5.2 Conexiuni de cablare

1. Deconectați bateria: Always disconnect the negative terminal of your vehicle's battery before beginning any wiring.
2. Coil Pack Connection: The main wiring harness of the 8733 module connects directly to your factory coil packs. These are plug-and-play connections, designed to fit without modification.

3. Alimentare (fir roșu): Connect the red wire from the 2-Step module to a switched 12-volt power source. This source should only be active when the ignition is on.
4. Împământare (Fir negru): Connect the black wire from the 2-Step module to a reliable chassis ground point. Ensure the connection is clean and secure.
5. Activation (Blue Wire): The blue wire is the activation wire. This wire needs to receive a 12-volt signal to activate the 2-Step function. Common activation methods include:
   • Comutator ambreiaj: For manual transmissions, connect the blue wire to the output side of the clutch pedal switch that provides 12V when the clutch is depressed.
   • Transbrake/Line Lock Switch: For automatic transmissions, connect the blue wire to the activation wire of your transbrake or line lock system.
   • Momentary Push Button: Install a momentary push-button switch that provides 12V to the blue wire when pressed.

5.3 Setting Launch RPM

The MSD 8733 module features two rotary dials for setting the desired launch RPM. One dial adjusts in increments of 1,000 RPM, and the other in increments of 100 RPM. Combine the settings on both dials to achieve your target launch RPM (e.g., setting the 'x1000' dial to '2' and the 'x100' dial to '5' will result in a 2,500 RPM launch limit).

Start with a lower RPM setting and gradually increase it as you test and become familiar with the system's response and your vehicle's traction capabilities.

6. Instrucțiuni de utilizare

Once installed and configured, operating the MSD 8733 2-Step Launch Control is straightforward:

1. Ensure the vehicle is in the appropriate gear for launch (e.g., 1st gear for manual, Drive for automatic with transbrake).
2. Engage the activation switch (e.g., depress clutch, activate transbrake/line lock, press momentary button).
3. Depress the accelerator pedal fully. The engine RPM will rise to the pre-set launch RPM and hold there.
4. Release the activation switch to launch the vehicle. The 2-Step will disengage, allowing the engine to rev normally.

Note: Practice in a safe, controlled environment to determine the optimal launch RPM for your vehicle and conditions.

7. Întreținere

• Verificați periodic toate conexiunile cablurilor pentru etanșeitate și coroziune.
• Ensure the module remains securely mounted.
• Keep the module clean and free from dirt, moisture, and debris.
• Avoid exposing the module to extreme temperatures or harsh chemicals.

8. Depanare

8.1 2-Step Not Activating

• Check all wiring connections (power, ground, activation, coil packs) for proper installation and security.
• Verify that the activation wire (blue) is receiving a consistent 12-volt signal when the activation method is engaged.
• Ensure the module is receiving constant 12-volt power and a good ground.

8.2 Incorrect Launch RPM

• Double-check the settings on the rotary dials on the module.
• Ensure the module is compatible with your engine's trigger wheel (24x or 58x).

8.3 Engine Stumbles or Misfires During 2-Step

• This can sometimes occur if the launch RPM is set too low or too high for your engine's setup. Adjust the RPM in small increments.
• Ensure your ignition system (coils, spark plugs, wires) is in good working order.
