Swapping from speeduino to uaefi. No spark output on b15. Same dwell settings. 5ms cranking, 3ms running. All sensors read fine, spark output is set to "default", as i'm boldly assuming its the common 5v going high to charge and going low to discharge/fire coil.
Attached is rough starttune (i know fuel is disabled) and log of cranking. Running day740 official firmware.

Re: UAefi no spark
Is not OBD1 honda unusual in terms of using low side output to control ICM?

Re: UAefi no spark
Bog standard golf mk3 coil going to distributor. Running 36-1 crank wheel. On speeduino coil ran going low, i.e. going high to charge coil for dwell, going low to fire coil.
I just checked with hardware test, coil outputs perfect hot spark.
Plug speeduino back in, runs perfect.
Attached is log from right now. Car is sitting on charger as well. Cranks fine at ~210-220rpm, batt voltage being decent. Just no spark, and no Ign:cut code either on the log. Same tune as first post, just upped the dwell on low voltage a bit to make sure.

Re: UAefi no spark
https://github.com/andreika-git/hellen-one/issues/378 created since that could be an issue.
We know that current design has worked on dozens of vehicle. That makes me wonder if something else is contributing here.

Re: UAefi no spark
in order to confirm 50mA theory would you be able to please add TC4427EPA or something between uaEFI and your igniters?
