    Hey guys I'm looking for a little tuning advice. Car is a '98 turbo LS1 running a 99+ pcm and OLSD. Everything is good except maintaining a warm idle on warm restarts. Cold starts are good, hot...

    Yes it's on 1 of the analog outputs. So what I'm logging is the most accurate because its coming straight from the serial connection on the LC-1. And the gauge is just interpreting the values...

    I don't believe so. I've had these over 10 years I bet. You think I have the voltage offsets wrong for the gauge maybe?

    serial lc-1 logging

    How close should my logged lambda be to what my Dyno Tune gauge is displaying? I seem to be logging .2 AFR richer than what my gauge reads. Not a huge deal, but it would be nice if they were...

    Wanted to update you guys, it's fixed! I'm embarrassed to admit it, but it was my fault the whole time.
    I pulled the pcm out (behind the dashboard) to backprobe the pins and see what was being sent...

    Yes, 98 gauge cluster. I've tried scaling the calibration up/down/inverted just to try and get the gauge to move. But it seems no value affects it so far

    Scratch the last thought, it seems like my Ohm reading and my 1.2v reading match up. The pcm uses variable voltage to interpret gallons and that all seems inline. So now I'm back to thinking its...

    Still didn't help unfortunately. I'm not sure how I made something so simple, so complicated! I'm wondering if the sender crapped out or the wiring is jacked up somehow

    Would I just full flash right back to the stock 02 OS, then swap in the fuel segment and do a calibration flash and see if it works? If it does then start copying over all my current tune tables? ...

    So far, nothing has affected it, stays pegged. Ended up running it way too low today not paying attention and almost ended up on the side of the road. Added 15.7 gallons, oops!

    Still doesn't move when grounded. Ohms show 82.3, car has probably 1/3 tank in it. Are you thinking this might not be tune related since it seemed to load the segment swap?

    I don't get any errors, it says that it copies and loads over fine. I'm doing the standard 02 Express Van segment swap that everyone does, but must be missing something!

    Ok, good deal. That's the way I had it setup originally. When I saw the "not supported" that threw me off and got me worried. Sound like I should be good to go. Thanks Joecar

    There is a good chance I misinterpreted what you guys were talking about in the post I linked. I thought you were basically saying a "not supported" would read "ready" at the emissions test.
