Replacing the battery on ZO6 without loosing ECU memory, that s what I am aimming for.
I am thinking to connect the “REMOTE positive” of the ZO6 to another car to keep supplying voltage to the ECU then disconnect the ZO6 battery and replace it.
Is it safe? any recommendations or concerns?
Update: I did change the battery and it was totally fine to disconnect the better without any other source of electricity. The tuning did not get effected. I just needed to do the window index (programming) with is a 10 second process described in the car owner manual. I talk to an electrician who is specialized in corvettes he said he never had any problem with disconnecting a battery from a car and replacing it.
And from my simple DIY experience, I have taken a VW touareg battery out of it and re-installed it with no problem (car was switched off) what so ever and no programming was required either.BTW, taking the Zo6 battery out of the truck battery compartment was a pain, literally. Took me around 15 minutes. Battery has no handle so be creative. I have used a piece of thick wire, slided it under the battery and made me a handle to put it out. The frame around the battery compartment is poorly designed too. Work around it patiently. GOOD LUCK :whistle:
Thank you guys from your inputs.

Why not leave the vehicle running? Just don’t let the positive cable touch ground while you are doing it or have someone hold it out of the way while you swap batteries
because I could damage the alternator since it will be charging the battery and I am disconnecting it.
I have done it before (changing batteries while the car is running to avoid resting the ECU) and haven’t had any problems. But I dont want to risk the corvette
Any small 12V battery source, even a DC power supply with a 3-5 amp current output can be clip on to the battery cable terminals in parallel to maintain the on board electronics while the main battery is disconnected and replaced.
Also depending on the car circuit, a 12V solar panel plugged into a 12V outlet can workIsn’t there a thing that plugs into cigarette lighter to maintain ECU power while the battery is out?
