'56' Mondeo ST 155 TDCI - does anybody know .....

[GSE]

.... if it's possible to get the on-board computer to show instantaneous mpg, can only get average at moment. Would like that feature I have it on my Monaro. Getting 39mpg average at the moment, a/b road cruise to work, 30 miles. Should they do more? Would like to see where the engine runs best in eco terms.

Also, is it possible to get the cruise control buttons on the steering wheel illuminated at night?
