1. Introduction

Your firmware image runs unchanged, instruction by instruction, on an emulated ECU processor. Around it is a model of the whole car, so the ECU reads its sensors and drives its actuators as it would on the road:

• Engine — airflow, fuelling and torque, with ignition timing on petrol engines and injection on diesels; on turbocharged engines, boost with turbo spool-up and the wastegate or variable-geometry vanes driven by the ECU.
• Heat — coolant, oil, intercooler, thermostat and fan warm up and cool down during the run.
• Driveline — the gearbox with its clutches, torque converter or hybrid motor, road load, tyre grip and wheel slip, with the mass and gear ratios of the car.
• ECU decisions — torque limits, boost targets, smoke limits, ignition retard on knock, rev and fuel cuts and fault codes come from the calibration you uploaded, not from the model.

The virtual dyno is included with an active TCEPro license at no extra cost. Open it in the cabinet: Virtual dyno. Without an active license the cabinet shows how to get one: the license turns on with the first catalog purchase.

What the service does, the supported vehicles and the latest runs are also on the public page Virtual dyno.

A tuned image is accepted when it is based on the same software (Program ID) as a supported image (§2.3). The list grows as new vehicle models are prepared; the current one is on the public page.
