I think dwell is to low try something between 2.0 - 3.0 msec, be careful check temperature on ignition coils.
2.4 seems to work better then 1.8 msec
And AFR looks very rich I see 12.00 at 13000 rpm.
Maybe change your settings so AFR is around 13.5 at 13000 rpm.
according to my observations, on a throttle 90% AFR 12.0 produces the best power.
The operating time of the spark changed 1.5-3.7 milliseconds. I did not notice a special difference, apart from a strong heating of the wiring.
It just seems to me that speeduino stops registering engine speeds above 13000. If it is not critical for the operation of the injectors, they continue to pour fuel, but for the formation of a spark it is critical.
Dwell, seems like you worked it out already.
Can you set the crank sensor filtering to off ?
Any change to measure ignition timing at 13000 rpm ?
At 13000 rpm every crank revolution only takes 4,6 msec !
I turned off the filtering of the crankshaft sensor. Judging by the logs, speeduino does not record rpm above 13000.
I continue to use standard ignition for now.
I plan to try again to the semi-sequential injection option and not use the camshaft sensor, I'll see what the results will be.
