Advanced Digital Control 

lockup-mate PLUS+ uses a micro-computer to listen to your car's internal digital CANBus via the OBD2 port to read important vehicle parameters.

 

Parameters include the accelerator pedal position, speed, RPM, current gear, 4WD mode, Sport or Drive mode, factory TCC lockup status, Sport gear, transmission temperature, slip, and even headlight status. 

The micro-computer at the heart of lockup-mate PLUS+ uses all this information to ensure the torque converter is locked whenever possible whilst maintaining great drivability and maximising lockup benefits.


Separate lockup algorithms for DRIVE (4H), SPORT (4H) and Low Range (4L) modes:
 

  • DRIVE

Ensures the gear changes have stabilised (for 5 seconds) before activating the lockup clutch.  Under light acceleration, the factory gear shift pattern will change gears too early to maintain lockup after the gear changes.  Waiting for the gears to stabilise prevents unnecessary lock/unlock operations during acceleration. 

  • SPORT

More aggressive lockup algorithm to give the driver more control over lockup.  Lockup can occur once the actual gear equals the chosen SPORT gear (eg, S2, S3) as there is no gear stabilisation delay like in DRIVE mode.

  • 4L (Low Range 4WD)

Uses the engine RPM as the key parameter to determine when to lock and unlock. The RPM ranges are adjustable to suit various driving conditions.  

 

The PWM signal to the lockup solenoid is controlled by the micro-computer and mimics the factory computer for smooth activation and reliability.

The Excessive Slip Alert feature will flash the LED after 10 seconds of excessive torque converter slip (when unlocked) and as an alert to change to a lower gear to maintain lockup conditions.  This alert feature is user configurable, and can be switched OFF, be ON only in SPORT mode, or be ON in both DRIVE and SPORT modes.

lockup-mate PLUS+ will only activate once the transmission has reached the warmup temperature (default is 30 degC).  While waiting for warmup the LED will gently pulse so the driver knows it's not active.  The warmup temperature can be adjusted between 20-90 degrees.  This feature also allows lockup-mate PLUS+ to be configured if the user only wants to protect the transmission from high temperatures (eg >90 degC), and keep the normal factory operation otherwise.  The warmup LED pulse can be switched off when used in this way. 

No-one likes a bright LED in their face during the night, so lockup-mate PLUS+ monitors the headlight status so when they are switched on the LED automatically dims.  This can be over-ridden when driving in daylight with your headlights on by simply holding the LED/switch down for 5 seconds to toggle this mode.
