Ive never modified the harness, but I'll see if i can swap harnesses before i buy 2 sensors.
there's a 6 page thread where i couldn't get my LC-1 to work after 5 months of trying. It's sitting in a box until i have time to mess with it again.
A lot of people have mentioned swapped O2...
Here's the log with the good tune in SD/OL.
Keep in mind, this tune was for 317 heads, ported f.a.s.t. 90, 9.4:1 compression, 239/247 .624.624 114 cam. (i know...)
The current setup is L76/L99...
UPDATE:
i loaded the tune i had from my old setup that patrick did for me in 2010.
it immediately started trimming between 20-32% fuel and popping, stammering, backfiring like before.
i ran...
UPDATE:
Now I'm 98% sure it's a hardware problem.
I deleted everything except a few pid, tune, log, and map files and reinstalled V8 and V7.5 from scratch. Then i flashed a tune i knew worked...
It idles fine in OL but lean-surges when it starts trimming.
It runs fine with no load but falls on its face with more than 25% throttle.
MPG's are atrocious.
At this point, i must have screwed up something last year when i was trying to make my wideband work, because the car ran great with the tune from my old setup. So I'm going to reinstall the whole...
I switched one out to test that theory. They're good.
Until i get it figured out, I'm just going to stay SD OL and command it to run richer. At least it'll be safer, and drivability should be better.

here's a log i just recorded after correcting the calc_pid.txt file.
it's still cutting a lot of fuel and stumbling at low RPM's
once i get the LC-1 installed into the new car (old one got smashed in a parking lot. so i bought a V6 car for $1400 and swapped everything over.), i'll check everything again and keep trying.
Oh hell. I'll try that now, make a log, and get back with you.
I made a serial cable first. I'm pretty sure i had the terminator plugged in all the way. is it supposed to be difficult to press in...

the log file was before i added 10% to the VE's
the intake gaskets are good. the exhaust is pretty good now. good enough to where it shouldn't add fuel from leaks
when i command it to 11:1, i assume it's actually closer to like 13-14:1
it...
A few months ago i posted about a weird stumbling issue i was having with the car. since i had gotten my VE's within 2% across the board(using LTFT's), i ruled it out as a lean condition and assumed...
For PE's I'll just use the wideband on the dyno..... Or just let patrick do it lol
Thanks. Found it. After 1 log/tune, it runs drastically better... as expected.
after months of battling with my LC-1 i finally ripped it out and said fuck it.
now i'm just doing as well as i can by tuning with fuel trims.
i can't figure out how to copy my LTFT log MAP...
Immediately after selling my 03 silverado to a family member, it starts going into reduced engine power mode with a TAC code. So far i've replaced about 6" of wire to the TB connector and soldered...
I'm also wondering this. I want to take the shifter (and possibly steering wheel) from a car like my 2010 malibu with tap shifters and get a custom OS to support it.
i quickly figured out why my TCC wouldnt stay locked, BTW. when i updated my OS, i forgot to disable the misfire tables.
update: i finally got motivated to hook it up again. i disconnected the LC-1(analog), and the scan tool WILL log now. i also found all my orange analog connectors so i can jump A1+ and A1- together...
ok i'll try this.
LC-1. i never got it to work serially. and i can't get the BBX to read the analog either. i only see it on the scan tool (before it stopped working completely)
i did that and it still wont record.
