    Riva ECU fuel question

    Friend is finishing his rebuild on his engine and has riva 8500ecu and valve train and newX charger and riva IC. Question What injectors does he use I was thinking the riva ecu was maped for 50s or can he run stock with the rrfpr? which is safer???

    He should run the 50# injectors because that is what the riva ecu is mapped for. I would also run the rrfpr on top of that for colder conditions.. I ran into some leaning out issues in cold weather with almost the same setup.
