group” and Augtronic and Motorsport Engineering by tuners in UK and Europe, as does VEMS, so making a decision between them, can be important just based on where you live, or based on your tuning skills and fabrication and wiring skills.

Vacuum Leaks

These cars have vacuum lines running all over the place in the engine bay and even in the car for the heater control. The original lines often have leaks that can cause all sorts of problems. These should all be replaced and you can get kits or just buy silicone hose yourself. Although you would think that replacing them would solve any vacuum issues, there is one other place a leak can cause an issue, and that’s the throttle body. The throttle body is meant to be sealed and a leak can mean the DME is getting the wrong reading of air going into engine, so car will have incorrect air to fuel ratio, and can run poorly

Fuel Lines

More than just a reliability item, these are a safety item too, as having the car burn down does effect the drive-ability a bit. The original fuel lines can split and fuel is under tremendous pressure so if they go, its right over a hot exhaust. You can buy braided lines but I prefer aeroquip fuel lines, as it means they are easy to visually examine as they age. The lines at rear are less of an issue regarding an instant fire, as not over hot exhaust but also a good idea to inspect regularly and replace if needed.

Grounds

The importance of good grounds can’t be over stated. Luckily it costs nothing to clean and reattach them. On some cars ground straps from battery may need to be replaced. For the engine, the ground point is just near the speed and reference sensors at the back of engine between bell housing and firewall. Cleaning is just a matter of removing them and cleaning area of grime and cleaning the terminals with light sanding. There are I think 7 ground points and its a great idea to clean them all. It varies from models being LHD and RHD but there are diagrams online that show you locations. As everything from DME, sensors, and gauges, require a good ground signal, it’s definitely worth doing and free

Is my car reliable?

I bought my 86 turbo in 2010 (today, so its our anniversery šŸ™‚ As mentioned above I had a problem with DME when I first got it but had that sorted a few weeks later. It went great and I was driving it everyday but occasionally I’d have the dreaded random no start. it was very rare but also very frustrating. I could always roll start it, so always parked with that in mind and often had work colleagues who would get roped into helping. I actually put up with this for about 6 months while searching online for possible solutions. I read that you could sometimes jiggle wires at back of engine where speed and reference sensors connect to factory loom and car may start. Sure enough it worked and I realised it was the factory wiring back to DME that was the problem. I ordered the Lindsey racing replacement harness and as I am down under and shipping here is so expensive, I thought I may as well get some other things at same time. Luckily one of those was the fuel injector harness. Now when the stuff arrived, I kept driving for a bit using jiggle method if the car wouldn’t start, but when I finally got around to fitting the harness, I thought it made sense to look at fuel injector harness too. Although I hadn’t had an issue with it, when I touched the connector at the injector, the factory harness broke off in my hand. I then fitted the new fuel injector harness. I realised I’d dodged a bullet, as it was just a matter of time till that harness would have broken and left me stranded and scratching my head to the cause. This is why, if you want a reliable car, I think the harnesses are so important.

When I started to have the issues, that the worn out Air Flow Meter(AFM) caused, I tried replacing many parts to fix it, not know what the cause was. Often I knew it was unlikely to be the solution but figured at least the parts would be good for many years and I might get lucky and also some things I was planning on doing anyway. I was also between mechanics and so sort of stuck on my own trying to work it out. I replaced the fuel pump to a HV unit from Lindsey Racing, fuel filter, distributor, cap, leads, fuel rail(CEP), rebuilt injectors, Tial F38 dual port waste gate and Turbosmart electronic boost controller, AFR gauge(Zeitronix ZT2) with EGT, and probably a few other things I’m forgetting. I also had to fit most of these things myself, so learned a lot doing it and am far more confident tackling mechanical tasks these days

Once it was figured out it was AFM, I weighed up options and decided on stand alone. Initially I bought an M tune set up but couldn’t get car to run. This wasted a lot of time and money but I eventually gave up and bought VEMS. A few weeks later it arrived and once fitted to the car, she started first time and I’ve never looked back

So yes my car is very reliable and starts first time, every time, and I wouldn’t hesitate to take it on a long trip. Yes its had some issues as you would expect for a car of its age, but the majority of the time(90+%) I have owned it, its been driven daily and reliable. I have done the things to it, I think are needed, to make it reliable and will make any 944 very reliable. If you also want a reliable 944, then it takes a little work but if you address the primary causes of problems, outlined above, then these cars are very reliable and very few other cars have the engineering behind them mechanically, to do the sort of mileage these cars do consistently, combined with handling, style, and looks that are hard to beat.

