hi guys

I need to be able to transfer a hex file, via K-Line, to an ECU, now all I need is the ability to transmit via K-Line from the arduino

does anyone know how you can do this?

thanks!

This

or any other ELM327 based products should be able to communicate over a K-Line bus (ISO 14230).

so, that interface looks perfect, can I just send it commends from arduino for it to send in HEX to the ecu?

AFAIK this depends on the car and the ECU used. If your car supports it, you should be able to do that or at least send it in HEX to the ELM and the chip is responsible to send it to the ECU in the correct format.
