    Pegasus Max RPM

    Hi Benny !

    Here's a blast from the past !!!

    I have an old air start Pegasus Mk3, SNo 8101003, Date of delivery 14/10/1998
    ECU:HWVER 970801 SWVER 4.31

    When I use ECOM (PC serial comms software) to interrogate the ECU parameters, I get:
    NVN 006
    IDR 033.0
    MXR 110.5
    OVR 118.5
    WTM 174
    STO 045
    TLT 033
    VMI 090
    QMX 026
    PCA 070
    UTM 001
    NSR 000

    The maximum RPM for this engine was quoted as 112.5k rpm
    We never set it this high, it was left at 110.5k rpm
    Is it OK for me to change MXR from 110.5 to 112.5 (nnn = 225)
    Leave OVR at 118.5 ?

    I cannot seem to toggle UTM, unhook thermcouple, by pressing "U" in ECOM.
    UTM = 001 means that the ECU looks for overtemp at startup only, not during flight.

    What is NSR parameter ? I cannot find any reference in the manuals and .txt files.



    Thank you.

    Jules.
