Input Trigger

Standard Distributor

Input trigger: negative terminal of normal points distributor.

Electronic Distributor

Input trigger: negative terminal of electronic distributor

Nissan Optical CAS

With Nissan 360° CAS, use MegaSquirt 3 with 1.3.3 software. This includes SR20, CA18DE/DET CAS or the D4P distributor but modified to fit in A-series engine. See MS3 pre-1.3.3 beta 5 released (urgent for Nissan CAS).

MegaSquirt 2 will work if you swap the trigger wheel for a 22-1 wheel from DIYautoTune.

CA18DE Ignitor

Use MegaSquirt 2.0 to control the CA ignitor. MegsSquirt 3 can directly drive COP, but by using the ignitor it will work with MegaSquirt 2.
