    I have a precision ECU and it works well for me. I support all the efforts to open up the ECU in order to keep these skis on the water.

    Hiperco , What about your problem with the phantom errors ?

    Have you managed to clear the phantom codes on your ecu eeprom ?

    I have three ecu for my jetski : two 110 and one 150 . On two of them i cant get the engine to run nice in iddle (1500 rpm) despite that there is no errors on the ecu . Do you have the same problem ? You have a crazy behavior of the idlle ? High rpm 4000-5000 rpm ???

    Hi krammer, I fixed my machine (finally) by replacing the O2 sensor. I suggest you could start a new thread asking about the problems you are seeing, since this one is to talk about ecu reflash

    (Do you have any progress in the ecu reflash area )

    Finnaly , i managed to read the entire flash file (512kb) from msx 110 and msx 150 without to desolder the 29f400. Still we need to open the cover for ecu to attach one wire for booting up the ecu . The tools i used for reading the ecu is one Ktag interface and Trasdata software . Both of them cost me 400 usd but i can use them to read and write almost all types of ecu's from cars , boats , truck, bikes .

    Now the next step is tunning the maps for our jet ski .

    Nice! I will follow up with you for details. Now as you say, on to the maps!

    Let's try to built a 20psi map! I will donate an ecu!

    What will be needed in the way of data logging?

    It sounds like he can read them.

    Reading the flash and editing the maps are two separate things. But let's let krammer fill us in.

    I assume when it's time he will need the afr and timing data logs at the least? I don't know if there are any loggers that would work with this system. I know the innovate afr system will work but for timing I do t have a clue.

    would want to watch intake temps as well.
