MACE recalibrated ECM Tune to suit:

VZ VE V6 Alloytecs and LLT SIDI engines,

Holden Rodeo/Colorado 3.6L & Holden Captiva 3.2L


We require your PCM (if your vehicle is an auto your TCM as well) to be sent up to us for this recalibration process, which is normally a 1-4 day turn around. Once recalibrated, it's posted off via Australia Post Platinum Express for speedy safe delivery.



  • Average 10rwkW power gains
  • Increased torque
  • Increased fuel economy
  • Improved throttle response
  • Easy 15-minute DIY installation


Installed all bolt-on'€™s and still want more power? Want to clear an annoying error code due to installing high flow cats? Then this cost effective upgrade is for you.


Each ECM (Engine control module) is recalibrated to suit your specific engine and mods (within reason). All you need to do is fill out the supplied form and send off your computer for us to recalibrate accordingly. Once your ECM is recalibrated, it'€™s then posted off via Australia Post Platinum Express for speedy safe delivery

Horsepower gains vary between different models, fuels and the condition of your particular engine. Generally though, average gains of around 10rwkw are common

Fuel economy gains will also vary between different models and the condition of your engine. Our conservative estimate is an extra 30 to 50kms to a tank.


Our performance ECMs feature recalibrated fuel, ignition and cam timing parameters, this means your motor will operate much more efficiently.

By adjusting these maps within the program of your Commodore ECM, we fix the mass-production compromises Holden originally made.


Larger horsepower gains are possible when our performance ECM are used in conjunction with a free-flowing exhaust and a cold-air intake system. CLICK HERE to view our range of cold-air intakes for Commodores.

Make sure you clean your MAF sensor is clean before installing your upgraded ECM. Cleaning your MAF sensor should be done on a regular basis to keep your car's performance at its best.


  • The image is for illustrative purposes only.
  • Our performance ECMs are not suitable for forced induction applications. If you have a highly modified engine or are running a custom supercharged or turbocharged setup, you require a custom one-off tune. If you are in doubt, please don't hesitate to contact us.
