I have a test pipe coming in tomorrow and did not realize that the CEL fix was embedded into the test pipe. I have read that this design has not worked for many others so maybe this can be answered right away.

My s is in my garage taken apart, and I'm installed a vortech v3 with Haltech as the ems. I'm installing the wideband and going to obviously bypass the other two o2 sensors.


With this new test pipe and the odd embedded CEL fix, should I install the wideband o2 on the header where the old stock o2 was or can I install it on the new test pipe where the CEL fix is?

I am not sure how much the air to fuel ratio reading is effected with this type of "cel fix"

The wide band 02 goes up stream and is the primary, the o2 in the cat is more to check if the cat is working, you can just leave in your stock 02 and disable it with your haltech (it should have this feature)

if you were to put 2 wide bands and stick the wide band in to a CEL fix which is basically a fancy way of reducing the flow to the o2 sensor then your ecu or whatever is measuring the o2 would think that the engine is running too rich (too much fuel, not enough o2) and it would lean the crap out of your engine

Doesn't your wide band just replace the oem factory wide band with a more sensitive high resolution sensor?

I have the prosport evo wideband with bosch 02 sensor. After the information you gave me, I will leave the stock secondary in the test pipe and disable while installing the wideband into the header o2 location.

Thanks for info!
