the ECU manager has rudimentary control over the SLM.
But it is still based on a 2d table with Y and X axis if you configure it. Can only have 4 sites on the Y axis and 8 for the X axis (one per LED). The X axis is what dictates when the LED combination and color get turned on.
Makes for an acceptable light patterns but if you have an SDL or ADL2/ADL3/ACL then that would be preffered.
for the time being...mine's just setup to light up at 4 different RPMs. Once my mag wheel sensors come in...i'm gonna set it up to display different LED colors/patterns at different gears/rpm shift point.
mazi seems to have found a way to work around the rudimentary controls the ECU has over the SLM.
