As the title states, I need a personality file.   

Thanks for any help.  MQ12Di  

Also is there a user manual for Pi Cal Tool?   Is there a PDF for user manual for the MQ12Di?

A personality file is not directly linked to ecu's, personality files are for the operation of Caltool. Open access Developer personalities (PEXT in old Descprow terminology)  are available here on this forum,  Go to  Categories, Pi Caltool, Software Release.  Download the personality to the folder in Caltool sub directory. To install the personality you double click on the personality file you just downloaded.   Then open Caltool and connect to the ecu..    Being MQ12di this ecu could be an OE system which will have it's own Developer personality, ie Bentley from M-sport or otherwise..  In this case you would need to contact M-sport or the supplier..   Can you do as I suggested above and then post the message you get when you try to connect to the device.

cheers
