ECU Tuning Estimates vs Measured Results

How to interpret Stage 1 reference figures, normalised charts, dyno measurements, logs and real-world variation.

The configurator is a qualification tool, not a dyno report. Its figures help a workshop understand a possible range before BLAG has reviewed the exact ECU file and application.

What an indicative figure means

A database reference may combine available technical sources and normalised values for a vehicle/engine description. It cannot know the precise software, tolerances, fuel, environment, dyno type, transmission loss, mechanical condition or safe limit of the vehicle in front of you.

What a dyno result means

A dyno measurement belongs to a specific vehicle, test equipment, correction method, gear, tyre condition, temperature and operator procedure. Results from different dynos or conditions are not automatically comparable. “Before” and “after” should use the same controlled method.

Reference database

Useful for enquiry qualification and identifying a plausible starting range.

Normalised chart

A visual comparison, not a recorded engine or wheel-power run.

Data log

Shows selected ECU channels under stated conditions; it is not a power measurement by itself.

Dyno or load test

Measures behaviour using identified equipment and a repeatable procedure.

How to communicate responsibly

  • Call database values indicative.
  • Do not advertise a guaranteed gain before reviewing the original and condition.
  • State whether a result is crank estimate, wheel measurement or another method.
  • Keep before/after conditions comparable.
  • Record limitations and safe operating constraints.

Use the configurator correctly

Find the reference, then submit the original file for a vehicle-specific decision.

Frequently asked questions

Are Stage 1 figures in the configurator guaranteed?

No. They are indicative references. The exact software, hardware, condition, fuel, environment and safe limits affect final feasibility.

Is the displayed curve a dyno graph?

No. It is a normalised visual comparison and is labeled as such.

Can two dyno results be compared directly?

Only when equipment, correction, gear, conditions and procedure make the tests meaningfully comparable.
