LOL, how much you willing to pay ?
Only pectel, collins and MSD chips will produce the data stream provided
its enabled in the chip.
However its not a stricly a data stream.
You have to send it various commands that the ecu replies with data.
Also the P8 ecu needs a hardware mod to allow the interfce to work.
The interface on all version ECU's is non standard as is the low level byte protocol and serial baud rate.
