close loop issue

[5.SLOW]

ok got my 07 and finally got it down to so far that it not goin into close loop. it goes in close for 20 seconds and then goes back open.

my question other than 02 sensors what else cause this?
02 sensors are new.


any info be nice

I'd assume any sensor associated with the closed lop operation.

 

[hammeron]

i think engine coolant temperature and maybe even oil temperature are factors.

Codes? A datalog would show

no codes at all, I did a datalog but not sure how to read them.

still cant figure out why not gong into close loop, no codes at all just about ready to put back stock or just sell.

would put up the data logs on here but keep getting this.

Since you have long tubes with an offroad X-pipe, was the BAMA tune set up to compensate for the upstream O2 sensors taking longer to warm up, and have the downstream O2 sensors been disabled in the tune?
The only other sensor that could prevent the ECU from going into closed loop is the engine coolant temperature (ECT) sensor. However if that was to blame, the electric fan wouldn't switch on when the engine reaches operating temperature and you'd have overheating issues.
My money's on a faulty BAMA tune.

ya fan works and doesn't get hot. the down stream 02 sensors are post to be turn off. that's what am thinking and had another tunner tell the same thing or vacuum leak and haven't found any.
