    Verifying RPM signals for tach and ECM from ignition module

    Update. So I borrowed an old ign module and coil pack from a buddy. Same issue. Then I realized I do have another cluster laying around. Tach works on that one, so its my tach for sure.

    Verifying RPM signals for tach and ECM from ignition module

    I'm kind of thinking the same. I've used borg warner and crappy autozone units (A1 Cardone) in the past with zero issues on the tach. I'm kicking myself because I recently threw all those old ones out. Sure, they had other issues, but at least I could have tested the tach output. I'll call...

    Verifying RPM signals for tach and ECM from ignition module

    Thanks Bob! I'll do that and see what happens. Question, is the signal from the tach pin different from the EST pin? If they are the same signal, I may try jumping the EST pin to the tach input to see what happens. I feel like I lost tach signal after I replaced my ign module with a new one...

    Verifying RPM signals for tach and ECM from ignition module

    Welp. Turns out somehow both my gauge clusters are bad because I hooked up a autometer tach at the dash and it reads the signal fine.

    Verifying RPM signals for tach and ECM from ignition module

    I will try that. I got another module under warranty and still nothing on the tach. I have full continuity to the pins on the module from the tach connection, so either I got another dud or its not connecting somehow.

    Verifying RPM signals for tach and ECM from ignition module

    Ok I just checked continuity and yes pin E goes straight to the tack wire under the dash. Looks like time for me to get my ign module warrantied.

    Verifying RPM signals for tach and ECM from ignition module

    Would I be correct when I think that pin A on the ignition module (EST) provides the RPM signal to the ECM and pin E goes to the white tach signal wire under the dash? I am trying to track down an issue where my tach no longer works. I checked my connection to the harness in the dash and it is...

    2018 Is gone. What did you do . .

    Let's see. Got some 18" GNX repros. Lost 3rd gear. Proceeded to take the trans apart myself and spent hours...and hours...and hours on the phone with Dave Husek who patiently walked me through putting it back together. So now I have a nice dual feed setup with his calibration, rebuilt...

    You must not be needing that GN1 exhaust anymore. I'll gladly take it off your hands :LOL:
