Transforming a Channel

Transforming a Channel

Most scalars that come from external inputs can be transformed into other values.


This can be useful for:

Transforming MPVI interface A/D voltage into Equivalence Ratio, Air/Fuel Ratio, Temperature, Pressure, ...

Transforming a Serial input Equivalence Ratio into an Air/Fuel ratio

Transforming a raw external input value into a parameter value



Bringing up the Transform menu

On the Channel display, you can right click a channel to bring up the menu. If the channel supports transformation, you will see an option called "Transform".


Channels Transform



Selecting your Transform

The Transform Selector form will show you any transforms that apply to the channel you have selected.


For example, if your base channel is a voltage input, the Transform Selector will show you transforms that take voltage as the input.

Defining your own Transform

If your sensor is not defined in our list, or you must account for a signal/noise offset, you can define your own transform.


In this example, I first selected Ballenger - AFR500, then clicked the Fx to copy it down into the User Defined area. This gives me a starting point close to my input sensor. Then, you can add any offsets needed for your specific installation.


You must select a parameter and units. The transform will convert the input source into an output of type of the parameter you selected, with the associated units. When adding this transform into your layout displays, you simply add the Parameter you've transformed your input to.


The user transform values you input will be stored with the channel, and will be saved any time you save your channel config.


User Defined Transform



If your transform is not listed in our default list, we'd like to add it for you. Please e-mail our support department and we can add it to a future build.
