Hi guys,

Was wondering whether anybody would be able to help, installing my Procede 2.5 but my laptop is saying that it cannot find any USB drivers so I cannot communicate with the Procede.

Anybody know where I can find them?

Thanks!

I only have rev3 drivers, maybe they work? http://procedetuning.com/BMW/n54/dow...downloads.html

I don't believe rev 2.5 had native usb.
Had to use a serial to usb converter.

You are correct "We will also offer a service where we update your Rev2 to the new ignition/fuel control hardware (item 1 and 2) for around $40-50 including shipping. This Rev2.5 (?) will give you all the performance/tuning advantages of the Rev.3. The only thing you will not get is the extra i/o functionality and USB support."

Serial to USB cable. Driver comes with the cable.
