Just trading my beloved 2008 FLHRC for a 2014 CVO Ultra. Having V&H 4 1/2" High Output slip-ons fitted, will I get much better performance by fitting either a V&H Powerpak or Power Commander, or will the standard engine management cope?

All thoughts welcome.

 

Standard computers will have a little wiggle room for just mufflers, but when you do the intake and headpipe mods you must run a tuner. Having said that, the proper tuner will help with your "just muffler" mod by fattening up the fuel/air mixture. Bike "should" run better and cooler. But if you get the wrong tuner, and there are dozens out there, it could do little or nothing for performance.

It is like the guy at the gym that wants a meal plan to bulk up so he asks the biggest guy in the gym what he eats and is given a meal plan that the Hulk uses.

You can get a lot of opinions from guys here, but unless they run your exact setup, they will only be guessing, not giving you feel of the pants or dyno reports.

Ask the manufacturer about your exact set up (in this case V&H) and take in consideration if you are going to perform future upgrades.

I run a Thundermax with Autotune, so it takes in consideration any mod you add at any time buy virture of the wide band O2 sensors.

If mufflers are the only thing you ever plan to modify, then you should be ok with no other mods.

One last word of advice, get one you NEED, not what is cheapest. Guys spend $20-40 grand on a bike and get the cheapest tuner on the market because it costs less. This is one area that you should get the "best for your setup" tuner

 

I was just thinking about this this morning. I am going to buy either a RG or SG when the 2017's come out, and have been thinking more and more about going with a CVO (if I go with the SG).

On all my other bikes I always do at least a stage 1. If I go CVO I was wondering if using a Power Vision with auto tune would improve on the stock tune if you change nothing else (being that they come with SE intake and slip on's). I don't like the fact that the factory bikes run lean, and my current bike with the PV and AT runs very good.

 

Thanks Magnetic. Guess I will judge how it feels then decide whether to remap
Cheers

Last two CVO's, I've just run with slip-ons and haven't had to do anything to the map. My 2013 RG CVO runs perfect with 4" Rineharts and no other engine mods.

 

I asked a similar question to Vance and Hines "...I'm curious if a FP3 would enhance engine performance/allow the engine to run cooler as I've heard/read the bikes come lean from the factory to meet EPA standards. As the CVO already has an upgraded intake and exhaust would only the addition of a FP3 be worthwhile?"
V&H's response "For the 2014 CVO Road King there is no 'stock' map available. But in this case, what you would do is select Vance and Hines Monster Round slip ons as the base map, and run the Autotune feature to dial the map in for your bike and riding style. It will richen up the mixture and allow the bike to run cooler and smoother. Also, the throttle progressivity would be a great feature for you to take advantage of. It eliminates the delay on the electric fly-by-wire throttle system and makes the bike much more responsive."

 

^^^ That was my exact thinking. After running auto tune on my PV2 on my Lo, the bike ran much better. I would assume the CVO would benefit the same. Richer mixture would definitely be better than the EPA lean tune.
