Just a review of Russell's work that I've seen so far:
I've tried the 944 NA chip in a couple cars now and its a very worthwhile purchase. It seems like a silly description, but it makes the car idle and rev more like a modern car. By that I mean that it is much smoother and more responsive. It also made the car sound better for some reason. Not sure why... Either way, if its legal in your class or its just a street car: get it! you won't be disappointed. However, if you care about saving $3 at the pump and/or are intimidated by electronics and "computers": move on. You do have to open the ECU and remove the old chip. It was easy for me, but so is building computers.
951 DMEI: this thing was an awesome upgrade for me. I got all of the benefits that the 944 NA chip got me, but in the turbo. Related or not, I finally beat my most fierce autocross competition (running autothority chips, and after 5 years of being 2nd place and ~1sec behind). I haven't gotten a good fuel economy reading though as its so fun to step on it whenever I get a chance.
I'll be upgrading to the 951DMEIII in the coming weeks. Can't wait!
It should also be especially noted that Russell is making constant improvements to his products and is looking to expand his product line to cover more than motronic Porsches. Great guy to deal with!

Not to steal the thread, but Ive got an N/A 8V and was thinking of switching out to E85 fuel. Any chance you might consider tuning and selling a chip for an E85 car? Perhaps make a kit and throw in some bigger injectors, fuel fittings, and a chip as some kind of package?
It seems like the N/A motor could perhaps pick up a little torque and power from being able to change the timing a hair, and getting a cooler charge for combustion...
The only thing that holds me back from doing this is that I dont want to switch out to some kind of stand-alone, and Im not competent enough to reprogram Bosche's DME chip myself...

I can't really quote you exact performance gains over what you have now, probably another 8RWHP. You would have to run at least 93 octane, but can make 100 octane version if you have that available. Everything will wear out quicker, fuel will cost more...
So much for being a salesman...

Not worth the trouble.
Russell, what is this about "race" chips now? Looking forward to that selector; but I would definitely prefer being able to switch it with an external electronic switch instead of having to take the kick panel out.

My personal engineering opinion, but E85 would eat your fuel system alive. There is no part of the fuel system in a 944 that was ever intended to have corn juice put through it. I mean, Germans in the 1980s would have thought that was a pretty funny joke. I think you'd be going through fuel pumps, filters, gas tanks, fuel lines (fire, fire) in an accelerated fashion.

The street chips give the most area under the curve, the most power across the board reliably and safely. Lots of margin of safety in them. The 93 chips are a bit more aggressive, the 100 octane chips are considerably more aggressive, all are for off road use only, of course...
