well i put the AFC and 450cc injectors in my car, but my car has been bogging when i shift gears and right when i step on the gas (at higher rpm). i have my afc programmed as:
1000-2000rpm: -40
2000-3000rpm: -38
3000-7000rpm: -35

i have that set for my high and low throttle.. i'm running a small td04h-15g turbo on a B18A engine.. at only 5 psi.. i'm getting full boost around 2800 rpm.. do you guys know how i might be able to tune this out.. and still run safely.
thanks

you should try leaning it out more....by the way are you running the check valves or straight with no bleeding off the map sensor?

wrXtian

i am not bleeding the map sensor..

What's your fuel psi? It sounds like it's dumping alot of fuel. If your map is hooked to before the TB try pluging the map the IM mani.

i have stock fuel pressure..

KoRE

same thing happened to me it was running to rich....so try turning down your fuel

wrXtian

what numbers do you think would be safe to run?? i see some pple run -40 all the way up to 4k rpm.. is that safe considering i get full boost at 2800?? i'm assuming they run a -40 w/ a t3/t4 which takes longer to get full boost w/

bogging is usually dut to over fueling.
i'm not going to give you any vafc number (to set it at) i'm only going to to tell you to get it on a dyno asap to tune your air/fuel ratio. guessing is not going to do anything for you (thats all your doing as of now)

The dyno and wideband will be your new friends. Try pulling out more fuel at idle

wrXtian

so i guess my car is running really rich..

Don't guess anything, we can all assume your running rich, but I advise you 100% to get your *** to a dyno asap and don't boost much until then... Its better then having a blown motor or breaking something else isen't it?
