Fuel Controller for RKT Drop-In kit on '13 Pro

[ChickenMan]

Looking at doing a Drop -In kit on my '13 Pro and was just wondering if anyone was running anything other than the Boonie FC? I know that what Kelsey runs with, but is there any experience with PCV? or any others? Pros vrs. cons?
Thanks

Works just as good, split the numbers in half, boonie box is .5 to the pcv's 1, like if the boonie number is 14 at 8k rpms, it would be 7 points on pc5 at 8k.

pros vs cons-

pc5 more reliable IMO

boonie box adjustable on the fly pc5 can only have a map switch to toggle between maps otherwise need laptop to adjust

Is 1 number on the BD box 1%?

No, 1 number on the boonie is half a percent of fuel, where as 1 is 1% on the pc5

Not trying to jack your thread....

But is the fuel box a mandatory requirement on the 13's? Some of the guys on here say that the 13's run leaner on top. I want to try his cheater head, but I'm reluctant to do so if it is mandatory to run a fuel box. The last one I had (dobeck), just wasn't consistent. I would ride back to back days, same elevation (6-9k),temp(25-35f), fuel (91non-eth) and I would have a different performing sled each day.

So, Is a fuel box required to run a his head on the 13's?

Thanks, and again, sorry to semi-hijack your thread.

After looking at my instructions it appears that 1 number in the fixed mode = .5% and 1 number in the percent mode = 1% on the BD box...

edit: It looks like this only applies to the new boxes.

No, The head works great without a fuel controller and adds some good power at all rpm..

However; even a 100% STOCK SLED will benefit from a properly set up fuel control box.. The OEM mapping is NEVER IDEAl.. It is functional but not ideal.. So, adding a fuel control box always adds performance.

The 2013 mapping is leaner in the mid-band rpm arae it is the same on the upper rpm band.

I think the days of being scared of a fuel controller have past us.. the new Boondcoker box is extremely easy to set and once set, you usually never have to adjust it again..
The PC and the BD function EXACTLY the same. there is no difference in the metho din which they adjust fuel, they just have different interfaces.. 1 needs a lap top and the other has a direct interface...
1% on the PCV and 1% on the BD = 1%.. again.. the function the same

Hope this helps

Take a look at the new Dobeck Gen 4 AFR + ,closed loop system it comes with a AFR gauge that you can adjust fuel needs on the fly . Works off new load technology.
Just received mine the other day and started the install so far it is pretty straight forward . Off to the welder to install the bung next in my slp pipe.

I have run this setup and the 13 needs a fuel controller even with just a head at least in the higher elevations 8000 and up the 13 is soo much leaner we are having det problems even on bone stock sleds I run the boondocker box on all my sleds and never had a problem I have run just his head, his head with direct replacement pistons and the drop in kit after I got the fuel set never had a problem with det agin all three setups work better than stock and all require a lot more fuel but run really good I will be happy to give fuel numbers to anyone that wants a starting point. But you can pretty much add 10% from 6000 rpm up you can literally feel the power and rpm increase when you start adding fuel. like Kelsey said even a stock sled would be improved with a fuel controller

Thanks for the input. It brings me to another question though. So if you were hitting det with this head without a fuel controller, could that be countered by running a few gallons of 100LL? Or is that the midrange is so lean, by upping the compression (12.5 to 13.9 or whatever his high elevation head is) your compounding the already lean condition?

Does upping the compression ratio inadvertently make it a leaner burn? I understand that higher compression burn usually correlates to better burn efficiency. So a more efficient burn in this case also makes the lean fuel map even leaner?

At endstate, I want to run Kelsy's cheater head this year as my sled is a brand new 13 holdover with zero miles. Then next year do his BB. I have no problem with putting a few gallons of AVGAS in a tank if it will run correctly. I know who ever is reading this is just thinking that I'm a tight a$$ and just buy a fuel controller already and be done with it.... I know your right, just curious though.

Not trying to hijack the thread but............. Is anyone running a fuel controller on the 12 Drop in Kit??? Mine runs really good, but is there more to be had with running fuel controller on the kit???? Kelsey, do you have the PC V with a map you could be providing for the 11/12's??? Gonna need a little bit more to turn the 162" X3!!!!

Adding race or higher octane fuel will help with det to a degree but will not make a lean condition richer. In my opinion a fuel controller is one of the best mods or tools you can do on the cfi. In my opinion polaris dropped the compression so they could get away with leaner mapping to comply with EPA regulations which Polaris had to design a piston that will work for all conditions and alt and operators of the machine and hopefully stay together. With that said, what I have found on several different cfi engines is to install a good set of pistons put some compression back into it and tune the fuel mapping with a fuel controller richen it back up and get the power polaris took out of it to comply with EPA and have a engine that performs the way it should,

I have not personally run one on an 11 or 12 but have installed compression on them and they will hit det once in a while they are not as lean as the 13, a lot of guys run them without one and seem to be running ok, but to answer your question if I had a 12 I would for sure run a fuel controller
