    tune the airload tables and you can get full throttle in 6th.



    Also when checking load always check absolute load.

    ohhhh boyy! I thought I tuned out the limits based on one of your posts a short while ago. I also tuned the 'acceleration throttle request to airload' table and made it more linear with a slight ramp up on the low end. I'm assuming the input translates to degrees open on the throttle body? Here is what I currently have what would you recommend changing?

    Mat @OVTune,

    What is the current wait time for pending tickets. I submitted Tune Support Request 19443 on 9/9/20.

    I don’t want to submit multiple tickets unless I need to.

    Thank you.

    "Yet another thing I've discovered on this journey is how much the throttle likes to limit itself. I've been noticing when gearlocked in 6th doing around 60 if I mash the pedal the throttle wont even open 30%. It will slowly open up about 1/2% every couple of seconds."

    That's interesting... Maybe to help protect the transmission?

    Agreed! That, and the linear throttle have made a big difference for me. With the artificial torque limit gone, the engine feels more natural? Less robotic? Weird, I know.


    For the linear throttle, I did smooth ( CTRL +I ) this section to take out the big jump from 0.0% to 9.5%:
    upload_2020-9-17_7-18-49.jpg
    Note: The two cell errors in the 11% and 17% columns has been fixed and flashed.


    One big ask, @OVTune , with the digging around for Rev Hang and 1st Gear DFCO, can you please also peak around for the Anti-Stall function? It needs to exit my life. If there is anything that I can do to help that search on this end, please let me know?

    With these Linear Throttle and Air Loads changes, Anti-Stall is firing off like crazy when rolling around at idle or on the clutch with no throttle. The engine isn't going to stall, but it seems that any dip in revs near fires off Anti-Stall. I can make a vid or datalog? It's almost funny if it wasn't annoying.

    Thanks!


    And, are there Zoom controls for the Map Viewer? I didn't see that in the vF Instructions and none of the usual suspects seems to do it. I might be missing something though. I'm the CAD guy that makes folks seasick when viewing models. :rofl::rofl:

    Have you changed your spark plugs? I had misfires at less than 30k miles... turns out Toyota left my plugs loose.

    Because of you guys mentioning having loose spark plugs I went ahead and had mine replaced a couple weeks ago at 56k miles. It definitely runs better and the power is more consistent.
    I'm thinking mine were loose too.

    There is speculation here between bad factory torque and potential lean running in the Stock tune causing this. Do you have any idea here?

    Thankfully, all of mine were good.


    Also, how many 4Hi miles do you have now? :D

    Hard to say, but if I had to guess, they were loose from the factory. Not sure how it running lean would make all 6 equally loose. Although I did have one of them, I believe it was specifically cylinder 6, that was so loose I'm surprised my engine didn't feel like it was running on 5 cylinders.



    My truck is torn apart right now for pictures / install guide on the oil pan.
    I'm also putting it back together with the larger 900+cc injectors and setting up a tune for 15-20+psi.

    Mainly just to see how far the drivetrain goes before it really breaks. I wlll be very surprised if 4Hi survives 20psi launches

    Cylinder 6 was very loose on mine as well. That’s the one that had a lot of blow by residue on the coil

    Thanks! Someone posted an article where it was noted that an effect of lean running (don't want to say the word :rolleyes: ) could cause plugs to back out. I tried searching for that post but couldn't find it.

    All six of yours were loose? Wow! I think the most noted in other threads was two really loose with some under torqued.


    :hattip: Just curious.

    Some seriously nice parts in the TT kit.

    I had one that was loose - not falling out like some peoples, just like finger tight at best. I think it was the middle one on the drivers side, whatever number that is

    yea all 6 were pretty loose but cyl 6 was practically just sitting in there hanging out not even in the head it was so loose. (not literally).



    I think it's the opposite.
    The loose plug will create a misfire condition.
    Misfires are notoriously read as "lean" on an O2 sensor.
    So the loose plug is creating the lean condition.

    Again, wow! Hopefully, folks will get in there and check them. The left side wasn't as bad as I had thought it was going to be, with the plenum left on.


    Good stuff. That makes a lot of sense.

    Thanks!

    Am I guessing correctly that loose plugs aka misfire condition could also give me that "bumpy road" feeling? There's one section of uphill I drive home on everyday and it did there, every time. That section is a little bumpy too so I was so conflicted :annoyed:
    To explain it better it just felt like inconsistent power. I'm pretty sure it's gone now.

    No, after testing, testing, and more testing, I think the actual cause of this is the exhaust cam.
    From 1000 to about 2000 rpm, depending on load, the exhaust cam will go into a maximum retard state (for maximum overlap) and it causes this. I am able to consistently replicate it on my truck.
    I've wrote a patch to simply exhaust cam tuning, but it's not out yet.
