Iv'e had the RMW tune installed on my 09' Mcs since April 12th (6 weeks) and the idle rev fluctuations seem to be getting worse... might try an ALTA map or remove the tune all together. Don't know what this means long term.

 

It doesn't mean anything, it's just annoying. It's not hurting the car. RMW should be able to help you out with a new tune.

 

Email Jan. Let him know your problem and he will send up an updated tune.

 

So, how's the reliability been on the car now that you've had it a couple of years? Have you needed to go to Mini for service? If so, how did that go?
