2. Select TITAN II from the list. If this is the first time you connect, you must enter the PIN code that came with the product.

6. Set the right engine type – Single or Dual Solenoid Valve depending on the engine you have

7. Select the valve operating times appropriate for the configuration of your replica as described below

# Single Solenoid Valve Engine Calibration

1. Set the **Main Valve Time **to **15 ms**. 

2. Then proceed to chrono the replica. Depending on the weight of the BBs, the length of the barrel and the hop-up bucking, use the pressure regulator to preset the desired BB exit velocity.

3. Then decrease the **Main Valve Time** until the FPS do not start to drop. If you notice a decrease in FPS, return to the previous time value at which there was no decrease in FPS. This means that the Main Valve Time has been calibrated correctly. 

4. Next, go to the **Main Valve Pause** setting. This value depends on the quality of the magazine you are using. The weaker the spring in the magazine, the longer the pause will have to be. Proceed here similarly to the **Main Valve Time** calibration. Set the highest possible value and then decrease it until you notice pauses in the feed of the BBs through the magazine. If you continue to observe problems with BB feed, you should increase this time.

# Dual Solenoid Valve Engine Calibration

1. Set the **Main Valve Time **to **15 ms**. 

2. Then proceed to chrono the replica. Depending on the weight of the BBs, the length of the barrel and the hop-up bucking, use the pressure regulator to preset the desired BB exit velocity.

3. Then decrease the **Main Valve Time** until the FPS does not start to drop. If you notice a decrease in FPS, return to the previous time value on which there was no decrease in FPS. This means that the Main Valve Time has been calibrated correctly. 

4. Next, go to the **Main Valve Pause** setting. This value depends on the length of time the BB remains in the barrel. Set this value between **15 **and **1 ms**, and check which value will give a stable discharge velocity result for your replica. 

5. Next, go to the **Nozzle Valve Time** setting, this value depends on the quality of the magazines you use. The weaker the spring in the magazine, the longer the interval will have to be. Proceed here similarly to the **Main Valve Time** calibration. Set the highest possible value and then decrease it until you notice gaps in the magazine feeding the BBs, then return to the previous time setting. If you continue to observe problems with BB feed you should increase this time.

6. The last value is the **Nozzle Valve Pause** calibration. This function is responsible for the time the controller should wait after releasing the nozzle, the standard time for the nozzle in dual solenoid valve engines to return to the closed position is about **10-13 ms**. Therefore, it is not recommended to go below these values with the time for this function due to the fact that it can negatively affect the accuracy of the replica and the discharge speed.
