Does the Predator Ignore the second O2 sensor?

[Quick]

You wouldn't care if it doesn't work if you've removed your cats. If you haven't removed your cats then it can tell you when they aren't working rather than finding out at an inspection or just before when and if you restore the stock tune. There is the slim chance of just getting stopped and checked for illegal mods. They did that once outside of Infineon raceway. They set up a vehicle checkpoint after the evening drag races and were busting people for non-approved mods.

is there any way to add this to the next revision of the standard 93 oct. tune? it can't hurt anything....

Can't hurt anything? Its an instant failure of an OBD2 inspection. Many of us need to pass that to keep our cars on the road.

but normally if you take your car to dealer for inspection or for emissions inpection one should flash there car back to stock anyways, no? and put the factory exhuast system back to stock.

just zip tie it out of the way... easy and replaceable

c'mon apex, don't i get enough of you on ptcrew?

(only kidding)

i thought we had come to the conclusion that without Stage 1, the zip-tie trick doesn't work.

i have 2 spark plug anti foulers in place. when i first started the car i had a check engine light. i drove it an hour or so that night. the next morning, the engine light was off and it hasn't come back on. so i guess the trick is working.

you can't get away from me... i'm everywhere.

the antifouler will work but it'll take some testing and adjusting to get it right... sounds like you got it...

the comp looks for a difference in signal between the upstream and the downstream sensors... so by zip tying the d/s sensor into fresh air, it'll think your cat is working perfectly...

which is basically what you're doing with the anti foulers... just getting the sensor out of the way enough that it doesn't read nearly as accurately as it would otherwise be...

[Letxen3]

is it bad to have the downstream sensor connected with out a cat?

Nahhh

+1 for the non-fouler mod. been running for over 2 years/10k miles (05 n-srt4 stock pcm) and have never thrown a code...
