    3800 SC LTFT Reset / Learn

    Excuse me if this has been addressed before and I am sure the answer is quite simple but wanted to verify. For my 2000 Pontiac Grand Prix with the SC 3800 there are a couple buttons under the Special Function section. One is an "ON" button for "LTFT Reset". There is also an "ON" and "OFF" button for "LTFT Learn". How and when do I use these? For example... after a fueling adjustment do I click the reset ON ( which turns the button to green ) and also click the ON button for LTFT Learn ( which also turns that button green ) and then simply close the pop-up window? A little confused over what probably is such a simple procedure.

    I just click the normal trim reset after a fueling adjustment and let it do it's own thing. You could force the learn with those functions if you wanted I guess.
    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.

    Alright, I'll just click the LTFT Reset button to green and call it good.
    Thank you
