Ok i got a quick question for you guys..
Im fixin to order a Eaton LSD and 4.10s..
but while im recovering from that and saving up for the LT headers and ORY pipe, could i gut my cats and turn my rear O2's off with EFI Live and pick up any power with the stock manifolds??? I have replaced my stock muffler with a 6"Rd magna flow.

If so where do i go in EFI Live to turn them off at?
and is there anything else i need to change?
Thanks Guys!!!

 

you can turn off the rear o2's but its not going to get any power what so ever... only thing the rear ones do is check to make sure the cat is working right

 

even if i gut the cats? just wondering

 

im sorry i think that i missread your post... you will gain some power by gutting the cats..... makes it flow better but in all honesty your stockers flow good not sure if you will notice the power that you will gain

 

ok.. i wont worry bout it then.. ill wait for the LTs and ORY. Thanks LesPaul!!

But ill still need to turn off the Rear O2s when i get the LTs...
How do i do that with EFI Live???

 

i dont have any idea how to turn them off in efi live i dont use it

 

A couple things to change:

Engine Calibration -> Cat Converter -> Catalytic Converter Protection Enable: {Disable}

Engine Diagnostics -> Engine DTC Processing Enablers -> P0137 "O2S Circuit Low Voltage Bank 1 Sensor 2": {X: Not Reported}
Engine Diagnostics -> Engine DTC Processing Enablers -> P0138 "O2S Circuit High Voltage Bank 1 Sensor 2": {X: Not Reported}
Engine Diagnostics -> Engine DTC Processing Enablers -> P0140 "Circuit Insufficiency Activity Bank 1 Sensor 2": {X: Not Reported}
Engine Diagnostics -> Engine DTC Processing Enablers -> P0141 "O2S Heater Performance Bank 1 Sensor 2": {X: Not Reported}

Engine Diagnostics -> Engine DTC Processing Enablers -> P0157 "O2S Circuit Low Voltage Bank 2 Sensor 2": {X: Not Reported}
Engine Diagnostics -> Engine DTC Processing Enablers -> P0158 "O2S Circuit High Voltage Bank 2 Sensor 2": {X: Not Reported}
Engine Diagnostics -> Engine DTC Processing Enablers -> P0160 "Circuit Insufficiency Activity Bank 2 Sensor 2": {X: Not Reported}
Engine Diagnostics -> Engine DTC Processing Enablers -> P0161 "O2S Heater Performance Bank 2 Sensor 2": {X: Not Reported}

Engine Diagnostics -> Engine DTC Mil Enablers -> P0157 "O2S Circuit Low Voltage Bank 1 Sensor 2": {No Mil}
Engine Diagnostics -> Engine DTC Mil Enablers -> P0158 "O2S Circuit High Voltage Bank 1 Sensor 2": {No Mil}
Engine Diagnostics -> Engine DTC Mil Enablers -> P0160 "Circuit Insufficiency Activity Bank 1 Sensor 2": {No Mil}
Engine Diagnostics -> Engine DTC Mil Enablers -> P0161 "O2S Heater Performance Bank 1 Sensor 2": {No Mil}

Engine Diagnostics -> Engine DTC Mil Enablers -> P0157 "O2S Circuit Low Voltage Bank 2 Sensor 2": {No Mil}
Engine Diagnostics -> Engine DTC Mil Enablers -> P0158 "O2S Circuit High Voltage Bank 2 Sensor 2": {No Mil}
Engine Diagnostics -> Engine DTC Mil Enablers -> P0160 "Circuit Insufficiency Activity Bank 2 Sensor 2": {No Mil}
Engine Diagnostics -> Engine DTC Mil Enablers -> P0161 "O2S Heater Performance Bank 2 Sensor 2": {No Mil}

 

nope, gutting the cats with stock manifolds will not make a noticeable difference.

 

Thanks Thunder, DLH2006, and LesPaul..... i got that saved now...

So basically all that does is.... it wont read the rear 02s and then disable the MILs so the SES light wont come on??

 

The O2's will still report to the PCM but it won't do anything based on what it reads from them, meaning that it won't set a DTC or SES light if the readings aren't what it is expecting.
