Thanks for all the responses. I’m going to call fuel moto and talk to them a bit. I’m a bit between the pv4 and the 800$ one. I’m jut have a hard time swallowing that price. I like the auto tune feature of the latter as I don’t have much time to take my bike to get a tune. Weighing out the extra cost vs mpg and cost of fuel could be the selling factor.

 

Powervision in my book is the one and only way to go. Auto tune is a outstanding feature it wil do all the work needed to run your engine at optimal performance...

 

I'll echo whats already been said. Talk to Fuel Moto and buy from them. Use only the maps that they send you.

Don't wait around if you are going to pull the trigger. I got my bike in Oct and the unlock license for my PV-1 was $200; a month ago it was $250 now it see its $269 on FM's website.

 

so will the tuner come with one license or will that have to be purchased separately?

 

New tuner will license for (1) bike, additional bikes need additional licenses.

 

A brand new tuner license is included. If you want to use the tuner on a different bike you have to buy an additional license.

 

That's not a completely accurate statement....

The "Basic Auto Tune" feature doesn't really "tune" the bike... It adjusts the volumetric efficiency tables of the tune... It doesn't actually change the AFR (per se), or touch the timing. It just makes the called for AFR, a little more accurate between similar bikes..

IMHO... It's value is taking a tune map that was made on a bike that is close to your bike, and dialing it in to be an even better match to your specific bike....

If the tune you are trying to auto tune isn't close, then the auto tune won't help much... especially in demanding areas of the tune...

The basic auto tune uses the OEM narrow band O2 sensors... They are accurate between 14.3:1 to 15.2:1 AFRs... That only covers a portion of your tune map... usually in the cruise areas of the map... the high load, high RPM sections of the MAP can go to 13.1:1 AFR or richer... the narrowband O2 sensors will not accurately make adjustments in those area...

That is why all dynos and street tuners use wide band O2 sensors for tuning... they are accurate from 10.0:1 to 18.0:1 AFRs.... they will accurately cover the entire tune map... They also set the AFR and timing based on real time feedback....

Again, IMHO..... The auto tune feature is nice to have, and works well for dialing in a close tune.... but it will not create a tune, or change an inadequate tune into an acceptable tune...

 

I think that’s the most succinct explanation I’ve read on that subject. Thanks for posting that.

 

Well, kind of....

A new tuner will allow for one bike to be married to the tuner.... any additional bikes will need a license...

The difference is, unless they recently changed it...

If you buy a license to add a bike to a PowerVision tuner.... save that license info... that license will allow you to tune that bike with any PowerVision tuner...

For the original bike married to a PowerVision tuner, you can only tune that bike on that device.... You don't have a tune license, that allows for tuning on any PowerVision tuner..

I learned this when I had a PowerVision tuner, about 3 years ago, take a dump on me... It had one of my bikes as the original married bike, plus another two of my bikes and three friend's bikes on the tuner via purchased licenses...

DynoJet advised me then to make sure I married the same original bike to the replacement tuner... then all other bikes could be added with their purchased license info... If I had accidentally used one of my licensed bikes, as the original married bike to the new tuner, then I would need to buy a license to add my bike that didn't have a purchased license...

I hope I explained that so you could follow it... took me a few minutes to wrap my head around the concept...

 

So after I got home today I checked the air filter and it’s got a k&n filter already. So I’ve got filter and pipes. Now it’s just the decision on which tuner to use. For all I know it’s already tuned…..dunno. I appreciate everyone chiming in on the subject. I’m no stranger to tunning, I did all my own with my Z06 but Harley’s are new to me. I know nothing about these bikes.
