If anyone running a PFC in their sequential turbo FD can tell me the function pattern they are seeing on the CCN (charge control)? I'm trying to figure out why I'm not getting more than 3-4psi under 4000 RPM, and I think my charge control valve is malfunctioning, given that I see a constant ON indicator, regardless of load or RPM.

Thanks in advance.

EDIT: After some searching, I discovered what I think I need to see here: http://www.autosportracetech.com/RX-...erOverview.htm. However, I'd still like to know how the values of the CCN and TCN sensors change on the PFC throughout the rev range, so if anyone has that information, I'd be much obliged.

there is some vague stuff in the FSM in the ECU pinout section. but that assumes the PFC operates that stuff in a similar fashion.

What I'm asking is for someone to run his FD while watching the Sensor/Switch Check function to see when the CCN and TCN actuate. My CCN is on constantly, and the TCN never clicks on at all. Given that the twin turbo control is largely vacuum-controlled, the PFC is essentially monitoring an issue it can't control. Knowing what the PFC should be seeing in a functioning setup will help me diagnose the problem.

thought to answer this as I did some searching and verified with my commander:

with base mapping the TCN indicator should turn on at around 5000 rpms and boost.

I came across this when looking for normal pfc operations as shown on the commander.
