where can i find the torque optimization (minimum best timing / optimum lambda / optimum cam timing) that is being used in the dyno experiments? i am using a motec m1 software
I have a several worksheets for M1 Tune 1.4 to help me do this. In my own firmware projects, I have a dyno object, that can receive the current Dyno Torque over the CAN bus, and update a channel called "Measured Torque".
For GP firmware, I send the torque data over the CAN bus and assign to a channel that won't affect anything (like transmission temperature). On my worksheets, I have a XY graph with torque on the vertical axis and the variable I'm changing (like Ignition Timing) on the horizontal axis. I also include a graph showing, the EngineSpeed, load axis, dyno torque, and knock).
I set the dyno to hold a fixed RPM, then highlight the cell I want to change, then apply the throttle to hit the target. Now I can change the timing using Pg Up / Pg Dn keys, and see the torque vary. It's easy to pick a point just before it flatttens out (and with no knock showing), and type that into the cell. I then move to the next higher load cell and repeat. Sometimes i need to rescale the XY graph torque range as I increase the load. I want to be sure to see the differences as the cell value is changed.
In the demo's that Andre presents, they are using a Mainline Dyno, which has the feature that it can read the ECU data for Timing, Lambda, and it performs the graphing, and optimization finding. But as long as your dyno can transmit torque, it should be possible to do this all in the M1 ECU.
