Which Wbs Are Compatiable With Datalogit?

PLX M-300 is my current one. Since it has it's own LED readout, you can calibrate the DATALOGIT reading to match it. It is not expensive. http://www.plxdevices.com/index.htm
The M&W UEGO is also good but very expensive. I am part owner in one of these. http://www.mwignitions.com/software.htm
Whatever to get, make sure it has it's own display that you can calibrate the DATALOGIC to as the DATALOGIT reads and diplays leaner than what most widebands actually read.

Theoretically any wideband with a 0-5 volt output. However, I recommend purchasing a unit with the following two features as well:
(1) Linear Output:
The voltage output on most widebands does not progress in a linear fashion as the AFR increases. This can be compensated for using a polynomial equation in the Datalogit. However, I have heard there are limits to this solution, and many wideband manufacturers do not supply an accurate equation so the end user is left to derive it. Tech Edge and a couple other companies offer widebands with linear output signalsl, eliminating the need to covert the signal with the datalogit.
(2) Reference Ground signal:
The datalogit has a floating ground, which makes it difficult to get an accurate reading with a simple 0-5v wire input. Widebands, such as the Tech Edge line, have a reference ground wire that you can plug into the datalogit along side the 0-5v input line. Using the Delta function (AN1-AN2) in the Datalogit software you can record the 0-5v signal relative to the ground signal.
