This page contains information for Audi Coupe with a 5cyl 20 V 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.
ECU was ordered for Auditrigger
• firmware revision 1.0.38
HALL sensor
• measured OK: 5V (from EC36pin28 - verified this @ the hall plug - also during cranking)
Crankhome VR sensor
Though MT does show RPM values when cranking (between 100-200 rpm)
• using 22k pullup resistor to 5V
• "pullup for the crankhome was changed to 43k ohm resistor as well
• without this 22k pullup I wasn't able to get any rpm signal to the ECU
• decreasing this 22k to 10k could help getting rid of the noise
• All the grounds have been checked and are good and all are connected. OK, so installers made very strong grounds very close to EC36. 1 GND + all 4 GND connected with min 1mm2 wires max 30 cm from EC36 (possibly just 10cm).

The VR sensors' resistance seems fine:
• crankhome-VR sensor: 1007 ohm
• 135-tooth: 974ohm
Updates:
I have changed both VR sensors, and verified that both work prior to putting them in. We also replaced the hall sensor with a known good one.
Also I have spare ECU with firmway V 1.0.53 .
1. Still receiving Trigger Error
2. I have on 2 cyl spark
3. I have on 5 injector's fuel
4.
I have captured a mmd0c log which can be viewed here:
