in hp tuners scanner, is there a parameter to select that shows if the ecm goes into closed/open loop at all? i'll revert the PE enable back up to what they were. in the scan how do u know it went into PE? also whats wrong with my PE EQ values? too lean? i calculated it to hit 12.4AFR commanded

Just because you command it doesn't mean that is what you will get. You need to leave the car alone and start reading information on how to tune.

i was only stating what i put in there and for anyone to know. im more concerned about the DTC code and fixing that then i can go about tuning the AFR. i know theres more tables that affect the commanded AFR than the one table alone. thanks for the input though.

Tune the car and the codes will look after themselves. You are going about things the wrong way. Pick up a book and start reading........

I would suggest that you not go WOT until you tune that thing unless you wanna buy a new motor. Also clear all the stuff out of that scanner table that isn't needed. You don't even have the bank 2 O2 in there.

hes not gonna hurt the motor from being lean naturally aspirated....

but yes.. please remove most of that stuff from the scanner.. get down to 24 PID Bytes or less..
and like I said... get a wideband on that thing, and throw some more fuel at it at WOT..


also.. please check Fuel pressure at WOT....might just be losing pressure at WOT..

Currently have the b2s2 turned off as its only emission purpose only. I'm planning on getting headers tomorrow so I can install a wideband bung hole. Was thinking about tuning OL and tune also with AFC mini fuel controller on the fly.

I'm talking about bank 2 sensor 1 that controls the right bank fueling
