MPGuino only connects to one injector. If that injector shuts down during DOD, you'll get a zero reading. If that connector doesn't shut down, you'll get the same reading as an OBD scanner.
You'd need to build and Arduino that connects to every injector (or each independently controlled injector bank/ pair depending on how the DOD system is set up) and sends the averaged signal to an MPGuino.
If there's a 'fuel economy' signal in the loom, MPGuino can be used to tap directly into that. Most modern European cars have that signal available at the instrument cluster, even if they didn't come with the display stock.
