Hi i'm new so you may have to explain things a bit more for me. sorry in advance.


I'm going to be running a GSXR 750 ITBs on a 22re engine. These throttle bodies have one injector before, and one injector after the throttle plate. I figure cant run the injectors before the plate at idle because i'd have puddles of fuel at the plates. I could run the at a higher RPM though right?

How would I set up the system to run correctly? Would I need two systems (thus two maps), or could i set up two non similar banks, with one bank to only kick in at a specified rpm range?

I would use one map for the primary injectors and one for the secondary injectors, and make the ones at the plates the primary injectors. This "puddle of fuel" is actually not a bad thing - the air flow picks up speed as it whips around the throttle plates, and this shears the puddle of fuel off the throttle plate and vaporizes it. Use this to your advantage by making these the injectors that fuel the engine at idle.
