Strange Oscilloscope Reading on Nano

Upon reading your post, I jumped up and hustled to my bench, thinking "aha",
But lowe it is in the program. It got skipped here when I coppied.
Thanks; it could easily have been.

I want to read my injector signal to power a parastaltic pump.
I can do it easily from the MAF sensor, since I've done it before.
But using the injector signal would be supreme.
That what this is all about.
