Building a 117 for my 12 sg. Full build. I currently have a power vision. Will adding autotune to it be as good as a thundermax? The pv has nice features when mounted but I never have it mounted when not playing with it. Kinda like how the tmax for tbw u can change maps and what not without the clutter. Will the pv with AT tune as good as the tmax? Don't really have reputable dyno neearby. Don't wanna blow money on tmax if AT on my PV will be just as good

 

Let us know in a month or so!

 

I don't have the PV but I can say the AT works perfectly with my PCV and engine mods. I would stick with the PV and add AT.

 

Also will it only use the wideband sensors for tuning when tge PV is mounted?

 

can't you use PV and the basic auto-tune?

 

Yeah but only tunes in certain parameters basically normal operating ranges I believe. Goinng pro with wideband covers all ranges if I'm correct? Definitely need to cover all parameters

 

It should cover the entire map. I don't use them but everybody that have them seems to like it. With only the wide band sensors you will be an Open Loop bike, the PV alone(not the ECM) will use the info from the wide band O2 sensors to modify/improve your tune. If you want to, after the wide band sensors do their job to your satisfaction, you could reinstall the narrow band sensors and return to a Closed Loop operation in the cruise range. You probably would save a fair amount of $$, sticking with the PV and wide band O2 vs the Tmax.

 

Buy the Auto tune. WIth a TMax you loose too many functions that will help protect that new 117. TMax does NOT pull timing if the bike starts pinging, for example.

The AT can get it close. Where in Ohio?

 

Cool. Auto tune to the PV is what I'm leaning toward.

Northeast ohio. About halfway between cleveland and warren

 

I think you have it turned around.
When running open loop the O2 sensors , wide or narrow, are not used/looked at by the ECM. Only in closed loop are they used.
