I am currently setting up a VEMS V3 for my 1970 Alfa Romeo 1750 GTAm replica.
I use a Alfa 75 2 litre twinspark naturally aspirated engine.
stock 60-2 trigger wheel, stock VR sensor
running twin spark as wasted spark
VGS throttle body
Wiring loom made as shown in the schematics available from download section.
Everything works fine at the moment except the VR sensor. Sensor until EC-36 shows perfect signal.
Genboard ordered directly from vems.hu with VR as primary trigger and hall as secondary trigger (as i did not know which kind of sector i would use).
No trigger signal during triggerlog, contacted Ferenc Kulin, checked my settings (look OK), will also check my wiring.
Possible fault: P259 chip (i do not use the outputs from this chip at all), maybe i blew it when testing the hall sensor?
If wiring schematics is OK i will send in ECU for a check.
