Hi All, I have ordered and flashed my 16 103 H.O.B. w/ PCV w/auto tune. I have the factory narrow band O2's and wondering if I change the Lambda figures to get more fuel in certain RPM range manually will the effect take place or will it run on it's own closed loop.. I am super new to tuning like this... normally it's a couple pilot screws and a great ear.. This modern day technology take a bit to understand... Any help would make my day.. Cheers!

 

My understanding is, if you are running the auto tune, the PCV will decide optimum A/F. I don't believe you can override the system.

 

I don't know.. I am no expert... but after trying tuners that use the original O2 sensors (PCV on Sportster and softail) and then trying a system that comes with their own wideband O2 sensors) I say spend the money on the whole Tuner with wideband 02 sensors.. .. my bike runs Thundermax.. great system... not much to tweak if any.. bike running strong for a couple years.. ZERO issues.. my next fuel system improvement is certainly going to be Thundermax.. just my 2 rusted cents.. :-)
