    What should i do next to my 2012 RXP-X 260 Please ?

    Hello Guy's ,
    I will start with what i have already done to my RXP:
    Les Cooke C kit supercharger,
    Les Cooke 60lbs injectors,
    Les Cooke remapped standard ECU 8800 RPM,
    Les Cooke 4' intake with flame arrestor and air box removed,
    Walbro 255 fuel pump with fuel pressure regulator but not running rising rate as per Les instructions base pressure set @ 60psi,
    Ported head,
    Lightened cam sprocket,
    629 cam set to give cylinder pressure of 135 psi,
    Supertech light weight valve set,
    Supertech Sea-Doo specific dual valve springs but with Les Cooke titanium retainers rather than the Supertech ones,
    ARP head stud set,
    Rad4 Racing torque plate taped and plugged ready for exhaust temp probes at some point,
    Exhaust manifold taped and plugged ready for lamda sensor,
    Block guard,
    Riva waterbox,
    Full Riva though hull exhaust system,
    Custom made intercooler made from Pace 500 BHP core with pressure bypass built in to it,
    NGK DCPR8EIX Iridium Spark plugs,
    Stainless steel wear ring,
    I have lots of props i think i am running a Solas SRX-CD-15/22R at the moment,
    R&D pump seal,
    R&D Aquavein intake grate,
    160 degrees thermostat,
    I want to keep it closed cooled because of salt water use,

    I have some money saved and want to do my next stage but not sure what to do ?,
    So before i make my order with Jerry i wanted to know what you guys thought good or bad " I can take it lol" on what i have already done please and your thoughts on my shopping list and what you would buy and do next please,
    I am a engineer and not frightened to learn and maybe but hopefully not make mistakes along the way,
    I want to buy things that will be able to work with any more upgrades i do in the future,
    My idea is to one day have the most powerful none turbo ski i can build so my next shopping list should be able to cope with future tunning as much as possible rather than cost now,
    My thoughts are:
    Riva Athena or Riva Vi-PEC is the latter worth the extra money ?,RS11890-ECU-DC
    Riva dash logger is it worth having or do i need it ?,RY11841-LD-MD60
    Riva dash logger cable,RS11850-MD60-EC-11
    Rive dual map switch,RY11841-DMS-ECU-DC
    Riva lamda kit,RY11540-LC1-6S5-1
    Engine Tech billet water cooler,ET Water cooler 2
    Riva air intake kit RS13110,RS13110-CAUK
    Turbo Tech billet fuel rail,tt fuel rail
    Riva high flow fuel filter,RY12040-BFF
    Rotax cam chain tensioner,4222, I have had the head skimmed but the standard tensioner seams okay ?,

    There are so many fuel injectors i dont know which ones to buy to suit the Riva ECU and and any future tunning i will do , I want to avoid buying anything i will have to upgrade again if possible please,
    I dont know anything about pump,prop,nozzles,wedges,cones so any input on that side would be great thanks,
    I use my ski 90% in the sea for wave jumping so top speed runs are hard to do anyways but i high top speed would be nice lol , but mainly hole shot and bottom end grunt,

    The things i have listed above is about all my budget will go to at the moment but my next shopping list after that will maybe be:
    Engine Tech ET 70-145 race edition supercharger light edition, ET 70-145 Race edition S/C LE
    Rotax heavy duty supercharger shaft, can not see it on PWC Performance at the moment but hope you know what i am talking about
    Lightened balancer shaft,
    Lightened flywheel,
    Carbon fiber hull lol ? one day maybe ,

    Thanks very much for reading and any input you guy's have would be greatly appreciated,
    Cheers,
    Waz

    Skip the Vipec and the Athena and go MoTeC.

    Motec customer support is second to none. I've witnessed it here on the forum. I'm sure Nils will chime in, he's the motec MAN!

    Go motec if you want the best stand alone ecu. I personally run vtech and a CMD and am very happy,my vids and mods are in my sig.

    With the money you have put in this so far it would be stupid to run anything but Motec .

    Thats a ton of mods!
    Has to be a ton of fun!

    If you go motec talk to nils he is the man.
    Setup really is pretty easy. And usually only takes 1-2 tuning rides to get it dialed in if nils helps you.

    If you want to spend some coin get a 16 or 18 vein rotax racing pump and nozzle!

    Dual scat prop.

    Lucky 13 pump cone setup.

    The list of possible parts is almost endless.

    All you need is the Motec M130, LTC (lambda to CAN) for AFR logging, and Injectior Dynamics 1000cc injectors.

    It comes with the M1 software which is endlessly modifiable and i2 logging software.

    The base tune that we are using now will work great with no changes required.

    I guarantee you will love this setup!!
