Question to you folks that have the power vision and the target tune. What are the benefits to adding target tune? 2012 road king with woods 555 cams high flow intake Reinhart true duals. Stock O2 sensors no other mods to engine. The bike currently runs fantastic IMO and I'm very happy with the performance of it. I guess I'm just curious what I could be missing out on with the target tune i.e. better gas mileage even more torque... What are the bennies of upgrading... Thank you in advance for all your knowledge my friends!

 

The only benefit in my opinion after owning Target Tune, is that it allows you to road tune the bike over the full operating range. This is a good approach if you do not have access to a shop with a dynamometer.

I believe that the best solution is to dyno-tune with Wideband Sensors and use narrow band sensors for daily operation. The narrow band sensors have better dynamic response and are more accurate.

 

Definitely interested in more info on this , having a PV4 on my bike right now .

 

Hulkss... So if I'm understanding correctly I'd probably get more out of a dyno session. If I remember correctly most dyno guys install wide band 02s to do the session then put the stock back on...

 

Yes, however, if it's running great, ride it. Not every dyno session ends well.

 

The wideband sensors do add to accuracy of the closed loop AFR delivery when engine wear is considered. Using them at the dyno and then taking them out only gets you accurate to those targets below 14 at the point in time of the dyno. With ring wear, intake dirt, and injector buildup it won't be accurate a couple years down the line.

 

Well, adding a TT to a bike allows the Wide Band O2s to make the tune optimal. The TT does not add power, it keeps the bike in parameters of tune using the WBO2s to make the changes needed for where you are riding. If you don't have a dyno'ed bike and run the PV3 with TT then it allows the PV to tune the bike that much cleaner. If someone wants to argue with me, then go ahead. But the question I ask back is this, why do dyno guys tune with Wide Band O2s? TO get the best possible sampling possible. Having the TT on a bike will give you that based on the tune that you are running.

Chop.

 

It allows to calibrate the areas outside the closed loop cells. It also allows to bring a different build into range quicker. Then you can finish the tune with the narrowbands turned back on. They are much more accurate where they are safe to use. I'll only use one device to tune with and it allows me to tune with both sensors at the same time. Tuning to the target afr or lambda is very accurate. Narrow bands give you the best sampling by far because they sample every time the cylinder fires.

 

Narrow band O2s only sample a small portion - thus narrow band. I am having a hard time following your logic. Are you saying that Narrow are better? If so then that goes against, basically everything that we know...

 

Narrow bands read everywhere, it's where you let the ecm pay attention to them which is the closed loop area of your map. Who's the we?
