The "Basic" uses your factory narrow band O2 sensors to preform the tune and the "Pro" uses Dynojets Autotune module with Wide Band O2 sensors. You'll achieve a good tune with both, but the Wide Band will get you the best tune. Lots of info on the Fuel Moto and Dynojet websites.

I have a 2012 Road Glide Custom (103) with a Big Sucker, Bassani Road Rage II and a Power Commander V with Autotune. My question is, would it be any benefit to get a Powervision, flash my ECM with my latest tune and then continue to run the Power Commander V with Autotune? Would selling the PC V be the best option after upgrading since the PV can use the same autotune module?

The PC V and Autotune has done a great job of tuning the bike, runs strong without any hiccups or pops and has performed flawlessly in the year I've had it on the bike so I'm very happy with the PC V. I do, however, like some of the features of the Powervision from my reading here and elsewhere but I really like the PCV's ability to constantly re-tune the bike in real time. I ride in all seasons and all altitudes, from sea level to 5-6K feet, and it seems to me that real time autotuning would be a plus given these conditions.

I suppose after flashing the ECM my fuel tables would autotune themselves down to near 0% change but there would still be some real time tuning for different conditions. Is the ECM's ability to take into account varying barometric pressure enough?

Just hoping someone here has tried this and maybe Jamie would chime in with his thoughts. Thanks in advance and glad to be a part of the hdforums community.

Im not talking about all the marketing crap and the b.s. used to sell it on how many more useless features it has over the regular power commander v, but actual real numbers like horsepower, torque, fuel economy, anything? Has anyone ever tested them against one another and actually noticed an improvement by switching to the pv? Im still looking for proof that its worth switching over to especially if you have the pc-v with autotune. I know for fact that the pc-v with the autotune installed is an excellent tuner because I am running it myself but I think that the power vision is just another device that they invented to get more money from folks who just gotta have the latest and supposedly greatest technology. Im stil waiting to see proof that it actually increases ANY performance on the bike.

I would place your objectives on the end result which is driveability, running quality and performance and it sounds like you are right where you should be.

As far as reflashing with Power Vision and then reinstalling the PC-V, you would not need to do that. Essentially you would use one product or the other, as the ECM is very capable of delivering the correct fuel & spark requirements with the right tuning product. The Delphi ECM is a speed density system meaning it bases fuel delivery on modeled airflow, it uses inputs from the MAP and IAT sensors to calculate air mass. On the correction side of the ECM it uses the factory nbO2 sensors for correction and fuel trim based on the target lambda/afr written in the calibration. Again, when calibrated correctly the ECM with the factory O2 sensors is a very accurate setup.

As much as I like the PV display and available information it sounds like I'll keep my PCV and ride on. I really can't fault the way the motor is running at all and even mileage is good, 45mpg or better, when I'm conservative with the throttle. Wide open runs and quick launches suck it back down to around ~41mpg but things are really fine.

Thanks all!
