Is it possible to wire a flex fuel sensor into a 2005 tsx running 07 ecu and flashpro?

You need a Flex fuel sensor and controller to use it.

ok just wanted to make sure it was compatible with the tsx ecu. I would just wire it to b22 or b12 correct? Or do i use the secondary fan switch?

You can use any of the inputs listed in the drop down in the Ethanol input section.

Is the controller just a PWM converter to give the factory ecu Voltage instead? Will a basic voltage converter work?

More or less they are frequency to voltage converters with a buffered output (not duty to voltage or 'voltage converter'). It has to cope with the error frequency. If you go this route it depends on how good you are with electronics and how much time you want to spend getting it to work.

What's the best pin to use with A71 Ecu? 2006 TSX Manual.

You can use any of the listed inputs when you have the calibration open and look at the flex fuel options.

Is there a controller you can recommend?
