Microsquirt Hardware Guide Models with a hall effect cam sensor should connect to VR2- and will require a pull-up resistor in the harness. Typical settings: Spark mode = IAW Weber Trigger angle/offset = 0 (adjust with strobe) Ignition input capture = Falling edge Spark output = Going High Number of coils = Depends on application Some applications use a single high current coil, others use coil-on-plug. External ignitors are likely required. 6.17 Mitsubishi CAS 4/1 Known applications include: • Mitsubishi 4G91 • Mazda Protege and 323 with optical distributor This consists of a Mitsubishi optical CAS. Electrically, the two signals on this CAS are connected the same as a Typical settings: Spark mode = CAS 4/1 Trigger angle/offset = 0 (adjust with strobe) Ignition input capture = Falling edge Spark output = Going High Number of coils = Depends on application You will need to set the “Angle between main and return” parameter to the distance between edges of the Note that if you are not able to get a stable signal off both edges, you should instead use "Toothed Wheel", mode with "Dual wheel" and 4 teeth at cam speed set. 6.18 Mitsubishi 4G63 (and Miata) Known applications include: • Mitsubishi 4G63 with distributorless ignition, as used in Eclipse, Galant VR4, and Lancer Evolution • 1990-1997 Mazda MX5 Miata (c) 2014-5 James Murray 2016-01-19 Page 126/155 | |||
