Magnum 360 fuel inj.

Need some help with a magnum 360 late model with the Mopar Performance package and emission exempt computer. The question is what do I do with the down stream 02 sensor? I am not using a cat converter.  

sure way would be to just grab a cat off a 360ci equipped truck/jeep/van and run that so you don't get any codes. if you aren't hooking up the gauges you don't really need to do anything though, since it only throws a 'soft' code. it doesn't cut power or anything. it just notifies the user that the cat is not as efficient as the system standards require.

The other way is to zip tie it to the frame making sure the element can't melt anything. Or buy a cat-delete sensor that plugs into the harness.  They haven't had the best luck with those on the R/T's though from what I read on the board.  

O2 simulators are used greatly in the import scene...    all the downstream O2 does is calc the efficiency of the cats...   it does not meter fuel mapping so it is easy for them to be simmed...
