I hope to fire up my car for the 1st time tomorrow after a HUGE round of mods, including T-rex cam, headers, intake, etc. I have HP Tuners and want to disable the AIR, EGR, and rear O2's, I did a search and found the following. Some of what I found was for LS1 Edit, I want to know...Is this info correct and COMPLETE for HP Tuners?

Removing AIR:
-Disable all codes with (AIR), remove the AIR pump fuse, and raise the "AIR Pump on to 150*F"-it looks like HP Tuners has a "Air Pump Disable Coolant Temp", should this be set to 150* or a very low number??? Anything else to do to get rid of AIR with HP Tuners?

Removing EGR:
-Looks easy, under the "Engine/General" tab, click "Off". Nothing else? Need to disable any codes too?

Removing rear O2's:
Disable codes 137, 138, 140, 141, 420, 157, 158, 160, 161, 430. Anything else?

Thanks guys, sorry if this a topic that is beat to death, but this is what I found searching, I just want to make sure it ALL applies to HP Tuners and is COMPLETE.

Set the SES Enabled off on any codes you don't want as well as set the Error Code to 3 - No Error Reported.

As for the Air Pump disable, mine is at 14*.

You also need to disable the EGR codes IIRC the are 401-404

Hmmm. I only got one of those...I forget which one though. The other has never come up.

Don't mean to hijack the thread, but is LS1Edit or HPTuners the only things that can delete these? I also remove AIR and rear 02s on my '01 SS when I do my headers but all I've got is Hypertech PP3

Can't remove those codes with HPP3. Gotta have tuning software.

Another_User

Or a Tech-II. I think you would do much better with HPTuners. It's cheaper.

i dont know if this will be a problem for you, but it was for me. On an EGR car, there is a secondary timing table that increases timing for the area where the egr is in use. This is because the quality of air is worse and it can increase it. Without the EGR i was getting a lot of knocking in this area. I had EGR turned off but still had to zero out the table.

This is under spark advanced -> egr correction - add

What About LS1 Edit?

Is this "proper" for passing OBDII computer inspections? I
thought if you turned off the test, that flagged but if you
leave the test on w/ no report, it looks "functional" and
passes?

This is good info since I will be doing headers this week and eliminating my AIR and EGR and removing the rear O2's. I am curious about if I could pass smog with the proper tuning. I guess I need to search because I am sure this question has already been asked.

Can anyone CONFIRM this?? My SES for the rear O2's was on and the No Report selected...I stll didnt pass as the emissions test said "PCM NOT READY"

Maybe you should try O2 sims.

I just went through this with my car. You have to drive the car about 50 miles to get the PCM back into ready status. It just takes time and milage AFTER you have all the DTC deleted. I had to get the ready status back after I deleted the rear o2 430,420 codes, drove it around checked the status, checked OK. Took it through inspection and passed like a champ.

Well, if he is removing his AIR and EGR then he will no longer be emission's legal, so why try to fool the inspector when you may not pass the visual? This recommendation is for "Off-Road Use"

If you want to pass an OBD-II scan test, then yes, just set the codes to "No Error" reported and leave the "SES Enable" on.
