Rev Matching Issue

The primary input for this situation is going to come from the ABS computer.
Root cause is where your fix will lie.
Seems like this is a problem while turning, so looking into the Yaw Sensor data might be a good place to start. Compare the E8x to the E9x M data.
Or just outright unplugging the Yaw Sensor for a S&G test.

I'll bring this to the top. I believe we have a solution for the N52 MSV70 cars and MSV80 we need a beta tester...

Does anybody here have the ability to test this and provide feedback? Ideally a situation where you can be available to test several different calibration changes back to back if needed...

This is awesome news. I've started following Spec E90 and this has been brought up a couple times that I've seen. I'm not sure if they have a fix already in their spec tune but I would bet there are plenty of people that would be willing to help.

We have a client hitting the track this weekend to test these ported changes. We will update this at the beginning of next week.

Also looking for beta testers for both MSV70 and MSV80.x

This is awesome to hear. I'd be interested in hearing what the solution is because it needs fixing on n55 too :X
