Power Commander 5 and Auto Tune Info

Had trouble with my used 07 Street glide that I bought used from dealer who didn't know history, but only 1200 miles. Could not get it tuned right, tried all the usual stuff then I installed PCV with autotune and let it do it's thing, within 2 hours this thing ran perfect. Now I'm getting just over 40 mpg up by 20% and come to find out the bike has had the cams changed. the new PCV with autotune is a great product.
 
I also agree, and after three months using it I can attest to its ability to auto-tune any setup. I went from stock with the Fuel Moto Power Package, then added 255 cams. The PCV-AT took over and in a few hours of riding through all ranges had written a good base map. I then changed the target AFR's to leaner in the cruise range and it has been auto-tuning ever since to my specifications. So now I can switch between the richer base map, like in hot stop-and-go traffic, to the leaner AT mode any other time.

That said, I do believe that most people don't need AT if you already have a Fuel Moto base map for your bike's installed hardware. It is very accurate and if you don't make any further changes (cams, etc.) you won't need to alter the map or add AT. AT is for those who make incremental changes to their setup or like me get their rocks off tweaking techo marvels like the PCV-AT.
 
Here's a few photos of my PC-V installation.

Photo 1 shows everything tucked away under the right side cover.

Photo 2 shows the front O2 sensor and harness connector

Photo 3 shows the rear O2 sensor. The harness goes straight back and I have zip tied the connector to the starter motor cable.

Photo 4 shows how I ran the harness for the front O2 sensor. The harness is zip-tied to the other wires in the main harness tray under the fuel tank and exit just in front of the negative terminal of the battery.
 
The auto tune feature works very well. In a matter of just a few miles my bike was running beautiful. It's real easy to accept the trims and you need to do this. It will narrow the correction factor the PC has to make, thus making it easier for the PC to adjust for changing conditions as you ride.

Anybody that buys a new bike that even thinks they may change something down the road, should consider the PC-V w\Auto tune. It can correct for altitude, humidity, ambient air temperature, etc. No SERT can do that!
 
well , getting my PCV finally brought in from USA from a friend. still havent seen any photos of anyone with ABS how and where they placed the unit and wiring. any help out there. I have the factory alarm and its real tight. cant see how i can place the PCV into right side cover.. any photos with someone with ABS would be great .
 
Doesn't the system do that anyway? I thought the bike had air temperature and MAP sensors that would help with the compensations you're talking about. Do systems like the PC-V bypass these systems? I seem to remember reading somewhere that the PC-V still tapped into this information but it's been a while and I could certainly be wrong about that.

Can anyone please clarify?

Thanks,

Steve I think he was referring to engine modifications. With a stock bike you can run stock pipes, maybe a muffler with no problems. When you start adding stage I, cams, etc the stock computer cannot compensate enough and in addition will try to maintain EPA mandated 14.7 eg. The PCV with autotune will allow the changes without having to get the bike dynoed after each upgrade.
 
It doesn't impede anything by having large trim values, but just takes a bit longer for it to auto-tune initially. Once the trims have been established there is no difference between a base-map value of 10 and 0 trim (i.e. after accepting trims) vs. 20 and -10 trim in a given cell.

I purposefully have left the rich settings in the Fuel Moto base map's cruise range with often double-digit negatives in the trim tables for those cells. This is because I use a switch to toggle between that rich base map and my leaner Target AFR's for gas mileage. I keep it in AT mode (leaner) 99% of the time and switch to the base map (richer) when the going gets hot in summer traffic. Even with 14.5:1 AFR's in the cruise range my bike doesn't get hot enough to be a concern except on rare occasions, never above 230
