PERFORMANCE
REPORT.
Your vehicle. Your driving. Measured.
Real-world engine data.
Tailored ECU calibration.
Verified before and after.
WHY ROAD DATA MATTERS
A DYNO PROVIDES CONTROL.
THE ROAD PROVIDES CONTEXT.
Cold starts, traffic, motorway driving, repeated acceleration and real engine load reveal behaviour that a single workshop session cannot. GRIME combines both environments before making a final assessment.
THE GRIME METHOD
RECORD → ASSESS → OPTIMISE → VERIFY → REPORT
- 01
RECORD
The Grime Box records normal driving, cold starts, thermal behaviour and qualified load events for 5–7 days.
- 02
ASSESS
We review engine health and data quality before additional load or calibration work is approved.
- 03
OPTIMISE
Dyno measurements and real-use observations inform a tailored ECU calibration for the vehicle and its intended use.
- 04
VERIFY
A second road period checks response, control accuracy and thermal behaviour outside the dyno environment.
- 05
REPORT
You receive a technical record of what was measured, changed and verified — including limitations and next actions.
ENGINE HEALTH FIRST
NO CALIBRATION WITHOUT A BASELINE.
If the data indicates a mechanical, thermal or control-system issue, tuning stops. We review the evidence and agree the next decision with you before placing additional load on the vehicle.

- ENGINEERING CONCLUSION
- Measured change, limitations and recommended next action
SAMPLE REPORT / GR-2026-014
EVERY VALUE HAS A SOURCE.
Dyno measurements, ECU signals, calculated values and technician assessments are identified separately. Unavailable data stays unavailable — it is never replaced by a guess.
