    Cool I need help with tuning RXP-X260

    I have a lightened 629 cam, Torx Racing ECU 9000rpm, Valve Spring & Retainer Kit Air Filter Kit
    Also think and overlay an ET 68-140
    But wondering if I should resort to RRFPR, larger fuel injectors and secure lot more but I'm a bit new to the game
    So nice if someone could a little more about tuning can make any suggestions

    You need everything listed and more.
    First I would start reading like crazy here, also find someone near you to help.

    Rrfpr
    Bigger injectors would be ideal but won't work with your ecu
    Better intercooler
    AFR gauge and preferably a way to log

    You will be well past efficiency range (duty cycle) with stock ones. Go with the Riva gen 3 intercooler

    Vtechtuned is only across the mountain ridge from you in Sweden.

    You really need to log your tune. Look on greenhulk performance store for the "logger" kit from vtechtuned.
    www.youTUNEit.net

    Your injectors are near maximum on 3 bar pressure 8600 rpm.
    If you run 4 bar, maybe you get lucky to 8900 rpm.

    If I was tuning this ski I would use:
    -Maptuner from vtechtuned www.youTUNEit.net
    -Logger from vtechtuned
    -4.2 bosch AFR sensor in exhaust
    -RRFPR set to 3 bar
    -1100 cc injectors from vtechtuned

    This way you can edit and make your tune perfect.

    Otherwise if you try tuning this ecu you have with just RRFPR, the ski might run funny with stock injectors and such high fuel pressures for 4.5 bar (rising rate absolute). You may also find you use a lot of fuel for no reason in certain parts of the map.

    Hi yes it is true has already sent the ECU to torx but may as well go for V-Tech, I also need to buy tuning Credit in addition?

    where do you recommend that I buy Bosch 4.2 AFR sensor in exhaust
    So tuning of ECU (9000rpm) us Torx Racing is not to recommend
