Summary of change:
This page contains information on helping a a friend with a Audi Coupe with a 5cyl 20V Turbo enigne conversion (like a european Audi S2)... running VEMS, w/ stock Auditrigger setup and stock COP w/o power output stage and 440cc high impeadance Ford Racing injectors. ---- So far, the ECU was ordered setup for Auditrigger, and I assume that one of the grounds was bad and this is why we cooked the P259 chip (confirmed with Jorgen), so it was removed and the two diodes put in place. Before I reconnected the ECU, I reconnected all of the grounds myself (as I didn't install the VEMS in the first place, I just took over when they couldn't figure out the trigger setup). The hall sensor is recieving 5V (from PIN 28 - verified this @ the hall plug - also during cranking), the hall sensor wiring is NOT sheilded! But the original Audi harness is also not using sheilded cable (only for the two VR sensors). The VR sensors are within spec as far as the ohm readings go... One has 974ohm, and the other 1007 ohm. MT does show RPM values when cranking (between 100-180 rpm).
