DONT BE LED TO BELIEVE THAT E-MANAGE IS ANY LESS PROGRAMMABLE THAN POWERFC!!!
There are a number of components to the E-manage system. Let's break
each one down.
E-manage main unit – the main brain of the whole deal. The unit by itself is VERY basic – there are 5 knobs you can adjust on the front of the unit to do a
VERY rough fuel map with. IMHO, the computer by itself isn't much, the
Support Tool is what makes it shine.
E-manage Support Tool – Now we're getting somewhere. Included in the
kit is a serial to USB cable and a CD with the Support Tool software.
The cable is proprietary, and not a standard cable. The software
unlocks the full potential of the E-manage – 16x16 fuel maps, changing
airflow meters, using the other optional harnesses, etc. You really
need to have the Support Tool for the E-manage to be of any value.
Optional Injection Harness – This splices into the stock fuel injectors
for control and logging. With this harness, you can directly add
pulsewidth to the stock injectors and datalog their activity. You can
also directly control 2 additional injectors as well. This retails for
NOTE: You can buy JUST the ignition harness and use the extra wires
for the injector harness. The ignition harness comes with 12 wires and
an extra connector to plug into the E-manage. Most cars don't use all
the wires – 4 cylinder and rotary cars especially. Look at the E-
manage manual, find your car, and find out how many wires you need for
igntion control and for injector control. Make sure to add 2 wires to
the total if you plan to use additional injectors. If the total is
less than 12, buy just the ignition harness and add the extra wires to
the main E-manage plug for your injector harness. The injector harness
is just some wires with ends crimped on them that you add to the main
E-manage plug.
Optional Ignition Harness – This splices into the car's timing input,
from a crank angle sensor, cam angle sensor, or the like. With this
you can alter the car's ignition timing.
Greddy Pressure Sensor – This is a 3-bar air pressure sensor add-on.
With it, you can tune your fuel maps with this sensor's output as the
basis for tuning instead of the car's airflow signal input. This is
primarily used when you've overrun the capacity of the stock airflow
meter. Whether or not you need this is a tough question – it's really
best to run the car without it first and see if you're maxing out the
stock airflow meter signal before purchasing.
NOTE – the peak/hold/warning Greddy boost gauge uses the SAME sensor,
so you can share that sensor's output with the E-manage.
Pressure Sensor Harness – it's simply the wiring harness to plug the
sensor into the E-manage. If you're using the boost gauge's sensor,
you can buy just this harness and tap it into the boost gauge's
harness.
The best setup to start with is the main E-manage computer and the
Support Tool. Next would be the injector harness, then the ignition
harness, then the pressure sensor. If you need control over ignition
timing as a priority, you might want to look into the ignition harness
first over the injection harness, or do the trick below to use parts of
the ignition harness as the injection harness. Regardless, the
pressure sensor is probably lowest on the priority chart - it's moreso
something you get when you know you're overrunning the stock airflow
measuring device. It might be more of a priority if you have a non-
turbo car with a turbo kit and the stock pressure sensor for the car
doesn't read boost pressure. Again, it really comes down to what
you've done to the car, what you're planning to do, and what you want
from the E-manage.
The E-manage really works well with larger injectors, and larger
injectors are highly recommended. Greddy advertises that you can
increase injector size 150% - this is not really a limitation of the E-
manage, but of the engine itself. Larger injectors will squirt more
fuel at their smallest pulsewidth, and too large injectors will cause
idling and running problems. But, additional injectors can be added as
well to supplement the stock injectors.
The closest competition to the E-manage is the Apexi Super-AFC. The
Super-AFC is a very nice and powerful unit, and they both have their
advantages and disadvantages. The E-manage is far more capable, but
does require a laptop (or the E-01 boost controller) to program. The
Super-AFC is simpler, but is self-contained – you program it right on
the unit's display. The Super-AFC doesn't handle larger injectors as
easily as the E-manage, doesn't control additional injectors, doesn't
do ignition timing, and doesn't have datalogging (though it does do
some MAP tracing on the screen, but they can't be saved and are tricky
to interpret). It's still a great computer, though. The E-manage is
really the next step up.
When the E-manage came out, there was a big confusion about the Support
Tool – supposedly you could only get it from an authorized Greddy
dealer when they install and tune the E-manage for you. This has
proven not to be the case. You still can't easily get the E-manage
from many on-line vendors, but it is available.
