i have a B16A with a greddy turbo kit and i just installed a vafc im trying to tune the damm thing but i have no clue where to start off on. and i got a set of injectors from a friend i have no clue what the hell they are but they are from RC engineering anyone know how i can tell what the flow rate are on them so i can tune the damm thing. btw im running about 6 psi on the kit.

thanks for your help!

every engine setup is different. even if someone has the exact same setup as you, their settings necesarily wouldnt work with your setup.

I found this on HT it may help you.

I have all of my correction points 600 rpm apart starting at 1000. I start with -38% correction at 1000 and work up to -29% at about 3800 and keep it there the rest of the rpm band, this is for the narrow throttle. My wide throttle starts at -22% at 1000 and works up to -5% at about 3800 and stays the rest of the rpm band. My throttle postions are lo 10%, hi 65%. I'm running about 8.5-9 psi of boost and its running great. I will be wide band dynoing this set-up next month so I can fine tune it, but so far so good. Keep in mind that your setting will require less correction since you have smaller injectors, but this should give you an idea. You could probably get away without using the v-afc and just running lower fuel pressure and letting the ecu handle the rest. That was what I was going to do but I got a good deal on the 370s. Anyway, good luck.

The injector should have their cc on them somewhere. Probably stamped on them like dsm's.
