    Started over with a stock tune

    I went ahead and just started over with a stock tune, I got it to idle really well when its warm but it still fluctuates when its warming up.

    Wow just took a look at the first file and if you are setup to use gasoline then you are way off! Are you running E85? The new tune has a completely different Fuel Stoich ratio. That needs to be set, not adjusted. It is determined by the fuel being used not how much fuel you need in the tune. Maybe you should start off from the stock tune and only adjust the tables you completely understand.

    I did start over with a factory calibration, I started out with E85 stoich value but I tested my fuel and it is E70 so I changed the stoich to match
