    Hi Guys

    Finally managed to get back into my haltech and I'm looking at the maps, pics attached, I'm wondering what the fuel maps should look like? Is there a desired shape of the graph?
    I tweaked them a little to get the car to idle/free rev again after I put bigger injectors in. The fuel map is same across all the rpm ranges which I'm not sure is right. When holding rpm steady at say 2500, 3000, 3500 etc it misses so I know its not right yet.

    Ignition map just doesn't change within each range but I think I'll have to wait for the dyno to change them, any opinions on how much timing appreciated

    Get a wideband without it afr's are just a guess.
    If its breaking down its prob too lean which isn't good.
    Increase your fueling shouldn't be the same should be increased
    as load and rpm go up.

    looks like the ign maps are different zones so when u put them together they make sense, can't see much without having the program but any injector changes should be a injector data change if u change the fueling to suit an injector change then it won't be right, also need a WB for any load fueling changes like mentioned

    The innovate mtx-l is great. Easy to install and very user friendly

    You'll need extras to datalog though
