Cylinder Deactivation - Not Used With Chevrolet Performance Engine Control Kit
This engine is used in the Generation 6 Camaro. In production, to provide maximum fuel economy under light load driving conditions, the engine control
module (ECM) will command the cylinder deactivation system on to deactivate engine cylinders 1, 7, 6, and 4, switching to a V4 mode. The engine will
operate on 8 cylinders, or V8 mode, during engine starting, engine idling, and medium to heavy throttle applications. This system requires many inputs
(weight of vehicle, tire size, final drive ratio, etc.) to work properly. These parameters are unknown when selling the Chevrolet Performance engine
controller kit. Due to these unknown parameters as well as the need to tune the motor mounts and exhaust system for operation in both V8 and V4
modes. The Chevrolet Performance engine control kit disables this feature. The engine has not been changed, so cylinder deactivation hardware is still
present.

Ignition System

The Gen-V has an advanced 58X crankshaft position encoder to ensure that ignition timing is accurate throughout its operating range. The 58X
crankshaft ring and sensor provide more immediate, accurate information on the crankshaft's position during rotation. This allows the ECM to adjust
ignition timing with greater precision, which optimizes performance and economy. Engine starting is also more consistent in all operating conditions. In
conjunction with 58X crankshaft timing, the Gen-V applies the latest digital cam-timing technology. The cam sensor is located in the front engine cover,
and it reads a 4X sensor target on the camshaft phaser rotor which is attached to the front end of the camshaft. The target ring has four equally spaced
segments that communicate the camshaft's position more quickly and accurately than previous systems with a single segment. The dual 58X/4X
measurement ensures extremely accurate timing for the life of the engine. Moreover, it provides an effective backup system in the event one sensor
fails. Air Induction Humidity Sensor: This new feature ensures optimal combustion efficiency, regardless of the surrounding air's humidity. Coil-on-Plug
Ignition: The Gen-V's individual coil-near-plug ignition features advanced coils that are compact and mounted on the rocker covers, although they are
positioned differently than on Gen-IV engine. An individual coil for each spark plug delivers maximum voltage and consistent spark density, with no
variation between cylinders. Iridium-Tip Spark Plugs: The spark plugs have an iridium electrode tip and an iridium core in the conductor, offering higher
internal resistance while maintaining optimal spark density over its useful life. The electrode design improves combustion efficiency.
Fuel System
Low Pressure (Fuel Tank to Engine)
The production system uses a returnless variable flow/pressure system that has been incorporated in the Chevrolet Performance engine control kit. A
returnless fuel system reduces the internal temperature of the fuel tank by controlling the speed of the fuel pump and not returning hot fuel from the
engine to the fuel tank. The engine control kit includes a Fuel Pump Power Module, to regulate fuel pressure. The Fuel Pump Power Module must be
used to control the supply fuel pump. If it is not used, diagnostic codes will be set in the ECM but the MIL (mal-function indicator light) will not be set.
These codes can be seen with a scan tool and may cause a rejection at the inspection station.
