Bench Tune 5.3?? Im just finishing up my frame off rebuild of my 76 vette. Swapping in an lm4 and t56. I have a friend who lives a few hours away that has hp tuners and was gonna give me the rest of his credits so he could tune my ECU. What do I need to bench tune? That way I could just take my ecu up to him. I have the complete wiring harness that speartech re did. What would be the easiest route?

Bench harnesses are for when the car isnt available. Well I have the entire engine harness. My harness has an OBDII connector the blue pcm connector and a check engine light.Its out of the car, so couldnt I just put an on/off switch between the power supply and the harness?

Thats kinda what I was thinking. I just didnt want to drive a few hours and find that it wouldnt work. So Ill just take my harness and ecu up. Thanks for the responses.