Samsung Galaxy Note 10+

Samsung Galaxy Note 10+

galaxy_note_10_leak_ishan_agarwal_combo.0

Well, after many happy years using only Sony phones, I dropped my beloved Sony and the touch screen stopped working, rendering it a paper weight.Ā  Unfortunately my phone company or any other phone company here in Australia, no longer stocks Sony or I would have got the new Sony X1. I wasn’t in a position to buy the Sony X1 outright, so a little reluctantly, I decided to go with the Samsung Galaxy note 10+. I have had the phone for a few weeks now, and I must say I am impressed. It is their flagship phone and it shows.

What I Like

What I like, and there is a lot to like in my opinion. Once you have navigated all the options it has, and got it set up how you like (which I feel like I might be doing for some time to come) the phone is fantastic. It is no particular order

The S-Pen. Being able to write out quick notes, using normal handwriting on the screen is very cool. Then being able to set a location to that note or a time/date, is fantastic. For someone like me, who comes home from shopping and then realises I forgot the one thing I went there for, it’s perfect. I can write a shopping list and then set the supermarket location, and then next time I pop into the the supermarket, the list pops up. Brilliant.

IĀ  can also write emails or phone numbers in a note, with my handwriting, and then add them to contacts or send an email or convert to text,Ā  or even chat using hand writing!! The handwriting recognition is amazing, if it can even read my chicken scratchings lol

I doubt I’ll use the gestures functions much, but being able to trigger camera via S-pen is really cool and handy and will definitely get used. The S-Pen uses Bluetooth and has what Samsung call gestures, that do all sorts of great things and what it can do varies depending on the app you are using.Ā  In camera mode, you can zoom in and out, for example, as well as take pics, using the button on the S-Pen as a remote trigger for the shutter.

I can also write notes on the screen when the phones display is off, without having to activate phone or open the notes app.

So You Bought a 944

What Do I need to Do First?

First take a deep breath and let it soak in that you now own one of the greatest handling cars ever made. It is a car that was the benchmark for many other cars, like the RX7, because it was seen as the best of it kind at the time. The connection to the road is unlike most cars, and something most people have never experienced before, and it allows the driver to feel, in a more analogue way, the joy of driving, whether that is using momentum in a NA(normally aspirated) or having a blast in the turbo, which is still a very fast car despite it’s age(and can easily be modified to be even faster). So first thing is pull up a chair and just look at your gorgeous car.

First Things First

Some things should be done straight away, and if the car has no service history, some of these should be done before even turning over the motor, especially for cars that have been left sitting for many years. The engines in 944’s are what are known as an interference motor, and so if the timing belts break, the valves will hit the pistons and do expensive damage, and hence the importance of resisting the temptation to start her up and see what she will do. So first thing is to find out when belts were last replaced and if unknown, then replace them before trying to start the car. Most owners replace the water pump with every second belt change, as it is easier to do when the belts are off, so this should also be done at the same time if when it was last done is unknown.

Is The Porsche Cayman GT4 the modern successor to the Porsche 944 Turbo ???

As my loyal readers know, I have owned a gorgeous Porsche 944 Turbo for over 5 years now. The reason I can afford it is because it was shunned by the Porsche “Purests” who at the time of it’s release often stated that it wasn’t a real Porsche, afterall it wasn’t rear engined, it was water cooled and it’s predecessor the 924(from which it evolved) was seen as a bitza, using parts from Audi, Mercedes, VW and of course Porsche. They over look the fact it was completely designed by Porsche. I would like to thank them because if they knew what I know, then the 944 turbo would have been way too expensive for me to be able to afford. God bless you, one and all šŸ™‚

The 924 was originally designed by Porsche to replace the 914 and 914/6, which was a joint venture from Porsche and VW, and sold under both brands badges. VW decided at the last minute to pull out and go with their own designed Golf. Porsche decided to buy the rights back from VW and still release the car as a Porsche. The 944 replaced the 924 and used an all Porsche designed 2.5 litre engine, that was basically half of the engine used in the V8 928.

