The S8 will already run this if you are prepared to cut off the ecu plugs
and remake them.
This then allows mapping of ignition and boost only plus will
drive injectors if you fit them and dump the mechanical crap.

There WILL be an ERST truly plug and play ECU version by the end of the year.
This will be functionally and software identical to the existing S8.
