5cyl audi engine install by Claudio, in Canada

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:

Injector's are connected to the following outputs:

Inj 1 - EC36 Pin7

Inj 2 - EC36 Pin19

Inj 3 - EC36 Pin8

Inj 4 - EC36 Pin20

Inj 5 - EC36 Pin9

The Coils are connected as follows:

Coil #1 - EC36 Pin35

Coil #2 - EC36 Pin33

Coil #3 - EC36 Pin34

Coil #4 - EC36 Pin36

Coil #5 - EC36 Pin11

Fuel Pump is connected to EC36 Pin10 (IGBT Drive_07)