Navdy Automotive Heads Up Display

Navdy Automotive Heads Up Display

This amazing bit of technology (the Navdy) looks like it really is bringing the future to our cars. The device allows you to do all sorts of things like texting, tweeting, make calls, see who is calling you, navigate, and much more, all while keeping your eyes on the road ahead. Pilots have been using this technology for years to make flying safer, and now it is coming to your car.

The Navdy is a very clever device displays all sorts of information from your Android or Apple phone. It allows you to talk to it and use gestures to control it and will have a range of apps it can work with, all designed for use while driving. Because the display projects an image that looks like it is 2 mteres in front of you, that means you don’t have to adjust your focus to veiw it.

The Navdy is going to be a much safer way to do many of these tasks while driving, and is major technological advancement compared to the basic Heads Up Displays (HUDs) currently on the market, that are either designed as speed displays or for Navigation. The added functionality and gesture control take this technology to the next level

PRE-ORDER and SAVE

The Navdy is available for pre-order at a significant saving over the normal price that people wil once it is released. You can pre-order by clicking here but don’t hesitate as this cheaper price is for a limited time.

Make sure you check out the video, even if you are not buying as it’s worth watching anyway

Ebay Find:- Orignal release FEIT kicks

Well a few weeks ago I was trawling ebay when I decided to search for my favourite brand of kicks *FEIT*. Much to my surprise there were a couple of kicks for sale and amazingly they were in my size and very cheap. When I saw the listing I noticed they were unworn, and new with tags. I promptly ordered both styles.

Now for those of you who don’t know the brand FEIT(pronounced fight), it was started back in 2005 by the AustralianĀ  brothers Josh and Tull Price. Tull had earlier haDSC_0001d a lot of success with a brand he started back in 1996 with a friend he went to school with Rodney Alder. That brand was Royal Elastics. They decided to replace laces with an elastic panel and by 2001 they were selling around 1 million kicks a year, in 35 countries. Although by any standards Royal Elastic was a massive success it didn’t represent what Tull was passionate about, and that was quality, craftsmanship, and sustainability.

FEIT was born out of a desire to produce high quality shoes using traditional methods and high quality materials. This meant the shoes would be built to last, offer incredible comfort, and be an antidote to the mass-produced low quality shoes that have dominated the market for some time. Now I am old enough to remember my parents getting shoes re-soled at the local cobbler.

Macro Greens and Miracle Reds Super Foods

Macro Greens and Miracle Reds

I was watching an episode of The Doctors when one of the Doctors mentioned that just about the best thing you could do for your health was to drink a smoothy with Macro Greens in it. I decided to try some and bought some from a local website. I immediately noticed a difference and have been having it daily now for about 3 months now, and cannot recommend it highly enough.

I have increased energy levels, and generally feel a lot healthier. Before I tried it I wouldn’t have believed that one drink a day could have such a noticeable effect.. The Macro Greens nutrient rich super food is made by MacroLife Nutrients, and when I was looking for them I found out none of my local health food shops stocked them. I went online and found an Australian site that had them. They also had another product from the same company called Miracle Reds, which they call a cardio antioxidant super food.

I decided to order both and am glad I did if for no other reason than the Miracle Reds add a nice berry flavour to my smoothy, and no doubt are also contributing to my feeling of being healthier since taking them both daily.

