As far as I know all Ecutek reflashed ECUs are locked after 2006.
Ecutek has said that any of their tuners will return the ECU to stock for free. That was the last I heard, but that was ~6 months ago.
I would give KTR a quick call and see what they say, with KTR being an Ecutek dealer they are the ones that know for sure.
Thanks. They're the ones that sold me the EcuTek license and did my tune in the first place, but I thought they were out of the tuning business after Franz left, and his replacement didn't last all that long. I was thinking about trying to get a hold of Franz independently and seeing if he could flash it back to stock for me so that I can get an OpenSource tune done on it.
