Starting the Engine

1.Refill the engine oil to factory spec.

2.Check all the hoses and wires connection, then reconnect the negative side of the battery.

3.Turn the ignition to “ON” position 2-3 times to get fuel pressure. Then, check the injectors and the fuel rail for any fuel leaks.

*Repair any fuel leaks before starting the engine. Starting the engine with a fuel leak can cause fire in the engine compartment and can be very dangerous.

4.Remove the ECM fuse and crank the engine to get oil pressure to the turbo. (Until the oil light on the dash turns off) Check for any oil leaks, then reinstall the fuse and start the engine.

5.While idling, check for any oil, coolant, or air leeks.

6.After inspection, reinstall the under cover and other stock parts that was removed.

7.On the initial run, be sure to have a boost gauge to check the turbo-actuator setting. This turbo kit is preset to boost between 0.4kg/cm2 to 0.45kg/cm2 .

It is very important that you monitor the boost pressure, and make sure not to over boost. Over boosting can cause engine damage.

This completes the Turbo Kit installation.

ACTIVE L.E.D.

(2)When the ignition is turned on, it will illuminate and flash GREEN.

(3)When it reaches to the A.A.V. setting RPM range, it will illuminate and flash ORANGE.

(4)When an error is detected it will flash RED.

INTERACTION L.E.D.

3. This will illuminate when there is a connection with PC.

Checking Error Codes

When the unit is powered up and if there are any errors, the ACTIVE L.E.D will turn “RED” from “GREEN”, and begin to flash.

If this happens shut the engine off and turn the ignition switch to “ON” position to go to Self Troubleshooting Mode. While in the Self Troubleshooting Mode, the L.E.D. will show the error code. Turn off the ignition. Check the error code in the chart below and fix the problem. The error code will show until the error is corrected.
