MAHA 4-Wheel Dyno Testing
Our MAHA 4-wheel rolling road gives accurate, real-world power and torque figures from all four wheels simultaneously — not an estimate, not a manufacturer claim, but a measured result specific to your vehicle on the day.
Whether you want to verify remap gains, diagnose an unexplained power loss, set up a competition car, or simply find out what your vehicle actually produces, our in-house MAHA dyno is one of the only 4-wheel setups of its kind in South Wales.
Why EC Performance
Accurate, all-drivetrain testing in-house — not outsourced, not a 2-wheel-only rig.
Unlike many 2-wheel rigs, our MAHA dyno tests AWD, 4WD, FWD and RWD vehicles accurately, powering all four wheels simultaneously for a true representation of real-world output.
MAHA is trusted by professional motorsport teams worldwide, giving you confidence that the figures produced are genuinely accurate, not just indicative.
We're one of the only operators in South Wales with an in-house 4-wheel dyno, meaning testing, tuning and diagnosis all happen under one roof without outsourcing.
Every remap we carry out can be verified with before-and-after dyno runs, so gains are measured and proven rather than simply claimed.
What's Included
The range of MAHA 4-wheel dyno services available at our Ammanford workshop.
Baseline power and torque runs before a remap, and verification runs after, so you can see exactly what your ECU remapping service has delivered in hard numbers.
If your vehicle feels down on power but nothing obvious shows up in diagnostics, a dyno run can help pinpoint where in the rev range the loss is occurring to guide further investigation.
Boost and lambda monitoring alongside power/torque data, useful for setting up and calibrating a competition-focused build to a known baseline.
Every session can be supplied with printed or digital power and torque graphs, giving you a permanent record of your vehicle's measured output.
Also available: back-to-back tuning sessions, competition calibration, and full data logging packages.
FAQ
Yes, dyno runs are by appointment. Get in touch and we'll find a slot, and can combine tuning and dyno work into one visit if you're also having a remap.
Yes — our MAHA dyno has full 4WD capability, meaning AWD, 4WD, FWD and RWD vehicles can all be tested accurately from all four wheels simultaneously.
Power and torque figures in BHP and Nm, available as printed or digital graphs, with boost and lambda data logged where relevant.
Yes, a dyno run can help pinpoint exactly where in the rev range a power loss is occurring, which is useful supporting evidence alongside standard diagnostics.
No, you can book a standalone dyno run simply to find out what your vehicle currently produces, with or without any tuning work being carried out.
