If you modified a tune without knowing what you're doing, don't label that as a KTuner issue and especially not a KTuner Hardware Failure. Simply not accurate. If you had two tunes to choose from when you started a basemap you likely chose the wrong one to start with because you simply didn't follow...

Unfortunately whatever issue you're suffering here is beyond what we can assist with. If you can connect to the unit without the vehicle connected or on then you should be able to connect to the unit with the vehicle in accessory mode as well.

That was the original usage. Unfortunately the CAN Gateway that's been added on all more recent model years will prevent this data from reaching the OBD port.

As the locking/unlocking help section indicates returning to factory on a V2 is done on the unit.

It's listed as supported on the website, as you noted.

Returning to factory is the factory tune. Starting a new tune is a tune starting point.

See the tuning table pull down menu. If not familiar with the tuning table see the help section which outlines the items in a layout.

You can only disable IACV using the PRB/RSX codebase, so I'll assume you're using that. An RAD ECU does not have a check engine light output, so are you manually checking for error codes anyway? Is the TPS reading zero when closed and idling?

What Accord ECU? What codebase are you flashing? If you're not seeing error codes for the IACV when disconnected that makes me think it's disabled or you're on the wrong codebase. TPS needs to read less than .5 in order to go into idle mode.

You're welcome.
