    Default maft pro general questions

    Hey guys I can't seem to find exactly how I increase fuel and boost after putting new injectors in? What sections would I change?

    You would actually want to decrease the amount of fuel the ecu can see (if you installed bigger than stock injectors). Once you do that you can increase boost (slowly). What are your mods?

    People look for failure to justify their lack off action.

    Ct26 turbo drift motion 57mm, 2jz swap with 7m electronics. Still running the old 440 injectors from the 7m. Maft pro to tune it. Running about 12 lbs of boost. How would I adjust the injectors if I was going to say 550's or larger ones? I was told possibly the main scale although I'm unsure

    Mainscale is what your looking for. That's for gross adjustment across the board, then you'll have to tune with user tunes from there.

    User tunes? Like from other individuals? Or a program?

    And as far at main scale so let's say I installed 1000cc injectors, how would it be adjusted? Like a specific number. I'm really lost on that portion. I'm stuck with 440s currently and theyre awful.

    Somehow I hadn't found that guide yet. That helped tremendously
