    rotax ecu ?? need to wait a bit 4 rude

    i have everthing i need for the rude set up..except enough cash 4 the charger itself. it might need to be up to another month i have sitting infront of me a rotax racing ecu', rude programmer, and the riva valve train, ...currently set up stage 2 w a P.O.S. vortech wheel from riva.... open stock box,, through hull ,,and riva intake with a getto intercooler ,,just like the xs... trimed bucket, fresh air intake scoops ,home built pro block offs,, and home built sponsons ,,as seen in profile pics ...unfortunately my ski only turns the 15/20r at about 75 to7600 rpm it us just to steep 4 the stage 2 i have been changing things so fast... i have only had the ski since july ...going as fast as my wallet will let me to stage 3+ ...WOULD I SEE A NOTICABLE DIFFERENCE if i bought a set of 42# injectors for now and installed my valve train stuff and ecu..or should i just keep the $200 and get the rude a bit faster

    u can put that Rotax Ecu on your ski with stock injectors with the little mods you have on there already...

    an intercooler, a vortech waste of time impeller, and an air intake? ... u'll be fine with stock injectors and the RR ECU... that used to be a pretty hot generic setup back in the day

    you arnt lying about waist of time vortech .8 psi.. that was an yes an as in 1 expensive hp.. thats why riva doesnt say how much boost it gives you.... well ..i have only had this stuff for a month i didnt think i could run that ecu on stock injectors. will i see more rpm you think i was a little upset when a stock rxt was side by side at top speed .. i had much better accelleration but less top end

    yup... the rotax racing ECU u can run on stock injectors no problem. before all the high boost options became available, we were all running around with RR ECUs on stock injectors with riva stage 2 kits with no problems. We have a customer where i work that has a Riva stage 2 with a Rotax ECU and stock injectors going on 3 years with no problems


    u'll see more rpm, but u still wont see enough rpms...i bet ur still short about the same about (+/- 400 rpms) ... and u'll gain a whole lot more acceleration with that ECU
