Please advise what you believe would be the best system to run in this from your company as well as pricing and availability ---- 1 [http://shop.vems.hu/catalog/vems-p-48.html VEMS ECU] can drive it if it has 12 high-Z injectors * 2 high-Z injectors in parallel is fine * ignition options: ** use the oem twin distributors ** optionally use wasted spark coil (either active coils driven by logiclevel ignition outputs or passive coils driven by IGBTs) ** or last option use 12 active COPS * choose 2 knocks * also '''request "2 WBO2 and lotsof extra inputs and outputs on extra EC10 connector" in the order comment''' (to have some extras above the bare mnimal) ---- '''Primary Trigger''' (crankshaft, most likely 60-2) VR or HALL ? * if you find 2 pins that measures same resistance in both directions (usually between 300 and 1500 Ohm) that is VR. Otherwise HALL '''Secondary Trigger''' (camshaft) VR or HALL ? * if you find 2 pins that measures same resistance in both directions (usually between 300 and 1500 Ohm) that is VR.
