Doing preliminary testing for future (about a week) fuel controller (VAFC). I have checked the plugs, and they stay pretty brown/blackish when drive casual, and get a little white when run hard. I'm also doing some duty cycle testing on the injectors to maybe see if I need to upgrade will all the following mods.

Can anyone enlighten me on exactly how much richer the fuel map is on this computer (skunk2 P72 obd1). I am running the ECU, with stock injectors, ported stock IM, Rcams, 68mm TB, FPR (set @46psi), and a P&P head (JG pro-series), bored (.010)Stock compression bottom end. Iceman kit (street), full exhaust with random tech cat.

Problems... ungodly rich at idle. A/F meter constanly 9 of 10 lights. EGT at idle never even shows above 300dgrC.

Crusing... 9 of 10 lights a/f, egt around 550-600dgrC.

WOT in VTEC... around 7K rpms, 9 of 10 lights a/f, egt climbs to about 650dgrC. black smoke. Not blue, or white.

Was wondering if someone could give me an idea of how much richer the fuel map is. And if possible, if it's consistant across the complete rev range or if it is gradually more as increase in RPM and extremely richer in VTEC.

Thank you in advance for any possible help.

 

yup, that's a given with the skunk/mugen progggy.
It runs rich (black smoke), that's one of the main reasons this program is a power maker. A VAFC/SFC fuel/vtec controller is highly recommended to fine tune the fuel dumpage, while on a dyno.
