Hondata

I've tested and confirmed that it is working with 2.7.5

Question: Is this in a running vehicle? Do you have good fuel flow through the sensor without bubbles?

Mega early holiday update: Case closed.

I replaced the sensor and everything is working as expected now. Ethanol content floating around 9% with normal pump gas. I'll be returning the original sensor.

Thank you all for the help, happy Thanksgiving!

Thanks for posting the resolution.
