    What is the most straightforward way to add 8 O2 sensors to the Dynomite dyno. I’m thinking that it might be cool to have them in place of the EGT readouts on the Console view is that possible to do?

    If you have. 28 channel Pro board and Pro software. The swap over from EGT’s is a simple electronics channel switch over. Look in your EGT channels and you will see a tab that indicates EGT MV or 0-5

    You could also use 8 Innovate LC-2 Widebands via Serial to USB on a USB hub.

    Something like this – https://www.amazon.co.uk/StarTech-com-USB-Serial-Adapter-Hub/dp/B009AT5TB2

    There is a DAQ file available on here

    In Dynomax “Calibrate Dynomite Channels” inside of the tab for each EGT sensor channel there is a button where it says, “ALL EGT’s in mVolt” and another with 5 volt.

    Then what I would need is a sensor setup which would produce a 0-5 volt signal for each sensor is that correct?

    You would select Custom on the drop down list. This will allow you to set an AFR and 0v and 5v or whatever your Wideband is going to output.

    The disadvantage of doing it this way over using the innovate serial stream is the widebands are typically very sensitive to ground offsets. You would want to confirm the readings and keep an eye on the trends as I’ve seen them swing away.
