Ghettodyne Bin needed that doesnt run so rich.
 
the regular ghettodyne 450cc boost option bin runs my car sooo rich its insane.. anyone have one that like 10% less rich, i dont really know what numbers to punch in to ghettodyne to lean it out a little bit...

strange that it should run that rich. You got the sohc vtec right?

We had this discussion already, today. ::)

Drive to a place where you can drive straight and there is no one on the street. Start in a gear you can actually drive in, like, 2nd. Start at 1000rpm, and floor it. Pay attention to your A/F gauge (the reason for being on a street where there is no one). Flooring it, obviously, will put you in open loop where you will be strictly on your tables.

Anyway, do a run up until your rev limit noting where you're too rich.

Lean the numbers out about 3% until you get your desired effect. 3% you ask?

Yes, 3%. Say, at 3500rpm, at full boost, like 8psi, you're at 11ms. The equation I came up with is pulse_width - (pulse_width * .03) = new injector pulse width.

Yes, this is a PITA, but you know what, do it anyway. >:(
