Summary of change:
I already have a VEMS V3.8 ECU with '''auditrigger/camhall inverter ''' (suitable for VR/VR and VR/auditrigger) Planning to install on '''Audi 4.2 Liter 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. ** Camshaft HALL window for masking sectrig. 1 small window wheel (short 0V and long 5V ?), like on 3B or AAN. ** note: this is NOT the same as "third trigger" (third and fourth and fifth triggers are connected to specific inputs) '''272 teeth on full engine cycle, so 34 tooth between events''': * divider=17, next trigger tooth=2 (I would use this first, after the divider, setup is similar to c016 : 16 primtrig pulses for 1 sectrig pulse) * divider=2, next trigger tooth=17
