I am currently running a PFC D-jetro and just bought the Bushur GT30R turbo kit. My problem is that the Bushur kit doesn't include an 02 sensor bung on their elbow for re-installing the factory front O2 sensor. I was wondering if I even needed the front O2 with the Power FC? I noticed an option for O2 feedback while learning to use the Commander, what does this option do? Is it for some sort of closed loop feedback or possibly for idle learning? Anyone know?

 

From my understanding the option to disable O2 feedback is only used when tuning, where a wideband sensor should be used. During normal driving the PowerFC uses feedback from the O2 sensor to make adjustments.

 

this is my understanding as well.

 

Thanks!

 

Yes you can turn it off but I usually turn it back on when done tuning as it does make things a bit smoother and helps with fuel mileage when you're not boost like crazy.

 

If your tuning is good enough, no need for it. But if you have it and it is accurate, it is even better.
THE PFC is an awesome standalone.

 

+3 on that one...
