Tune Help

[Peyton]

Have a 2020 mk5 Supra ECU has been bench unlocked by a90 shop got a VSRF catless down pipe and HKS charge pipe. Recently got a flash tune from bm3 with WiFi adapter and downloaded stock tune and stage 2 tune. When went to flash in diagnostic mode around 3% I had an error at drivetrain malfunction and it keeps having error after that car won’t start. And I’ve msgd tuners and emailed bm3 to no response if anyone knows how to fix this please help me out. Had car doors shut seatbelt on and lights off as well while flashing but no battery maintainer.

I don't have to go into Diagnostic mode when flashing BM3.

Try turning power on, connect Wi-Fi adapter and flash.

If not in diagnostic mode it won’t connect car to my WiFi adapter

My tuner had this issue happen with an m340i. What he did was flash the stock tune back and locked the ecu so it basically had to get bench unlocked again. After that, it was fine

I use my laptop and Enet cable and it doesn't need diagnostic mode. Guess the adapter is different?
