Setting-up the PCV-AT for mileage and cooling
#41
OK I just installed dresser duals, V&H new design fishtails, the screamin eagle "ventilator" performance breather, and a PC V. I tried several maps and am currently using the canned M15-11-023. The bike seems to be running really hot and my mileage is in the dumps,,,,
I am thinking of getting the AT and I have seen some bung adapters that should allow me to use the sensors with no welding etc..

suggestions appreciated!!!! Thank You,,,,

If I had an '09 or later bike I would go with the Fuel Moto 2-1-2 or 2-1 pipe, the PCV-AT, AC, and an oil cooler. I would then set-up the switch as per above.

Going to Auto-Tune is a solution but this an expensive ($300) option that may not be necessary. It will definitely give you the option of selecting the AFR's you want at any given point in the RPM/TP grid and getting your bike tuned optimally would be a matter of getting the right advise on how to do it. Re-reading the OP in this thread would be a good starting point, then ask questions on points that need clarification.

IMO all you need is a good map for the PCV. Give Fuel Moto a call even if you didn't buy the PCV from them, as they may be able to help. They don't routinely provide maps for non-customers so don't get your hopes up, but they may still be able to help. If you decide to upgrade to Auto-Tune you should definitely buy from them for the customer-service aspect if nothing else.

,,, looking forward to getting my map dialed in,,, no regrets,,, love my sled and the new fishtails are perfect,,,
I haven't talked with the PC folks about my map but I am guessing they would just recommend a dyno... I'll call fuel moto and buy the AT if I don'y get anywhere with a map...
Thanks!!!

On another thread about rigging a map switch without Auto-Tune, some of the other respondents wired their ACC switches through a relay to have the LED illuminate. That's easy without AT since you can have either map work with an open or closed switch. With AT, "learning mode" (closed-loop) only works with a closed switch, so here's what I came up with.
I bought a Radio Shack DPDT relay #275-218 ($9), which has two banks of secondary pins (see attached diagram). I have the PCV on one bank connected to Pins 2 & 6. This means when the switch is not on (i.e. current not flowing to the relay coil and LED), those pins are closed and Auto-Tune is in learning mode (closed-loop, lean). When I activate the switch and the LED is on the relay opens Pins 2 & 6 and Auto-Tune switches off (open-loop, rich).
Note that odd-numbered pins work exactly the same as the even, so you can attach two separate devices if you want to. I used a DPDT switch because it leaves the option open to have the same switch activate something else, like maybe an engine or oil-cooler fan by attaching 12V (ignition switched) to Pin 5 and the fan to Pin 3.
Note that "normally closed" means the switch is flowing current in both secondary circuits (Pins 1 & 5 and 2 & 6) when the coil is not activated (switch off). I connected my PCV this way so that the LED is on as a warning when I'm in the open-loop (rich) mode, which is where I normally won't be running. Also note that if you don't ground the black wire on the switch the LED won't illuminate, and the O/R wire must be the 12V source.

What a great Tech worthy thread
I love soaking up as much of this stuff as possible. I've been of the notion I had achieved maximum 'bolt-on' power for my bike. While my riding style doesn't require 2 separate maps, the one Jamie provided me with has not only bumped up the 'get up and go' it's also bumped up my mileage from 38 to 45 mpg. Leaning out my ride 'just' for economy just seems like tinkering for the sake of tinkering. It's what makes these things work that really fascinate me the most. Which is probably why I like working on mechanical watches. If anyone comes up with an Autotune for a Rolex let me know.

I wouldn't want to say what you might get, but my '07 gets 47-49mpg at a 55-60mph cruise with not much stop-and-go, around 45 at 70mph, and a lousy 37 or so in town. This is with E10 gas, and I've hit 50mpg a few times with real gas. I haven't figured out a way to get the mileage up in town, although I have recently fooled around with leaner ARF's from 20-80% as an experiment. I added 0.2 (leaner) from 2000-3000 rpms but haven't had a chance to check it yet. I can't tell any difference in the way the bike runs since the change.
