OK so here's the story that im hoping one of you tuning guru's can help with...
My friends Mk5 GTI recently had its ECU replaced because it failed out of the blue. $3,500 later the car is back on the road again thankfully. The car was tuned (Viezu) at the time of the ECU failure and used one of their rebranded Alientech controllers to upload the tune.
When the original ECU died, the car had the aftermarket tune on the car, hence the Alientech controller is locked to the old ECU.
New ECU was fitted by VW, loaded with a stock 147kw tune. The Alientech controller is now useless as its still locked to the old ECU.
For anyone who doesn't know - these Alientech controllers lock to the vehicle's ECU once an aftermarket tune is uploaded to the car. If the original tune is flashed back on then the controllers can be unlocked, reset and used on another vehicle (similar in a way to the Bluefin units).
Question: Is it ok/safe to temporarily remove the new ECU, refit the original ECU (which my friend still has) and attempt to flash that ECU back to stock with the Alientech controller? Providing the original ECU still actually works to some degree, this should allow the Alientech controller to be reset.
I have also emailed Alientech in Italy (yesterday) to ask about possible ways to reset the controller, but have yet to yet a response from them.
My friends car is now tuned once more (with a different tuning company and new controller) but would like to know if we can re-coup some of the money by resetting this controller and selling it.
Any advice would be appreciated.
