Big injectors ?

[wally]

What is the largest injector u can run with the powercommander and still have good a smooth idle , and at what fuel pressure.

I forgot to mention that i am using external fuel pump and regulator with large fuel rail for turbo system thanks

You can run any size if you reflash the ecu. I had 36# injestors in mine but I had to turn the fuel regulator down to 28psi, it still ran rich so I had the ecu reflashed and adjusted the regulator from there but a pcIII was still needed to make it run perfect @ part throttle. If you put a lot of ecu editing time in it, a power commander isn't needed with an fmu setup. This is what happened on my turbo bike. On a N/A bike it may ba totally different due to the need of the fuel to atomize better in the low rpm range. Turbo bikes can run way bigger injectors like 72#s if they use a map sensor, multi function hub, reflashed ecu, and a pcIII or just run a $$$tand alone system. Both systems will need a 1:1 regulator though.

Is any one using the AEM fic and if so what size injectors are they using

I had a fic on my gen 1 streetbike busa (now sold) , 550cc injectors
cold morning starts were a bit rich but otherwise no probs.
I did have it better with ecu editor but if i reset the injector size there i was not getting enough range on the fic (only goes to +99% dc)
Also have 565cc injectors on a 750 and its actually giving less probs using better injectors
