Overboost with Power FC?
Hello,
AndyF mapped my car (and a fine job he did too) at a max of 1.25 bar. This was done in July iirc.
It has been running 1.25 bar and peaking at 1.28 ish but now is hitting 1.35 peak but also showing 1.33 at WOT even though its set at 1.25. I would put this down to the weather and the air temp, but why doesn't the PFC control, the boost to what it is set at?
What can I do to rectify this? Lower the boost on the PFC
Wayne.

PFC will boost cut at 0.25bar over the target..
the reduced air temp (density) causes the boost to increase
Knock the duty down slightly but keep the target the same.. try taking 2 off at a time.
