Toyota Supra mk4 1994 2jz gte

Engine:

-Stock 2jz bottom end with 1jzgte head.

-Singelturbo and custom intake manifold.

-Stock 12 teeth cranktrigger has been modified to a 12-1 wheel(grinded away 1 teeth)

-I don't use camtrigger(running wasted spark)

-Crank trigger sensor HALL(Honeywell GT101)

-VW Coil on plug ignition

-Lucas LowZ injectors

-VEMS 3.?(ordered 2013-03-25) ECU with Active LowZ flyback

-CLT & IAT sensors are BMW stock(bosch)

-Wiringharness custom(no shortcuts where made, done strictly by the book)

The car runns, but above 3000rpm the cranktrigger seems to see to many missing teeth.

I was running on a VR at first with the exactly same results, but changed to HALL in order to get a stable trigger.

I also tried to change the wiring harness to VEMS 6cyl prebuilt harness with no change.

Tried diffrent firmware also from 1.1.91 up to 1.1.21 No success, all the same.

Update:

Disabled PWM of the injectors and added a resistor to every injector (configured in vemstune as highZ)

No success. Still trigger error above approx 3000rpm.
