Looking to improve the performance of your diesel engine?
Want to reduce the low down lag when taking off or overtaking?

There’s a simple answer, Fit a diesel chip!

What’s not so simple is which make to choose, & where to buy.

There are a numerous companies selling diesel chips in Australia, & there's a fair bit of misleading information around, along with some exaggerated claims.  So how do you know which one is best for your vehicle?


SMART TECHNOLOGY:  Inside a Tunit module is a State of the Art 32 bit microprocessor (mini computer) which continually monitors the engine’s performance, & modifies the fuel injection parameters.

OPTIMISES FUEL PARAMETERS:  It works by optimising fuel volume, fuel timing, & fuel pressure.  This process enhances a diesel engine’s performance by careful interplay of these values and characteristics, resulting in its optimum performance.

SAFELY BEHIND THE ECU:  Fuel pressure is increased, as this is necessary to atomise the increased diesel volume, and to burn the diesel more efficiently.  However, we do emphasise that this is all don’t within the vehicle manufacturers pre-set tolerances, as the Tunit module is connected into the fuel management system, behind the ECU which strictly controls these functions.

WE DO NOT CHANGE BOOST:  On Turbo Diesel engines the boost pressure of the turbo is not directly altered by the Tunit, although it may be slightly increased via the natural increase of exhaust gases provided by the increased performance.

MANUAL ADJUSTER:  V-CR & V-VP models have a 10 setting adjustment dial so that owners can adjust the unit.  Zero turns the unit off, & at the other end of the scale, 9 is for maximum performance.  Each Tunit is set at 5 when purchased.  For more power and torque the module can be easily adjusted as it can be if you were chasing fuel economy.
