1999 LS1 tach voltage
Im installing a fuelpump controller in my car and i have free usable wire from ECM which is suppose to go to tach. I dont need tach, so im planning to put tach wire to the puelpump controller. What kind of voltage tach wire is producing???
I need 0-5v to the controller.

Thanks WhiteBird for information. You confirmed my expectations. Guess i have to pick my voltage from TPS wire. I dont have my harness connected so i cant measure, but i presume throttle closed its 0 voltage and throttle open is 5V. Can someone confirm? Would be nice to know when i soon order my controller.

Oh man, that worrys me if i can get only 80% out of my controller that way.
You seem to have good knowledge about these electronics. Do you know where i can find good voltage to drive the controller and what kind of fuel controllers people are using here with success?
