ECU will not go into closed loop mode??

[ryan15]

OK well I have worked at this for a while. As the title states my ecu will not go into closed loop mode on my rb20det. I have worked at this for a while.

I have replaced/tested my:ECT sensoro2 sensortried hooking up the narrowband out put on my wideband to the ecutested the sweep on the tps... all checks outmade sure the diagnostic knob on the ecu is all the way counter-clockwiseChecked for codesChecked for boost leaks/vacuum leaks sits at 17-20inHGfuel pressure checks out... im running a 190lph fuel pump and its sits perfect at idle.cleaned my maf

I dont know what to think it is. Under boost my afr`s are 10.7-11.5 pretty much perfect. Cruising it will vary from 11.0-12.2 afr`s. The only thing I can think of at this point is the ecu is bad. I will greatly appreciate any educated inputs... I am tired of getting 15mpg for the last 6 months.
