    Question about ECU for 42# injectors

    On my conversion ski, I would like to know if I should upgrade my stock 215 ECU to accomodate 42# injectors. My motor is a stock 08 RXP 215 with 42# injectors plus an X charger and external intercooler. If it is ok to keep the stock ECU, I want to keep it and not upgrade. I do not want to increase the rpms.

    It runs fine right now, but a little rich. If I need to change, what should I do?

    Thanks for sharing your experience!

    No need to change your ECU. I would suggest adding a rrfpr. That way you can tune your fueling needs.
