I'm just planning my megasquirt installation, and rather than messing with tacho driver circuits, I was thinking of using the EDIS unit pin 2 which is a tach feed back to the ECU as stock.

Is anyone doing this, tried it, have any experiance etc??

Cheers.

i've done it, drilled out the blank and shoved a wire in the hole worked for years

i used pin 11 but to drill out the blank and move a wire

Not sure which pin number it is, but it's the one between the coil wires on an EDIS4. It works perfectly well. As said, if the original car didn't have a tacho the pin will be blanked but you can take the connector apart and fit your own wire in the position.

It's how I run my tacho.

which version of ms do you have? my ms has a tacho out which gives exactly the same signal as the edis4
