Factory ECU tuning, done properly.
What is a PCMTEC Custom OS?
A PCMTEC Custom OS changes how the factory ECU behaves — not just how much power it makes.
Instead of forcing your build to work around factory logic, we customise the ECU software to suit your setup and how you actually drive the car
What Can Be Customised?
• Driver-selectable tune modes
• Flex fuel (98 / E85)
• Boost control strategies
• Track & drift features
• Factory system removal where required
Street Cars
Smooth drivability, factory manners, no warning lights — tuned to suit daily use.
Drift / Track Cars
Consistent power delivery, predictable throttle response, and limp-mode prevention for track use.
Multi-Fuel Builds
Run pump fuel daily, switch to E85 when you want maximum performance.
Engine Swaps
Standalone-style operation using factory ECU hardware, without factory dependencies.
Why This Matters
A Custom OS ensures your ECU logic matches your build and driving style, not the other way around.
