Must have proper NBo2 voltage to ECM for CL, or will have to tune with WBo2 AFR or lambda because INT and BLM will always =128. Must correct this before proceeding with tuning (See attached Excel file).
    ---Was the car always in gear when idling? If not, trans wiring not correct because never show being in P/N. It is automatic, right?
    ---Regarding injectors. They appear to be 30# from log. But FYI, your engine likely only needs 24#. Leave the Flow rate constant at 30#/hr, but the VE tables will likely required major adjustment once you can log with the o2 sensor connected .

    When you post another log after o2 fix, please also post your bin.

    ok. back, maybe now i can focus on learning this thing.

    Got the new o2 sensor in and wired, and it appears to be working. I'm getting readings from it now, and it's not throwing an SES light anymore.

    It is a manual transmission now, with a Dakota digital speedo corrector installed, which is why i get all the weird flutterings at idle. i've reconnected all the wires, ran them down opposite parts of the car, run the ground directly to the body at the box, and still get the flutter - probably going to have to figure out what resistor needs to be soldered in to stop the flutter if it's required.

    heres a current log and the .bin
