Bought a car and don’t know if it’s standard?
Maybe you’ve tried sensors, diagnostics, parts and repairs — but the vehicle still isn’t behaving as it should.
👉 The software could be the problem.
We can check the vehicle and, where appropriate, return the ECU software to a genuine stock calibration using the correct equipment.
🚘 Are you a motor trader?
Before selling a vehicle, do you really know what’s inside the ECU?
If aftermarket software has been fitted, we can help establish what’s been done and advise whether returning the vehicle to standard is the right option.
Don’t spend hours chasing a fault that could be caused by poor or incorrect software.
