Fuel Injector Question
#5
the safc can tune the injectors +/- 50%, so it should be able to control 1000cc injectors, but the rest of the car isnt stock is it? so you can prolly go bigger than 1000cc. or to put it another way, if the cars modded, 680/720's are prolly just fine on the stock ecu

The real limiting item in any piggyback setup (including mine) is the stock AFM.
At 10PSI - WOT - 5K the AFM input will signal 100%.
At anything above that the S-AFC can only flat-line.
My 720's feed enough fuel to compensate under high boost.
The main job of the S-AFC is to push up the fuel between 2500 & 4000, before the secondaries come in.
It can also lean it back to something reasonable for daily driving fuel mileage.
I would only consider 1000cc injectors if I was planning a stand alone & FMIC in the future.
Or if you get them cheap..
