F9X M8 Competition 2020
Hi guys
I bought a M8 comp and had a carbahn stage 1 tune done (ECU flash). However, there was some issue with audio and roof light function that BMW service agreed to help fix. When they fixed it they default the program to 2023 version. I was wondering if I want to tune it again, do I follow the ECU flash as what Carbahn done before, or does it have to be a piggy back now cuz of the updated software. (exhaust sound changed I believe, due to the software update) |

The locked ECM are actual new hardware and software BMW switch too with Bosch. But yes you will need them to re flash now that you have had them update the version of software. Too my knowledge talking to a tuner he stated it does not lock the ECM with the older ECM's.
