Zeitronix wideband/ linear or non linear output
Hey people, I'm wiring up my MS. I'm not sure what wide band output to use from the Zeitronix. There is a linear and a non-linear output. Apparently the the non-linear or analog output, as it is labelled on the wiring diagram on the ZT instructions, is the original output on the ZT. The linear output was an addition to the ZT on newer models. I'm just not sure which one to use. I looked in the Megatune software for wideband options and there is only one ZT option. How can the MS differentiate between the two? I searched this topic and most said the analog or non-linear is what I need, but most of the posts were quite a few years old, anybody know which one I should use. Thanks Dan
Re: Zeitronix wideband/ linear or non linear output
I have used both. The non-linear one is actually a wideband but just has a mapping that is not linear. It happens to be the natural curve of the sensor. Megatune has the curve/function built in as does megalogviewer. You can see both mappings in the directions for the zeitronix. If you use the 0-5 volt output, you will need to enter the afr mapping function so I recomend using the non-linear wideband output. I'm pretty sure it needs to be set in the configurator under car1, settings.ini, lamda sensor. Select zeitronix non-linear. In megalogviewer, Calculated fields, Zeitronix.
