i think i corrupted my nvram the light comes on when ignition is on but goes out instantly when i turn ignition off

the car runs but the light go out instant

is the CEL on ? does sound like corrupted.

the light on nvram is on when i turn ignition off it goes out straight away engine light dont come on could be blown

the dash on tuner pro goes all over the place lol would that be cause its corrupt

well if youcan connect to it for logging and if the flash tool can connect to it its probably not corrupt.

see if you can write a standard bin file to it..... if so then try and put your cal over the top of that ?

i got the bin off it now all the monitors now work weird just wouldnt find the hardware before but light still goes off instant oh well

so i just leave ignition on when i do that dont have car running

is it wired up in a converison or something? B1 and C16 are memory wires, if one of these are switched with ignition instead of being on all the time, it could be the reason the light goes out straight away.

its a vp with a ecotec the wiring is vp engine loom nothing elese touched
