The technical workflow behind every calibration
Understand what Stage 1, Stage 2, eco, and deactivation calibrations actually involve — hardware, process, and expected outcomes.
How a RazTech calibration works
Every file is manually modified by a dedicated ECU engineer — no automated solutions. You read the original file with your tool, upload it, and receive your tuned file in under 1 hour during operating hours.
Stage 1 — Performance Calibration
Software-only calibration for a stock vehicle. The most popular, safest upgrade.
Hardware requirements
None required — stock vehicle.
Process
- Read the original ECU file via OBD or Bench
- Manually adjust boost, fuel, and ignition maps
- Smooth torque delivery for drivability
- Road-test for DTCs
Expected outcome
Typical gains of +20-40hp and +40-80Nm with no hardware changes. Safe for daily driving.
Stage 2 — Performance Calibration
Calibration for vehicles with supporting hardware upgrades (intake, downpipe, intercooler).
Hardware requirements
Upgraded intake, downpipe/de-cat, and upgraded intercooler recommended.
Process
- Confirm installed hardware with the customer
- Read the ECU and scale maps for the new airflow
- Tune for higher-octane fuel with safety margins
- Set recommended service intervals
Expected outcome
Maximum safe power on stock internals. Gains of +50-100hp depending on hardware and platform.
Eco & Fuel Efficiency Tuning
Torque-focused calibration that improves fuel economy without sacrificing reliability.
Hardware requirements
None required — stock vehicle.
Process
- Read the original ECU file
- Optimize injection timing and rail pressure at mid-load
- Increase low-end torque to maintain cruising performance
- Verify consumption under load cycles
Expected outcome
Typical fuel savings of 8-12% with improved low-end drivability. Ideal for fleets and long-distance drivers.
Deactivations (DPF / EGR / AdBlue / Vmax)
Software deactivation of emissions systems — strictly for track, off-road, or motorsport use.
Hardware requirements
Physical removal optional but not required for software deactivation.
Process
- Read the ECU in Bench or Boot mode
- Disable the relevant regeneration/dosing/monitoring routines
- Clear all related fault codes from the calibration
- Customer signs a track-use disclaimer before delivery
Expected outcome
Removes the targeted system at the software level with no recurring fault codes. Track/off-road use only — not road-legal.
Emissions-related deactivations (DPF, EGR, AdBlue/SCR, Vmax) are supplied strictly for track, off-road, or motorsport use only. These modifications may render a vehicle non-compliant for road use. The customer assumes full legal responsibility. See our Terms of Service.
