Hey guys, I'm new to the tuning scene (and milwaukee) and it looks like the rear O2 sensor is not reading ready. Does anyone know a quick fix to turn this on for a while to pass an emissions test besides using a tactrix cable and putting a stock tune on.

I got my current tune from Boomba Racing in Chicago 90 miles away and would rather avoid the trip twice.

 

Usually driving around more will work. Don't unplug the battery or clear codes. If you're throwing a code then you need to sort that out first.

 

Standard drive cycle is this: Start car, cruise on local roads about 5-10 min, get onto highway and keep steady speed above 50mph for at least 10 full min, get off of highway and drive on local roads about 5-10 min, park car and idle for a min, then shut down.

Car usually needs 2-3 drive cycles before all readiness tests will pass

 

I had put 160 miles on my car since i last did any work on it (oil change) when I went to go get it tested, mixed city and highway driving. Turns out the O2 sensor and heater were turned off in my tune.

 

lol, whoops

 

Rear O2 as in the one that attaches to the CAT? If so, you can get a spacer for around 25 bucks which will give some space and restricted air flow that can trick the sensor into thinking that your not tossing out whatever it is that is causing the code. Works has em in stock as of last week and your local tune shop may have them as well.
