cachanilla86 Posted July 17, 2009 Share Posted July 17, 2009 I was wondering, since Im on a very tight budget, how to keep the stock 280Z gauges when swapping a newer engine. I'll be swapping a RB20 running on Mega Squirt, but I dont have any Idea on how to keep the stock tachometer. I read on another forum, a guy made a simple circuit to emulate the pulses to the Tach, but he posted no pictures of the circuit, can anybody help me? Thanks.

TrumpetRhapsody Posted July 17, 2009 Share Posted July 17, 2009 Check out the megamanual(.com) for how to do it on the ecu, or search around hybrid for how to combine the coil signals and send that back. I've seen it done both ways. Quote Link to comment Share on other sites More sharing options...

The original tach got a signal from a singe coil. EDIS just uses more than one coil. Just take the original wire from the tach and plug it into all the coils. You need some diodes so the coils don't ground each other but that's it.
