5 wire wide band sensor
Turbo Mini Forums

Hi all,

It appears that I have gone and got the wrong wide band sensor after damaging mine. The repacement is a 5 wire can I just swap the plug over?

I can use my techedge kit to re-calibrate the sensor, so just wondering if this will work..

Any ideas

Thanks all

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

That will be a no for anyone finding this post later in life. The sensors are calibrated with a little doofer in the plug...

Id suspect the sensor is the same so if unlike the Vems guage, yours only uses five of the six wires nomaly associated with them and have to carry out a free air calibration routine, you might get away with it but which wire is which? Are they the same for the 'six' wire the only difference being te cal resistor connector. Its not a techicality i am familiar with since you neednt think about it if you use the right sensor in the first instance

My TechEdges use all 6 wires from the controller to the plug.
The "little doofer" is a laser etched resistor inside the plug, etched to a specific value after the plug/sensor combination is calibrated at the factory on a specific gas.

So I guess, without it, you might get the free air calibration right, but you really want the 10-14 calibration right, not off scale lean.

There is a lot of information on the 14point7 website as to why the factory sensor calibration (on a specific "rich" calibration gas) is so much more important than "free air" calibrations on an installed system.

Schrödinger's cat - so which one am I ???

Well I have ditched it for a new correct sensor
