O2 sensor Dyno question
I would like to check my A/F ratio during my dyno but don't know how it is done. Can someone help me out on this?
I talked to the dyno shop who did the dyno for me last time, he said he has the wideband O2 sensor but he has to plug it into some part of a car and he has not idea where. This is a one-man shop and owner is a Honda guy, so he is not familiar with C5s. Can someone please tell me where to install this sensor? Thanks.

If he doesn't know than try to go elsewhere.
I know of two types of wideband that they can use, one goes into the exhaust outlet pipe (tailpipe) and the other is a threaded sensor (O2 5 wire) that is supposed to fit into a bung in the exhaust, around the collector of the header.
If he has the latter type, you need to drill a hole in the exhaust and weld in a bung.

Re: O2 sensor Dyno question (pkmoose)
I'm with Pat, if the dyno shop does not know where or how to install a wideband sensor, you don' t want to be there. To do it correctly, they will (or should) install two sensor bungs in the pipes and install two widebands to check the right to left A/F setup. If you don't have a heavy modded C5, then you can use one, but one at least is the key.
