    2000 Ls1 - Having issues tuning Fuel Injector Connection 127 lb bosch Injectors

    I am trying to lean out my idle. I lower the values on my VE tables by 5 and 10% but it doesn't seem to make much of a change if any.

    It seems that the minimum injector pulse won't go below 2.3-2.5. I believe I have entered all the injector data correctly.

    My car is a 2000 firebird w/ a ly6 turbo motor without the turbo.

    I have read threads where people lower their transient min fuel miligrams and short pulse adder but those are all old threads where people mention that injector data wasn't always available.

    Any ideas? Thanks

    Try lowering the min fuel milligrams from .041 down to .020.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    It looks like it's working. Still seems a little weird but much closer. Thanks you.
