Hey can we real time tune while driving? Wanting to put a carputer in but was told cobalt/hhr ecu's can't do it with car on. If that's the case, piggy back 2nd ecu w tune installed n just figure a way to switch em? Ideas?

 

I think you are over complicating it. You can stop and flash to a different calibration anytime. The car ignition needs to be in the on position, but not running. (This applies to HPTuners)
