ya, i switched that on the tune i made after my last post...
just pulled the P0420 codes out of it again today
Im thinking the switching isnt actualy doing what its supposed to.
possibly time for the EFI guys to check their code.

oops, heres the latest tune
does anyone from EFI actually read these forums for customer feedback?
Well Im stumped man, Ive heard of people killing the CAT DTCs on I6s before so this is puzzling. Im still catted as I pretty much have to be in WA, so I cant go run and test it.
EFILive does monitor the forums pretty regularly, just the P10s are GMs little bastard child and Im happy we actually have a way to tune them. I do have a wish list but the code is supposedly really hard to crack.
Its hard to narrow down if its a mis-labeled switch as another member suggested, although the thought has crossed my mind, as it doesnt come up right away. Sometimes its taken a couple of days and several runs for it to show up.
I am going to try an o2 sensor spacer when it arrives......this is supposed to take the back o2 out of the stream a little.....
In the Audi circle, people use spark plug defoulers(only on the post cat sensor) in order to trick the ECU when running a test pipe in place of the catalytic converter.think you have to drill the hole bigger on a defouler

let me know how it works out.
Last time i cleared the P0420 code it went allmost a week before popping up again. The wife said she was flogging it pretty hard when it came up this time.
This has me thinking if its related to the cat protection somehow....possibly the sensor is getting hotter than the computer thinks it should??
My next step actually was going to be to just clamp the sensor off to the side of the exhaust pipe or the hanger and see if that helped.
it has to be in the stream...already tried disconnecting it or hanging it to outside air connected
Before having all the codes disabled in efilive i used one of the bungs they sell on ebay,

they worked great, here's the list of codes i have disabled and NEVER got a code back, NEVER...
>>>>> P0137
>>>>> P0138
>>>>> P0140
>>>>> P0141
>>>>> P2A01
>>>>> P0420
>>>>> P0054
this disables all the monitoring of the 2nd o2 sensor,
same thing but the place I ordered it from hasnt delivered...so maybe ebay is the way...bought th efans and pigtails from there
