TD closed loop - Feedback

[Janne339]

Does it work well? Have there been any updates since it came out last season?

Its pretty expensive so looking for some feedback before I buy it.

little No fuel gains for me. Run with many winders stock and tuned all on big trips we are always within .5 gal of each other

I don't know if the closed loop has had a positive affect on my fuel mileage it is so hard to tell with all the variables...it sure hasn't hurt the fuel mileage.

Have found closed loop to make fuel economy worse. We even compared two sleds same clutching, same exhaust, same tune, same day, same driving characteristics. Disable close loop and their back within a dollar of each other.

I just installed the TD Closed Loop cause I wasn’t happy with my data logging showing my AFR’s and afterwards looking now I’m very happy it works wish I bought it sooner. It’s pulling more fuel then adding with my Maxspool17 tune which is everything but cams.

that sled prob had a bad wide band 02 as mentioned above, if using additives in fuel ... they will deteriate fast.

nothing wrong with the O2 and no additives

Curious what temps you were riding in and also what your setup is. You run a 3" exhaust by chance?

I just asked Dave about fuel economy and he is seeing improved fuel economy from a ton of logging vs canned 3bar ss tunes.
