Last year (2010) I discovered the Mini Cooper existed. Attached is a 5 - 6 page pdf of my experience installing "upgrades" on the R56. Eventually, the problem still remaining will be resolved, but to date, I still get an occasional "fatal" or limp mode cel, P2885. The fix will be a new ECU map with the Alta AccessPort, but so far it's low priority for the programmers, Cobb and Alta. Fortunately, the cel does not occur during high performance driving, only on my occasional lazy times when I don't down-shift for quick acceleration.
Let me emphasize that a Garrett should not be installed unless the ECU can be reprogrammed. I'm told that someone in the UK had a similar upgrade package, but without an Accessport. It was dismantled, I'm guessing because it was too costly or impractical to reprogram the ECU. Mine was on the dyno for 3 hours with two experts working on it. Results are impressive, and will be better when they figure out how to get the maximum JCW boost levels out of a non-JCW engine. I'm hoping to be their first customer for that upgrade.
More upgrades and another reason to not use a Garrett. Info was added to the previous pdf. For those that read it already, there were no changes to the original version, only additions at the end --- page 6.
