KV12 ECU Data Sheet Emtron’s KV12 is a wire in ECU with extreme flexibility. Industry leading I/O count will ensure you do not have to make any sacrifices when configuring your eng ine and vehicle. This ECU will support up to 12 Channels of Fuel (6 cylinders fully sequential staged injection) and 12 Channels fully sequential Ignition. Every KV12 is housed in a durable billet Aluminium enclosure and includes up to 64Mb permanent memory for on board logging and oscilloscope function, twin DBW control, twin Lambda controllers, twin digital Knock control, Ethernet communications and 3 axis G-force sensing to name a few. 1.0 General Power Supply Operating Voltage: 6.0 to 22.0 Volts DC (ECU shutdowns at 24.0V) Operating Current: 350mA at 14.0V (excluding sensor and load currents) Reverse Battery Protection via External Fuse “Smart” Battery Transient Protection Operating Temperature ECU Internal Temperature Operating Range: -30 to 110°C (-22 to 230°F) PhysicalExternal: Enclosure Size: 134 mm x 162 mm x 27 mm Weight KV Series: 0.74kg Internal: Dual 100MHz Processors 500MB DDR RAM (0.5GB) Up to 64MB permanent memory storage for ECU logging and Oscilloscope Function Up to x10 channel Oscilloscope function o Sampling at 500k samples/second o Includes Crank and Cam sensors inputs o Includes Digital Inputs 1-8 On-Board Barometric Pressure Sensor. o Range 40 - 115.0 kPa 3-Axis Accelerometer o 16 Bit Resolution o 2g/ 4g/ 8g dynamically selectable full-scale o Output Data Rate 500Hz Communications Ethernet 100Mbps. High Speed communications channels used for tuning and uploading ECU log files. 2x CAN nodes/ 6 Channels per node 2.0 Injection The ECU can control both modes of injection: Saturated and Peak & Hold. Peak and Hold - 12 x channels When using low impedance injectors (< 5 Ohms) the ECU uses a switch mode current limiting technique to minimise heat dissipation in the Injector. This gives better injector control and helps maximize injector life by lower its operating temperature. Independently configurable Peak and Hold currents up to 12 cylinders Max Peak current 8A Max Hold current 2A Current limited to 10A. Flyback Voltage Clamp: 60V. Saturated Required when injector resistance is greater than 5 Ohms. Current limited to 5A. Flyback Voltage Clamp: 60V.
