    How do I slow down or half LTFT adjustments being made?

    I have wideband tuned my VE/MAF. I understand I can tweak the closed loop fueling stuff to fix this but I generally like how mine are currently set with how it drives so I was wondering, how else can I slow down the LTFT adjustments or perhaps just half it's adjustments it's making?

    Reason being is because I find that the LTFT's are 'removing' fueling a bit too much at times.... which then brings on knock. I know I can just turn off the LTFT's like alot of other tuners, but I don't want to.... it improves drivability if fuelling it's only marginally out.

    I attached my stock tune, if someone can point out how to slow down the LTFT adjustments. I only want it to pull back fueling or add it if really it's about +5 -5.... it's doing it within +2 or -2 for the most part and thats annoying.

    Can it be done? .... without doing proportional fueling adjustments just to 'force my hand' so-to-speak.

    So you're saying you want there to be a minimum LTFT requirement of closer to 5, and if you're within less than that you don't want the car to adjust at all? If we have access to that I don't know of it...I don't think we have access to it.

    Hmm there is something to tell it on most cars that max is 25-30% so maybe a scalar we don't have access to
