How is the ECUFLASH working for you? Do you recommend this for your average tuner? Will you be able to get in to the parts of the ECU, eg.- that is Vin code changing, even add a key and the other 1/2 of the partitioned ECU?

As far as I know, the Vin code is not stored in the ECU, at least in the extracted Rom.. and the Immobilizer itself is what controls the keys, the code the immobilizer generates is matched to the ECU..
Eventually I can see the possibility of modifying the other attached devices that the MUT3 can modify.. But thats a ways off.
Tuning is partly art, partly common sense, and partly logic.. Anyone who has the patience and can take the time to do it right (don't rush into making drastic changes) and is willing to learn a little about these cars and how modifications affect ignition timing and fueling, can certainly do it.

THere are some cars that have their VIN# embedded in their ECU's, BMW is one I can think of offhand and shows up on my professional OBD-II Scantools.. My evo, and all the other "Pre-IX" Evo's definitely didn't have any Vin embedded.. I'm actually not surprised since OBD-II inspection testing probably would require that data now to avoid someone scamming the system with a workaround.
This is OT for this thread though.. I'll ask someone locally with an IX to take a look at it..

EDIT: found it. SAE J1979-2002, p.153. It appears to be optional to provide electronic access to the VIN.
