Nowadays "e" is affixed to everything from e-mail to e-commerce, and that added letter brings with it added improvement. The latest e-improvement is the GReddy e-Manage Ultimate.
The e-Manage was slated as GReddy's first PC-tunable piggyback engine management system. This unit filled the gap between the stock ECU and a full standalone engine management system. Although the original e-Manage had much to offer, the engineers went back to the drawing board and took their e-Manage to the next level: the e-Manage Ultimate.
At first glance, the Ultimate looks like the black chrome counterpart to the original blue e-Manage. Physical dimensions are the same, but you'll notice some significant differences. While retaining all of the best features of the original e-Manage, this unit sports more flexible fuel and ignition maps, the ability to switch between two different tuning maps (i.e. street tune and race tune), an increased number of input and output ports and a more comprehensive multichannel data-logging system. Gone are the rotary dials that occupied one side of the ECU. The updated chassis has a USB-B port, which can be used to link any USB 1.1-compliant cable to one's computer, two optional sensor ports, dip switches that activate specific fuel and ignition maps and accessory ports. Since the tuning software is bundled, you'll only need to purchase the harness kit.
As with the original e-Manage, the Ultimate uses both the 12- and 18-pin harnesses, and adds a 14-pin harness. The additional harness taps into several tuning and data-logging sensors, including knock, water temperature, crank angle, intake air temperature and vehicle speed sensors. If you want to upgrade from the original to the Ultimate, you can reuse your existing harnesses and buy the additional 14-pin harness separately.
The installation isn't for the novice tuner, because it requires electrical wiring experience to avoid potentially damaging your new e-Manage Ultimate or your vehicle's ECU and sensors. While the unit is universal, you must configure its circuit board to match your vehicle's specific sensor combination. Like the harnesses, if this isn't done correctly, the vehicle's electrical system and possibly the e-Manage will be damaged. Luckily, you can access the circuit board by simply removing one of the end plates and the two screws on the bottom of the chassis. This gives you full access to all 20 jumper options and allows you to configure them to work with your vehicle.
If you're upgrading injectors, the Support Tool software can make appropriate adjustments to accommodate the upgrade.
