The Infinity ECU for manual transmission equipped 1989-1998 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). 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. 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. The Infinity ECU supports the factory Nissan Valve Timing Control (N-VCT) system. The Infinity has a signal conditioner that ensures proper operation of the AWD system on R34 Skylines. 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.
