    Question about CMD unit

    Hey guys if I add the CMD unit to my 06 RXP after I add an external intercooler, I already have 42lb injectors, will I still need to add an RRFPR or with the CMD take care of everything for me?

    The cmd can take care of everything, but alot of guys like using it as a safety net just in case something goes wrong it will then rely on the rrfpr setting. It's your choice.

    I don't run a rrfpr on my ski and have used the cmd only to control fuel on modified engine with 3different ecus ( stock, riva + lescooke 9200) and with various superchargers (xcharger and rude2)

    As long as the 42 injectors at 100% duty cycle can handle the fuel requirements of your engine, then the cmd will manage it all very well. (and with your mods should be fine) If you decide to add more boost, then would need to up injector size.

    If you don't have one, add a afr gauge so you can dial in your fuel requirements.
