Grockle,

Thanks for the advice.

I have actually tried everything you have suggested. I am running Windows 10 on a new MS Surface Pro 4. I am using the mini USB cable that came with my GoPro.

When I loaded the S&S software I never received a message asking me if I wanted to load the drivers anyway. I connected to the ECU to the USB, powered on the ignition, and nothing happened. The drivers didn't load. I tried it multiple times, including uninstalling ProTune II, and reinstalling it. Rebooting, etc. I even tried watching this video, but I still couldn't get the connection to work. I gave up after about 45 mins of trying.

I am feeling frustrated not knowing what is causing my check engine light. It doesn't seem like anything is wrong, but it would be good to know why the light is on.

Also, I noticed that my engine break-in period is taking rather long! I have about 8 hours of use with 185 miles on the odometer, and my rev limiter still is kicking in around 4600rpm. When does the rev limiter go up??? It's hard to find nice days to drive the M3W, but I am anxious to get the rev limiter off!

Thanks guys!

Ive tried Windows 7, Windows 10 and even a Mac (running a hypervisor) in all cases, once the ECM is powered and recognised the drivers load.

Rebooting may be required once the drivers are loaded. Try a different USB lead, make sure ignition is on
