E46 M3 Shooting Flames from Exhaust Backfire Tune
Here is video footage of an E46 M3 running B-Spec tune and our Stage 3 Buildjournal Exhaust Backfire Tune (BJEBT) flashed via ECUWorx’s MSS5X Binary Modification Tool. You can hear the exhaust begin to pop on throttle lift and occasional flames while the car continues to decelerate. If your car meets the requirements for the tune, head over to our official page for more information including download/install instructions.
