Might just want to try that to start. And using wasted-spark will take care of the 180-degree firing-order and avoid needing a cam-sensor. |
With a MicroSquirt ECU running MS2/Extra firmware it's just best to use a trigger pattern that is
supported by the firmware.
I don't know if the current MS2/Extra firmware includes support for the Nissan SR20VE ignition system, but I do know for sure that the firmware does support the use of a standard 24-2 trigger wheel. And, besides, that "wheel" (which on the EX250 is simply the alternator rotor) is a direct-swap-in to the EX250 from an EX300. It all doesn't get any simpler than that.
