It could be from anything. You will have to check for leaks and fix whatever it is leaking.

Do you have on-board datalogging enabled?

Do not use D14 for wideband input, as it cannot see the full voltage range. Use D10 instead: http://www.hondata.com/help/smanager/wi ... b=wideband

With everything plugged in and the ignition in the on position, go to the Help menu and click on “send feedback”. Include a detailed description of the issue.

It could be the wideband or there could be a fuel system issue.

Have you read the info in the help file: http://www.hondata.com/help/smanager/an ... sub=analog

Are you sure it is seated on the pins properly?

Have the capacitors been replaced in the ECU?

Have you tried your ECU in a known working vehicle?

You never mentioned what vehicle this is in.

If the ECU is damaged it will have to be replaced. You may have a dealer that can do K-Pro installs near you than can take care of this for you: https://www.hondata.com/us-dealers

Your battery voltage appears to be low, I would recommend that you try charging the battery before doing anything further.

Do not disconnect the battery.

Hold the start button and it should do something.

Please send the feedback info as requested.

With everything plugged in and the ignition in the on position, go to the Help menu and click on “send feedback”. Include a detailed description of the issue.

Unplug from the laptop and the vehicle, then close and reopen the software and only plug in the USB. It should prompt to update the firmware. Let this finish, then plug into the vehicle.

Your software is out of date. You need to download the most recent version and then upload to the ECU.

You need to try swapping the K-Pros to see where the issue is.
