AEM Chevy/GM 58x LS PNP Engine Harness for Crate Motors and Racing Engines

AEM Chevy/GM 58x LS PNP Engine Harness for Crate Motors and Racing Engines


The Infinity 58x LS Plug & Play engine harness (PN 30-3801) is designed to work with the Infinity 508 ECU (PN 30-7108). It connects to the factory sensors and factory ignition coil sub harnesses for fast installation. Install and start tuning in hours instead of days!

An integrated, weather resistant fuse and relay panel delivers superior circuit protection, and an additional High Performance DTM-Style connector is included to allow users to wire the fuel pump to the Infinity for full control. Individual coil sub harnesses are not included.

The Infinity EMS delivers high-end engine control for the racing masses at a fraction of the cost. The Infinity 508 for LS race engines uses airflow-based tuning models to simplify start up and speed up the tuning process by eliminating many of the lookup and trim tables (Correction Tables) necessary in previous generation ECUs.

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.

  • The Infinity’s 200MHz processor and RTOS makes the Infinity more responsive, for a better driving experience

  • The Infinity’s 200MHz processor and RTOS allows for more accurate ignition timing, which enables an engine to create more power

  • The Infinity’s faster processor allows it to perform more computational features with no sacrifice in processing performance

  • The Infinity’s RTOS ensures strategic processing with optimized load balancing. This means that tuning one feature will not affect the performance of another feature
