Picked the Power Vision on the advise of many on the Sportster and Buell forum for my 1200 Sportster after I did the standard stage one mods. Ran great. Now that I have a 1250 Hammer kit on it with new cams , 10.5 compression and head work expecting 110 hp from it. Will get it tuned by the best guy I can find in Eastern Pa. ( Still Looking, but am thinking Pocono HD).
Bought a duel licence for the Power Vision so I could put it on the Low Rider too. Put a Target tune on the Low Rider, got a map from Fuel Moto, ran a couple auto tunes and she is really running well. The Power Vision is now back on the Sportster. My mechanic is me.

Two ways to add pictures. When you use the "Quote" you can click on the paper clip in the top row and attach a picture. The second way is to click on the little yellow box with the Mountain and sun in it to insert a picture in your response.

 

Both tuners will give you a good tune but I think the PV is easier to use. We have 2 PV's on 2 bikes with stage 1 and the bikes run great after just 3 Basic Auto Tune sessions. I don't need any more power and have all the acceleration I need. You might want to try the PV before you buy cams, you may realize you don't really need them.
Good Luck

well. would you look at that. you can teach an old dog new tricks. thank you my friend.
about the dyno chart.... it is a vance and hines pro pipe, i believe jamies reasoning for listing it as a fat cat was because he modified the the baffle abit.. btw. its deepand loud

 

I'd buy the Power Vision again for sure. Not that I have to, just buy a license.

Look up Cook's Customs, in Mount Vernon OH. They will dyno tune using either the HD tuner or the dynojet. Good guys to deal with. Dave is his name.

Other than that, buddy of mine lives in Columbus Indiana, and has had good luck getting dyno tunes done through Mann's Harley.

 

I'm not sure people understand what the wideband set-ups can and cannot do. I use Auto Tune Pro on my 05 Deluxe. It didn't have O2 sensors from the factory.

Auto Tune Pro will adjust VE's and can also adjust timing. It uses a different algorithm.

Autotune Basic sets AFR's to 14.6 across the board and retards timing 4 degrees during an autotune session.

Autotune Pro sets AFR's to 13.0 and can adjust timing (retard only).

Neither mode will adjust the tune AFR's, and that's why it's important to have a good base map to work from. Your AFR's are set in the base tune. They can be adjusted manually if you understand what you're doing, but it can be tedious and time consuming.

If you have a good base map, and Fuel Moto's are excellent, you should be able to get a good tune using Autotune Basic, as you already have good timing and AFR tables. Most people are very happy with these results.

It's important to remember that neither Autotune Pro or Target Tune set optimum AFR's... and that's arguably the most important parameter of the tune. They can improve the tune, but they don't do it all.

I haven't used TT, but it sounds interesting.

I've been meaning to move the Autotune Pro module to my 2010 FLHRC (Stage-2 with Andrews 48 cams) to see if it improves the tune, but it runs so well with a Fuel Moto base map and some autotune sessions, that it hasn't been a priority, and I'm getting ready to bump the Deluxe to 95/98.

 

Thanks for helping me understand the differences. So if I had to choose between the two, you think a dyno tune would be a better choice than a Target Tune?

 

I think that if you plan to buy from Fuel Moto, they will supply a good base tune and you'll probably won't need either.

I would start with the Fuel Moto tune and run a few autotunes (Autotune Basic). In most cases that's all you will need to do. Most people are satisfied with Autotune basic provided they have a good base tune (AFR's and timing are set in the base tune). Autotune will adjust the VE's for your bike. Most of Fuel Moto's tunes were developed on their dyno and produce excellent results...so all that's needed is to adjust the VE's.

If you don't like the results you can always get a dyno tune and hope to improve it.

I haven't used Target Tune, but from what I've read it has some very nice capabilities, but it won't set AFR's.

The Andrews 57 cams should produce the results you're looking for. I've also seen some very nice curves with the TW48's in 103's.
