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.

Cheers Simon, I will have a play in the morning!

 

i wouldnt of thought 0.1bar due to the cold weather was something to be worried about just enjoy it , but adjusting your power fc settings from andy's original map is

 

The problem with PFC and overboost is it oscillates, as it tries to achieve target.

Adjust the start duty as per JGM.

Cheers

Simon
