hi i have a cuestion if the rtek 2.0 adjust the injectors in a 15% +/ - and they said that it can control 720cc or biger injectors why all the people arrownd here said that the afc cant control 800cc?? the afc adjust in 50% +/-

I whant to know if its possible to run 1600cc sec with afc

now im runing 12aT 800cc sec on my s4 TII with stock ecu and fpr without problems and I have other fc that are runing 4 gslse 680cc injectors with stock ecu
and it run 12.3 @120mph 17psi boost here in Puerto Rico

you only need to trick the spring on the flap of the flow meter to close it a litle bit to have a good idle

but returning to the cuestion anyone know if the afc can handle 1600cc?

I seasched all the site

 

the reason why the afc cant control bigger size injector is that it fools the stock ecu only..so say the stock 550cc is upgrade to 750/800cc thats almost 25% more fuel. u then set the afc to -25% or so and the stock ecu will see the 750/800 as 550cc..not an accurate but that the concept..

also because of the way the stock ecu run the inject its hard to set up the afc correctly.

i've heard that the stock ecu runs the pri inject at 50% when the sec. injector kicks in..so theres no way to run the pri. injector at 75-80% at all.. the rtek can be program to run the pri inj at 75-80% so with just the ecu reprogram u gain about 15-20% more fuel from the pri inj when the sec. inj kicks in.

if anyone else can correct me or help out with this post plz do..

gao

 

damm..lol..didnt check the og post..i'm hella late on this topic
