    Brucato when looking at live data on the program

    I have an old PCU that runs an engine very very rich. I hook it up to the program and look at live data and the manifold pressure is 1198 units. Not sure what that reads are exactly, but I think 80 units is equal to one inch of mercury. The fuel curve graph only goes up to 980 so I think the map sensor is reading very very rich and that is why it will not properly run an engine with it.

    Anyone know what their box reads with the motor off for manifold pressure?

    thanks

    ok, so your just about 1002 units of manifold pressure before you start the engine. Mine is at 1198 on this pcu that someone replaced the MAP sensor on. I wonder if the map sensor is not the correct one or something as the motor is so very rich it is hard to keep it running on the trailer.

    If they did not go through the trubble of getting the correct sensor that would most likely be the cause!
    Might want to send it to brucato
    They can also update the software to make use of the excel program

    Brucato will not touch it and I am able to program it, it takes the curves just fine, just doesn't read manifold pressure correct it seems. Anyone know where to get a map sensor for one of these?

    Digikey, mouser, farnell!
    you probably have a 100kpa sensor now but is a bit of a crap shoot this way

    I am wondering how the sensors are made for what bars of pressure? I see alot of 3 and 4 bar sensors but I think a brucato goes up to 12-13 bars of pressure.

    that link does not work, was it a specific part or just a link to the pressure sensors?

    You broke digikey
    Sensor is mxp2200

    what is the difference between MPX2200AP and MPX2200GP? One is Absolute pressure and the other is Gauge pressure. What one does the a Brucato want?

    i think you need the DP!
    dual port differential but agian not sure

    Hmmm. MAP is Manifold Absolute Pressure. I do have someone at Brucato trying to find out but I am not sure they will tell me!

    I think you are correct. I just looked at an ACU and it is a dual sensor. I need to find a picture of a unmolested PCU to see if it is the same with 2 ports

    So I looked at my buddies PCU that is about the same year, they do not have the Differential sensor (MPX2200DP). Looks like a MPX2200AP or MPX2200GP. I hope the lady at Brucato was able to get some info when I call her today. Would be nice to get this PCU working so I do not need to buy a new ACU!
