Ok so long story short I got another ecu.But for the life of me I still can get nefmoto to read it.This is what I have now.This is being done on the bench with immo disabled.Ecu is a me7.5 8e0919518ak stock ecu.

Validated FTDI device is in dumb mode.

Probably not a stock flash.

Bootmode flash a stock AK file with galletto

Already did.Then tried with nefmoto.Same thing.No change.The ecu I used I know was bone stock before i reflashed it with galletto.I cant communicate with the ecu even with vcds.Which leads me to believe either its bricked or stuck in bootmode??However when reading and writing in bootmode.No issues at all.Works fine.

Is it possible the ecu is stuck in bootmode???I read the flash with galletto.I DID NOT short pin 24 to ground.Just hooked up the ecu on the bench and read.Attached below.

That file is not stock

Code:

$ md5sum.exe bins/8E0909518AK-0003.bin 518AKnc.bin
de0521f258855661f27284d17dbc8907 *bins/8E0909518AK-0003.bin
bc80e7ef0e4cc918d7308be0edfd110f *518AKnc.bin
