honda obd1 on uaefi

[AndreyB]

I've got an obd1 honda running on uaEFI! As far as I know that's the first engine ever running on uaEFI.

I've wired bare minimum for now only shaft position sensors and fuel pump control but that's a start

problem: crazy RPM on start of cranking and that's due to crazy VR readings on the MAX9924 "crank" channel.

This is awesome I am doing the same thing with a d16z6 obd1 in my 93 civic so far I have had it running on tunerstudio with speeduino but I always like to try something different.

Are you running the trigger as basic distributor? Also are you running semi sequential for the injectors or batch? I have a obd1 breakout adapter from dcwerx at wtmtronics.com that I'm going to use with the factory harness. Did you splice in the factory harness or run a new one?

I hope that this link answers both questions? Also please note "Honda OBD1" preset.
