advice s54 trigger error

[Kamuto]

hello, mapped today bmw s54 engine, one small problem, I'm getting trigger error at 8000 rpm, less primary, I need advice what to do with 18k pullup resistor, do I need to lower it or make it bigger?

Hello Kamuto,

Lets start with the basics first; Could you make a triggerlog of engine cranking (without injector & ignition fuse) 8-10 seconds so i can review basic trigger setup ?
After review i will elaborate on the best path to fine tune your trigger hardware (if needed).

Best regards, Dave

everything is fine with that, it's running, it's making good power, both vanos are working correct, just at ~8100 rpm I'm loosing primary trigger, at this moment sadly I can't do it, car is at the client, with 7900 rpm rev limiter. I'll try to do that when it will be possible.

so, replaced 18k pullup with 35k one, now it revs to 9000 no problem, what can be improved to spin it till 9500? after 9000 trig error again :D
