    Lly dsp5 tune hesitation/cut out from dead stop.

    He essentially said that won’t work with this particular issue and would still do the same thing 🤷. I don’t know enough to keep questioning him on what he’s doing, but I sent him a link to this thread if he’s at all interested in hearing your guys opinion.

    Yeah, I have Kennedys twin pumps.

    Maybe my truck has something funky going on or something. As big as this tuner is I’m sure he’s seen his fair share of Lly’s and I’d hope he’s familiar with all the usual issues and solutions.

    I don’t know anything about any of this so all I can do is repeat what I’m told. At one point he sent me a tune that as I understood it, was stock in all 5 positions off idle where the issue is occurring but after that had the increased power. This tune still had the hesitation. He later sent...

    I emailed him your suggestion and this was his reply: “They are correct... but the issue its having (Which I haven't seen before and no reply from EFI on it yet) is that its FORCING itself into the maps in the selections 2-5... Even though they are matched to stock - its not listening as its...

    Tune 1 did seem to have more hiss than the rest at first, but through the course of trying to figure this out the idle on the others has changed to have more hiss like tune 1.

    Thanks for the ideas, I will see if I can find anything else out

    Yeah, that’s pretty much where we’re at. He’s been good about sending me tunes to try he just hasn’t nailed it down yet. We have a few local diesel shops but I’m pretty sure they just get tunes from an outside source as well, and they all seem to be more Cummins oriented but do work on all...

    With the reputation he has I would assume he’d see it then.

    Is this something obvious that an experienced tuner would see and understand? I don’t know what kind of stuff he’s tried, but he did say he’s put everything right off idle back to stock in some tunes and it still didn’t fix it.

    try this, this is from one of the most recent tunes. i have a couple more from some of the other tunes if this works and we need to look at more.

    I’ll see if I can figure it out, I’m not much of a computer guy.

    Lly dsp5 tune hesitation/cut out from dead stop.

    I’ve logged it and sent it to the tuner a couple times. He says he can see it in the logs, we just have to figure out what’s causing it. He’s sent me about 6 different tunes trying to figure it out so far but so far it hasn’t helped. I can feel differences in the tunes themselves so stuff is...

    The first few throttle blips in the video I kept my foot on the brake. If you listen carefully you can hear the cut out right when I blip the throttle pedal.
