Read and understand these instructions BEFORE attempting to install this product.
 Engine Wiring Harnesses, ‘swapped’ engine installations
It would be very wise to double-check that the
vehicle’s wiring harness destinations
match the pinout chart provided in this document. This is especially true if the vehicle
contains a ‘swapped’ engine or if the wiring harness has been cut, spliced, soldered,
tapped or modified in any manner. It is the user’s responsibility to check that the
wiring on the vehicle matches the pinout chart in this document. AEM will not be held
responsible for loss or damage that can occur if the EMS is installed in a vehicle in
which the wiring harness does not match the AEM-supplied pinout chart!

EMS Fuel Map, Boost Fuel Trim Table
The 30-6030 calibration maps provided utilize the “Boost Fuel Trim Table” to provide
a 1:1 fuel compensation above and below atmospheric pressure. To use this table,
the “Boost Fuel Trim Table” should be configured to provide twice as much fuel when
the manifold pressure is twice as high and half the fuel when the manifold pressure is
half as high; this should help simplify the tuning process for different vacuum and
boost levels. Notice the values in the main
“Fuel Map” do not change above 100 kPa
(0 psi boost), the fuel correction is being made by the “Boost Fuel Trim Table.”
Note: the
“Boost Fuel Trim Table” must be adjusted if a different MAP sensor is
installed or if the Load breakpoints are adjusted. The Boost Fuel Trim value should be
set to -
90 at 10kPa, 0 at 100 kPa, +100 at 200 kPa, +200 at 300 kPa, etc…

Honda Multiplex Control
The supported vehicles utilize a Multiplex system which communicates with many of
the vehicle’s control modules. The 30-6030 Series 2 EMS is different than the 30-
1030 Series 1 EMS since it does not require the stock ECU to be installed for the
coolant temperature gauge and air conditioning switch to function.
If the AEM 30-6030 EMS is being installed into a different vehicle which does not use
the 01-05 Honda Multiplex system, there is no action required in either the software or
the hardware.
Note: When using the 30-6030 EMS, always use the 30-6030 specific Coolant Temp
Wizard calibration (note: this has been configured in all the 6030 startup calibrations).
Internal Logging
Since these vehicles do not have a constant 12V wire in the factory ECU harness, a
permanent 12V wire must be installed at Pin C1 for the Internal Log Memory. The pins
and connector in this kit can be used. Note: PC Logging can still be used to record
data from the EMS while the laptop is connected to the vehicle, it does not require
power at pin C1.
Check Engine Light
The Low Side 10 output (LS10) activates the Check Engine Light on the gauge
cluster. It is configured to activate at high RPM in the AEM startup calibrations; this
can be reconfigured by selecting Tools>>Configure Outputs.
