I am throwing the Catalyst CEL b/c of the test pipe and I am looking to getting a O2 Simulator but I was wondering which one is the best and where can I get one? I know the 3-wire units dont work ...but what about the 5-wire ? Any suggestions ????

 

Nobody on here is running a test pipe?

 

If you can find a 5-wire, they work. The one I have is an ECG 5-wire unit from LakeEffectPerformance (Out of business). I tried a 3 wire from Caspers, but it didn't work for more than a couple driving cycles.

 

I appreciate the reply back ..... thanks

 

is it 4 wires that are needed or 5?...i see a o2 similator for sale that has 4 wires...will that work?

 

Try www.wiredspeed.com They sell the ECG/Ziptech O2simulator.

 

I have a new brand O2 Simulator which is going on my car today with a test pipe. I'll let you guys know how it works next week.

Are there any gains in using a test pipe with stock exhaust?

 

I gained several rwhp after adding my testpipe (stock exhaust). However, when I borrowed a J's single exhaust, it actually lost power. I think the test pipe may work best with stock exhaust.
