Cant get closed loop boost control to work

Post by BLR »

I got the duty tables dialed in with open loop and transferred them into my target tables for open loop, but at WOT it doesn't create any boost over spring pressure.
It is a Flex fuel tune so there is probably some simple setting I overlooked, but I cant get it to work.

Thanks in advance,
Brian

I'm still having trouble!

Here is another datalog that shows me peddling it.
As you can see the duty cycle starts to come up until the throttle get over about 90% throttle, then it drops to zero. when I lifted and the TPS went below 90% the duty cycle came right back until I floored it again, then back to zero again!

I'm stumped!
