Works in harmony with the transmission ECU
lockup-mate®PLUS+ works in harmony with the factory transmission Electronic Control Unit (ECU) to use the standard flex-lockup and full-lockup modes. It will also take over full-lockup control when required.
With its advanced micro-computer controlled intelligence and constant communication with the ECU, lockup-mate®PLUS+ exchanges control of the TCC back and forth with the transmission ECU. Essentially, lockup-mate®PLUS+ and the ECU are collaboratively working together to control the TCC.
For example, when the ECU wants to fully lock, lockup-mate®PLUS+ will hand over control to the ECU so that it drives the TCC solenoid. This avoids the load resistor becoming hot. If the ECU then wants to unlock due to a slight hill climb, lockup-mate®PLUS+ will step in and over-ride it to keep the TCC locked.
lockup-mate®PLUS+ will light the LED so the driver knows when the lockup clutch is activated. The LED is located on the A-pillar so it can be easily seen whilst driving.
The lockup-mate®PLUS+ micro-computer controls the PWM signal to the lockup clutch solenoid to mimic the ECU to ensure smooth and reliable operation. It even ensures a smooth transition from the ECU's flex-lockup mode to the when lockup-mate®PLUS+ initiates full-lockup mode.
