auto tune 02 sensor

[outback_imp]

Outback- lets put it this way- these bikes ran hot enough (and lean enough) from the factory that they had issues during the design phase with part failure...that's why our spark plugs ended up with their own little cooling fins as example.

Even a 100% stock bike would run better - and cooler- with a power commander, even without the autotune.

If you already have the power commander and autotune- might as well use them. Having a bung welded on is chump change in comparison.

When I did on my Arrow header- I left the standard smaller bung- just in case anyone wanted to use it in the future, just put in a cap, and put the larger bung next to it so I have both options going forward.

On my new 4-4 I just had 2 large bungs put in custom- as I also bought a 2 channel autotune box that I will install so I can tune the left 2 cylinders separate from the right 2.

Thanks PD for your help, and explanations, Ill be having my buddy weld in the bung for the auto tune. Just need to get a cheap little laptop to use it and save the adjustments.
