I was just wondering what the limits of the s-afc are? Whats the most they can control in injector size? I want to bore out my 550cc to 850cc at RC ENG. and i wanted to know if i will run into problems with this? Has anyone had 850s of higher with a S-AFC? I have stock ECU, s4, FCD, walbro 255 high pressure fuel pump, and RB 3" full exhuast... thanx

 

im going to e-mail APEXI to see what they say. I will post it as soon as i hear from them.

 

all 4 or just 2? you'd be fine with 2. all 4 might not be. plus it would be hard to idle those...

 

you can tune down injectors to -50%...so theoretically you should be able to run 1100cc injectors max, with no problems.

at least thats what ive read

 

well i am talking about secondarys only, i plan on keeping the primaries 550.

 

And do tell us!
