I hadn't thought of that. The most I could get out of it was about 9hz no matter how high the rpm was. On an hei, I got consistant sharp peaks. On a wasted spark it was small and varied between plug wires. I'll turn up the sampling rate first to see if it helps at all. Then I'll hook to the...
I'm trying to use an inductive clamp from a timing light to pick up RPM signals for a chassis dyno. I need <10V but enough for the Dataq DI-148U I'm using to read. I've tried finding a usable signal off the timing light itself, and an AD8230 in-amp in a couple different configurations. With...
