Sequential Problems...
I have been having this problem with my sequential system since I bought my car, but thanks to the PFC, I might have found the cause... I just need some help interpreting the info.
When I get on it and the system makes the transition to the secondary, the boost will drop and build very slowly and will not recover until I get off the throttle or deaccelerate. Well, today while looking at the [Sensor/SW] display on the commander, I noticed the TCN (turbo control) switch comes on and "sticks" when the problem occurs. The only way to "unstick" it is to deaccelerate and then boost works again.
So my question is what is the TCN and what part of the system does it control? The fact that it "sticks" mean it's bad? Any help would be great.
