Ah.. ok. That's a speed limiter. The car will rev out to 7000RPM in the lower gears but stops the fun when vehicle speed is greater than 135mph. Removing or raising the speed limiter shouldn't involve more than intercepting the signal (freq, square wave, etc,.) and regenerating it differently. Done it before on many cars. I don't expect the BMW to be much different. It's just not something I like to get into on street cars. We don't even raise speed limits on our ECU flashes unless its for competition use, fwiw.
