AEM Infinity PNP Harness, Series 7 - GM LS Engine with 24x Timing Pattern

Vendor: AEM



If you have a Chevy LS crate motor or modified LS racing engine, AEM's LS Plug & Play engine wiring harness is the perfect solution for easily and affordably installing the Infinity Programmable ECU onto it. This harness plugs into the factory sub harnesses and uses the factory sensors. IP67-rated ECU connectors are designed to mate with AEM’s Infinity Series 7 ECU and connections for dual wideband O2 sensors, vehicle speed (VSS), Knock, AEMnet and CAN bus are integrated into the harness. The 58x harness includes a connection for drive-by-wire (DBW).

A Complete Standalone EFI System for Chevy LS Engines
The Infinity ECU combines with a GM LS Plug & Play engine harness to retain full control of the engine’s functions. It is ideal for crate motor solutions that are using aftermarket dashboards as they can be configured using the on-board CAN bus wiring (will not communicate with the factory dashboard on GM LS equipped vehicles).

The Infinity ECU is able to control the variable valve camshaft and drive-by-wire on equipped LS engines, providing tuners with the ability to take full advantage of the engine’s low-end power potential, and eliminate the need to convert to cable throttle. Users can create two drive-by-wire profiles for rain maps, pit lane limits and more.

AEM’s LS PNP Engine Harness also eliminates the restrictive factory mass airflow sensor (MAF) and airbox, making it an ideal harness solution for forced induction applications. Other key racing features include multiple boost control strategies, programmable nitrous control, on-the-fly map switching, programmable four-wheel speed traction control, launch control, flex fuel and multi fuel capability. It utilizes airflow (VE) based tuning, has up to 64GB data logging capacity and can transfer data at up to 480Mb/second. Its enclosure is sealed and suitable for engine bay mounting.



Chevy/GM LS Plug & Play Engine Harness for Crate Motors and Racing Engines
Once you have determined which Infinity EFI ECU will best support your Chevy/GM LS M/T engine, you will need to purchase a Plug & Play engine harness (PNs 30-3532 and 30-3530). AEM’s Plug & Play engine harness for LS engines includes Wideband O2 connectors for Bosch 4.2 LSU UEGO sensors (PN 30-3600 x 2 Wideband Extension Cables recommended), 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 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.

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 Series 7 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
