Formula for moving AFR 1 point
I know its 8.6% for 450s, but what formula gets you that percentage?
Wanting to know for 550cc injectors. In uberdata 1.7 if that matters. Thanks |
Re: Formula for moving AFR 1 point
A percentage is a percentage...take whatever fuel value you want to change and do the ~8% thing no matter which injectors you are using.

Re: Formula for moving AFR 1 point
It's not '8.6 for 450s' or ~8% for one point. :P
Depending on what point you're moving, it's all different.. Look at it like this.. from 1 to 2 is 50%.. from 2 to 3 is 33%.. 3 to 4 is 25%, they are all 'one point' but the amoutn is different.. Get my drift? So if you're going 10 to 11.. it's 9%.. 11 to 12 is 8.3%.. 12 to 13 is 7.7%.. 13 to 14 is 7.1% 14 to 15 is 6.6%.. Bottom line.. there is no 'blanket' percent to move on AFR point. Also, Chris is right about the injector size. It doesn't matter. A percentage is a percentage. 240s.. 450s.. 1600s.. its all the same. |
