I am using HP tuners tonight to remove the VATS and disable the O2 sensors from showing no feedback.

Let me know if there is anything else I need to modify or edit. Just to get it to run.

Thank you

 

Should be good to run after removing vats.

 

Rear 02's...bank 2 sensor 1, bank 2 sensor 2....air pump, evap solenoid and anything emissions related....

In addition, when you delete VATS etc, do a write entire, sometimes it does not stick if you just write calibration...

T,

 

It should fire just fine with VATS removed. Set the emissions stuff to no error reported. You may want to disable COT if you aren't running cats.

 

What is COT?

BTW, it finally runs.

 

I think this should be Bank 1 Sensor 2 and Bank 2 Sensor 2, right? "Sensor 2" is the post catalytic convertor 02's, and "Sensor 1" is the before the cat sensors? If not I cut the wrong plugs off my harness.

 

You are right, I am dislexic....carry on....LOL

T,

 

COT is 'cat overtemp' it is located in Engine Section of HPTuners. May want to lower your fan temperatures and remove skipshift (if this is a manual setup).

how do you disable the codes to not report. Do i go to eng diag - dtc's and there are two columns SES enable and Error. The SES you check mark and the Error Mode has a drop down with no error reported, mil of first error, mil on second error and no mil light. this is the tune from my 07 chevy suburban with a twin turbo. I removed wye pipe and put staright pipe with sensor1 o2's
