Sorry to revive an old thread, I am currently in this situation STi 2008 AUD - well similar.
I want to run a different ECU to the original - so that I can tune with RR.
Immobilizer issue - I live in the middle of the desert, Paraburdoo to be exact if anyone cares to see how in the desert!
Also about 1600kms from a dealership.
I find it strange that we can SH Boot into ECU's, Tune them, add more functions but can't get around this....
Is there any way I can utilize this 2nd ECU I have without having to drive/Truck my car 1600kms?
What does the dealer do that we can’t?
