Have you measured when the injectors...

[Lex]

The spark actually happens at the end of the pink trace (falling edge). When the signal is high, it is charging the coil. When the edge falls, the spark happens. I counted about 18 crank pulses from the missing tooth to the end of the spark event in this picture. Every crank pulse is 6 degrees. So 6*18 = 108 degrees. Since spark happens at 10 degrees before TDC, that means it is 108+10 = around 118 degrees from the missing tooth to TDC. Which is correct. Nice capture!



As for logging the injectors, nice video! That shows me the command from the ECU is enough to look at.

I can't tell from the video if the ECU moves WHEN it injects around. As you see, when you rev it, the crank pulses become faster. So this might be tricky, but keeping the missing tooth on the screen will give us the reference needed (as long as we can still count teeth). Are you logging on the scope itself or taking a video of it? If taking a video, vary load very slowly with a passenger and change the timescale as RPM and load increases so that you can still see the missing tooth.

Great stuff so far! We're getting somewhere!
