Re: help me with my tune before dyno this spring

A log at idle isn't going to tell much. Idle is the area of a tune that can vary the most from one car or setup to the next. Your O2 is wanting to add a lot of fuel at idle though, but fixing that could be as simple as a little change to the dead time. As Carl said though, if you have 1000cc injs on pump gas, then the global should a bit closer to -55%. And you would never have that much timing added to pump gas, it's rare to have much timing added to a pump gas tune, unless you aren't running very much boost.

If you are running DSMLink 2.5, I would use the older software. I like it better for the old stuff, except the new software has the reset fuel trims button that comes in handy when you are starting out trying to get things close.
