Miller performance has cracked the obd1 motronic and made it possible to Write and Remap obd1 chips. Now they are strictly bmw but have joined with 034 in development for audi. Now thats all fine and dandy but I want for obd1 abas.. 16vs and vr6 cars(digifant ?). 034 is getting close to releasing the "WAR" chip for audi. I called them today and they asked me to gauge interest from my fellow enthusiasts to develop these chips for obd1 VW engines. Now i am sure this is no HONDATA as the early motronic isn't as advanced as the honda computers.. but it would be a great tool to get your car tuned as close to perfect as possible without the use of standalone. The e30 guys use it to ad boost on m20s so i do not think it would be an issue for adding boost to a vw.
FYI.. i stand to make any money by posting this thread.. just throwing it out there..
