Honda b Series trigger problems

Post by Koullisgg »

Merry Christmas to everyone
I hope you’re all having a great holiday.

I’m looking for some help with a trigger issue on my uaEFI ECU.

Setup:

24 teeth connected on C16–C17

1 tooth on C18–C19

I don’t get any trigger errors, but I’m losing RPM — especially at low idle and above ~2,500 RPM when using the 12/24 trigger.

I also tried a custom setup with 24 teeth on the cam, but sometimes the engine starts with incorrect timing and I can’t figure out why.

Has anyone experienced something similar or found a solution?
Any help or ideas would be greatly appreciated. Thank you.

Your trigger setup is wrong. Proper trigger setup is in the FAQ at https://wiki.rusefi.com/uaEFI-Honda-OBD1/

i did not find any logs or tunes links in your question, without any data I have to rely on telepathy

telepathy has shown me https://rusefi.com/online/view.php?msq=1793 which uses wrong trigger setting

it's hard to help based on zero hard info
