Yes, well I have a small problem :

1) Pectel told me : "This ECU shows as being on an AER developer. It is a very early unit for the T6 2000 range. Cost of changing the developer is 250UKP you will then need software. Software 315UKP."

2) The seller told me this ECU was used on Cosworth cars, so well I don't know how to trust. Is anyone able to tell, by the look of the serial number, if the ECU is locked or not ?

Serial number is 2022.

Thanks
