BMW vs AUDI vs Mercs? None of the above: Porsche 😉

Red sounds like my engine builder. But there's a lot in a Motec that I'll never use as a street car.

Who`s gonna tune it? 
None of the above and that is exactly why I didn`t mention Porsche :))

I`d, probably go with Adaptronic, which is cheaper than the most and has really good support. 
If you want a chat with some one who`s been there a while ago and has no intention to sell some stuff (no affiliation)- give me a call "0 four two five 008 55 one" George

this is what i found. they can run things like VVTI etc, all sorts of high tech stuff you find on modern motors, that i simply would not use.

i would have loved a motec and it does do things better than a haltech, but end of the day the haltech is ahead of the stock ecu by far and it is just a close to stock 2 valve six cylinder nothing crazy.
if i had done a crazy 3.8 build with some more goodies in there for sure i would have shelled out for a motec.

adaptronic was high on the list for my tuner, he says they do things like fuel mapping better than haltech, for about the same price.
as i said before, the only thing holding us back was doing events interstate and possibly needing repairs etc.

Sam,

I managed to buy a plug that fits the body harness socket and have used this to make a harness adaptor.  Unfortunately the standard ECU for 3.2's are so basic with batch fire injectors and not much more that the new auxiliary harness has had to have around 30 conductors to cover all the extra sensors, CoP's etc and even with using the thin Tefzel insulated conductors has ended up the same size as the standard harness!  Have also found some problems with the accuracy of the wiring diagram in the Bentley workshop resulting in having to do some repinning. 

Have you finished your tuning?  Care to post a bit more about your ecu upgrade?  I reckon there are a few of us who would be very interested!😊

road tune is done. drives great. the jenvey kit is very well designed. the haltech 'does the job' there are better ways to do it, better/smarter ecu's, but support and accessibility were key, and my engine is not wild.

dyno tune in the next few weeks once we do the nut and bolt check to make sure everything stayed in place. started at 243rwhp will see what the ITB's and ECU add.

Looks nice, mind sharing ignition and AFR maps?:)

I`m using EMS, but Red is not that happy with all of above (except Motec I guess)

With ECUs you get what you pay for and there is plenty of junk at the bottom end while at the top you have Bosch and Mclaren Electronics. 

———————-

Ill add a bit on Knock as it is a very extensive subject that needs a book to cover it.

Again you get what you pay for. Knock comes in levels from nothing to extreme. The trick is to detect it before it does any damage. Knock is measured indirectly by various means. The most common worst performing and cheapest is a microphone type sensor bolted to the head or block that listens for the sound frequencies that indicate knock may be present. Problem is that it can also hear every other sound coming from every part of the drivetrain including ancillary equipment and the gearbox. The signal(knock frequencies) to noise( everything else including some at the knock frequencies) is very important as we need to detect knock at very low levels before it becomes destructive. This task is often impossible using bolt on the head microphone sensors in race engines or older engines not specifically designed for knock detection. Various methods are used to improve the signal to noise such as only listening in a small window of crank rotation when knock is most likely to be present and at its strongest. This also allows individual cylinder detection and control which is far superior to just retarding the entire engine. 

Then you have more advanced detection systems all aimed at improving the signal to noise ratio such as a microphone sensor for each cylinder that has a direct sound path to the combustion chamber such as sensor under spark plug or a sound bar systems. Then you have direct cylinder pressure measurement to detect the pressure waves that are the telltale sign of knock.

The other aspect is that you (must) tune your knock system if you want to get the best from it and this involves making the engine knock and possibly destroying a few before you get it right.  OEM’s use direct cylinder pressure measurement to tune the bolt on microphone system and ensure it works.

So all knock systems are not equal. While they can all detect extreme levels of knock very few can detect knock before it becomes destructive.

I know this is an old thread … just wondering if you are happy with the results you got ? I’m considering doing a similar setup on my 964 ? Worth it or not ?

It was a long and painful road. I had my engine rebuilt twice in a matter of 12 months. And that was after the car being on chocks for 5 years. The first rebuild was an utter disaster!

The second rebuild was done by PR Tech. I kept the original ecu. I've had 10 months of happy motoring. 250hp at the rear wheels.

Wow, that's not a good start.. but thank fully it was sorted in the end.
