Well ran full closed loop to work toaday and the LFTS looks good. Only thing i don't like is when you go into boost takes few seconds's for tha a/f to drop.
I think there's a PE mode delay timer setting in there somewhere. Make sure that's set to zero.

There is a bug in the HPT 2Bar SD that will also delay PE when using the Boost PE table.

I found the value I was looking for. Make sure that B3608 is set to zero. Also, what is your throttle enable set at? Mine looks like this, worked pretty well for me.

When the truck was in open loop it would start dropping a/f after 95kpa because of b3647. Now that i went to full closed loop the truck doesn't start dropping intill 115kpa that when the P.E table kicks in. So how do get a/f to start droping at 95kpa? Here is my tune let me know what you think and if you want to see a log file let me know. Pt.net say the log file is to big.

OK this table I posted goes into B3616


In B3618 make sure your PE modifier is set to 11.5 AFR or .786 lambda all the way down.

There are actually less things to mess with when you are in closed loop.
