    Does the ECU monitor boost?

    I saw that WCShannon over on SDN wrote this"

    "What I did(and GP can correct me on this if it isn't so) was to take my ski up to my dealer and he did a computer analysis to see what the last psi thrust was when I last opened up the throttle. He tells me that if it falls within like, I think, around 24 it's ok but if it comes within 2 or 3 from what it's supposed to do then BRP will allow them to change it out. Evidently the clutch has begun to slip and loosing thrust. He even said he would put the Rotax clutch back in it if I wanted him to...so until then, I'm keeping an eye on the psi before it totally wears out...although there has been some that have disintegrated before they started wearing out!"


    So if oyu bring your ski in and hook it to BUDS, they can tell if boost is going down?

    I can`t say, bc I don`t know for sure, but with the map sensors, the ecu would get vac/boost signals to change fuel/spark requirements , I think...
    so then I could believe that the ecu has a way of monitoring the range or value of said sensor...

    depends on what mods you have. From my undersatnding of it you can reflash your ECU with a programmer and adjust the fuel flow which in turn will increase your boost potential. So in the long run I guess you can say it can control your boost.

    How are you reflashing the stock ECU?

    The ECU monitors manifold pressure. I don't know if BUDS records and stores the values or not.

    Ken, you cannot reflash your ECU with different fuel mapping.

    I don't think the mechanic knows what he is talking about. He says something about 23-24 PSI of boost.
