I'll start by saying thanks for any input that anyone gives to this thread.

I'm running an LY6 with a modified harness with the E38 ECM. I cannot get a tach signal from it? Everything is set correctly with HP tuners in the program and I think I have the correct pin from the ECM connected? The motor is in a 1992 Camaro, I'm using the factory tach, I've tried an aftermarket one as well.
Once again thanks for any help.

Did you set HP Tuners to read 'Crank' and the hi and low to 15? What Tachometer are you using?

Im using the stock tach (1992 camaro), I have hp tuners set to crank and 15. Im not sure which pin on the ecm I used I think its pin 49 on c1.

You're going to have to add 12 volts as well as a resistor(dont remember what size) to actually power the tach.
