I've already got an SD Tune which was developed from following the AutoVE tuning tutorial. The LTFTs fell within the -4 to +4 range, so I was going to go through the tuning tutorial again using the current SD tune as a starter. I followed the tutorial, modifying the settings in the current SD tune, then flashed the tun into the truck. The truck wouldn't stay at idle even when giving it gas. There was the strong smell of gas, so I increased the initial B0101 table by 5% over instead of the recommended 15%, flashed the tune, same problem, truck wouldnt stay idled after cranking and there was the strong smell of gas again. I'm wondering, does this tuning tutorial have to start with a "stock" tune as opposed to a tune which has already been through the VE tuning process? I've gone over the settings about 5 times and everything seems to be set correctly in the SDAutoTune.tun file. I cant figure out why this is happening again. I went through all my notes for other values to modify in the tune and made those changes (increase C6101 by 100%, set C2903, C2904 and C2906 to zero,zero out B5001), but truck still wont idle. Have I left out a modification?
