Tune PCV without autotune

I would like to setup my PCV with a secondary map to provide me with better fuel mileage for highway riding, but could use some help on what values to change, loading a second map, etc. Any insights would be helpful. Thanks to other posts about the PCV, I have found how to wire in the switch to change between the two maps, but could use insight on what RPM/TP% ranges I should modify from the base map to provide improved fuel mileage.
I have read almost all of Iclick's post with the autotune, but am hoping to get similar results (if possible) without autotune.

I'm gonna do the same thing. I got my PCV from Fuel Moto and Jamie said he would e-mail me a fuel mileage map that I can load. If you didn't get yours from FM maybe Dynojet can send you a map.

i think you're going to need the help of the experts. If you bought your PCV from fuel moto, they will be happy to send you another map.

I can manipulate my tune by changing my AFR values at different rpm/throttle settings, and the autotune will then change the fuel cells. I wouldn't have the slightest idea how to just go in and manually change my fuel cells without totally screwing everything up.

Thanks for the help. I will contact Jamie at FuelMoto to get another map sent to me for fuel mileage. I thought that with the PCV and the software that I might be able to just modify the values slightly to improve mileage within the cruising range, but wasn't sure how I would go about that.
I'll get my switch installed and send some pictures when I do. I'm going to use a stock harley toggle on the fairing (have 1 open spot and an extra switch from when I installed my passing lamps). I'm going to use some of the posts here to wire it so the light comes on when the switch is on.

That makes things much easier for dummys like me!

Ditto, it would be great to have a PWR/ECO toggle.....

I'll try to remember to take pictures as I get the switch wired in. I'll also keep a parts list of everything that will be needed for the install. I already have a switch (just need to get the "spot" lettering off it). It would be great if I could get PWR/ECO printed on the switch instead.
