My wife's '07 335xi just started throwing 30FF. It's boosting OK but a little laggy; that basically eliminates the vacuum lines, which are pretty new anyway. The boost is not erratic, so I doubt it's the boost control solenoids. The turbos have 132K miles on them; their age and the symptoms point towards the turbos, but before I consider pulling that trigger, I need to do some logging.

I've long used MHD for logging on my '08 335xi, which has a stage 1+ tune. However, I can't use it to log my wife's car without buying a license. Before I spend the $75 on that, can anyone recommend free Android logging software?
I have no intention of putting a tune on my wife's car.

That $75 will pay for itself in the long run, well worth it in my opinion.

Hello,

I use the Torque Pro app (5$, maybe you can find a free APK somewhere) for other cars, it works good, but I never tested on my N54 since I have the MHD logging module.

It could work, but would probably need custom PIDs/custom offsets to read correct values.
