I've managed to fix nearly every issue except this low load/ low rpm bucking. The only thing that seems to consistently help is running richer. I increased the VE table values in the cells that correspond to city driving (25-40mph) and that helped a lot. I wanted others to look at my file and make sure I'm on the right track.
The other issue I have a question about is cold starts. The closer the engine is to operating temp, the faster it will start. From 100-185* I turn the key for a split second and the engine is running. When it's cold it has to crank for a few seconds. What table do I need to change and how do I change it?
The attachments are: my current tune; 2101566VE is driving on the freeway with MAF disabled (I have since reduced the 50-100kpa cells in the 1600 and 2000rpm columns); 21015MAF is driving on the freeway with VE disabled; 21715eburg is a drive I did last night with everything enabled. It starts with city driving and a WOT pull, then I'm on the freeway for the rest of it.
