450cc afc hack isnt giveing cel
ok i was reading other peoples stuff on how to set their fuel input at each rpm range... i see that people that went over -35% threw a cel... Well i turned mine up and up and i got to -30% and nothing still happend.. i got a 95 civic dx with 14b turbo on it.... shouldnt it be doing something.. i dont have my a/f guage in ther yet so i dont know how tis running.. but i hear no pinging or anything so should i leave it or turn it down..?

-30% at what psi? Less than 9-10?
Run your ECU O2 input to the blue wire on your AFC, and you can monitor O2 volts under the sensor check screen. I can't stand an AF gauge... I'm like, "three bars green means precisely WHAT?" Not that a stock O2 is accurate, but there's a big difference in 0.7 and 0.9 volts, even with how regular O2 output skews with temperature. You want a precise reading, not "three bars" worth of a gay neon color. |

This is my air fuel meter. Each Led light has it's own pre-set ratio.

Stock O2 sensor reads one thing and one thing only - 14.7:1 at 450 mV. Beyond that, results fluctuate wildly depending on EGT readings, individual O2 sensor characteristics, when the last time you got laid was, whether or not it's a blue moon, and if the wind is blowing from a vaguely southwesterly direction.
13.2:1 AF on a turbo Honda is asking for trouble. The run of the mill D and B series likes 12.5:1 AF for maximum power and reliability, and some guys run down to 12.1:1 or so for peace of mind. You hear a lot of "get a wideband" stuff thrown around, and yeah - they are absolutely wonderful. What, you can't afford one? Man, I understand entirely... and you can tune just fine by reading your plugs. A wideband just keeps you from getting your hands dirty, and is very convenient. Keep the AF meter for a pass/fail indicator and you should be fine. |
