In Tunerpro RT is there a specific entry that would allow me to edit out the AIR system?

Or do I need to edit the actual hex of the bin?

For 6E, all you need to do is raise the "If Cool T < 14c, (58.5f) then divert" to a high number like ff (304 F) and the ECM will be fooled into thinking that the air is being dumped to atmosphere. There are more settings just prior to this from loc31E to the loc324 (for the temp). They have to do with higher rpm (4425), min/max load (25/100), and MPH (60)

The next thing you can change is the mv offset at 454 but if this is changed you also have to lower the O2 swing points by 100 mv as this is subtracted when diverting.

The O2 swing points are factory set 100 mv higher then 445 mv (fact) and then if air is added to the exhaust manifold (fact), the 100 mv is subtracted (this is a debated subject). The debate is weather the 100 mv is subtracted air in the manifold or no air in the manifold.

There are similar settings in 32 and 32B just at different locations.

For 6E, I lowered the rpm at loc31E to 225 to divert all the time (this rpm "4425" is where the exhaust pressure exceeded the air pump pressure). Then lowered the swing points 100 mv at loc459-473 and changed the offset to 0 at loc454.

There are two switch settings as to one valve or two in the switches section at 15 bit 2. The double valve is used when an air tube is run to the cat. First valve divert to sec valve or manifold, sec valve divert to atmosphere or cat. A one valve system only has atmosphere and manifold.

This is how I eliminated the "air pump" in the code. I am not smart enough to just "rip out" the actual code.
