Writing to NVRAM Troubles

Post by gmh265 »

Hey Guys,

I have been trying to get TP working with my VS V8 Auto, (previously using 12P on another vehicle with no issues, however I did not write the OSE bin to the nvram myself) and I am getting verification errors when I try and burn the bin file. (see attached screen grab) I have two NVRAM's and they both do the same thing. I installed it in the car anyway and the engine runs and I can connect to the ecu however the check engine light is on and I can not connect with the flashtool.

any ideas? is my burner a piece of crap? (pocket programmer)

cheers,

Prob first try checking all pins are ok and give the NVRAM a wiggle in the ZIF socket as sometimes when they get older the contacts can get dirty.

Can also try writing another bin (try the 12P stacked one and write with 0 offset). Does every burn give the same address errors? And same address on both NVRAMs?
