engine speed not indicated using TP.

Post by mgbv6 »

I have a 3.4l V6 engine and ECM (ODB 1.5) from 1994 Firebird installed in a project car. Started up the engine but have no indication of engine speed indicated using TunerPro RT. The 24x crank signal is indicating engine RPM but the engine speed does not indicate anything (reads full scale all the time). All other indications appear normal. Where does the engine speed get it's signal from? The tach signal that comes from the coil pack goes directly to the tach. All my DTC are clear. Wondering if the lack of engine speed is affecting engine control.

this is the ADX I created/use, I don't know what you're running now, but this version shouldn't have any quirks to it.

installed your ADX that you sent me and it worked fine. Even the "engine run time" now works.
thanks for your help
