APB (2000 to 2005) 2.7T

Disclaimer – The 2-step launch control system should
only be used with a complete understanding of how it functions and the
potential hazards of use.

The 2-step launch control works by cutting ignition momentarily and allowing
the injectors to continue injecting fuel. The unburned fuel will ignite in the
manifold and exhaust system allowing the turbo to build pressure while the
vehicle is stationary. The extreme temperatures from this can overheat and
damage components of your exhaust system (turbo, catalytic converter etc…) if
used for too long. For this reason we recommend that the 2- Step only be used
in off-road vehicle applications.

Activating the 2 Step and no Lift Shift features requires that you first
activate this feature using Maestro 7 and the following procedure.

Step 1.Plug in your Powertap interface and launch the Maestro 7 software
program – update if you are instructed to do so

Step 2.Using the file menu open your current tune file

Step 3.Select the 2 step and no lift shift feature (towards the bottom
of the menu choices) this will open a feature selection screen

Step 4.Select 2 step and no lift active and save the file to a new name
2Step

Once 2 step has been set to active you must flash the new file to the car and then enter the desired operating parameters.

Step 1.Open Eurodyne Flash client and select flash ECU and select the file saved in the operation above
Step 2. Once the file has been successfully written to your ECU select the “Read Settings” option found in the Diagnostics drop down menu
Step 3. Select the 2 step and switching option tab
Step 4. Set the “Speed” option – this will establish the road speed in KPH for 2 step deactivation – a setting of 2 will cause the 2 step to be active below 2 KPH and limit RPM to the level set in the RPM limit box (see next step). A setting of 0 turns 2 step off
Step 5. Set “RPM limit” this establishes is maximum engine speed with 2 step active (vehicle speed below threshold set above)
Step 6. Enter desired “No lift shift” value (allows driver to upshift with the accelerator pedal fully depressed by deactivating the ignition circuit to limit RPM for the time delay entered in milliseconds – once time delay has expired normal engine operation will resume)
Step 7. Slect the write seting button to save the values you have entered
