- stepper IAC valve
- 4 bar MAP sensor
- HALL crank sensor

My plan is to use the stock trigger system. It is important because the race rules don't allow to modify it and mitsubishi EVO-s are more than 90 percent of the racecars here. It's a very big market.
Here is the stock crank triggerwheel. It has two simple big 67 deg tooth, The falling edge of the tooth is about 67-70 deg before TDC:
And here is the cam trigger. The proble is here. There are a bigger and a smaller tooth on it, i don't know the exact TDC position yet:
My question that is it possible to use this trigger system with vems? Or maybe make some little board to modify the cam trigger signel to be seems only one tooth? Because on that way it could be a simple 4+1 trigger system.
