    Me either, I just go to the WB02 readout on the thing and it unfreezes.

    No CAN here, it would freeze on the laptop. The gauge worked fine.

    My AEM freezes when I first plug it in. I have to navigate to the WB02 reading in the handheld and then it instantly works fine.
  4. Unfortunately I have to drive this to work every...

    Unfortunately I have to drive this to work every day so 24 hours won't happen soon, but I'll try a couple overnighters leading up to the weekend. The current sensor is in an excellent location and...

    So the sensor I screwed in back in 2009 refuses to come out in 2020. Not even vise grips and a cheater pipe would touch it after 3 rounds with the propane torch. Hopefully I can score a new O2 bung...
  6. Well the sensor didn't show up today like I had...

    Well the sensor didn't show up today like I had hoped. Monday it is, I can't wait to have this buttoned up. It's already way better than before, start and restarts and tip in are solid and will only...
  7. Can do. I'm having trouble figuring out how to...

    Can do. I'm having trouble figuring out how to set up a 2D map to monitor cell counts in a way that mimics the MAF calibration map in the tune. How do I get it to read in a single column? It's plenty...

    I can easily redo the 18k route with a new sensor. How were the transients, gear changes, all that? I didn't choose a route where I could really load it hard WOT in 3rd gear, rather something that...
  9. Ugh, I was wracking my brain because the MAF was...

    Ugh, I was wracking my brain because the MAF was reporting consistently but the AFRs disagreed and I didn't know who to trust. I'll let you know when I have a new sensor on the truck. Hopefully it...

    No shit? Narrowbands look good? Just need a new WB sensor? Truth be told it's 10 years old.
  11. It gets better. My AFRs under boost seem to vary...

    It gets better. My AFRs under boost seem to vary from one mile to the next. I'll jump into last night's log too and see if I can spot a pattern. I will say that idle and cruise AFRs seem more...
  12. OK something's not right. The couple times I...

    OK something's not right. The couple times I jumped on it on the way into work the PE AFRs were in the 10s which is what I would expect to see in this cold air. Since I brought the laptop in with me,...
  13. That is a vacuum/boost referenced regulator. It...

    That is a vacuum/boost referenced regulator. It idles at 48, has 53 when you turn the key on and the pump primes, and holds 57 under boost. I figured it was lean because it was MAF only and that that...
  14. Actually the impact table changes made a night...

    Actually the impact table changes made a night and day difference in the truck. That still doesn't fix the IFR/MAF/VE (or idle airflow) that we both know was off so I'm holding off on any more of...
  15. I was able to verify in the daylight today that...

    I was able to verify in the daylight today that my fuel pressure holds all the way to a WOT shift so it's good to know for sure I'm not tuning around that. I figured the pump was enough especially...
  16. Do you need any more/less PIDs than what I have...

    Do you need any more/less PIDs than what I have in the log above?
  17. Alright, fuel pressure was 53psi with key on...

    Alright, fuel pressure was 53psi with key on engine off. I flashed the converter in 4WD to prevent wheelspin and it looked like the gauge went up around 57psi, I'll reverify in the daylight tomorrow...
  18. Thanks! I'm going to check fuel pressure at the...

    Thanks! I'm going to check fuel pressure at the parts store to have that as well.
  19. This is what I pulled off the PCM when I first...

    This is what I pulled off the PCM when I first got it. I bought this 411 from Justin at Blackbear 100 years ago and had him flash an 01-02 Chevy Express tune (12212156 OS) on there with COS5 plopped...

    Ha! Yes I am! I finally got off my ass on that one.
  21. A lot of the improvements aren't tune related,...

    A lot of the improvements aren't tune related, but my O2 sensors seem to both be working and I discovered a couple vacuum leaks, one was the evap vent valve of all things. At this point, I don't...
  22. If you were to upgrade to an LS1B PCM and COS5,...

    If you were to upgrade to an LS1B PCM and COS5, there is a table A0014 that is an IAT VE multiplier that's aimed at fixing your exact problem. I'm looking at doing another calc.vet to base this off...
  23. I went and horsed around with Stomp and wasn't...

    I went and horsed around with Stomp and wasn't really seeing any effect. I blew well past the EFILive limits for that table and the truck still never got a rich tip in. I'm going to put it back where...
  24. So I tried this last night and the map wasn't as...

    So I tried this last night and the map wasn't as effective as I'd hoped. Looking at the data plotted in 2D, however, was helpful. Another epiphany I had was seeing how the impact factor affected...
  25. Mine did the same thing. I nailed the VE years...

    Mine did the same thing. I nailed the VE years ago and the test drive rewarded me with commanded AFRs matching commanded perfectly. Once winter set in it was pig rich, so I switched to CLSD. Now I...
