Thread: Motec Testing

    Motec Testing

    I was doing some testing on a Motec M130 today and playing with data rates. In I2, the Motec data logging software, I can export at several different data rates. I then open the logs in MegaLogViewerHD.

    Here are the same throttle stab at the three different data rates. 50 hz, 100 hz and the max of 200 hz with level 2 logging that I had available to me. I found that you can see almost everything you need at 100 hz.

    50 hz http://www.nbs-stl.com/motec/Motec%2050%20hz.png

    100 hz http://www.nbs-stl.com/motec/Motec%20100%20hz.png

    200 hz http://www.nbs-stl.com/motec/Motec%20200%20hz.png

    The bumps in the Duty Cycle and in the Pulse Width is the acceleration enrichment setting in.

    Way cool stuff

    It is nice to be able to see this much Data when you are tuning or doing trouble shooting on a problem.

    Yep, it just depends what you are looking for.

    At 200 hz data rate and lower rpm, you are seeing every injection event.

    I figured out how to effectively filter out Transients in a huge Motec log.

    http://www.nbs-stl.com/motec/TransientFilter.png

    On the left is the non filtered data. On the right is the filtered data throwing out data where the motor is change conditions quickly.

    Here is the filter I am using

    In MLVHD Simply create a new filter called TransientMotec and define it as

    (abs([Field.RPM] - [Engine Speed-4]) > ([Field.RPM] * 0.10) ) or [Fuel Volume Transient]>0 or ([PW1Motec]+[PW2Motec]+[PW3Motec])>(3.03*[Fuel Cylinder 1 Output Pulse Width 1]) or ([PW1Motec-1]+[PW2Motec-1]+[PW3Motec-1])>(3.03*[Fuel Cylinder 1 Output Pulse Width 1-1]) or ([PW1Motec-2]+[PW2Motec-2]+[PW3Motec-2])>(3.03*[Fuel Cylinder 1 Output Pulse Width 1-2])

    Check out the Pulse Width and Duty Cycle as I tap the throttle.

    That rise in PW as I tap the throttle is the Motec sending a second Pulse Width to account for the acceleration of the motor.
