Stuck at 8,000 RPM"S. ??????????

[4-techscharger]

My ski is stuck at 8,000 RPM'S??????

I already checked the oil, Changed my super charger clutch, changed sparkplugs, cheked the pump area.......

I have the following mods

RR stock clsass ECU
RR Thermostat
RR Intercooler
Supercharger Impeller
14/19 prop
reverse bucket mod & waterbox mod
Pro series block off
Riva rear exhaust

I should be at 8350 RPM'S with about 74-75MPH but im stuck at 8,000 with 71 MPH which is below the stock ecu from seadoo

What else can it be

When i put the key in it has one long beep then normal beeps after (key is on)

Can the long beep be a senor problem? I already did the noc sensor

Please Help?????????

must check the following :
-check the wear-ring
-check the impeller (if not 14/19R , i heard 14/19 had many deflects (also mine .must check)
-intercooler plumbing
-clutch slip movement should b around 10newtons
-change sparkplug to colder# (ixu27)

no problem with that long beep .when u go to the dealer ,they can recode ur key for u

may b i would b wrong , but this is from my experienced.
good luck .

You might want to try a 15/20R. This an RXP?

I will try the Prop, but im having a problem when i put the key in I get a really long beep, like 5-6 seconds then two short beeps.... i think thats whats holding my RPM's back, but I will check into it

ANY OTHER SOLUTIONS PLEASE HELP!!!!!

THANK YOU

On the 06 RXP guide, the long beep could be:

Bad DESS system connection.
Wrong safety lanyard.
Defective safety lanyard.
Dried salt water in lanyard cap.
Defectve DESS post
Improper operation of ECM or defective wiring harnes.

a bad ECU COULD BE THE PROBLEM

[4-techscharger]

I Dont Believe It Was The Ecu Because The Stock Didnt Pass 7,700 Rpm's And I Changed To The Rr Ecu And It Went To 8,000. I Need To Be At 8,300, So The 7,000 To 8,000 Is 300rpm Jump, But Im Missing It On The Max Rpm's

I Have No Idea What It Could Be Now, Im Out Of Solutions

Have you ever had your prop re pitched ?

[buddydoo]

4-tech,what year is your RXP,is it a 04.

[4-techscharger]

I have a 2005

My prop hasnt been re-pitched yet, im waiting to see what the problem is, because the stock computer is supposed to rev up to 8,100 RPM"S so its not the pro.

I think its the key or sensor area, because when i put the key on it beep twice, then one long one and then the normal 4 beeps telling you the key is on.

Should I hook up the stock computer again and take it to a good dealer and check it out or what????????

Im going crazy over here..... so much money and havent been able to ride it

PLEASE PLEASE....LOL
