How to recover ECU if flash fails
MaptunerX has a recovery option built in, so you can always recover an ECU if a flash fails.
If a flash fails then you can try to download the same file again or the stock file.
If the flash has failed then the ECU needs to be powered manually, this is done by pressing the start
button. It needs to be pressed down the whole time when doing the recovery (Fig. 20 & 21)!
