My approach would be to provide safe base maps for each specific car based upon factory settings and my own tuning experience. This would get you pretty close but I would be making the fuel map rich and the ignition map retarded. I would recommend fine tuning be carried out on the dyno by a limited group of experienced tuners who have been trained on my system. I don't think theres any other way to do it right, unless the end user is very experienced. I could always stick a MAF sensor in but thats going to cost a few hundred quid in hardware which I think is better spent on dyno time.

I've decided what to do!
had a long chat with Simon Peckham today, nice guy who obviously loves 944's I'm going with his recomendations all the way allthough my initial thoughts were slightly different
Blueprinted 2.5 L with Nitrasil bores, new uprated turbo,bigger injectors,chipset but everything else stock..the whole engine bay will be made to look as close to new as possible!
Can not wait but it will be the end of the year before work starts so I can make the most of the summer when it arrives
I'm going with the KW V3 but after the engine re-build because I may do other work at the same time like steering rack, ball joints etc and it seems mad to do the geometry twice.....(I must be getting old)

Good choice Ken [

With Simon doing the work it will be a top quality job, every internal part measured and machined to the exact tolerance and he'll replate everything in sight so you'll need sunglasses to look under your bonnet
Don't stand next to him too long or you'll get plated as well []

I believe it's the 2.7 cam that gives a little more lift but I also believe it's very little, most tuners state side seem to leave the original cam in place. I'm still in two minds as to change mine or not, the standard is capable of serious power and I don't like lumpy cams. Not saying that the 2.7 is but perhaps some after market versions maybe. If anyone comes up with a good proven cam I may well buy into it, the 2.7 cam is not for me, it may have more lift but what about duration?.... If it was a good replacement for the 951 why didn't Porsche do it on their later turbo's? I bet they looked into it

None of the cams have any duration though Pete! Thats one of the problems / designed-in features. I understand that series one M44/1/2/3 cams have a little more duration on the exhaust profile, which Americans are excited about - but I treat most of what they say with scepticism...

Id love to link to a credible source, but Im afraid that I cant. Youll just have to try to endure the crap on Rennlist and Pelican trying to identify the few who know what theyre talking about, sorry.
Its only 'stuff' which Ive picked up through casual forum reading over the years. Perhaps Simon peckham will know?

Ken, I was wondering where your enquiries would lead to. My own enquiries led to SPS some years ago, mainly for a BB turbo for my then daily driver 951. Simon had a Red car which I test drove, and ended up owning. It cost a few bob, but less than a used Golf TDI and I regard it a superior daily driver.
The car was definitely better engineered than a new 951 off the line in 1989. The engine (2.5L) to this day (20k miles and 2 dreadful winters later) uses no oil. I put a Fuchs/Silkolene Oil in it as advised by Simon, and change it every 6k miles.
Up to that point I had previously run a std 220 turbo, and a 250 with a ProMax L2 kit. I wanted the next development and did consider the big capacity option, but there were too many unanswered questions. At the time, my biggest concern was that I would end up with a 15mpg borderline-grenade engine which would be unsuitable for daily use.
Simon was really helpful and understood my concern, he agreed to a test drive of about 80 miles I think, and I checked the mpg over the test. It was better than my own car! (I thought with 55lb injectors it may not be quite as good.) I have since added a 3" exhaust.
The next development of my car will be engine management........I think a world leading solution is going to emerge in Gloucestershire......

Hi george yes simon did talk at length about your car it sounds great[] ......If I've got any concerns at all it is engine management, Simon is very pro the stock Bosh system I,m very keen on the Barks ECU I think we may have futher discussions as the project goes on .........however he knows what he's talking about......I know next to nothing when it comes to engines

Ken,
I was once told; "better too much communication than too little" and that applies here, you have two really good specialists IMO, and ideally you need to get the guys speaking to each other
