Help!!! with O2 Sensors & Fuel Adjustments

Post by cbye »

All parameters set

INJECTORS
1000cc and dead times

WIDEBAND
D10eld

-----------------Now my primary o2 was removed and wires hanging(not used) because wideband doesn't use stock wiring, I know not many people do run secondary o2, but sounds like could help closed loop operation?? Does s300 support a second o2? should I just connect it to the primary wiring??

MAP
stock

------------------Ok so im up running and datalogging, everything seems to be reading, but the o2 reading on Sensors window still has a reading even thou its not connected to o2 under car?? even thou not plugged in still reading 3.4vish............ cuz A/F on gauge lil off from sManager AF values, is this because of the o2 sensor reading??


Adjusting for RICH/LEAN Conditions
A/F gauge and sManager saying its running lean... I have rc1000's with fuel flowing thru AEM rail and reg at 45-50psi
would I adjust overall fuel trim? or low speed fuel mapping???

Which leads me to this question..... "there is the little flickering going on as the squares are highlighted/unhighlighted and doin there thing, and seemed to settle out on a four square block, is that normal?? but it was running lean so shut her down.... the engine seemed to be running ok, but AF was 17-18 and was scared to rev up and I wasn't exactly sure which adjustments to make, was smanger trying tell me something with the highlighting??

A wideband should not use the stock O@ sensor wiring. The best input is the ELD.

The highlighting of the cells is to show where in the tables it is reading. IF it is running lean then you need to add more fuel to the areas it is reading lean.

o2 after cat is now disconnected, still getting a constant 3.81v reading on primary o2 sensor. Is this effecting my a/f??? Should I just eliminate D14 wire??
