Purchasing an E-manage and E-manage options If nothing else, the E-manage makes for a great stepping stone before going to a full stand-alone – you can learn to tune the car while having the factory fuel map to fall back on. It's hard to say at what point it's wiser to go with a stand-alone than a piggyback computer (ie the E-manage) – it really depends on how good the car's ECU is to begin with, the amount of modifications, etc. This gives the ultimate in flexibilty, but with a steep learning curve and a LOT of work required to tune in the fuel map properly. A stand-alone ECU replaces the entire fuel injection system with one that's designed to be easily programmable by a laptop computer. While the E-manage is very powerful and flexible, a full stand-alone ECU is even more powerful. By increasing or decreasing this signal, the ECU will alter the amount of fuel going into the engine. In its most basic form, the E-manage alters the primary airflow input to the car's ECU. There are many additional options for the E-manage, allowing the user to put together a system that suits their needs. The intended purpose is to allow the user to fine-tune the fuel curve of the vehicle to take advantage of various modifications to the car. The Greddy E-manage is a simple fuel computer designed for Japanese automobiles.
