Hey guys so I have searched and found the thread on how to maf scaling but heres the thing. Sounds like this how to assumes your injectors are either stock or already scaled and dialed in as you use your fuel trims to adjust the maf scaling. Here is my dilemma.

I just did a major upgrade I went from NA to FI, swapped in 440cc injectors where my stockers where only 240 (pathetic I know lol), and port matched my intake ports to my head. I am having trouble scaling my injectors I am having to scale them at 336 and latencys over 5 From what I have read most injectors are scaled around 12% below rated flow correct? This would put me at 387 and I see most posts saying latencys are around like .8, 1.2, etc. I need some suggestions on how to scale these together or how I would scale one then the other and which one as it seems they are both scaled according to fuel trims.

Thank you for your time and help

 

ok what you should do is use the wrx latencys... (check a wrx forum) start at 440 and then work you way down... till you get it in a good "zone" the mess with the maf scaling,....

 

Ok I was thinking about doing something like that, Maybe I will try that. Thanks for the reply
