for whom it s intresting: the problem was solved by trigger wheel replaced from crankcase, and new trigger wheel design is 24-1

Adam, is it success? Time to road tune?

420kOm 9300rpm

today we will try to implement 220kOm resistor, result will be here

Thanks for recomendations, first we decide to try with resistors. look at attachment, its 8100rpm with 120kOm resistor on the positive wire, looks pretty good?

Actually we cheked smth, before link installiation we use other ECU, with all current configuration, everything was ok. Old ECU has resistor on inlet signal crankshaft trigger 470kOm, link, i found 22kOm, i guess its a possibl reason of it?

Hello Adam. Thanks a lot. way #1 increasing the gap not effective, allready done many times. way #2 and #3, i think it s too much expiriments, result is accidental (all the more so OEM crank trigger whell installed inside the engine block, dyrictly on a crankchaft ) I guess the best way is change the thrigger wheel (replace it from engine block) and sensor type (for example hall sensor). What do you think about? If you are agree whith me, what design of trigger wheel and sensor type are preferred for 100% guarantee of effective work on 9500-10000rpm?

Hello, what p/n sensor? which max rpm do you use?

Trigger Scope Log 2022-06-11 3;54;52 pm.llgHello guys. Sorry for my english)) Try to explain my proplem. I have drag race car with opel c20xe engine. linc fury ECU. ignition 4 AEM smart coil, crank sensor- stock reluctor (gap change from 0,8 to 0,4mm), trigger wheel 60-2, cam sensor- hall, installed on cam shaft. Fuel we used Q16 AFR 10,5-10.7 problem start with RPM rising. RPM limit activated accidentally, in area 8000-9200rpm, we need to rotate 9500rpm. in log it shows abnormal rpm numbers like 16000rpm, 64000rpm wiring polarity checked according manual (NEG and SHIELD on SHIELD/GROUND, "+" on TRIG1), wire "one pice" from sensor to ECU. Trigger filter 1, try 4- no help. in the FAQ tolds about OEM trigger whell problem with "missing tooth", we modify it (see attach), nothing change. On oscilo its picture on dyno approx 8500rpm. arming thresold move up and down, nothing changed. one thin- we change DWELL time on the coil from base 3 to 5, it moves our problem approx on 1000rpm upper (before rpm limit activate on 7800-8000rpm) which way do we need to go?
