    Default B3601 and returning to CL

    I think i'm getting towards the end of doing autove and I think i'll be returning to CL operation soon and i was wondering if i need to change my o2 switch points because i tuned to an afr 14.12 for E10 gas. What do you guys think? is the computer going to try to adjust back to 14.7 because thats the only value the nb sensors can read accurately?

    on a slightly different note does anyone know which wire i need to tap into on the 02 harness if i want to send a simulated nb signal to the pcm from my wideband?

    thanks!

    It will "adjust back" to EQ 1.00
    The PCM and NBO2s don't know AFR.

    What PCM for the simulated NBO2?

    alright, thanks thats what i was wondering.

    i believe my truck has the p59 PCM. Does that matter for wiring the wideband into the stock wiring harness.

    I'm not familiar with the P59.
    It matters because not all PCMs are pinned the same.

    oh, ok i was thinking that i was supposed to splice into the connector for the nbo2 that i removed...maybe i'll go another route because i don't really want to mess with the pcm

    You can send the signal back to the PCM thru the harness for the NBO2 but
    you will need to know which wires are the 12v+, ground and the high & low signal.
    I used an old connector from one of my old NBO2's to get 12+ & ground for my LC-1.

    Here you can see someone has incorporated the stock NBO2 connectors to and LC-1 so it can be plugged straight into the harness.


    Connecting the wrong wires together will cause problems.
    Is the PCM an LS1 1mb?

    oh cool, i have a buddy that might be able to get me a wiring diagram for the nbo2.

    my pcm is a 1mb LS1 i believe. at least thats what efilive calls it when i'm connecting to it to scan or whatnot
