O2 sensor, working on full 3"

[gerbot_3000]

does going 3" all the way from the turbo to the back of the car without muffler or catalitic converter or anything affects the O2 sensor readings? since the gases are passing so fast? or obviously different?


thanks a lot

That is a good question.
Connect your voltmeter to the signal line and ground,if the voltage is crossing above and below .450 volts at a good rate and stays between .250 and .750 when it crosses you are good.I fit lingers at the low or high end .100 or.900 or is not crossing that is a problem.

is the O2 in the stock swing valve? If so it should be just fine. Are you running a stock cal? On old cars with carbs when we use to open up the exhaust we would have to richen up the mixture because a free flowing exhaust would let it go leaner. The fuel injected cars when in open loop run on a program sorta. When I put on my 3 inch system I noticed it seemed a little lean on cold start up but as soon as the O2 comes on line all is good. It takes less then a minute on my R/T.
