Mode 2 Write Error?

[GrannySShifting]

Not sure what this means, but tried to reflash a Camaro calibration to an 00 Silverado PCM both had the same hardware number so not sure why it wouldnt work. Kept popping up that error New Bitmap Image.jpg

Could even reflash the program I pulled out of it back into it?

IIRC This is because you are trying to flash a Different OSID and Vin which wont work.
I don't believe it would even work with a "write entire"

Same OS ID. I have all the Gen3 stuff, Ive flashed same hardware with Corvette or Fbody file etc. And that doesnt explain not being able to flash it with its OWN file I pulled from it?

And the F body Osid is different than the Sierra Osid according to your screen capture.

Hook up jumper cables.

[Bill@HPTuners]

this error usually indicates a battery or wiring issue.

has 0 to do with the os id.

OK thats even wierder then. Original file was written in the chassis, car was started everything worked as normal. The shop had another spare ECM they wanted me to flash the same stuff to as a backup spare, bolted it in and get this. Put the original in it, flashes fine starts fine?

didnt catch the nt typing fast I guess, doesnt read right if I could even that dont make sense LOL

OS on that screen capture is different because I was trying to write 3bar OS onto it. I later tried flashing the stock file that was in comp A into comp B (both end is 1344 OS or something) and that didnt work
