04 GTO help?

[jschmitty19]

I was wondering if anyone could help me modify tune my 04 gto. I have pacesetter headers, lindenfelter air intake, and i took the cats off my exhaust and i need help to disable my 02 sensors

Rear O2 sensor disable

The 02 sensor group contains P code disable for 02 sensor related codes. Turn these off for long tubes.

NOTE: The rear 02 sensors must be plugged in for this to work.

===================================

you can also disable these, since you don't have CAT's anymore:

COT Protection

Catalytic Overtemp Protection (COT) is used to add fuel to cool down the catalytic converters and it should be disabled only when cats are removed.

* COT enable temp:
temperature when to enable the COT process, set this high(1200) to disable it.

* COT on/off:
switch to turn COT on or off, set this high to off to disable COT.

* COT time delay:
time delay for COT to kick in, raising this will delay the time it takes for COT kick in.

* P0420:
turn this off when turning COT off

* P0430:
turn this off when turning COT off

I thought DiabloSport wasn't allowed to include the turn offs anymore since the EPA is being stringent.

I hope its true, because I'm a strong proponent of keeping the car legal and all emissions equipment intact.

not sure if/when they started doing that yet...

it depends on when the predator was purchased and/or what revision it's on...

if it was recently purchased, it may not be able to... but the older ones still can...

and it can still be done with a custom tune...