I bought Macro Greens and Miracle Reds in 284.5gram(10 oz) containers, that hold about 30 servings, and although happy with the results, I was not happy with the cost of buying them this way. So I did a bit of googling and found that iherb.com had both Macro GreensĀ and Miracle Reds in larger 90 serveĀ  850gram (30oz) packs and at a much cheaper price than anywhere else I found. Shipping was very cheap too, as I was spending over the $60 threshold that gets free shipping in the US and much cheaper international shipping, iherb.com ended up being so much cheaper, that I was virtually getting the larger packs for only a few dollars more than the smaller packs from the local website

The Macro Greens and Miracle Reds arrived a lot quicker too. The local site took about 10 days but iherb.com got them to me in a few days, and with much cheaper shipping charges. I couldn’t be happier with the pricing and speedy delivery from iherb.com and would highly recommend their site for all you health food needs Click Here

IPTV on a SONY Bravia KDL46HX820

IPTV on a SONY Bravia KDL46HX820

Normally I go out and buy the stuff I review here, but this review is a little different. This time, the good people at Sony were incredibly generous, and loaned me a TV for a few weeks, to review the IPTV functionality (if I decided wanted too). The review is meant to be just about IPTV butI have to let you know about the TV too, as it was a fantastic piece of technology.

IPTV

I am guessing most people are thinking to themselves *what the heck is IPTV when it’s at home ?*Ā  IPTV is just TV or Video content, that arrives via an internet stream, rather than over the air, like traditional *free to air* that we have had for years, arriving via an antenna on our roofs.

One thing that separates SONY’s IPTV from many other IPTV offerings from other brands, is the depthĀ  of the content. Many brands of TV have IPTV functionality, but when you dig below the funky interface, there is little content. That’s a bit like having a great audio system but not having any music.

It’s very clear Sony have gone toĀ  a lot of trouble to not only provide first rate IPTV functionality, but also to secure a lot of content. When I reviewed the TV I had access to well over 20 channels of IPTV content, and that list is growing all the time, with SONY planning to add more and more channels over time.

One of the great uses of IPTV is to provide catch up TV services(this is when a TV station makes programs that have already been aired, available to be streamed via the internet). I made use of these several times. When faced with typical Melbourne bad weather day, instead of being stuck with just Daytime TV to watch, I was able to stream some great Documentary’s, I had missed when they were broadcast on free to air TV in the weeks prior.

Now these same catch up TV services are often available directly on your computer, but SONY has done deals with the TV channels to get a higher quality streams, from different servers, that look great even on a massive 46″ TV, like SONY had loaned to me. These same services, when watched a on a small laptop screen, can often only be viewed in a small 3″ window, as going full screen can make them unwatchable.

SONY also has IPTV channels for everything from dining, travel, fashion, movie previews, to how to channels and even a wiggles channel for the kids. Some of these have a lot of content while some are a bit thin, but no doubt these will be added too, over time.

SONY also has what’s known as Video on demand services too. So when you want to watch a movie, instead of jumping in the car and heading to the video store, you simply select it from the screen(you can even preview it), and watch it in HD(high definition) or SD(standard definition). The HD movies are perfect but an SD movie I watch hadĀ  a little noise. It wasn’t a problem, and was perfectly watchable, but IMO it is worth paying the extra for the HD version.

THE TV

Well the first thing I have to say about this TV is WOW! This 200Hz LED/LCD TV has a stunning picture. The colours are incredibly faithful with really deep blacks and fantastic contrast. This TV uses SONY’s Opti-contrast LCD panel, and it is the one used in all their high end TV’s, and it is a clear step up from their entry level TV’s.

The TV has built in wi-fi, which is really handy for most people, to access not only IPTV content but also to the pictures, and video’s on you PC’s, on the same network. The technology behind this is called DLNA. DLNA is just a way for lots of devices to be able to share media across a network. These can be everything from TV’s, PC’s, audio systems, to HDD’s or mobile phones.

The TV is a 200Hz model, and although I am not convinced anyone can see any difference over 100Hz (unless you use a test disc), it certainly can’t do any harm. The TV is also 3D, and although many people aren’t that excited by 3D, the fact movie makers like Scorsese and Speilberg are now making 3D movies, suggests to me, it is here to stay. The TV even comes with 2 pairs of 3D glasses.

If you are after a great TV then the HX820 is hard to go past, just in picture quality alone. The IPTV in this and most SONY TV’s is just icing on the cake, and really does give you a few more options of content to watch. IPTV clearly isn’t designed to replace free to air or cable TV but is a great adjunct to the services we already have, and well worth the effort SONY has clearly put into making it a success.

I could go into the technical features of the TV like local dimming etc but the great thing about this TV, is that you just need to look at the picture to see how good it really is. You don’t need to be an expert.
