#2537, "RE: MSnS V3 Board Tach Spikes Fixed!" In response to In response to 10
Oh man...
I hooked everything up to put the MegaSquirt in complete standalone mode. Made it so I don't use the stock ECU for anything other than the alternator voltage regulator. I ran a 5v output from the MegaSquirt to the crank sensor's power, ran the signal and ground to the MegaSquirt in a shielded pair, and I still get f#@!ing random tach spikes!
Is it hopeless? Is your setup w/ spark still working for you with no spikes corbin? I thought it would be a lot of work to try your method with ner saying it didn't help him, so I thought what I did would be flawless, but I was wrong.
I just dumped $3k and 4 months (on top of what I already had) into the motor, people who've done the same know the anxious feeling you get wanting to drive it.
