What is Stage 1 Engine Remapping?
Stage 1 engine remapping involves optimizing the original engine control unit (ECU) parameters to improve vehicle performance, without mechanical modifications.
This optimization acts on several elements:
torque management
boost pressure
injection
ignition (petrol engines)
torque and engine protection limits
What gains can be expected from Stage 1?
Gains vary depending on engine and powertrain:
Diesel: +20 to +35% torque, +15 to +30% power
Turbo petrol: +15 to +30% power
Naturally aspirated petrol: more moderate gains
Is Stage 1 remapping reliable?
Yes, provided it is done correctly.
