A successful remote dyno session requires a mechanically sound vehicle, a properly equipped facility and clear communication between the operator and calibrator. Scheduled dyno time should not be used to diagnose unresolved mechanical problems.
Dyno-facility requirements
- Proper exhaust evacuation
- High-capacity radiator and intercooler airflow
- Safe vehicle restraint
- Reliable RPM and power measurement
- Stable internet and AC laptop power
- A qualified dyno operator
A small household fan is not adequate for sustained dyno operation.
Vehicle preparation
- No fuel, oil, coolant, exhaust or boost leaks
- Healthy battery and charging system
- Fresh, correctly specified spark plugs
- Correct fluids and safe tires
- Known fuel and measured ethanol content when applicable
- Correct software, cables, adapters and licenses
- Completed pre-dyno mechanical inspection
File organization
Label every log and dyno file with the customer or vehicle, calibration revision, fuel and ethanol content, drive mode, gear, dyno run-file number and a brief description. When requested, overlay only the latest run and the immediately preceding run.
Session procedure
- Kassel specifies the starting RPM, ending RPM, gear and mode.
- The operator performs the requested run.
- Send the matching datalog, dyno graph and calibration where applicable.
- Allow Kassel to review the data.
- Load the approved revision.
- Cool the vehicle as directed.
- Repeat only after Kassel authorizes the next run.
Stop immediately for abnormal noise, smoke, leakage, pressure loss, misfire or unexpected data.
