    Of all the vehicles I've ever had tuned an AO tune has NEVER been an option:

    92 Civic Hatch - e85 / 93 tunes, have to change them if I swap fuel
    04 SRT4 - 91 and 93 oct tunes, upload with fuel change
    10 Ram 1500 91/e85 tunes, upload with fuel change
    13 Optima SX 91 and 93 Oct tunes, upload with fuel change
    15 STI - 93 and a back up base 91 tune, have to upload with fuel change as well

    So in my experiences, an AO tune is extremely unique and I've never heard of anyone ever able to do it let alone master it the way these guys have. If you know of anyone else on the market anywhere that can do it with literally any other car please share, I'd love to know in earnest. I'm curious though what your experiences are that would lead you to believe that an auto adjusting tune is something that isn't unique.

    It’s not a gimmick if it works??? GH is the only tuner that allows the ecu logic to adjust for the octane. All others you must upload a new tune. Sure lms makes a tune for 87,89,91,93 but you must load a new file. More of an convenience factor than anything. Kind of stretching to make an argument out of nothing? Trolling??

    Oh boy where do I begin.... The stock sho calibration does not swing boost mapping based on inferred octane. My calibration does. The inferred octane is like a long term fuel trim but for timing. This "long term timing trim" exists on the factory calibration. Not only did I speed up this learning, when the inferred octane changes my calibration also scales max allowed boost up and down accordingly. The stock calibration does not do this!!!!!! If you have full boost and no timing as would be the case with low octane fuel the cats get hot real quick. My strategy prevents this and works very well. On 87 octane my calibration runs stock boost. As inferred octane increases, so does boost. So it is different than stock. You can now wrap your brain around that Eric Morris.....

    Eric Morris is probably a SSI troll trying to learn how to tune.

    Not for nothing. But it took a “troll” like Eric Morris to ask a question we were all curious about and pretty much had no clue how GH accomplished their AO tune. So thanks Eric and thanks Matt for the answer!

    Pretty sure in post 54 algorithm and strategy can be interchanged.

    The multiple threads on LMS's V11 issues was making me want GH. Logging both tunes in cold weather and the LMS tune having dangerously low fuel pressure confirmed I made the right choice switching.

    I too like a lot of us have spent the money on LMS. I haven’t experienced any issues I only drive mine in the warmer weather though. Is it a cold weather issue mostly ? I know I read a few had it it some cold instances , also people have had the tune for a few years without any problems the all of a sudden fuel pressure is not there and there is issues. Is that what I’m heading for waiting for it to fail. Just can’t switch right now tuners that is. Matt could have a jump over sale ! ( wink wink ) his tune is definitely at a good price it’s the plugs and sct that hold me back for now. Can some one else use my LMS items ??? Then I can make moves.

    LMS has fuel pressure issues which is more prominent in colder weather. Although I did see a guy on FB throw a rod in the last few weeks. If you are having any kind of hesitation issues be very careful regardless of how cold it is.

    I believe LMS does have updated tune files that make somewhat less power but maintain better fuel pressure. I'm not going back but would want to log before I run any update from them.

    I talked to Dan at LMS, and there is a fix. However the updated tune files does make less power to maintain fuel pressure. There are better tunes out there that make more power and are deemed safe regardless of what LMS says.

    My AJPTurbo E30 tune makes more power then 98 percent of the LMS's cars (meth ones included), has zero fuel pressure problems, and averaged 20.1 mpg over my 1200 mile road trip this past week. Average highway speed was 83 mph.

    The fuel pressure issue in the cold baffles me. It you tune for a max VE instead of a boost number, then the boost will dial itself back once temps drop automatically to achieve the same VE.
