Dyno Tuning - Dynocom 15000FX

The Dynocom 15000FX (AWD GDFX architecture) is a high-capacity chassis dynamometer built for serious performance calibration. Manufacturer specifications for the 15,000-series platform include:

• Speed capability: up to 240+ mph (386+ km/h) roller speed
• Power capacity: up to 4,400+ hp in AWD configuration (2,400+ hp per axle class)
• Axle load: up to 14,000 lb (≈ 6,350 kg) maximum axle weight
• Track width: typically 30–102 in overall; AWD linked rear section 36–86 in
• Rollers: 24 in diameter × 36 in width drums with X-Factor knurling for maximum tyre traction under load
• Measurement accuracy: drum speed ±1/1000 mph; RPM ±1/100; timing ±0.1 µs (platform class)
• GDFX gearbox linkage: front and rear rollers locked to the same road speed - prevents false traction-control intervention and keeps AWD torque management in a valid operating state
• Load cell path: optional centre-mounted eddy retarder sits directly on the shaft between rolls (no belt/U-joint losses) for steady-state load control - up to ~850+ hp additional absorbed load / ~2,300+ ft·lb torque class per retarder
• Control hardware: Dynocom DC-Controller with differential analogue inputs, atmospheric module (humidity, barometric pressure, temperature) and integrated wideband A/F capability

This is the hardware we use to develop and prove calibrations - not a showroom display dyno for a single printed graph.

Sustained dyno tuning generates heat in the engine bay, charge-air path and exhaust. Our cell uses two industrial axial fans directed at the vehicle. Each fan is rated up to 186,500 m³/h (51.8 m³/s), giving a combined cooling capacity of up to 373,000 m³/h (103.6 m³/s) across the radiator, intercooler and engine bay.

• Diameter range: 315–1600 mm
• Volume (per fan): up to 186,500 m³/h (51.8 m³/s)
• Combined (2 fans): up to 373,000 m³/h (103.6 m³/s)
• Static pressure: up to 2400 Pa
• Test standards: ISO 5801 and BS 848
• Motor protection: IP55
• High energy efficiency with low installed noise levels

That volume of air keeps charge temperatures stable between loaded pulls so air-fuel and boost data stay repeatable in Quantum. Without it, intake temps climb and calibration iterations become meaningless.

Quantum is the control and analysis brain of the Dynocom system. During a dyno tune we use it to command load, capture channels and compare iterations in one place:

• Atmospheric correction: SAE J1349, DIN and EEC correction formulas so power/torque comparisons remain meaningful across ambient conditions
• Unified ECU logging: overlay dyno channels with third-party ECU data streams (including platforms such as HP Tuners, Haltech, AEM and similar) for true closed-loop calibration work
• Virtual road simulation: applies eddy-brake load from vehicle mass, frontal area, drag coefficient and tyre rolling resistance - so final fine-tune can be completed under simulated road load rather than open-loop pulls alone
• Load modes: constant-load, step, slope and PID-enhanced load control for steady-state mapping of boost, AFR and torque targets
• Graph & data views: multi-axis graphing, customisable gauge templates, channel filtering/scaling, and export to common image/data formats
• Run database: archive and search sessions by vehicle, peak power/torque and customer parameters for repeatable development of our dyno-proven file library

In short: Quantum lets us see wheel power, torque, AFR and ECU live data together while we write the map - that is dyno tuning, not a pass-and-print test.

24Tuning calibrations are developed in-house. Where a strategy has been refined on the Dynocom 15000FX under Quantum logging, those files are dyno proven - boost targets, torque limits and fuelling tables validated under controlled load with cooling and atmospheric correction applied.

That same proven base data underpins our Stage 1 and Stage 2 mobile remaps. When you book a mobile flash, you benefit from calibration work that has already been exercised on this rolling road. A full on-cell dyno tune is the next level: your specific vehicle, hardware and fuelling are calibrated live on the Dynocom with iterative loaded runs until the map is finished.

• Full session on the Dynocom 15000FX with Quantum data acquisition
• Loaded calibration development (not a single “test only” pull)
• up to 373,000 m³/h axial cooling airflow throughout the session
• Power, torque and fuelling analysis under corrected atmospheric conditions
• Custom map refined on your vehicle / hardware combination
• Dyno-proven calibration retained for your vehicle file set

Pricing starts from £900. Exact scope depends on drivetrain, power goals and modifications - confirm details when you email to join the waiting list.

Demand for Dynocom cell time far exceeds available slots. There is currently a 12-month waiting list for dyno tuning. We do not take online bookings for this service.
