jason: that is a great read and great thread. one of the last missing links for an XB component that crosses over to an automotive component. thanks for your efforts.

Okay guys so I have done it all! Still when I unplug the servo the codes 21 both come up . Any ideas?

You may still need to set bits 3:0 of EDiag4 (Error Mask Byte 4) to mask off the AMC errors.
In ECMDroid, look under Error Mask -> Exhaust Valve Actuator

Thanks I'll see if that works.
ill Keep you posted!

I don't think ECMDroid has "Exhaust actuator" listed in the error mask section?

I know you can uncheck "enable exhaust valve" under ECM parameters and that should stop the code 21 as well.

@jmcelroy: can you post again the pictures with the Dorman 911-912 intake tract valve controller? I want to compare with the unit that i bought. In my case, it is not working - it's not making the open and close cycle with the combination of killswith on, throttle fully open and key on.
Thanks!

Thank you very much for this write-up. I just purchased a 2007 XB12X (my first Buell) and found that the module had a broken ear that holds the cable, and that someone had over-rotated the gear and damaged it.
