Lambda sensor wiring
I've got a wideband lambda sensor as part of my power commander V autotune set up
but the wiring is a little bit on the short side from the sensor.. would it be ok to cut/extend the wires or would it effect the readings?
here's a piccy of the sensor the multiplug plugs into a longer loom but it would mean having the big plug outside the car :/

The plug on the sensor may be more than it seems, they tend to have a sensor built into the plug, I guess it measures fresh air so you really need to
piece out on the loom side, not the sensor side.

Hey Mark, i've still got your Cortina hubs if you ever need/want them
What i wanted to do is cut the wires between the sensor and that miltiplug and add a section about 12" just so it can be extended it will be as
it is but longer with a couple joints for the extra wire length
or would that mess up the readings/calibration

The plug on a normal wideband probe does not contain a sensor but has a calibration resister in it.
I have extended by a small length the looms on a couple of probes I have fitted and never had a problem. To check it or when calibrating it if needed,
you can do a free air test. Just google "lambda free air test" for lots of info on how to do this. Unfortunately I have not used a power
commander so I'm not familiar with the software!
Hope that helps, Si.

Ok Si thanks
i've done a bit of googling and looks like you can buy extentions that plug in, so cutting the loom should have the same effect i guess,
i've also emailed a company that sells them for afr gauges to see what they think
not had much luck speaking to anyone at dynojet :/
