2.4l Opel 8V CIH Competition EngineTiming, Ignition and Engine Management
An Emerald Distributorless Ignition Engine Management Unit is used to control the engine operation. This system uses a throttle potentiometer, coolant temperature sensor and air temperature sensor, together with the timing sensor data to provide a map with 8 load sites and 24 speed sites, which are altered for air and coolant temperature. The speed sites are in 500RPM steps up to 12,500RPM, and the load sites are evenly spaced between idle and full throttle. This management system has both a soft and hard rev limiter. The timing system uses the crankshaft pulley and timing sensor from the 2.4i Fronterra. The distributor has been cut down, so removing the distributor head, and capped. What remains of the distributor unit is used to drive the oil pump The timing and ignition system can be seen in more detail on my Ignition/Injection Systems pages. Back to Top |
