I have tried both a rising edge, and falling edge input capture, and also tried changing the polarity of the vr sensors then retested both falling and rising edge again. It is a distributor setup with a single coil, testing the timing with the light connected to the #1 spark plug lead. I have a few years experience with tuning but this is my first time wiring in a standalone ecu so the trigger input are still new to me.
I also tried adjusting the vr sensor threshold table up and down +-1.5v with no change
The car idles smooth with the rising edge input capture but I could hear audible detonation while driving
I have a hondata s300 v3 that I tuned previously with this car and switching back to it the car runs perfectly again and timing does what it's supposed to.
Pretty stumped at this point and would love some help, especially anyone who has a successfully running obd1 Honda on uaefi using the built in VR conditioners
Attached is screenshots of a trigger capture log, screenshots of my trigger settings, VR threshold and also the wiring schematic showing how I wired everything. Also the whole tune file in case there's a setting I'm missing. Thanks in advance!
