I wasn't aware that there was such a program in existence at all.
It also begs the question as to which Digifant? Last I checked,
there were no less than a dozen ECUs labelled Digifant.

I too would be interested in such information.

Re the injectors (?); you may well find that the duty cycle would be
too short for a stable idle. (Can you tell us what other changes
you've made and the base engine?) A second set of 240s would provide you
with better controllability - and if you are able to reprogram the
ECU, you may be able to use one of the "spare" I/O (with an external
injector driver for the supplementary set).
