Just removed dod and replaced cam with stage 2 added long tube headers. Now it will not idle smooth and the fuel trim is crazy how can i make these adjustments?
and the o2's is still making things run rich.
Trying to figure out how to post my tune. Can anyone tell how to do that?

You will need to setup tune to use MAF only and/or VVE only (Speed Density). There are a few videos on youtube on how to do it. Goatropegarage has some. Maf is easiest/quickest, so start with that. This is how I do it. There are probably better ways but I've had good success with this. Set up graphs in the scanner application that resemble your maf and/or vve tables that are in your tune. Use your stft+ltft data to get idle and part throttle fueling dialed in. When creating the graph the stft+ltft parameter is in under the math section.. You will need a wideband to do full throttle fueling for those 2 tables.Originally Posted by Mdennis
