Dummy O2

If I get jethot lt's, will I need the dummy O2 sensors for the rear? Will not having them just set off a code, or will it affect performance? I assume I can have them programmed out along with the EGR and AIR.

assuming you have the dual cat car, yes, you need o2 sims, it will affect performance, and they can be programmed out. mine were. i have some o2 sims for sale if your interested. i used them about 2 or 3 months before i got programming. email me at markacpa@tiagris.com

i don't think running with out sims hurts performance you just get a SES light.

running without the rear o2s, will get a ses light, but no perf decrease...

front o2s will give u bad mileage if they're bad... and they're ignored on WOT anyways (PCM has a table of its own for WOT)

You can have them programmed out with the air pump and egr... Why buy o2 sims if your gonna have the air and egr programmed out too... Wont cost you anymore to have those codes deleted out of the pcm.


Contact ION (madwolf) off the board. He does good programming and will work with you so that your a happy customer.
