Hi,
Have an 09 Challenger, has an Edelbrock E-Force variant of the Eaton TVS-2300 blower, has a pulley setup making about 9psi of boost.
I've tuned VE, and am getting plenty of fuel shown on the wideband for various PR's both part throttle and under WOT... so now trying to tune WOT, and running into some issues under WOT.
Going WOT in second gear, the car comes up on boost starts to develop torque and then starts sputtering, I can see in the log that the ECU is pulling timing.
The tune I have currently is based on one that was developed for me by a CMR tuner, that read with HPTuners, and then revised for larger injectors. Basically other than injectors DW 72lbs, and VE table data, I've made no changes. Car is stock 6.1, catless, has new NGK 2315's gapped at .035.
I'm attaching two logs, first is a WOT 2nd gear pull which I abort when I notice is start falling on its face, and the second log is basically the same but its a 3rd gear pull, which I also aborted.
I should also add that I have some logs of the same tune where it just simply hauls ass through the entire pull... and I can't really see any reason for the difference in behavior, example log is the last file attached.
Tune file for the ECU as well as the TCM are included.
Mainly looking to understand where the misfire is coming from and how to get rid of it.
Thanks!
