    Mini rude for x model

    Hey guys, whats required to be changed to run the mini rude on an rxpx. Can you just run it with stock injectors and RRFPR or just with the 50# injectors?? or do you need both?
    There is no need to reflash the stock ECU either is there?
    Thankyou

    From what I read.... I believe if you run a rrfpr you can use your stock injectors and set the rrfpr at 60psi... Or 50lbs injectors but you would be really rich at the bottom end but fine WOT... You could reflash your ecu and get it mapped to your ski's setup...

    I will install the minirude and the 50 lbs injectors next week.
    Already put the mcmaster washers and minirude upgrade on my x-charger.
    I am busy installing the afr sensor on the exhaust manifold so i will be good to go very soon.
    Will measure my afr at idle ,mid and wot.
    Just curious how my afr's will be,i live in the Netherlands its a bit colder now,so my afr will be different from other people living in warmer climats.
    I am sure i will be on the limiter,i'm already turning 8160-80 with the mods i have.
    Next thing will be the riva pro series ecu ,specially mapped for the 50 lbs injectors.
    But first i will test the stock ecu setup.
    Because i will be adding the riva ecu,i won't bend my prop to get off the limiter,otherwise after installing the ecu i will be bending the otherway up.
    I will post the results soon.

    I think with the cold weather you may well need more than 50s.

    I would prob add a RRFPR so that you can lower the idle and clean it up a bit and it will give the extra fuel uptop. R88

    I was thinking the colder the weather the leaner the afr had to be... I was thinking more of running 48lbs with stock fuel pressure..

    I have my doubts to,we live in the same climate.
    But testing is the way to go,i will hook up my lm-1 and monitor my afr ratios.
    If needed i will go rrfpr,but first mod will be the riva pro ecu,because this ecu is mapped for the 50's,might need the rrfpr for the higher rpm's.
    But first just the mini and the 50's ,so lets wait and see the results.
    Thanks for the input.

    The colder the weather the leaner the afr gets,you will need bigger injectors,the warmer it gets the smaller the injectors.
    But a rrfpr will be a big help when weather changes.
    Lean is not good when running wot,you will blow up your engine.
    Lean at idle is fine.
