The best thing about using SAE numbers is that it enables us all to compare runs for different bikes in different locations, or that is the theory! Whatever, you have great numbers and wonderful torque curve - well more like a plateau!

 

Congrats for getting the bike sorted out...

In your post you said you did not want to name names because the various tuners tried hard to make things right. I understand that they may have given it their all, but the fact remains that they failed. I am sure that you on the other hand did not fail in you side of the bargain. You paid them all of the money agreed upon.

If you don't name names then one of us might go to one of them expecting quality work on our bikes, instead of just a really good try. I don't know about you but I pay for results not effort. You wouldn't be saying they are bad or evil people. Just people who can't seem to get everything out of a dyno tune....

 

Bottom end was never opened. Running stock pistons up top. Joe at Joe's Cycle Repair used my SE Pro Super Tuner software for the basic tuning but all other tweaking was done with my DJ PowerVision.

 

Thanks for the correction on the city. Actually I think its Mechanicville, NY (no "s")

 

I think that's a reasonable conclusion but I just don't feel right giving "negative press". I would say the vast majority of tuners are OK with basic flashing and stage 1's but given my experience (somewhat limited of course to the NJ, PA, NY area), I believe the vast majority of tuners just don't have the necessary experience to tune a bike with headwork or larger TBs or larger injectors. Invariably they'll say that its "too much TB or injector" for the build when in reality it's too much from the perspective of their tuning skills.

If you want a lesson from my expensive tuning travails, here it is. Find the guy that has successfully tuned exotic builds like superchargers and turbochargers and make the drive (even if its a long one) to have that guy do your tuning. If he's capable of tuning much higher flowing bikes, then a basic stage 2 or 3 should be relatively easy.

In my opinion, I'd rather have a tuner experienced with high performance builds stepping down to tune my bike than a tuner that generally just does pre-programmed ECU flashes and tuning on stage 1 upgrades that has to "learn" his way on a higher flowing bike.

That's just the opinion of 1 guy based on the experiences I already shared. Good luck!

 

And the smoothing is set to "0". Next time you get your engine tuned, ask your tuner for the graph set to 0 smoothing. Most tuners smooth the curve out by setting smoothing to 5. To see the "real" curve, demand to see the dyno with smoothing set to 0 and you'll have a much clearer picture of the engine's performance instead of hiding it behind the software's smoothing algorithym.

 

I think it's big of you to not trash and to explain why....Some are just not equipped or experienced enough to do some jobs...They should walk away from business if it's too big for their shoes...They may be great at some stuff but only adequate at others...
I have a local Indy that told me he could tune Carbed bikes really well but if i wanted my 07 tuned he would recomment another guy...

 

Dont get upset but I'm a little bit skeptical. 3 tuners all were with in a couple of horsepower and then you take it to this guy and he somehow pulls out 18hp and 14tq? Not likely, more likely a generous dyno. The important thing is your happy and it runs great with crisp throttle response.

 

Same thing I thought. I'd take it back to all 3 dynos and make pulls as is, newly tuned. Then the story is fully told. I have done this before chasing power left on the table. Result was a poor initial tune at dyno number one. After dyno number two and better tune, went back to dyno number one. Guess what, the new tune was confirmed, the numbers were within 1 hp & tq. Oh, and the initial tune guy had already been let go. After two years, you owe it to yourself and the build!!!! :-)

 

Heatwave, glad you're happy. I'd be interested to know what the baseline dyno numbers were; i.e., how much hp and torque were gained through tuning. And I hope you'll post some mileage and rideability information after a few tanks of gas.

As for corrected numbers v. actual numbers, as previously mentioned the correction factor was developed to permit apples to apples comparisons between virtually identical engines tested in different environments; e.g. a bike tested at sea level will have denser air (more oxygen) than an engine tested at altitude (less oxygen) to support combustion; colder air will be denser than hot air, etc.

If Heatwave's tune works great in relatively cool and low altitude NY, it may be a ping monster in the heat and altitude of say, an Arizona summer.

Again, glad to see Heatwave is happy with his build and tune.
