I had my XFI upgraded to 2.010 with ITC in April 2011. I finally got around to getting the XFI back in the car with some mechanical upgrades the first week of December 2011.
I wired my car for Turbo/Automatic/Transbrake control as presented in the diagram from FAST.
I have checked and double checked the wiring for switching and relay logic.
I am using a solid state relay for the transbrake.
I have the creep parameters set so that creep will not activate until boost and TPS parameters are met and I understand the operation because before I sent the box in for a 2.0 and ITC upgrade I was using the creep feature and it worked perfectly. What is different in my set-up (the wiring) now is that I set the staging up as shown in the Turbo/Automatic/Transbrake control diagram.
When the XFI box is powered "on", A-18 immediately becomes grounded and activates the transbrake (Pin 4 on the digital relay is wired to A-18). When power to the XFI is "off", A-18 is floating (neither +12v or ground).
I have convinced myself that the XFI box has an internal problem an probably needs to be sent back to FAST. Does anyone have any advice for me on this subject?
Another anomaly occurred that I am curious about with the new upgrade. I disconnect A-18, put the street tires on and went for a drive to test and and get some experience with the learning feature. When I reviewed the log I noticed that the learning was cutting on and off even though the parameters for learning had been met to keep it on. Has anyone else had experience with this issue?
