Hondata

I want to use these input, I use to work like these on all the K-pro that i tune and never add a issue.

I connect the red wire analog 0 to the output 0 - 5v from the PLX, and the 2 black wires to the thermostat housing ground.

On the K-pro always work perfect with no issue what so ever but on the S300 isn't working.

What I need to do?

Make sure you are using the most recent version of software: https://www.hondata.com/software

I wasnt using the latest version but even with the latest version updated is not working. It seems to me that is going pick up information from the pin that we choose on the closed loop tab, it sould redirect to the analog in stead of the d10 or d12 etc...

From Help, About, what is the version of software you are currently using?

Post your calibration and datalog.
