    Question Am I crazy? SD Tuning Help

    I'm trying to tune the VE from the cam swap and currently I don't have 2nd so I've stuck to 3rd gear to hit cells for VE. I'm seeing some 25% STFT's, am I doing something wrong or is my fueling really way off?

    The .hpt labeled before is what I started with. I know it looks rough, but I'm working on it. The first log file is from the "before" tune. I copied and pasted special mult by %, and then got the "after" tune. The last log shows my trims after the last change.
    I'm purposely not entering PE right now just to make sure everything is fine.

    Sorry if I'm confusing lol. Thanks in advance for looking at the files.

    Jake.

    Also I have a feeling your maf is not failing because your telling it everything is fine by setting your dtc's to no error reported for your maf codes.

    It doesn't have to be perfect, it just needs to be done in two weeks...

    Ah, that makes a lot of sense now Bill. I think the reason I set it to no error reported is because I went into limp mode (aka no start mode with P0068) in the middle of an intersection one day. I'll see about making it MIL on first error and seeing if that helps. I'm gonna go mess with it now haha.

    Thanks,

    Jake

    Bill, you're the man. I set it to MIL on first error and went about my business. Also, I pulled up my VE from before the cam and modded it through the logs.

    Tomorrow I'm going to hookup my buddy's LM1 to the truck and see where I'm at. BTW, about how long does it take to process the upgrade to Pro? I'll be shipping overnight too.

    Anyways, thanks so much for the pointers . Here's the files/logs.
