I used ardu-stim but found that 24x signal invalid for p59
I measured OEM tone wheel (from gen3 LS) and found that teeth and gaps not match each other in length so ardu stim uses wrong timing to emulate crank sig

I'd love to know for sure how it calculates sync. I assume there's a list of short/long or 1/0 that it uses to determine upcoming cylinder, and that it compares tooth to tooth time with just tooth time similar to how a Gamecube controller sends/receives 1s and 0s with only 1 data wire and no clock. Imagine the GameCube controller had a variable data bandwidth and think of that as the crank sensor signal. I could be wrong, but that's the best guess I have.
