    TWIN EVINRUDE 250HP 2004 FICHT

    I have two of these units, that were out of service and someone helped themselves to the EMM. I was able to purchase a second hand unit, and also had to replace the wiring harness. My question is, how do I update the fuel injector coefficients now. Ive been through the diagnostic software and i can see the disparity in the performance parameters for individual injectors, so I now see why these engines can easily suffer catastrophic failures by just swapping injectors to different cylinders. Is there somewhere I can email my injector serial numbers to to get the data files to load into the EMM? I am really frustrated, just listening to my engines idle for weeks now
