Not to make things difficult, but could the folks who have replied (or plan to) include a url or other info regarding the EFI system. I'm very experienced in tuning Bosch SEFI based systems - mainly modifying the OE Ford (which is all Bosch) engine management systems. I an 110% certain that I could take a Tarus V6 ECM, MAF and wiring harness along with a plug-in interface (
www.eec-tuner.com - I've used these on 3 different cars including a 670HP n/a road race mustang where I totally modified OE Ford program), and adapt it to a 930 motor. I'll bet that is what most of these systems are - either speed density or mass-air Bosch systems with Ford harnesses.
