Virtual Dyno

Power-trend visibility inside the same tuning workflow.

Virtual Dyno helps you compare power trends between logged pulls. Results are estimates that depend on accurate vehicle settings and consistent test conditions; use a suitable closed course or controlled test facility.

What this page should communicate
PulseWidth uses one telemetry-first visual language across public storytelling and operational product surfaces.
Virtual Dyno belongs in that story because it reinforces the connection between flashing, logging, and iterative calibration decisions.
It should not claim universal availability or replace the pricing and login paths that repeat users actually need.
Automatic pull capture

PulseWidth watches the same live data stream used for tuning and logging, so the dyno workflow starts from the current ECU session instead of a separate tool.

Run-over-run comparison

Overlay pulls, compare deltas, and look for gains or losses without leaving the same telemetry-driven product surface.

Safety context

Virtual dyno is most useful when it is read alongside knock, boost, AFR, and the rest of the logging context already flowing through the session.

Power and torque trend overlays for repeat comparison
Linked context for boost, AFR, and knock review
Street-pull iteration support during live tuning sessions
Availability follows current tier and rollout status
Accuracy note
Treat street pulls as tuning context, not final certification.

A street-derived power view is valuable for iterative decision-making, especially when you can compare runs immediately after a change. It is still different from a controlled chassis dyno environment.

That distinction fits PulseWidth's broader product framing: useful capability now, honest boundaries where precision or support scope still depends on vehicle, environment, or rollout state.
