Long story short i bricked my ecu and galletto cannot even flash it in bootmode. So While im waiting on an eeprom programmer and solder station to arrive i borrow a tuned ecm from a friend and installed it in my car it started and died so i adapted the immobilizer with the VAS 5054 and the immobilizer light went off now the engine cranks but never starts. I looked in measured values and the injectors are not firing only way i got it to run is if i flashed it to stock file.  I even flashed the tuned file back to his ecu to see if would work now but still same thing. Question is there some sort of immbolizer in the tune or a "firewall" some tuner could have built into the tune to only run on a certain vin?

Which eeprom do youback up? The 95040 or the 29f800bb? I always back up the flash chip but never needed to do the immo info.

Tuned ECU was likely locked to a specific VIN/IMMOID that was stored in the eeprom(8 pin device) as mentioned previously. The bricked ECU should always be able to be restored via boot mode no matter the eeprom contents. There is a resistor on the bottom of the PCB you should remove which will most likely allow you to program via boot mode again.

There are some that will never enter boot mode without removing this resistor. It is shown in the picture here:

We have had to do it with many ME7.1.1 ECUs, it has solved the problem 100% of the time.

My R32 ecu also really likes a 1k ohm in the ground cable for boot mode.
