Cam sync trigger tooth jumps at higher rev with V3 on C20LET

[Stefan]

Hello, I have a Camsync issue at higher revs. My Emu black V3 runs fine with engine but i cant find the issue at higher rev. After changeing from classic (with serveral filters running fine) to black V3 i started VR prim trigger with 1k pulldown. Engine was fine up to 3200 rpm , than Camsync tooth jumps up and down and inverted sync phase → Missfire. I switched to 4k7 pulldown, than the issue occures at 3600rpm. I added a 10k resistor in line with VR sensor , now it happens over 5000rpm.

Does anybody have an idea whats wrong?

set option disable camsync above for example 2000 to check if the problem is with primary trigger or with cam sensor.

Hi, thank you. Today i checked out your advise and set camsync stop at 2000. I had only a few chances to rev higher the engine, but untill now there was no failure again. so what does this mean? Is a problem at VR prim trigger or at the HALL cam trigger. At all tests only changes on prim trigger caused changes in behavior.
