I installed my mpguino, its hooked up to speedometer wire and fuel injector wire. I have it on the instrument screen, It doesn't give any values. I'm pretty confident that I have both connected correctly along with power and ground but its not giving any values and it just sits there and flashes the "I". What am I doing wrong, also I have peak hold, followed instructions given by
MPGuino Fuel Mileage Meter
I don't understand whats wrong, please help
Thanks, Matt
