I've searched (here and on Innovate's forums), and while it sounds like I might be able to use the ECU tach signal (Pin #58)... I've seen other posts that talk about wrapping a wire around the negative of a coil/using "(Innovate's) RPM module".

The documentation states that you can either connect a tach signal or use an inductive clamp (not included w/ the LMA-3).

Anyone out there know for sure if using pin 58 works with the LMA-3?

 

Pin 58 works, that is how I have mine.

 

thanks
