    Default Advice on tune

    Hi Guys

    I've been slowly chipping away at my tune.... It's not my daily so i might only get it out once every month or 2.
    Today I drove my car to work and wanted to work on the bucking I'm getting on light throttle while going up the freeway.
    I have attached my 3 logs from today and my so far 2 changes of tune.
    Can I ask If i seem to be doing the right thing by modifying the throttle follower, it seems to be removing the light on throttle bucking.
    I also think I have missed a setting with turning on my o2 sensors with a closed loop mafless os, could anybody advise on this.
    Another thing I noticed today was it seems that my v2 is showing the afr at 13.7:1 but lamba on my logs is showing 1.0, have I set my commanded afr incorrectly or is my map setup incorrectly.

    Thanks for any advice

    Cheers Wade

    Hi Wade,

    I was out of town (again) so I could not look at your files.

    I'm back now (catching up), so I'll take a look after work.

    Sometimes whhen I see that, I start again with a stock file and add only the necessary changes (VE, MAF, injectors), nothing else.
