Bike back from Dyno, results!

I'm not worried about the time, but it seems others are.

I am perfectly happy with it. I just want to see what it does when the weather cools down because yesterday was really hot. I really could care less about fuel mileage. That comes second to me. I'd rather have my bike a tad on the rich side anyways.



It was a crap shoot. I knew already going into it that I wasn't having ANY issues and it could be a waste of $$$$. Come to find out, it wasn't.

If I really cared about what exactly was done to it, I could just go into the tune and look at all the numbers and compare them to the numbers of the old tune, but it's not that serious. Jaime from FuelMoto is pretty recognized and that's where I got the previous tune from, but it wasn't for duals. It most likely was pretty spot on and just needed some minor tweaking.
 
r8rs4lf,

my tuner also took about an hour and 20 (or so) minutes. 8 hours to tune a bike seems completely too long to me. I agree with the poster that mentioned most tuners go with what they have and just tweak the map for your specific bike. or at least that's what i've seen. I remember taking a friend's rocket 3 to get tuned. the guy took quite awhile because he really didn't have his own map to start with. he was working off the dyno "stock" map even though the bike had slip ons and a k'n air filter.
 
I think the majority of people think tunes take around 3-4 hours when in reality that is just what most shops charge. Almost like a minimum charge if you will for using up time on the dyno. And of course the shop isn't going to call after after an hour. This is just my opinion of course.

I took my bike on a longer ride today and can definately tell the difference. It's like night and day. Real smooth through the band and powerful when I hit it. The sound is just phenominal! I'm definately happy with the results of my combo and how the bike has been tuned.
 
Always difficult to compare dyno sheets but if all were equal your sheet imho is about average, actually a bit low. My findings are about 75/88 but it really depends on how you think it runs.
Also, 3 hours max for tuning with a PC. The SEST, SERT, etc. are longer with a competent tuner. IMHO of course.
 
KWS motorsports is a huge dynotune/sportbike/race center about 2 miles down from my house. They're known all over the sportbike/drag race world. Race teams, have race teams etc etc.

The owner - Kevin - who dyno tunes 1000's of bikes for competition once quoted me 225 and 2 hours to tune my Harley. He does a lot of those too apparently. I asked him how much for say a Busa or a Gixer? Told me 350-500 4 hours or more. I asked him why the big difference? Are the sportbikes that advanced or hard to tune? He said:

"That engine configuration [Harley] has not changed much in the last hundred years but the major difference is you only have 2 cylinders and it only revs to around 6K RPM. Anyone can tune one in a few hours."

I also got out of him:

"If you are letting someone bang on your bike for 4+ hours to tune only two cylinders, no variable valve timing or exotic heads/cylinders, on a low RPM engine, you are paying them to learn and you're getting ripped off."

Kinda made sense to me.

Average is cool with me since it's nothing more than a factory 96" with bolt ons. What I was really looking for was that it's running as efficient as possible. Plus, now I have a hard copy of what kind of HP and TQ I'm making if I ever decide to dyno again or do internal mods which I have no plans for.
 
that is a very good point. because when he was writing me up he charged 3 hours I believe. it was 325 for doing separate cyls' and he added some timing.
 
Doesn't make sense to me. Different tuning devices and different combo's take a different amount of time. Tuning a PCIII or PCV with Tuning Link with a map in basic mode probably takes an hour. Bump it up to an advanced map and it takes longer as you are doing individual cylinders. Now work the timing tables and again it is adding more time. On the other end take a 117, 120 or 124 with high compression, high overlap cams and a big throttle body. That can easily take all day. WOT doesn't take that long but working the areas where the bike spends most of it's time, takes time. Anybody that tunes a bike with a TTS or SESPT and does it in less than 3 1/2- 4 hrs is either extremely good or hasn't done a proper tune. Just my .02.
 
I totally agree with that statement.

My bike is basic, so a basic tune was in order. I more than likely got charged 3-4 hours, but it was done in 1.5. Does it bother me, not with the way the bike runs now.

The thing that gets me is when people are misinformed that a tune should take 3-4 hours just because that is what the shop is charging. These guys who come highly recommended are making a killing on their tunes. It's all pretty much the same, just minor tweaking. And when a guy comes in there with a different set up, it may take 3-4 hours, but believe that tune will be saved by the tuner to use the next time round so it won't take him 3-4 hours again.

That's another thing, how competent is the tuner. Many different variables it seems.
