    Fixed it, decreased the VVT vs ECT multiplier to less than 1.0 up to 68C ECT. It runs great cold now, just as well as when warm and no matter the load.

    I should have added I was just comparing for Gen III stuff.

    I had a 230/232 112+4 and 236/244 110+4 (the grind was actually missed, supposed to be on a 112) and saw nothing WOT wise. I never...

    I see this post pop up a lot, haven't read all the comments but I see a lot of questions. My trials were posted early in the pages of this thread.

    I did some street and dyno testing with this....

    I have set TCC slip to 0 in most cruising areas.

    Also, I put the new fluid in mine after doing a B&M pan and a few flushes.

    I think the sensation I am feeling is linked to when the TCC starts...

    WOT TCC Lock 8L90E

    All - I have been trying to read, but haven't come across any good applicable threads for my question.

    I have read mixed comments on TCC lock for WOT.

    Here is my stock WOT TCC lock "normal"...
  6. I think I have it figured out. Cat light off was...

    I think I have it figured out. Cat light off was one issue, but the cam retard cold really kills it. That much retard at light load and cold was causing misfires. The VVT reduction multiplier vs ECT...
  7. From what I see this is due to the AC clutch...

    From what I see this is due to the AC clutch coming on and off. I think there is a min TCC slip with the AC on we can't see.

    Can someone else take a look next time you log and confirm? I know the...

    I love it. Louder than people lead you to believe, just enough IMO. Some claim they can't tell difference vs. stock - BS.
  9. Here is one, I can't get the others to load....

    Here is one, I can't get the others to load. After the first 1-2 shift, I go up a hill and then am light load in 1st getting it to jerk a little.
  10. Cold hesitation/jerking/misfire issues at light load - anyone else see this?

    All,

    The last thing I really need to fix on the truck tune (minus the annoying TCM relearn that has me back and forth with 4th gear shift flares after reflashing) is this cold hesitation or...
  11. 33350 Injector Flow Rate Density Multiplier - odd at 30C ITT?

    Just looking through my tune and others, I see the injector flow rate density has some odd jumps. If you look at 30C there is a significant drop, indicating a drop in density at 30C for the injector...

    Here is my stock and modified stock file. I only did the power upshift, downshift and inertia tables I am using. Check it out and if you try them let me know what you think.

    It made more noise, about all I could really tell. I never went on the dyno and the MPG change was not really measurable. Put it this way though, while I can’t say how much it helped I can say with...

    I believe the fuel compensation in and out of DOD causes some excess fuel consumption. I think properly tuned vehicle will see minimal benefit from DOD unless you do a lot of highway cruising. My...

    It is 100% stock. Yes, they are quite different. I was surprised.

    I compared mine to the 2016 and most areas I was slower, but I was a tick faster than my file. I think it feels good, some of the...
  16. I only wondered if it was current RPM since there...

    I only wondered if it was current RPM since there was a lot more definition at the bottom end. Projected RPM could be higher, but I don't see a case where projected RPM would be 1000 or anything low...

    Thanks for the info.

    Question on the RPM in the downshift table - is that the RPM before or after the downshift? Any idea?

    Take a look at a 2016 truck 8 speed tune. Some of their values were...
  18. When you say binding up, what exactly was it...

    When you say binding up, what exactly was it doing?

    I don't want to change any upshift and ride at higher RPMs. I have been slowly tweaking the downshift. I compared to a 2016 8 speed truck and...
  19. Nothing seems to make sense other than driver...

    Nothing seems to make sense other than driver demand torque % at this point. I asked support, we will see if they can answer.
  20. Torque Ratio for Downshift - what is the ratio of?

    I am trying to tweak the downshift timing tables, but I don't know exactly what the torque ratio is on the left axis.

    Can anyone help? Numbers range from 0.10 to 0.88. I really am trying to figure...
  21. Can you share your tables? Also, what is the...

    Can you share your tables?

    Also, what is the torque ratio? Not sure if it is current vs. desired or what. Any insight would be great.
  22. I haven’t had a need to really. The issue is the...

    I haven’t had a need to really. The issue is the commanded is freaking out in the log. I am happy with the lockup rates. The only thing I did to the pressure table was improve some of the transition...

    I reflashed the TCM just to be sure and there was also an update to the beta.

    The TCC slips at the throttle transitions. I had set zero slip but at low speed I was not happy with the feel of it.
  25. Commanded TCC Slip - looks like signal noise at times, not set to command

    Check out the attachment:

    91061

    Randomly I get some odd commanded TCC slip values. I am commanding zero but the signal looks like higher frequency noise.

    Anyone had any issues with this or...
