Frequently Asked Questions
What does an ECU remap do on the Renault Laguna 1.9 DCi 120hp ( 120 PS / 88 kW )?
An ECU remap (chiptuning) modifies the engine control unit software to optimise parameters like injection timing, turbo boost pressure and fuel delivery. On the 1.9 DCi 120hp ( 120 PS / 88 kW ), this typically results in more power, better throttle response and improved fuel efficiency at part load.
How much power gain is possible with Stage 1 on the 1.9 DCi 120hp ( 120 PS / 88 kW )?
Stage 1 brings the 1.9 DCi 120hp ( 120 PS / 88 kW ) from 120 PS to 150 PS — a gain of +30 PS. No hardware modifications are required, making it the most popular and cost-effective tuning option.
Is chiptuning reversible on the Renault Laguna?
Yes. We always save the original ECU file before applying any remap. The tuning can be fully reversed to factory settings at any time.
