You will need to load a base map into it, If you have a laptop it can be done yourself. There are dyno tuned maps available on this site that wouldn't need much if any tuning.

You can load the base map using your desktop before installing the PC5. You will also need to get the O2 sensor bung welded to your header, if I remember correctly it goes around nine inches from the mounting flange. there is some pics of this on this site just search the threads.

The PCV operates off of a map just like the PCIII, what it does is slightly adjusts the map for changes in the weather/elevation and such. When I say slightly I do mean slightly. Its like a computer controlling the manual buttons on the PCIII(which is like 3% at best which is almost squat if your trying to tune instead of tweak). You need to tune the map and then the PCV can tweak from there.

My PCV can adjust the base map up to 20%. You can set the allowable adjustment limits from 5-20% from base and also turn it off to run base only.

What was the deciding factor to go with the FMF over any other programmer?

The further it has to adjust the worse of a job it does, 3% is about it on the accuracy. This is some of the "trouble" some tuners are having with the PCV.

I went with it because because it's from fmf same as my exhaust system,I don't have a computer or labtop,didn't want to weld anything to the header. Just seemed an easier fix somthing I could put on...hopfully without having to send it to a dealer.witch I found out later there are ajustments on it.I hope I can just install it and it works.maybe I won't have to send it to the dealer for ajustin it.I just wanted a quit fix the others seemed complicated to me.I had to have the dealer put the power commander on my vtx 1800 when I put hypercharger and exhaust system on it...and it wasn't cheap

You will be able to just plug it in and ride but there a bit hit or miss with running properly. Having the bike pop and die on decceleration is common with them. I know it's a bit late now but if you would have purchased a PCIII from Fuelmoto they load the maps in them for you free of charge and cost about 280.00. For future reference for others that may read this thread Vendors like Alba and EHS put allot more effort and dyno time into making there maps for Dobek controllers than say FMF of HMF. Simply stated any vendor that has a XX race quad will have much more invested in there map process.

The Dobeck style fuel controllers do fine for the average trail rider with mild to medium builds, the PC fuel controllers just allow a more precise fuel map adjustability. One thing the PCs have over all the others is you can take fuel away from the stock map like in situations were you are runnin a larger injector for big bore/stroker builds. The main thing it has over the rest is 250rpm increment adjustability which is why its more precise on the fuel metering. I have had a couple of XX owners that dont want to deal with programming the PC to dropship it to me and I load my map for them and send it on to em.

Sure, any fuel controller will be better than none at all. Ive actually told a few guys that if thats all they ever wanted to do was the Big 3 and just trail ride then the Dobeck style fuel controllers will do just fine. Thats what I started out on.
