*~*Calling all EFI and Turbo nerds, HELP!! running too rich on 450cc and 390cc w/ VAFC
I searched, but couldn't find anything specific to my problem.
set up:
B20Z (obdI), T3, Hack, -2 degrees @ dizzy.
Anyways, I was using the hack on my B20. I've noticed that I am always rich and in open loop. I've tried leaning it out via the AFC correction, and even used 390 cc injectors. I've even tried different ecu's just in case (p75 and p54).
The A/F meter is always on the rich side and it doesn't look like my car will go into closed loop. My EGTs are at 500-600 @ idle and 800-900 @ WOT. This is the case whether I am using 450s or 390s.
The only time my car behaves normal (at idle and cruising speeds) is with 275cc injectors (but there isn't enough fuel for boost).
So, whats the deally-yo?

I had the same problem with my DSM 450cc's...until I got a Hondata. The SAFC (even at low curve settings) didn't help much because my car was bogging like a *****. Invest in an engine management system and all your "rich" fuel problems will be resolved....Sell your VAFC on eBAY like I did. There's plenty of "H/A" owners that will take it off your hands.

I feel ya....I recommend Hondata to my friends....because when tuned properly...it is AMaZiNG how well it works!!....Opps...yeah, I am still using them w/ the low impedance Honda OEM resistor box of course.
