I've got an Elite 1500 in my S4 TII.
I'm thinking about trying out the O2 control to aid with basic tuning.

Any Pro's or Con's?

 

Mine not back on the road yet.

But I would say yes, was one of the main reasons I got the ECU.

Hard part will be knowing what to make as the map as I'm sure all engines will like something slightly different.

 

i would start with a small RPM window you have tuned fairly close, and then making it bigger as you see how it works, but yes closed loop is good

 

this is the stock one for the rotor from haltech

I think it could do with some more load points around idle rmps (needs a 1250 and a 1750 line added.

Been easy to date to just press Q and the map auto calc to this chart.

 

Use it and the LTFT. You've bought an ECU that actually has auto tuning that works. Use it.
