2015 Challenger 5.7 TSP BFD Cam, VVT locked, Valve Springs, MDS Delete need help

[[email protected]]

Hello Everyone,

I am new to tuning this new-fangled electronic stuff. I had a head gasket leak in cylinder 7 so why not just upgrade right? I installed the TSP BFD cam, new valve springs matched to the cam, MDS delete, scat pack airbox, otherwise the rest is normal. It is the automatic, I have not done a torque converter yet. I have turned off the NN and went with the VE tables. I have played around with the tune, and went through the tables as I have seen suggested. When I put the car in drive sometimes it goes fine then other times it just stalls. When I do have it where I can drive it, the car will suddenly stall when turning into the driveway or a turn. I am including the scanner results and the tune with this. I hope someone can help me get this figured out.

try this and you need to log air-charge and pressure ratio and dial in your VE and get a wideband to tune WOT

Thank you, I will give it a try and log those. I was figuring I needed a wideband, just have to get one ordered.

Thank you again,

Jeremy

I wouldn't worry about a wideband until you get it running right at part throttle.

A VE table should never be higher at 600 RPM than it is at 800 or 1000 RPM.

This is more like what it should look like.

yes i agree on the wide band and i know VE should not look like that i just smooth the base VE map out a bit that is why i said he should dial it in im pretty new in tuning so dont have VE tables that would be close, so i help with what i can

Dial in your VE at idle,

I've dropped it by 20 for the car am working on now which is running BTR stage 2 VVT cam.

Go to the torque model and then to friction loss table and bump up the figure to 5 as a start up where the rpm drops,, like from 600-1000 rpm where the car struggles usually.
