    Fzr big problem help me

    Hi guys, I have a big problem on an fzr sho. After installing C5 Supercharger , intercooler plus cooling , air filter, Tial ,retainers kit, pump 160 , ECU R4 ,and and pressure regulator but, my ski has serious problems. With ecu R & D my idle continues to be inregolare 1330/1100, my afr 11, if I accelerate fast my motor hole. With the stock ecu I have the same problem but if I disconnect the map sensor on my engine gets a tiger, my idle is perfect and the motor does not pit anymore, but I can't test it in water because it would be too thin. I connected the diagnosis but does not detect any problems. you have something to suggest? Thank you

    That surging idle with both ecus that goes away only when you unhook the Map sounds more like a leak.Pressure test the motor and try to only make one change at a time when diagnosing

    [Quote = FXSlowKroozer; 2784392] Questo aumento di inattività sia con ECU che va via solo quando si sganciare la mappa suona più come un test leak.Pressure il motore e cercare di fare solo un cambiamento nel momento in cui la diagnosi [/ quote] thanks for answere, but my question is: Why with stock ecu with air pressure disconnect engine is perfect? And with stock ECU and sensor connect engine running bad?.

    Check your vacuum lines. The one to the MAP sensor and the ones to the fuel pressure regulator (if it has one) and blow off valve.
