bryan01 Posted May 15, 2007 Share Posted May 15, 2007 i put this in the rb forum too, but nobody there seems to have a squirt and i cant find anyone online who's set one up on a rb yet so it's kindof bugging me. i'm sooooo close, it almost caughed to life tonight, but didnt. anyways, all my sensors are reading correctly, tps, clt, ait, map, o2 ... but rpm says 0 all the time. i dont think i've got it hooked up to the correct wire. i looked at a pinout of my ecu, found the "tach signal wire" and tried that, didnt work. i came on here and found someone saying it was a different wire, tried that, same results ... then people are saying i need to hook it up to the negative side of the coil ... the rb has coil on plugs, so i've got 6 coils ... how do i do that? i saw below about how to wire up an edis with multiple coils w/ resistors etc, is that how i am supposed to wire this up to get a signal? help Quote Link to comment Share on other sites More sharing options...
bryan01 Posted May 16, 2007 Author Share Posted May 16, 2007 i just got an rpm signal (and thus fuel flow at cranking) by wiring the rpm wire from the MS to one of the 120 deg. crank angle sensor wires going to the ecu ... see the rb section ... once i figure out my cranking pulse widths i'll post up some tuning info on the rb25 ...

Matt Cramer Posted May 16, 2007 Share Posted May 16, 2007 The biggest problem with Megasquirt on an RB is the ignition pick-up. It uses slot length to identify cylinders rather than a missing or extra tooth. EDIS is definitely going to be the easy way to do this. Another relatively simple way to get Megasquirt to work with the ignition is to use an Autronic trigger disc: http://www.autronic.com/page_files/trigger_disks.htm Quote Link to comment Share on other sites More sharing options...
