Installation overview
Important: Please install the KManager software before plugging in the ECU
Engine Ground
It is very important that the ground from the wiring harness to the engine (G101) makes good electrical contact with the cylinder head. Otherwise the return path for the sensors, ignition and VTEC may be through the ECU case to the vehicle body, which may damage the ECU and/or programmable board inside the ECU.
The recommended position for the engine ground is on the stud attached to the cylinder head. While the stock location on the intake manifold will usually work without problems, the stud on the cylinder head provides a better electrical connection.

It is easiest to plug the USB cable into the ECU before you install the ECU as the USB connector is hidden once the ECU is install into some vehicles. Take care not to place any strain on the USB connector and the circuit board inside the ECU.
Take care not to short the metal shield around the USB connector to the ECU case or chassis ground.
It is not necessary to ground the case of the ECU.
Immobilizer
If the immobilizer light on the dash blinks (green key symbol) then you may to re-enable the immobilizer.
If the ECU does not match and vehicle (key and immobilizer transponder) then it is possible to disable the flashing immobilizer symbol simply by unplugging the immobilizer transponder (located on the ignition switch barrel).
