This ECU has been designed specifically for 2 rotor rotary engines. The new firmware is designed specifically to run rotary engines. All of the Stinger features have been retained and other features specific to rotary engines have been added. One ECU fits all. The same Stinger S-2R ECU can run both RX7 and RX8 rotary engines. Key Features 4 User Definable outputs. The outputs can be programmed as digital or PWM. These can be used for controlling thermo fans, Idle controls, variable cams, fuel pumps, Boost Control, Variable water spray, etc. 4 Sequential Injector outputs able to accommodate 2 primary injectors plus 2 staged injectors. Individual rotor trim for fuel and ignition. Full 3D maps for fuel, leading ignition and trailing ignition. 4 Sequential Ignition outputs (Coil-on-Plug) 7 Dedicated Analog inputs Water Temp, Air Temp, Lambda 1, Lambda 2, Throttle position, Manifold pressure and Battery volts. 1 User Definable Digital input for Nitrous control, Two step rev limiter, air conditioner idle-up, launch control, etc. Adjustable RPM and load points for Fuel and Ignition maps. The system offers 40 RPM points with a 1 RPM resolution and 21 load points with a 0.1 percent resolution. This provides a tuning grid of 840 points. Of course you don't have to use this many. You can define any number of RPM and Load positions you require to tune with. This provides non compromised tuning ability. The advanced micro code will perform a 3 dimensional interpolation between all load points. Connects to most sensors. This means that you can use your existing sensors with the Motorsport Series. Advanced trigger circuitry. Automatically filters trigger inputs for noise ensuring that the trigger signal is always 100% accurate. This combined with the advanced auto signal tracking and true zero crossing detection with magnetic sensors always provides accurate timing at all engine speeds. Advanced Micro Code EMS have put great effort in programming their micro code to ensure it stays in exact synchronization with the engine. This minimizes the risk of misfired and lean strokes therefore increasing engine life and providing more power. The system also performs a 3 dimensional interpolation between load points to ensure that your engine is getting what you tuned it to receive.
