Is dyno tuning about to be a thing of the past?

All this talk about maps and auto tuners and plug and play....have we forgotten that there are LOTS of carbed bikes out there that this stuff dosent work on. Those of us with carbs will keep the dynos in business for a long time coming.
DOWN WITH EFI, CARBS FOR LIFE! lol

Dyno vs. Race Tuner
I know you can't tune a bike as well as a dyno with the smart tune feature of the new race tuner or with the autotune the PC's now have but it sounds like you can get pretty darn close. With the advancements the fuel management systems have made recently, do you think that dyno tuning will be a thing of the past for the average motorcyclist and only be used in race applications in the near future?
I use a V&H Fuelpak on my '08 and a Power Commander on my '06. I am a bit partial to the PCIII because of the support available from Fuel Moto. My 2 cents.

As Harleytuner said earlier, the PV will be compatible with the AT-100 units to tune the entire AFR range. It won't be a true auto-tune process, but as I understand it you'll be able to have AT establish trim values and those tables can be applied to the ECM base map at a time when the bike is not running.

I personally don't care for dyno tuning for two reasons. 1. Hard to find a really good dyno operator, 2. a dyno runs my engine much harder than I do. I just don't like to rev or load my engine like a dyno does.

I agree on all counts. The closest verifiably competent tuner in this area is 70 miles away, and I also don't like the idea of thrashing the motor repeatedly to the extent required for a dyno-tune. Besides, I feel that there are other means to establish a good tune that will get me very close. I also have relied on Fuel Moto for my maps and to date I haven't been disappointed. After adding Auto-Tune 18 months ago I can see how close their maps really are by the trims that are created.

I hear this all the time and I don't get it. If your bike can't handle a few quick blips to the rev limiter then it isn't a very good build to begin with. (My opinion). The people running auto tune, V-tune or smart tune are doing the same thing only on te road in an uncontrolable environment. On the dyno we can monitor what is going on with the bike, not to mention it's not being run without a tune for very long for the purpose of data gathering. I understand you start with "close MAPS" from fuel moto so this might not relate to you as much, but there are people out there that don't have starting MAPS anywhere near their build and the first thing they do is head out on a half hour data run with a MAP that isn't correct for their bike. I've changed cams 3 times this summer, full tune everytime plus when it was built last year. That's 4 tunes in a year. Changing cams again this winter. Of all the In over 10 years on both our dynos we've only ever had 1 motor failure, and it was a part failure that would've happened on the street regardles of the dyno. I'll start a thread asking members to tell there dyno horror stories and see what we come up with. I'm sure there's a few, but probably not many.

On my 2002 Fatboy I tried canned maps, custom maps from similar builds, so forth and so on. The bike never ran right.
Like someone said above. No two motors are identical. One map will not work the same on two similar motors. Just ain't gonna happen.
I put my 1K miles on my Road King with a canned map. The bike was running hot and popping. Trailered my bike up to JD's Cycle Works and let Dave tune it. Yeah, it cost a few bucks and it was a haul, but now I have a great running bike. If my internally stock 103 can't take a few pulls on a Dyno by someone who knows what they are doing, how am I supposed to trust it going 70+ mph on the Hwy?
I didn't do it for more power, I just wanted my bike to run right. And now it does.
If you all want to waste your time playing with Auto-Tune, Smart-Tune, or Looney Tunes, go ahead. While you're doing that, I'll be riding.
