E35a vs E35B computer

[jeeper]

I know the E35A is for LLY and LBZ and the E35B is for LMM but I'm wondering if the E35B could be flashed with a E35A OS and operate a LBZ engine? And If it can, is it able to be done with EFI Live or does it require GM tools like TIS2web or something to do it?

It is not possible to exchange A to B or B to A, they are internally different designs.

Thanks.

Actually tried it couple times just to see what happened. Bricks at about 90% load mark.
Good news, ya can recover with GM MID at very worse, accidents do happen.
