Sync Sensor Used
This parameter works in conjunction with missing tooth mode and Subaru from 2001 mode if you want to fire injectors and igniters sequentially (one coil per plug and one injector per port). Because most missing tooth wheels run from the crank or run the same RPM as the crank the ECU will receive 2 index signals per cam cycle and therefore true sequential is not possible. By reading a TDC sync signal from a cam or distributor wheel the ECU can then run in true sequential mode.
