I have a stock 14 SG with a FP3. I am about to add RCX exhaust and wondering what would be the best map since they don't have RCX on the V&H list for the FP3. I do not have any other modifications and am running the stock air cleaner, might upgrade to K&N but for now I am stock.

V&H Monster Rounds are what I have found but most folks running that have some other modificaitions. I don't want to have to Auto Tune as I have not had good luck with that on the stock setup.

 

I would probably use the monster rounds but for best answer I would ping Chris from V&H either through the customer support app on the FP3 or here on the site (I think his user name is vcneely)

 

Thanks, I pinged the website, haven't heard back yet. No hurry but I heard they are quick to respond so hoping I hear back soon.

 

If anyone is interested, twin slash round slip ons. They said run a tank then do auto tune.

 

If you're reluctant to use the auto tune, then do what you said you were going to do and just load the twin slash map. It seems the twin slash map will be the closest in specs to your RCX, right?


You could also load a V&H generic slip on map. Pic the generic slip on map that is the closest to the RCX slip on's then do an auto tune.


Here is my experience.
I bought some Cobra 3" slip on's for my Breakout. Initially I loaded a V&H map that was pretty much the same as the Cobra 3" slip on's. The bike ran awesome.


I ended up buying an Arlen Ness Big Sucker. This time I loaded a generic map for 3" slip on's then did an auto tune session. IMO, the V&H map felt smoother and better. I ended up loading that first map back and am currently running an auto tune session with that map.


Good luck.

 

Same thing happened with a stock bike map for me. Ran auto tune and it started running like crap. Just loaded back the base map and runs great.

 

I have been running this a while and forgot that I had the bike on Auto-Tune shortly after this setup. I have roughly 500 miles on AT so decided to upload and it's running great. I don't have mileage yet but am taking a trip in a few weeks where I will run several tanks through it and will track if then. I can say without a doubt, the RCX and FP3 are in sync and this bike is running really strong. I didn't think just slip-ons and a tuner could make so much difference but wow.

 

I just got back from a trip to the hill country and checked mileage twice. The first time I got 46.3 and the second time 45.8. That is riding in the Texas Hill Country which is about as close as you can get to mountains. Considering how this thing runs I am really surprised by the mileage. There does not seem to be any more heat and using the app and the air temp on the bike things seem to be normal.

 

You got that kind of mileage with auto tune?Im going to get one.

 

That's what I did on 103 cu in, SE slip ons, stage 1 intake. Did Autotune up to 80% throttle. 4500 rpm. Couldn't be happier. No plan to do stage 2.
