I wonder if i will have an issue using my recently aquired millenia coils with built in ignitors and not being able to get a tach signal?

So this should work right guys?

yeah or just try it in the diagnostic box, -IG to the 12v source +B

I haven't hooked up my tach for over a year, the rev limit in MS will stop me if I've gone too far....I can go by sound to give me a rough ball park anyways.

It definitely ain't the same as the 1.6s if that's the case. The 1.6 igniter has a black/white wire coming out of it that feeds back to the ECU, however the tach signal is a yellow/blue wire which goes from the igniter to the tachometer and the diagnostic connector. On my car (MS, full standalone) I left the yellow/blue wire alone (still goes from igniter to tachometer) however my black/white wire is completely disconnected.

I'm just glad there are some smart guys on here that can figure this stuff out. Good job guys.

IGF is your tach signal. You'll need a pull-up

add that pic to the archives for standalone MSI in a 94-95 cuz it fucking worked. Thank you Chad and Scott, no matter what OG says about you 2 you're OK in my book. :bowdown:
WOOT! Anyone happen to locate the pin on the 1995.5 tach wire on the boomslang? :mad: Position 2I has no wire on my cars ECU harness. I'm guessing but haven't had ANY time to check it out, but I'm guessing that its position 1F because my documentation shows its not used but I think theres actually a wire there. |
You already fixed your problem, but I just want to feel important. :)

For the benefit of other owners, I just BLK/WHI to 12v via a 1000ohm resistor, and I now have a working tacho. That saved me from having to duplicate the circuit I used to provide a working tach for my Haltech.
