  • Sequentially illuminated high intensity LED's allow the driver to perfectly time up shifts
  • Shift light levels set to the nearest 10 RPM
  • Ultra bright LED's can be clearly seen in the brightest sunlight and brightness is adjustable to prevent dazzle at night
  • LED array "strobes" at the shift point for maximum impact
  • Multiple colour LED array helps the driver establish RPM at critical points on the track
  • Low RPM warning LED instantly warns that driver when he is out of the power band
  • Connects to SmartMax Tachometer module through a 1.8 Metre (6') flying lead terminated with a 7 pin connector


SmartMax Tachometer Module

  • Records Smart Max RPM and Peak RPM values
  • Automatic save, and simple recall, of the last 4 SmartMax and Peak RPM Telltale values
  • Integrated key pad
  • Separate ready wired power loom with positive lock connector to plug into the Tachometer Module
  • Simple 3 wire "No hassle" hook up
  • Module can be disconnected and removed from the vehicle in seconds
  • Non volatile memory means all settings and readings are saved even if power is removed
  • Performance will not deteriorate over life of product



Normal Use

The SmartMax Tachometer Module integrates a 16 character LCD readout and key pad.

In normal operation the Control Module provides a high accuracy readout of the current engine RPM and at the press of a key the Max. RPM values for the last run are recalled.

Using the keypad, the SmartMax RPM & Peak RPM for the last run can be displayed on the LCD. Max RPM values for the previous 3 saved runs can also be recalled at the press of a key.


The system can be programmed with 6 different configuration profiles to allow the user to quickly change between different vehicle or driver setups.

For each profile the following parameters can be set using the keypad:

  • Shift down / Low RPM Level
  • First Pre-shift Warning Level
  • Shift RPM Level
    (Intermediate shift light RPMs are set automatically at equal stages between the First Pre-shift and Shift RPM levels)
  • Number of Engine Cylinders
  • SmartMax filter value
  • Flashing or constant LEDs at shift RPM
  • LED brightness (6 levels + off)

As the settings are stored in non volatile memory, the system will not lose its configuration profiles or Telltale readings when power is removed.

The profiles and readings can therefore be changed or reviewed with the unit removed from the vehicle if required.



The Shiftlight and Tachometer Modules are designed to be fixed into the vehicle using "Dual Lock" * (supplied) and can be easily removed and refitted as often as required.

The Satellite Shiftlight Module should be positioned in the drivers field of vision and its pre-terminated lead connected into the Tachometer Module. The lead has a pre-fitted rubber grommet so that if it is fed through a bulkhead the hole can be correctly plugged.

Control Module fitted to Kart

An example of robustness, the above unit had earlier broken free of its mounting and was dragged by its cables down the track at racing speeds!  The unit still functioned fine and no repair was necessary.

A pre-terminated power loom is supplied which is simply hooked up to a 12V supply, a good ground point and a coil negative or tacho output; and connects into the Tachometer Module.

Note: Although this system is designed for use in a racing environment, the control module should be installed so that it is not exposed to direct water spray.

* Dual Lock is a registered Trade Mark of the 3M Company
