Dyno Tuning

Show Navigation Menu


MRT tunes more than Subaru, Mazda or Mitsubishi!

Almost any model car with any model ECU.
Our Dyno cell, is the best in Sydney and the most advanced in Australia. So advanced that many other workshops use it!
With huge airflow (22,000 cfm!) it can empty the room in 5 seconds, meaning we get a very consistent tuning environment.
We also have a separated (dedicated) cooling fan for intercoolers mounted on top of engines on cars such as:

  • Subaru
  • Mazda 3
The benefit is we have consistent intercooler temperatures as well. 

The staff at MRT Performance pride themselves on the success of vehicles we have tuned over many years. This includes hundreds of private owners road cars and many competition cars. With results such as:

  • Outright success in Targa Tasmania (Tony Sullens).
  • 2004 GT Production champions Protecnica Racing. (Justin Hemmes).
  • Targa New Zealand 5th outright, Steven Richards.
  • Osborne and Grand Prix Mazda race teams. 
  • and many, many satisfied road car clients

We also do all the local development of ECU Maps for the EcuTeK range of factory ECU tuning products. Click here for information
All our tuning is done exclusively on a Dyna Pack Dyno, the most accurate and repeatable Dyno available.

Our dyno can be used for:

  • Tuning a cars ECU.
  • A simple power and Torque plot to record your cars performance.
  • Checking fuel mixture's.
  • Adjusting boost controllers.
  • Comparing and testing parts such as, exhausts, different engine oils, turbo's etc.
  • Checking the cars suspension, yes with our Dyno we have full access to the suspension whilst the car is being "driven".

Dyno Graphs

There are many ways to review a dyno graph, or "plot" or such. Many brands of Dyno's display data and varied ways, its important you know what to look for. Also also VITAL that you compare "apples with apples" as Dyno's vary so does their results. For more data click this link.
Also refer more information on how top read Dyno Data in the Subaru performance Handbook

Comparing Dyno data

Dyna Pack, Mainline, Dyno Dynamics and more, all these dyno brands vary in the way they display data and information. One main exception is Dyna Pack is a hub dyno and all the others are roller dynos.
As a general rule a roller dyno reads lower than a hub dyno due to the parasitic loss's of the tyre, wheel interface.
The higher the power of the car the greater the difference. 

Hub Benefits

  • Bolts directly to the cars hubs /axles so it has no variation or loss caused by wheels and tyres.
    (tyres, tread, pressure, wheel diameter all effect dyno results on roller dyno's)
  • Measures "real" Torque as measured in Nm
    (roller dynos only display "tractive effort")
  • Absolutely no wheel spin. Saves tyre wear!
    (all roller dyno's have wheel spin, more power means even  more wheel spin) 
  • Does not need to be "tied down"
    (saves time most notably with high power cars that need major tie down straps on roller dyno's)
  • No inertia. 
    (no need to use cars brakes to slow down rollers after a power run) 
  • Can do more tuning in less time 
    (as soon as the clutch is pressed the cars axles stop spinning) 
  • Quieter
    (no tyres means heaps quieter so your cars engine is easier to listen to) 

Hub Disadvantages

  • On (low power) cars when compared to roller dynos, takes longer to get on an off Dyno
  • Some modified race cars can not "fit" the hub / pod design of a hub dyno.

Roller advantages

  • No need to remove wheels.
  • Low power cars are quicker to get on and off.
    (when compared to a hub dyno) 

Roller Disadvantages

  • Tyre wear (caused by wheelspin)
  • Not as accurate due
    to wheelspin
    tyre stickyness
    tyre varying diameter
  • Noise
  • Dirty, all that tyre rubber ends up a black soot
  • On high HP cars tyres can fail due to distortion under high load on the sidewalls
  • Can not (as easy) inspect brakes, suspension and chassis whilst in use
