    RXP Speedo Questions

    Ok - I know they're not accurate - but are relative but the speedo analog and digital stops at 70 MPH. - 7900 rpm or 7300 rpm - yields 70 MPH.

    Since the analog reads to 80 (but does go beyond 70)- why can't the ecu be reprogramed to read more accurate and past 70 - Some one must be able to do this.

    Happy riding ps - Had a great ride on the Mississippi this weekend - about 55 miles gps each way up the river - had to bring gas along to make the trip. No boat traffic at all - just lots of wildlife

    My speedo is stuck at 70 too. I have heard of very few reading past 70.

    I added an RX style Info gauge to my RXX and added an RX speedo - The digital stops at 70 - but the analog goes well past the 70 mph. GPS speed about 67-68.

    My digital goes past 70 all the time.As far as accuracy goes,they will never be completely accurate.Radar and gps is the only way to get true measurement.

    My speedometer hits 70 when my GPS is at 63 on my RXT but my GTX is only two tenths off.

    I leave the digital display on RPM mode all the time, and I never look at the analog speedo. I quit trying to interpret speedos long ago.

    But... back to the main question... someone must be able to reprogram the speedo ecu.

    It's not the ECU that makes the speedo unreliable. It's the spinning paddle wheel on the back of your boat which "measures" speed that makes it unreliable.

    Not to beat a dead dog but... On my snowmobiles ... the speedo is about as accurate as a seadoo deamo - but I use the speedo all the time when hill climbing - Every sled or snow condition has a fall out point - that the sled will trench out. That speed could be 30 - 35 or whatever. It's a relative number but still interesting to watch change as you make changes to the sled - The PWC speedo is a relative instrument - If your speedo reads higher after making a change - it probably means the boat is going faster - not as accurate as radar or gps - but relative none the less.

    So where is the limit programed to stop the speedo at 70 in the Seadoo?

    Thanks everyone for this and the other forums. Information is contagous.

    The limit is built into the gauge instrument
