    Hours question *8)

    just wondering, i just bought a full wiring harness, ecu and mpem used from a green hulker... are the hours registered on the ecu? I just don't want to be in a situation where i'm all of a sudden adding xx hours worse yet xxx hours because the hours are stored on the ecu...

    btw today was a great day here in wisconsin... i rode a 85 kawasaki stand up on okauchee lake... interesting and definitely a lot more challenging to ride.

    The hours are stored on the ecu, but only read using BUDS software, the display shows hours. For example, if I put a 200hr ecu in a boat w/ 50hrs, the display shows 50hrs, but if hooked to buds by dealer for a readout (like warr. claim), it would show 200hrs. Got it?

    John, I think this may be correct with '06+ models, but is somewhat different with '05 and earlier skis. I know that when I swap out ECU's on '03 thru '05 skis the display will read the hours logged on each particular ECU. Hence, a 50 hour ECU will read 50 hrs... no matter which ski it is installed in. I have little experience with '06+ models but have been told that the newer ones store the data differently. Steve (shibby) could probably verify the parameters of each year model.

    I upgraded from a 185 ECU (approx 100 hours) to a 215 ECU (approx 64 hours). After BUDS hook-up (for key/lanyard) my ski started reading 64 hours. This is with a 2005 GTXSC and installed a 2005 RXT ECU. Just a FYI

    Interesting, I have 4 07' ecus, swap them between boats all the time (4 skis and a boat) and my displays always show hours on boat, not ecu. I even had to explain once why my rxp said 98hrs on the display but when the dealer hooked to buds it read 28.8hrs. the late boats don't even show tenths on the display...........who knows what the 06 is like. Shibby, where art thou?

    SHIBBY!!??

    im pretty sure the answer has been covered but i still would like some more insight...

    mainly i am looking to have the machine read what it had on it previously... 60 some hours. the ecu i just bought has 100 hours on it. can the dealer reprogram the hours in the ecu so my 04 will have the same amount of hours after i swap the ecu??
