i don't know where this 246 trigger angle comes from, both my m43 run -114 trigger angle.
one is paired injector and COP the other is setup sequential injection and coil.
I can send the tune if you like but its NA only, but if everything on your engine is correct it will start it.

the one thats paired and COP is a Pazi88 board, with the base map, i plugged it in and fired it up and ran first go.

246 - 360 = -114 Both give same trigger angle. Those just change the phase for sequential inj/ign if used. Witch batch fire and wasted spark, both work same.

Having same issue like this on a m20 and m40. Trigger angles should be correct but even with 0 advance cylinder 1 is not line with timing mark

So change the trigger offset until it matches...

That's what you do.

I should may make a new thread but i'll write here instead

I had exactly same problem, cant get it run with 246 or -114 (theyre basically the same), cant get it run with anybody's m40 tune either

Brought the car to a shop, they use timing gun and the speeduino had the timing inconsistent i thought maybe the vr conditioner was bad, i dont have paid TS so i tooth logged it using logic analyzer and i got the last tooth high at slightly different period

https://ibb.co/dDQW06c

blue mark is the last tooth, red mark is the missing tooth
i'll try to adjust the hysteresis on the input off the op amp now
