What is an E-Manage? What can an E-Manage do? An E-Manage belongs to the category of electronics called piggyback controllers. They are called this because the do not completely replace the factory engine management unit, but rather work in conjunction with the factory unit to allow you to tune and control specific aspects of the engine's operation while allowing the the original to maintain control of the rest. It is the best of both worlds!

Today's engine management unit is an incredibly complex piece of machinery. It does far more than simply control the delivery of fuel and ignition to the engine. They also control valve timing and are responsible for adjusting emissions. Nearly every piece of electronic equipment in the car ties its operation into the ECU. You can't simply yank it out and expect the car to operate correctly.

Fortunately, there is hope for the auto enthusiast who needs to extract more performance from his or her car than the stock ECU was intended to provide. That hope is the GReddy EManage. This precision controller will allow you to adjust a broad range of performance-related controls in concert with the ECU. The result? Killer performance and a car the works properly, as the manufacturer intended. Consider just a few of the things you can control with your GReddy EManage:

Fuel Delivery - Compensate for upgraded mass air flow meters, throttle bodies, or fuel injectors.

• Adjustment of fuel delivery at 5 different RPM ranges
• Adjustment of air flow meter signal by up to 20%
• Incorporated Fuel- and Boost-Cut Controller
• Control of up to two additional injectors activated by boost or RPM level (with optional boost sensor)
• Idle adjustment circuit included

Ignition Timing Adjustment - Control your ignition timing under high-output conditions (with optional timing adjustment harness)

VTEC Timing - Have one of these in your car? Now you can do even more!

• Set valve timing based on Engine Speed
• Use your factory non-VTEC ECU with your VTEC engine swap!

The EManage even features password protection of the user's setup and stores its settings in non-volatile memory so settings are not lost if the battery is disconnected or dies. It's what you've been looking for!
