    Tune File Breakdown??

    What do these Tunes do? Yes, I KNOW WHAT THEY DO, but is there a Breakdown of what the differences are between them, or what the Number Designation at the ends of them mean?

    For Example...the Stage 1 8350 30 73 Tune. Ok, so it revs to 8350, what does the 30 73 mean?....or Stage 1 8500 101. What does the 101 mean? Do you have to run 101 Octane Fuel with this tune?

    Right now, in all, I'm seeing:

    90hp Org
    E85 102 Final
    Stage 1 8350 30 73
    Stage 1 8500 101
    Stock File
    TEST - E85 NA 101
    xx beta - 101 t
    xx beta - 8900 101 32 race
    xx beta - 8900 102 27 race
    xx beta - Stage 1 8500 33 73 knock 2
    xx beta - Stage 1 8500 33 73 Marc version

    So....on my 2015, STOCK 60hp 2up Spark, what one of those is safe to run on Pump Gas?

    Stage 1 8350 is what I have.
    I do NOT know the MAX. safe rev. limit for the 900ACE, so I don't know about 8500 w/o valvetrain mods. I have been told that the 900ACE can take very high revs reliably, but havn't heard much in conformation here from 'those in the know'. I know some of the folks have loaded the E85 tune and found the limiter somewhere north of 9200.
    I was informed by V-tech NOT to use the 'beta' tunes unless asked/told to by them.
    I believe I read somewhere that the numbers following the rpm numbers are to do with timing advance.

    I was running the 8500 rev limiter with no problems for the first 33 hours on my spark. When it came unhooked I would see as high as 9000 rpms. Now I am running the 8900 rev limiter on e85 hooked up I am at 8600 rpms when it comes unhooked I see just north of 9100 rpms. I have the stock valve train and have never noticed any valve float.

    The filenames are written in a special way so you will understand what features they have.
    Example

    48 8500 169 35 35 AGR 101

    48: Size of injectors (VT11 IS 1100 CC VTECH)
    8500 = RPM limiter setting
    169 = Fuel value, larger value is more fuel
    35 = Ignition angle mid range
    35 = Ignition angle top range
    AGR= Agressive throttle response ( NOR = Normal but still more than stock)
    101 = Version of the file, Higher number is newer version

    Select a map that is the best for your setup.

    Carl how are you liking the magnum pump from glenn?

    Was it worth it, my pump after this year will be replaced as its on its way out the door.

    Cheers

    The pump is great it has better acceleration, when coming out of corners it holds more rpms. It also stays hooked up better in small chop. The durability of stainless is far superior to cast aluminum.
