Hi folks,
I have a wire running from the coil negative terminal to the high voltage RPM input (rH) on the DL-1. Another wire from the coil goes to my rev limiter/shift light (works perfectly).
I'm getting data, but it doesn't seem remotely accurate. Climbs slowly to 8000rpm, then drops and spikes up and down around 1000rpm. Not remotely related to engine speed.
I've read the knowledge base sections here & here:

I have the earth (rG) connected just to a chassis earth - should I try running a lead to an engine earth?
Please tell me I've just got something totally wrong.
thanks,
Evan.

Here's a screencap of analysis - RPM at the bottom.

Hard to say. Signal strength? interference?
Do you have another option? fuel injector trigger wire? ECU feed?
If not, you might have better luck with the MSD GMR pickup.
