Toyota Supra mk4 1994 2jz gte
Engine:
- Stock 2jz bottom end with 1jzgte head.
- Single turbo 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
- What ignition plugs? You must use resistor type plugs.
- 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 runs, but above 3000rpm the cranktrigger seems to see to many missing teeth.
- It seems to be poorly mapped above 3000 rpm, it is hard to judge if what you're experiencing is simply a mis-fire from running too lean/rich. Enable +/- 20% EGO correction and do some auto-tuning. You can manually increase the cells above atmospheric and at higher rpm to get it done faster.
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 1.2.11. 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.
Config: Not necessary, the vemslog file contains full config and live changes.

- Please add log file of cranking the warm engine, let the lambda sensors heat up, and then drive around or rev the engine to show the trigger error you speak of.
