Questions

Are these files modified?

No. Every file is an original (stock) read of a GM C20 control unit, delivered exactly as read. If you need a modified file, order tuning below.

How do I find the right file?

Read the ECU with your tool and compare the hardware (HW) and software (SW) numbers — and the calibration when several files share one software number. The vehicle name alone is not enough: the identifiers decide.

How do I get the file?

Create an account on our file service, top up your balance and download the file straight away. Every original file costs €20.
