I had a gotech pro-x in my supercharged 944. With a moerse expensive crank trigger running 60-2 with not quite batch fire on the injectors ( iirc 1&4 2&3 paired together) running a single coil on a fixed distributor ( all 944's have a fixed dizzy). The possibilities with the software is very impressive, with correction maps for temperature, battery voltage etc. a fantastic product, but the problem is the cats that tune them. They tune them like a mechanical advance & sidedraughts. To properly tune one of these things will take you a long time on a load dyno, then months of trial & error with the correction maps. Not an easy feat. Makes you appreciate how even something as basic as a mk1 fuel injected gollof or a old corsa is sorted out in the mapping department. (Cold starts in joburg winters & durban summers, driveability etc) It is doable, my '44 was pretty sorted eventually, but it must have been 5000km of road testing, tweaking, fiddling, swearing and repeating the whole process. Believe me, stay far far away from them if you dont understand tuning and cant tune them yourself, because i will go out on a limb and say there is no fitter of these things that will go through the effort of sorting them out 100%. It is a shitload of work. Full load mapping is a walk in the park. Its getting optimal fuel efficiency , driveability and idling/starting that will have you pull your hair out. The general customer for these things is the dude who stuffes a 700hp 2jz turbo motor into a box shape corolla and tears up the strip at tarlton on weekends. Pity really as with proper tuning i think these ecu's are vastly superior to the stuff the e28 m5's, even the e34's and the like came out with. ( much faster processors, ability to do much finer tuning, better resolution on the maps, less interpolation etc. ) The only drawback is to map one of these sumbitches properly will probably cost more than the purchase price of the car, and that was if you found someone knowledgeable enough to do it for you.
