I've got a Diablosport Predator sooooo... Quick question:

Should I go with replacement O2 sensors or just turn the O2s off via the Predator?


Much appreciated.

Oh, TJ (sitting beside me) says to type "Genetalia..." so I did.

O2 sensors are what "fine tunes" the fuel enrichment for your car. It is done via a combination af MAF > TPS > Manifold Vacuum > Engine Temp> and the exhaust O2 reading. If i were you I would not consider "turning it off" unless you plan to have it Dyno tuned to compensate fo the loss of that sensor. MIL eliminators close loop the O2 sensors to elliminate a specific engine code.

PS I would reply to Genetalia.....but it would not be pretty

the other thing does the same thing as the preditor. and there are two sets of o2 sensors on the car and all the diablo can do is turn off the back ones, and thoes arnt as important as the front ones. so no it want hurt the car to turn off the rear ones.

o2 sensors either add or remove fuel based on a number of variables you got some of them - other variables in the o5 o6 are: load, engine coolant,cylindar head temp, & RPM. I have my back ones turned off - it actually runs better with out them on. And any of the codes can simply be turned off (weather or not you are using the 02 sensor )

Okay, so here's what I've gathered from this (correct me if I'm wrong)

1: Turn off my O2s via Diablosport. This will eliminate the rear O2s.
2: Replace X Pipe and front O2 sensors
3: Set off car alarms with new, free flow exhaust.


But here's where I'm iffy: Do I need to replace my O2s if I simply don't care about the MIL?
