    While I know some may argue the fact that an EFI doesnt need to go to the Dyno, there's a few more reasons than just curiosity that is killing the cat...

    After several calls here in the AZ(Phoenix-Valley) I have only been able to find 1 shop that can actually Dyno a K9... Im not knocking any other shops or their ability, the issue is 2 things, 1 a long enough Dyno to house a K9 and 2, the ability to tune with ProTune from S&S.. Out of all the shop, which have come up, been named, none of them can actually do or have the ability to do based on those 2 things except for Average Joe's in Mesa. But this didnt come easy, John at Average Joe's has a great relationship with S&S, has the extended Dyno to fit a K9, and can tune with ProTune software.. Unfortunately, I have the Serial 9-Pin VFI module, and he doesnt have a Serial port on his Dyno, instead he has a USB port, so I had to find a USB to Serial cable with Prolific chipset. Off to Fry's Electronics I went, grabbed 2 cables hoping 1 would work, downloaded and installed the drivers from S&S on my laptop and we were in business. Called John back at Average Joe's and said, we are good to go, so he scheduled time for the Dog..

    Ill be dropping off the bike next week to see where we are, how the map is, and what if anything he can do to tweak it or make it better. With that being said, this is what I have, Ill be posting the results when i get them...

    2008 K9
    Stock EHC
    VFI - Unlocked Version (Programmable)
    Offroad Map (1 Map Merge currently due to front sight DTC and Rev Limit set to 10k)
    V&H 2-n-2
    BCT Baffles (6" from tail ends)
    585 Cam
    S&S Tuned Induction (Formerly named Dual Runner)
    Cleaned Injectors

    Stay tuned for more info...

    I would think think if you go North of 8 on a stock 117 it's likely to turn into a grenade.

    I wonder if at 10k they begin to sound like a rice grinder?

    The reason for the 10k is, when you have an unlocked VFI and map in adaptive is learning and tuning, if you leave it at the stock rev limit, it doesn't tune as well, so, it's been posted on here in another post that you set the rev limiter to 10k so that the tuning can learn the upper rpm range and tune better, not that it will ever see 10k it's more like tricking the VFI to make it learn better up to the normal rev limit...

    So what would you're tuner recomend for a normal rev limit with the 585 cam? Have you had any other work done to it?

    If your tuner sets the rev-limiter at anything over 6500 rpm, he better have a quick hand.
    585 cams, stock 117 heads, 117 engine, IMO wont bust a grape over 5800 rpm.

    Im pretty sure the "Normal" rev limit is still the standard, maybe 100/200 rpms over stock rev limit.. No other work than what I posted...if and when the time comes, maybe the 600 cam and work, but for now keeping it to just bolt on stuff...

    Good Point John.. I will make sure to let him know, he might for his sake, turn it back down while he is dyno tuning... :oldthumbsup:

    The HAND working the throttle controls the rpm. The revs DON'T automatically go to the rev limiter. Your tuner can go as high, or low as he feels is necessary.

    Dropped the bike off today, all the guys at Average Joe's we awesome.. Small shop, very personable and knowledgable too. Apparently, John from Avg Joe's is the only S&S Protune certified guy in the AZ valley. He informed me that he has been through all of Tom's classes and certifications and that when he tunes the Dog, he will be live with Tom from S&S while hes doing the runs which I thought was kinda cool.. Nevertheless, should have some results tomorrow or Thursday..

    Well... I have some Good and Bad news....

    Bad News - They didnt graph or do a full pull, back tire is so bald and based on the good news, they didnt need to do a full pull...

    Good News - The map thats in it and the tune its running is "Spot On" and cannot get any better according to Tom @ S&S, he said the numbers are perfect up to 95mph and there was no need to do a full pull...

    SO, when I pick up the bike, get the new rear on it, Ill ask if I can come down for a true graphed full pull for numbers...

    Sorry guys, slightly disappointed myself...

    You are obviously more interested in the numbers than I would be. I don't have much interest over 95mph so I could care less what my bike does over that. I've hit 100+ a few odd times over the years but it doesn't get my rocks off. I'll meet you at the bar just a minute or two behind.

    I guess I'm not a dyno guy but to each his own. I hope you get what you need

    Infamous, Im with yah man... Totally agree, I know theres always hype around Dyno numbers, but its a double edged sword, cause if you put up a good number, people tend to find ways to poke holes in it, and while everyone can argue or claim the dyno wasnt calibrated right, didnt do the pull in the right gear, didnt have the right tire pressure, didnt have the right altitude correction, etc etc etc, it was more curiosity than anything else. I learned a long time ago, Dyno numbers dont mean shit, anybody can fudge them. Instead, its a tuning tool to make sure your tune, fuel, timing, advance and everything else is at their optimum settings as well as safe so you dont fry your motor. Ultimately, this is what I wanted. So at the end of the day, they confirmed that, so Im technically ok with it, but just like anything else, curiosity killed the cat...

    Ive dealt with a bunch of dynoing on our Boat motors as well as my 4 wheeler motor, a good engine builder will even tell you Dyno Numbers dont mean anything and its just a tool used to tune and dial in the proper settings. :cheers:

    Yea, I've never had any of my stuff on Dynos I figure if it sounds good and runs good it's close enough for government work, right? And I'll admit I know jetting by sound and feel isn't as accurate as a good dyno tuning. But I do know a lot of people seem to care.

    haha this is true... In the terms on EFI, unlocked VFI module, and getting a map 3rd party. While the VFI will auto compensate +/- 20% its still a map that is completely editable. By normal means, when you start from scratch, you start with a clean file, the Tuner creates the map, then runs it on the dyno to see where its at, tweaks it accordingly for optimum.

    Because this was a 3rd party, not originally created or built with my bike on the Dyno, I wanted to make sure the parameters in the map were good, and if needbe, get tweaked accordingly..

    Knowing this and knowing that John and Tom @ S&S went through this, I think its safe to say moving forward that anyone who gets an Unlocked VFI and loads in this S&S Offroad Map to their Big Dog, its spot on and theres no additional tweaking that needs to be done. This is ultimately what I wanted to know, and they confirmed it was good...
