    Shoot, missing the spark one. I had to redo them all. Anything you see that's off or recommend changes? I'll get those sources in there.

    If you type "source" in the search bar, you will see more then spark missing.

    Hard for you to see which limiters your hitting without all of the source channels/pids.

    Yes. Got it.


    I found all the source pids, and will get some more logs.

    Your also running pe very rich, causing your lift pump actual pressure kind of low.

    I was trying to prevent any knock at WOT.

    Lean it out? Less boost?

    Any richer then .780 isn’t going to help knock imo.

    I know your on e40, are you mixing with 87 or 93 for the other fuel ?

    Always mix with 91.

    Couple things I would upgrade

    1. intercooler
    2. colder spark plugs with gap set at .028"
    3. in tank lift pump if your going to be running ethanol blends over 30%

    Don't run pe lambda that rich.
    Don't remove cat protection.
    Get your boost (load curve) the way you want it before adding timing, watch your "manifold charge temp" and your air load - its doing exactly as you are commanding it with your LSPI tables based on your Octane Adjustment ratio...

    Go back and look at the first file I posted for you.
    Its not a "finished" tune, it only shows you the areas that need adjusting to control boost and get past some of the early limiters.
    Go back and look at the 2020 limited file you posted, it will also give you ideas of things to try.

    And if you want to remove the trucks ability to adjust boost (load) with fuel quality swings you could set it up like this.

    Im sure this is what most would call a "dedicated" fuel tune Rev 9.3.hpt

    Yeah, this is cool!
    I somewhat was able to accomplish something similar by forcing the 'Max Octane Modifier' to -1.00, forcing 'Inferred Octane' to 84. Thus, only using the 'Lo' LSPI Reduction table.
