    my tune check it out??

    hi guys this is my tune its probs the best one i got but i know it can be improved can someone help me for abit more power? i think its a bit sloppy

    im using a mbc but this map should work with stock ebcs at 20 psi

    im running 22 psi with mbc

    2002 ADM wrx sea level
    98 octane
    TTS td05 big 16g
    avo turbo inlet
    walbro 255 fuel pump
    stock injectors decaped
    STI TOP MOUNT INTERCOOLER off an 2007 adm sti W/spray
    oil catch can
    aps cai 65mm
    decatted uppipe
    3"TBE with catless dp
    turbo smart mbc set @ 22psi
    gfb 50/50 bov

    maf is rescaled aswell just down low using maf scailing tool i see no knock at all with learning view so i think im on the right track my afrs are still abit rich maybe in the 10.5 - 10.8 im waiting for a 3 port ebcs and then im going to run hybrid boost and re tune also might get a fmic later on :P but for now how can i make more power out of this map?

    i think that it can be improved on timing and afrs but help us out? if you want more info or more pics or logs i can get them for use

    your maf needs to be rescaled for ol fueling, fuel map needs to be smoothed out. what are you running for kcam? didn't you say you switched to an sd rom? pm me some logs if you want and ill help you out.

    Post your ROM on Romraider and then link to it here. Looking at a screen shot of two tables of a map isn't even close to being able to evaluate it.

    ok, that way we can scale the maf for ol fueling, it looks like you were trying to achieve leaner afr by leaning out the primary open loop table, that isn't the proper way to do it. Scale maf first so when you enter a target afr in the primary ol table you will be able to reach that target and that way your improper maf scaling wont throw your load off which your timing runs off of.

    ol maf scaling is done manually, and so can cl fueling. Like i said if you want i will rescale it for you, i'm not asking for money, just offering help.

    just looked at your log, theres a decent amount of knock after 4400rpm, iam drops to 8 :-o you are running too much timing for your setup. another thing is your boost creeps.
