It looks like there is interest so I will tell my friend to start working on the 96 ECU.
I think the best approach is that we first test a prototype on my 993 and dial in some base ignition and fuel maps. I estimate this take a couple of weeks.
Once that is completed, I will ship the prototype to someone over in US to try it.
It must be someone who is willing to spend time on testing it and must have a professional tuner with a dyno close by. I would be really happy if it was one of the tuners that frequent here on RL (like Viperbob, Bill Verburg etc.)
If the ECU is deemed good, then my friend could start making them for sale. I think earliest that could be by summer time, depending on how everything goes.
He propably cannot make more than 2-3 ECU's /month.
We have to keep in mind that this is only a hobby for him, he's got his dayjob as a research scientist in automotive industry (vehicle electronics RnD) and his also got two little kids and a wife who need some attention too...

This is different from a chip from the standpoint that this would be a complete replacement of the original system with a totally new processor. This is more akin to installing Motec, or a universal DFI kit, but without the mess of re-wiring.
Sounds like fun!

A chip is something that is pre-programmed and inserted into the ECU (not possible on 96's). The maps on the chip cannot be modified on the fly.
There cannot be any promises for power gains. It is all up to the engine (including intake, exhaust) and the tuner.
My understanding is that Porsche left some hp/tq on the table with the stock fuel and ignition maps, mostly due to emissions etc.
So yes, there probably is some power to gain from a stock engine but I think this is better suited to modded engines and not only for getting the best power out but to guarantee a proper air/fuel ratio (important for the longetivity of the engine). Which was actually the very reason I put Motec on my car in the first place...

However, Motec M600 is about 3000USD at the moment I believe? (I paid 2000euros but I got it cheap at the time) so that is why I think there might be interest for the ECU my friend could make.

I'm interested. Would also be curious to hear from experienced engine software guys what exactly the benefits are of an entirely new ECU (it's not Motec -- so what kind is it?) versus programming a chip. For example, I sourced a '97 ECU for my '96 993 that I'm planning to use for when I freshen up the motor and do RS cams or 9M top end. Are there limitations to the flash-able Motronic ECU that don't exist with a different, more modern, computer?
I guess the question really is -- Is the benefit of an aftermarket ECU simply the fact that it's programmable while the stock ECU is not, or is it that the programming resolution for fuel/ignition maps is superior to stock?
