Closed loop wastegate control - service interval

Post by sicup2 »

Hi all,

I'm trying to bring the boost control on my rally car away from the dark ages of open loop control and am getting my head round the closed loop options quite well, but wonder why there is no (or if there is I cannot see it) service interval table like there is for closed loop fuel control.

Depending on the intake manifold size, pipe routing, turbo etc, there will always be a delay between a change of wastegate duty and the corresponding increase/decease in MAP but is this perhaps not important due to the relatively slow changes in MAP compared to fueling??

Thoughts anyone?
