are you happy with your PC-V auto tune

before i pop for $300 I would like to know how good the auto tune works. My PC-V has a very close map now. I'm just wondering if I'll notice a difference.

I am using both he PCV & Autotune in my 09. I am very happy with how they work. I like tinkering the the AFR to get max fuel mileage and rideability. I was getting 38 mpg with the fuelmoto map that came with my setup. Bike ran great everywhere but the gas mileage went down 8 MPG (from 46 to 38). I have tuned it back to 42 MPG and kept the 3000+ rpm part of the fuel map to keep everthing cool when I want to ride more agressively. As I change things I can let the unit tune to my changes with a trip to the dyno shop...I like this.

2 Thumbs Up on Auto Tune for PCV

I recently added the PCV to my bike along a complete 2009 2-1-2 exhaust, Jackpot slip ons, and an SE AC. FuelMoto supplied a map with the PCV and the bike ran pretty good. 3 weeks at the intial install, I went ahead and added the Auto Tune Module. I finally got to put in some riding time this afternoon and was riding 2 up with my wife. After about 20 minutes I would have to say that the bike went from running good, to running great! This is my first bike with FI, but I have tuned/jetted many a carburated MC. I like that I can look at the fuel trims the AT has calculated and accept or reject them. I'm not chasing every last bit of HP, but I do insist that my bikes run great. The Auto Tune sure made it easy to get mine running the way I like. I'll be installing an S&S 551EC cam sometime in the next couple months, and I am confident that the Auto Tune will come through for me again.

Note: The documentation indicated that there would be 2 AT modules required, but the kit I got from FuelMoto had a dual channel AT module which made for a much cleaner install!

I had the pc5, then bought Andrews 54 cams, V&H Pro Pipe and the autotune module. Still playing with the fuel trims but the bike runs great. I like tuning it myself instead of paying the dealer to beat it up on the dyno and then getting 30 mpg.

Very pleased with PCV and autotune.

I added the autotune when I swapped out the stock header (with cat) to the V&H Power Duals. Noticed more bark and more pull, especially when I roll on more power in 6th gear.

I've been getting 45 mpg, so I can't complain there.

I have a Fuel Moto mapped PC V on my 08, with Fuel Moto ac and jackpot slip ons. I have no complaints. I sat through a tech session on the autotune at the V-twin expo, though, and now I want one. I think that there are some worthwhile gains to be had from it, and rather than spend a bunch of hours on the dyno, I'd rather have it tune to my driving style, etc. The layout of the auto tune program is very cool, where you can set target air fuels by rpm, throttle position, and gear. As others have said, I'd like to be able to lean out my 6th gear cruise, to get some mileage back. And with the ability to change maps on the PC V, I think some neat stuff can be done. The shop I work for dyno tunes cars, and I wish we had a tool like this.

And the best part is that you could effectively use the auto tune to populate the maps, and then sell it, if you don't plan on making any other changes. I'm considering renting mine out when I'm done with it.

Sorry if these are stupid questions - just trying to understand how these different tuners work.

If you're manually tweaking values and even dyno tuning, isn't the Autotune pointless with your setup? Or is there a benefit to the AT that gets you close (or closer than a canned map), and then you go in and fine tune manually? How do you prevent the AT from undoing your manual changes?

The simple version: After you ride with the AT turned on for a while, you come home and shut off bike. Later you hook up laptop and accept the trims the AT has calculated. The trims modify the base map accordingly. Eventually the base map is dialed in as the trims the AT calculates become very small.
