    fuel map advice needed (2.0 zetec on 750 gsxr inj.)

    Right, since i dont have time to actually play with the car i may as well get a heads up first.
    The map i currently have installed was kindly sent me by Ian Prior (fatbaldbloke) , its from a westfield 2.0 zetec
    running gsxr 600 38mm T/B's (mine are 750 42mm) and has been developed on a rolling road to a good map.

    on my car it gives excellent off load throttle responce, it revs like a chainsaw in neutral

    However ................ whilst it drives nice on light throttle it bogs down if i give it a bootfull and stinks of fuel .
    i have posted the map below and would be grateful for comments from our more experienced tuners.
    my own observations having compared to several other zetec maps is that the mid and upper numbers ARE POSSIBLY much higher on this map
    than the other maps IN COMPARISON to the low load site numbers.? ?
    please take a look and leave any advice or views you may have, it all helps me understand



    ps.
    our tps min / max position had similar numbers so table should line up in that respect.

    I'm no expert but the significant jump in numbers above 110 ring warning bells! Most of the maps i've played with 'generally' have top end numbers 2.5 - 3.5x the idle numbers ie. if 25 idle then 75 @ max. Yours seem to be 7-8x. Its almost like the map is for a turbo engine with bad MAP compensation! Can't be much more help i'm afraid!

    i too am no expert, i let dave do all my mapping, but over the years i have spent a fair while looking at map numbers.

    i agree with katana, fuel numbers at the top end seem to jump up too much.

    i also cant see why half throttle would have bigger fuel numbers at the bottom of the rev range than at the top
