I have already a V3.8 ECU with auditrigger inputs/camhall inverter and i would like to install this VEMS to a 4.2 V8 ABH code engine.
The engine has 3trigger like Audi AAN.
PRimary (VR)trigger, RPM sensor are sensing 136 yes 136 teeth on starter ring
Secondary (VR) trigger are sensing the TDC point. 72° before TDC.
Third trigger (HALL) sensing the camshaft signal. 1 small window wheel, like on 3B or AAN.
272 teeth on full engine cycle, next trigger teeth 34.
Please confirm me that i can use this trigger system with VEMS.
Audi trigger divider= How much should i use? I tried to calculate some way but i couldn't.
Thanks
