The Infinity ECU for manual transmission equipped 1989-1998 Nissan Skyline GT-R RB26DETT racing engines (Infinity 506 PN 30-7106 and Infinity 508 PN 30-7108) includes an engine-specific start-up calibration and connects to the engine via a Plug & Play harness that is sold separately (PN 30-3515). Begin by determining which Infinity ECU will best support the ancillary components in your manual transmission-equipped Nissan RB26DETT engine using the Infinity Specifications Chart in the "Specs" tab. Complete Stand Alone Engine Control The Infinity ECU combines with the Plug & Play harness to replace the factory ECU. It controls all of the engine functions and the Plug & Play wiring harness adapter eliminates the need for cutting and splicing wires. Supports OEM Cam Angle Sensor The AEM Infinity ECU supports the Nissan RB26DETT's OEM Cam Angle Sensor (CAS) '360 Degree' pattern. The base calibration is pre-configured for the OEM CAS. The Infinity ECU can be reconfigured via the Setup Wizard to properly read the 12 crank/1 cam timing pattern on engines using an AEM CAS trigger disk. Supports Factory VTC The Infinity ECU supports the factory Nissan Valve Timing Control (N-VCT) system. Signal Conditioner for ATTESA AWD System on R34 Skylines The Infinity has a signal conditioner that ensures proper operation of the AWD system on R34 Skylines. Plug & Play Harness with Expansion Port AEM's sealed, weatherproof Plug & Play harness (sold separately) includes a Lambda connector, an AEMnet connector for communication with other AEMnet enabled devices and an auxiliary connector with a High Performance DTM-Style 12P connector for adding common aftermarket sensors. Visit the "Features" tab for more information about the Honda K-Series Plug & Play harness expansion port. Infinity Nissan RB26DETT Plug & Play Harness with Expansion Port Once you have determined which Infinity ECU will best support your Nissan RB26DETT M/T engine, you will need to purchase the RB26DETT Plug & Play adapter harness (PN 30-3515). AEM's Plug & Play harness for Nissan RB26DETT engines includes a Wideband O2 connector, AEMnet connector for communication with other AEMnet enabled devices and an auxiliary connector with a High Performance DTM-Style 12P connector for adding common aftermarket sensors including fuel pressure, air inlet temperature, MAP, oil temperature and ethanol content sensor. The expansion port also includes a sensor ground, 5v reference, 12v power from relay and high side output for activating a relay or solenoid, a low side output for boost control and analog inputs for mode switch and no-lift shift. The Infinity EMS delivers high-end engine control for the racing masses at a fraction of the cost. The Infinity Series 5 for Nissan SR20DET race engines is even more affordable than its larger Series 7 version because it is designed for smaller racing engines using low impedance injectors up to 6 cylinders or race engines driving up to 8 high impedance injectors. It features a smaller footprint than the Infinity Series 7 (5.855" x 5.55" x 1.8") and a single, weatherproof 80-pin connector. 200MHz Processor and Real Time Operating System Late model vehicle ECU's all run on faster processors. The Infinity ECU is built around a latest-generation 32 bit floating point 200MHz automotive processor and Real Time Operating System (RTOS), which is capable of processing 400 MIPS (millions of instructions per second). By comparison, common competitive systems typically use 20MHz to 50MHz processors. To our knowledge, the Infinity ECU currently has the fastest processing speed of any aftermarket Motorsports ECU available. This allows the Infinity to do more, faster, in a more stable programming environment.
