Hope this will be helpful for some of you who are looking to upload a flash tune to your E9X M3 - specifically one from BPM Sport.
Before you all yell at me, the tune that was loaded is a burble tune from BPM. I have a normal (non burble) Stage II engine tune from BPM, but I have developed a relationship with Mike Benvo and he sent me the burble tune to do a DIY install video on. I know the burble/flame tunes are very controversial. I personally prefer my non burble Stage II tune over the burble. But I will say that its been a fun experience playing with this burble tune and hearing how different the car can sound.
Either way, I hope this DIY is helpful to some of you who are looking for an instructional video.
