When I was still on the stock MAF my car idled pretty good. I switched to speed density and now my idle is all messed up. Most of the time I have to keep giving it gas or it will die. Also I can't seem to get SDairflowPerRev .25 and my combinedFT is off. I add deadtime and it doesn't seem to do anything. Please take a look at my log and give me suggestions. 1st log you can see my car starts fine then dies shortly after. I appreciate your help. Thanks
