factory gauges with ls1 pcm anyone?
i just finished up my swap tonight fired it up and everything works pretty good. still a few things to do.
but i notice my gauges were off. is anyone done the swap and used there factory gauges and done the conversions using efilive, hptuner, ls1edit, etc?
if so let me know what you did to achieve the correct gauge readings.
thanks

Speedometer:
- Electronically driven speedometer (90+ Camaro, 87+ Firebird)
Electronically driven speedometer can be reused on the LS1 swap. You will need to reprogram the LS1 computer so it will output the proper signal to the stock gauge cluster. Another option is to purchase a signal conversion box like the ones from the dealers links below to convert the signal outputted by the VSS (vehicle speed sensor) into the proper signal for the stock speedometer.

i dont think you understand my question. what i am asking is that. what is the conversion, equation anwser to use on efilive or any other kind of tuning software. not how do you do it. i already know what you have to do. all my other gauges already work properly. and my tach is already calibrated.

Well from what I understand you don't need to do anything but hook up the speedo to get it to work. I installed a Autometer gauge so this info is all from a third party and not first hand.

You will have to have the PCM programmed with the gear/tire combo for it to read correctly, but output pulses are like GMTech said, 4000 ppm, just hook up the VSS output wire from the PCM to the speedo input where the buffer box is on the dash harness, which is under the passenger side of the dash harness. If the guy programming the PCM isn't using a program that a simple speedo calibration on it, I would get it back and probably send it to someone else so it would be right. A lot of guys where I live use Bryan at PCM4Less and love the work he does.
