About this remap

Renault Scenic 1.5 DCI EU4 85 hp Stage 1 — what changes

The Renault Scenic 1.5 DCI EU4 85 hp (2003–) leaves the factory at 86 BHP and 199 Nm of torque. Manufacturers deliberately detune this engine to separate it from more expensive variants in the range — a Regal Tuning Stage 1 calibration safely recovers that headroom through the ECU alone: no hardware changes, no dyno risk, fully reversible.

Fuelling, boost pressure, ignition and torque limiters are optimised within the safe tolerances of the 1.5 DCI EU4 85 hp powertrain (diesel). The result is 111 BHP and 296 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
