ECU Concern

[sampson.pomerleau]

Hey All,
I ran the 48 8350 35 34 101 tune for my 2013 SEADOO RXP X 260 and its not starting in Sport mode and I can barely break 70 on smooth water. My RPM's are not exceeding 8000. Any Idea as to why this is happening? Below is the list of upgrades I have done.


2013 Sea Doo RXP x260
VIN: YDV17759C313



1 x RIVA Sea-Doo 'GEN-3' Power Cooler Core
1 x Solas 15/19 Impeller
1 x RIVA 08 and Newer Rising Rate Fuel Pressure Regulator set to 58
1 x R & D RXP-X 260 Pro Series 4" Air Filter Kit
1 x R & D Aquavein Intake Grate for RXP-X 260
1 x RIVA Sea-Doo RXP-X/RXT-X 260 Intercooler Tubing Upgrade Kit

yea id say you are down about 250 or more rpm you sure there is no limiters left on that tune?

Here were the options that I had. Just doesn't make sense why its not running where it should be. I sent an email to mike to see if the map needs to be updated or anything. '

Try a Different Tune. None of the ones I used start in sport mode. Check for boost leak.. aka all clamps and hoses.

How do I pick another tune. I set a pic of what I have for options. Am I missing another option?

I see 2 you can choose 2 from there.. just different rpm levels pick one you haven't tried.. test it.. If still same thing .. you'll know you have another issue.

I agree, check the simple stuff first. Your ski should run 75+ all day with those mods.

Leaky leaky maybe

[Gus13letter]

With those mods you should be right at 8100 rpm and 74 - 75 mph. As long as the prop is really a 15/19. Often times they are off. What do you mean it wont start in sport mode? The skis dont start off in sport mode.
Are you sure you flashed the ski?
Does it feel snappier? You will notice a big difference if you flashed the ski.

I believe your riding conditions or prop is the factor. 8000 RPM and the speeds your getting are not normal. To get to 74-75 mph, you need to have the RPM's around 8300.
