I did test on car. Car works good, but trigger error is allays on(bad sec trigger position)


I have a car with Magneti Marelli cam (VR?) sensor(very hard to modify cam sensor), 3 sectrig teeth.

1.1.89 (and newer) firmware supports this

Also should be good for the modified Cosworth, which using 36-1 crank trigger wheel, but need to use the original 2-tooth secondary trigger!

Trigger details


When is this strategy not applicable ?
