fuel injection problems on my first turbo civic
i have some bugs in my fuel system. NEED HELP
my set up:
apex vafc (settings for sensor in 14 and out 6)
gm 3 bar map
rc 550 cc injectors low impedence
the problem is that it struggles to stay on at idle at times. i will try to adjust with afc at idle and it will run fine, but then after a while it will run like crap. It will start to sputter and then die and it will not restart until I adjust the afc. the adjustments to afc are -10 at 1000 rpm and it will work for a while, but then i have to set it back to zero or it shuts off or sounds like crap
another problem is that it hesitates when i step on gas should i lean it out with the afc because of the big injectors.
any suggestions

you will not be able to make it run well. your car is dumping fuel on tip in for 240cc injectors. it is going to hesitate becuase of this unless you upgrade your ECU.

Holy **** batman thats a lot of fuel. How much psi are you running. Oh, and for the idle, you are dumping mad amount of fuel in there no wonder it keeps stalling on ya. Just thinkg about it most ppl run 450cc injectors at -35 or so for the idle. Compare that to your 550cc injectors and running -10. your running your car at idle on a 495cc injector ( subtract the 10% ) 495cc vs 240cc ....hmmm......like i said b4, holy **** batman.
BTW- check your sensor settings again, there is a thread on here about it but i'm almost sure it's suppose to be 14 in and 14 out for the GM map sensor. 6 in and 6 out for the honda map sensor.

Re: fuel injection problems on my first turbo civic (Del_Slowest)
i adjusted the afc like crazy it still won't work
i went up to -50 to idle correctly and adjusted the timing as well.
it still wouldn't work i think i need to buy hondata now.
it cost so much though please help me save my money $700
