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 have tried the recomended onece in the QA what exactly is wrong with mine ?

what exactly is wrong with mine ?

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

My apologys sir am kinda new to this and also its been some very busy days

Here this is the map am using now the car works fine but i just ignore the 1 thooth after 750 rpm basicly i just use it to get the rigth timing phase and then i ignore it as it had sync problem
