JMF Mechanical and Fabrication Across Southern Highlands
Southern Highlands ECU Tuning Specialists
JMF Mechanical and Fabrication has been tuning and building engines for more than 35 years. Petrol or diesel, daily driver or weekend build, we tune for the way you actually use the vehicle.
A good tune isn’t about chasing the biggest number on a dyno. It’s about getting real power and sharper response without giving up reliability. That’s the work we do, and it’s the work we stand behind.

JMF Mechanical and Fabrication
Tuning You Can Trust
There’s a right way and a wrong way to tune an engine. The wrong way gets you a number on a dyno and a vehicle that won’t last. The right way gets you real power, sharp response, and an engine that still runs well in the years to come.
JMF Mechanical and Fabrication tunes for the long run. We set realistic targets, match the tune to your engine, and pull the most out of your vehicle without taking life off it. That’s the difference between a tune that lasts and one that doesn’t.
