Initial Dyno of Cobb Accessport Tune for the BMW N54

Of course, but this is more just future discussion on how the Cobb could be used for people who have custom built motor setups.

My AP arrived and, as I expected, the xi is not yet supported. ECU data is on it's way to Cobb.
Gary,
Any guesses for when xi support will be released?
Thx,
Dan

The AccessPORT should install on your Canadian model without issue. We are nearly complete with our XI testing and should be announcing XI support very soon.

Thanks,

We just saw a vid of an xi accessport car running so how could it not be supported?

different years/different firmware/ews

Could be... Mine's a 2009.
The AP readout said it was identifying vehicle, then said it wasn't supported, and then offered to record ECU data.

How does this tune read performance numbers?
Does it have built in GPS? Accelerometers? How acurate is the data it puts out?

That's weird, so which year xi's are supported?
