for the d599a coil, yes, wastespark=on, everything else off.
if not using the 2-step, you don't need to set the trig limit.
To activate the 2-step you need a switch of some sort, you can trigger on applying a voltage, or switching to ground. (just some config switch changes)
The gray wire is an analog input that can be used to control the 2-step RPM setting remotely,
the rev limit in the TR6 is independent of the chip, since you don't have alky injection its less important, but set the LIM setting higher if you want the chip to control
the rev's, or set it lower than the chip setting if you want the TR6 to control the rev (overrev)
