I bought a PV-CX for my 2015 Roadmaster from Fuel Moto. Those guys are absolutely awesome and do they know how to tune! I had the PCV installed and ran a few different maps but none of them ran like this tune I got from Fuel Moto.

It took me forever to uninstall the PCV, it was more difficult taking it out than installing it. I felt like a surgeon removing a alien parasite that wrapped itself around the spine of a human body. Total PITA!

Anyway, flashing the ECU was a cake walk. The bike fired right up and I could hear the difference immediately. This didn't surprise me too much because I have the Stage 2 cams installed and the stock tune sounded different than the canned maps I used from Power Commander V.

The test run put a smile on my face. Throttle response is quick and snappy and feels like a cable type throttle. 2nd gear acceleration is insane! I would warn the faint at heart to not roll too heavy on the throttle in 2nd while in a turn...the rear tire breaks freely. The engine never stopped pulling hard straight to 5500 RPM. I didn't push it harder than that as I know the limits can be raised but have not verified if the tune I have does in fact raise the RPM limit.

I am very happy with this product and the tune I received from the Fuel Moto guys. Their customer service is top notch as well.

I have been lurking and reading the posts on the fuel controller for a while. Thanks for the info.

Amazing device. Have a pretty decent understanding of the mechanics of an I/c engine but never fully realized how Important the electronics controlling it is until I got the PVCX. Best money spent on a bike ... ever!

Happy to read this. Bought the CX this winter for my 15 RM when they were on sale. Got the bike flashed, but have been under record snow and ice since. The driveway finally thawed this week and should hit 40s this weekend. Looking forward to getting out tomorrow and feel the difference firsthand.

The Power Vision does make Tuning Simpler and Easier to Understand, but there are still times I say God Bless my Carbed Bike .. Only Electronics on it are the Ignition and Speedometer ..

What did you have to do when removing the PCV? I purchased a used 2014 Classic with the PCV installed with Dyno tune. Now I have the CX. Did you need to reinstall the exhaust O2 sensors. My bike has Freedom True Duals and 4" slip one. Just want to know how much work I'm in for!

Thanks!,

You need to have the narrowband OEM o2 sensors installed if you want close loop operation. Depending on the map you plan to use for the PVCX, it will have 14.7:1 in the Target AFR table, which relies on the narrowband o2 sensors.

I am just the opposite. I recently sold my '76 Shovelhead. Though I had the S&S Super E tuned in well, I still like the flexibility of the modern ECU's on our bikes for tuning.

With the PVCX, most folks don't need to know anything about tuning, just pick the appropriate map, flash, and go. No consent tinkering needed unless you just like to. Since the hardware of the bike is not touched (nothing added), everything functions as designed....fuel calculation for MPG and fuel trims based on narrow band sensors, etc.

What is the Appropriate MAP is the Key .. Also My A/F Ratio sure as Hell is not 14.7 or would have just left my Bike Stock .. Is more like a steady 13.6 and still getting 45-48 MPG .. Didn't really have a big problem with Modern ECU's as you call them until they stuck CANBUS in there .. But can live with it on my Scout .. Thank God Victory didn't go that route until 2013-2014 so my 2012 is safe from it ..

Since the FM flash my TS111 runs smoother at any rpm. I was not expecting this. I was expecting better throttle response and I got it. I have a Thunder Mfg AC and punched out OEM mufflers plus cat delete and it runs great.

Nothing wrong with 14.7:1 for certain conditions...light load cruising and idle for example. On our bikes, that is how you tell the ECU to stay in Close Loop. You certainly would not want a straight out 14.7:1 in all the cells. You tune for the best performance depending on RPM and Load.

I like CAN BUS, but to each their own!

Better Word for CANBUS is Tattletale .. Tells every time you redline , drop the bike, etc.. And defies all the Electronics Knowledge I learned over a lot of years, try adding LED lights like you would normally on any other Bike without CANBUS .. Will be having fun doing so ..

It is that. My mechanic asked me how the bike handled at 110mph. My jaw hit the ground. Then said, you aren't supposed to put the bike in gear with the kickstand down. It is a tattletale to the max.:rolleyes:

well now.... with the pcvx does the tattle tail tell you everything? not being sarcastic, asking a question
Honestly I don't know if the PVCX is capable of this , I doubt it, but when the ECU is hooked to the Dealership Analysis Machine It Tells All .. Why my Warranty was denied to begin with on the Scout .. Had been Redlined several times because had been Dyno Tuned and showed evidence of being tuned by a PCV because of the Lower Air/ Fuel Ratio , Showed every Code that had been thrown and that it had been dropped .. ( Because of the Wimpy Kickstand not aware of when first bought it ) And that's why I don't like CANBUS as well as the fact have to rethink electrics all over again the way it's designed ..

Is there a way to hack or jail break into the memory of this Canbus animal to erase memory and leave no trace that it was erased?Why is this system not disclosed in the owners manual?Seems like a form of illegal search and seizure!Do all new vehicles have this capability!

Most New Bikes do .. For Sure the Newer Indians, Harley's and Victory do ..
