Megajolt E

What is the electrical signal at the Tach RPM lead.

Attempting to use this signal to tie into my Bosch Fuel Injection System on my 1981 Fiat Spider with no success.

The Megajolt RPM signal will replace the signal that was connected to the engine coil, now removed as part of my Megavolt upgrade.

Is it possible to pick up a signal from the EDIS instead of the Megajolt controller?, where might i find info on the EDIS pin voltage output?

The tach output on the Megajolt is a 0-5v square wave. your EFI system might need a different kind of signal.

The EDIS module has an IDM output on pin 2 - this might help: http://www.dainst.com/info/edis/edis.html

Hope this helps!
