Have you tried inverting the output?

You can calibrate it when you have the calibration open, and you datalog. It will allow you to read open and closed. Reupload to the ECU, Make sure you save a cop of your calibration to the hard drive.

You will have to post a picture showing what you are describing.

What was it doing before you tried using the FlashPro?

really hard to tell based on the limited info.

This is definitely something you should discuss with your tuner.

Have you discussed this issue with your tuner?

Post your calibration as well a datalog showing the issue.

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.

What wideband are you using and how do you have it connected?

Did you upload your calibration to the ECU after the firmware was updated?

The s300 will work in an automatic ECU, but it will not operate an automatic transmission vehicle.

You will need the standard K-Pro: https://www.hondata.com/products/kpro/kpro-product

There may be in the future.

You'll have to look at more than just the pins at the ECU as there could be a short somewhere in the harness.
