    Default 'tuner friend' told me to increase ve table by 10% temporarily-ve questions inside

    98 ls1- ms3 cam 237/242 .609 @112lsa longtubes a4

    he told me to increase ve tables by 10% across the board until i can get around to actually tuning it. my question is...when i am tuning, should i start from my stock tables or the 10%

    car is running pig rich at idle and i'm assuming during cruise considering my economy dropped from 29.5 to 19.4...same conditions both times...

    my ltfts are anywhere from +5 to +17...which means i am running lean and the pcm has to add fuel in order to acheive stoich correct?

    would i be better off returning ve tables to stock?

    i'm still trying to figure out how to make maps and whatnot so i can do the calc ve tune with narrowbands until my wb02 comes in...

    'stock'/starting tune:

    419PWM.tun

    tune thats in the car right now...its a horror i know
    ms3bas.tun

    Are you running with the MAF...?

    If you're running with the MAF then your VE table isn't responsible for those LTFT's (since VE will only kick in during transitions below 4000 rpm), so you can leave the VE table where it is.

    Take a look here at these tutorials:
    Calc.VET tutorial: A-New-Twist-on-CALC.-VE-Table..Computing-the-Entire-VE-Table.
    Calc.MAFT tutorial: Calculating-MAF-Airflow-From-VE-Table..CALC-VET-In-Reverse

    Those tutorials show how to make the maps you require.

    If you don't have a wideband, then filter out any data for which CALC.CL = 0 (or edit the calc_pids.txt file to make SELBEN use LTFTBEN only).
