Evo7 — Stage 2 ECU Tune
- 260kW power output achieved
- Flex fuel tuning capability
- Optimized engine control management
- Enhanced turbocharger performance
This Stage 2 file was built for a 2002 Evo7 with a fresh internal build and larger turbo, designed to run both pump 98 and E85 depending on availability. The workshop recorded 260 kW at the wheels and 420 Nm of torque on their dyno, up from 214.7 kW and 310 Nm baseline. The calibration manages the full flex fuel range with appropriate ignition and fuelling adjustments across both blends.
The built bottom end provides headroom, and the larger turbo delivers the extra airflow needed to reach these numbers safely. Fuelling was dialled in for both ethanol content extremes, and timing maps were tailored to prevent knock on 98 while taking full advantage of E85's cooling and octane benefits when available. Intended for off-road and closed-circuit competition use.
Does the flex fuel calibration require any additional hardware beyond the turbo and engine build?
The file assumes the vehicle is equipped with an appropriate flex fuel sensor and supporting injectors. Those details are covered in the modifications list on the full spec sheet.
What kind of power difference can I expect between 98 RON and E85 with this file?
Peak power and torque will vary depending on ethanol content. The calibration adjusts fuelling and timing dynamically, with E85 typically allowing more aggressive ignition timing and higher output than straight 98 RON.
Is this suitable for a street-driven Evo with similar mods?
This file is intended for off-road and competition use. The power level requires a built engine and supporting fuel system as specified.
