How much does the 1.8 TCe take?
It is a turbocharged petrol with genuine headroom and responds well to a Stage 1 map on standard hardware.
How does it differ from the Mégane III RS?
They are consecutive generations of the same hot hatch, with different engines and ECUs. Each has its own entry.
What is Stage 2 for?
It is for cars that already carry hardware modifications, typically exhaust or intake. Without them, Stage 1 is the right level.
