i am currently running 14.3 for my 2009 FLHT she runs pretty good what is everybody else running at and how is your power to MPG with the settings your running

 

You're running 14.3 in every position? (RPM and Throttle Position) My highest is 14.4. My lowest is around 13 somewhere. Don't recall. I have a map switch installed, but the bike has been running fine at 14.4 in the cruise range.

 

14.3 through out the rpm range except 100 % ran 14 and runs great still needs little more tuning due to muffler leak but surprisingly with the map i was running chnages were minimal.

 

It should vary depending on RPM and TP. In the cruise range (2000-3000 RPMs) I have mine set at 14.4 @ 5%, 14.6 @ 10%, and 14.5 @ 15%. I have a map switch and can revert to my rich map when extra cooling is needed, but that doesn't happen often. I taper the AFRs from 20-60% and have it set at 13:1 at 80-100%. With this strategy the bike runs great at roll-on and and mileage is very good once I get out of the city. I've never gotten great mileage in town with this bike (~37mpg) but highway is typically 48-50mpg at 55mph. I've never hit 50mpg with E10, however. I could set the transition range (20-60%) leaner but doing that causes a flat sensation until you hit 80%, much like what you feel with an old four-barrel carb. Power transitions are excellent the way I have it set now with no flat-spots or other flaws.

You should set 80-100% at 13-13.2:1 for maximum power. If anyone's interested in some light (?) reading, I did a write-up on setting-up the PCV-AT with a hardware switch to achieve maximum mileage, cooling, and power here.

 

although not autotune, i use sepst, here's my AFR table....

seems to be a decent balance against performance, and mileage. any comments on it, i'd appreciate. thanks.

 

oops....that's a bit small....lets try this.

 

I would definately read iclicks posts awesome information for sure. I would get a good base map from Jamie at Fule Moto and then impliment iclicks info taking into account where you live for temps and what your looking for in an acceptable fuel range and performance. Don't run them too lean for sure they love to run fat. My auto tune has just done a spectacular jobI run the switch too and what I did was set the rich map like iclick show you how to do. Then I took the map tha Jamie had set up for my bike and just moved the AFR's up only .3 in the fields below 60% the 80% to 100% still stay at 13 which is still very conservative but gives you a few more miles I can get 220 miles on a tank cruizing. Hope that helps I can not say enough about this auot tune set up with the switch bike runs so good it has just amazed me.

 

I've always been taught that optimal AFR for performance is 13.0-13.2 at 80-100% TP, and I have mine set to 13.0. This is only because it is Fuel Moto's standard setting and they know what they're doing. I think 12.5 is a bit rich for optimal performance and wastes fuel. Why did you set it at this value?

 

It is common for the WOT AFR lookup table to be in the 12.5:1 range in TTS, SERT, and SEST calibrations. They use this strategy to prevent detonation at WOT due to the increased combustion chamber temps from the 14.6:1 closed loop area. Also note the AFR table in these calibrations is simply used as a mathematical representation the ECM uses with other lookup tables (primarily the VE tables) when calculating fuel delivery. The PC-V/AT on the other hand uses a demanded AFR table with wideband sensors which samples, adjusts and maintains the actual AFR represented in the PC-V table.

 

as Jamie noted, those values are 'stock' in the map I started with from the SEPST.
