how to prepare for
a chassis dyno test
chassis dyno checklist
When you arrive for your dyno appointment, we’ll conduct a basic visual inspection of your vehicle for fluid leaks, worn or deteriorated components, tire pressure, and loose or improperly fitted parts. Please note that this is a very basic inspection that will only reveal issues that are obvious and in plain sight.
Ultimately, you’re responsible for ensuring that your vehicle can withstand the rigours of running at high speeds and RPMs on the dynamometer. Any unresolved mechanical issues that may surface under heavy load should be repaired before your appointment. Otherwise, there’s a good chance your session will be interrupted, and you’ll have to reschedule the test.
We’ve created a detailed checklist for you to review before your testing appointment. Reviewing this checklist and making any needed repairs before your test will help ensure that your chassis dyno testing experience goes smoothly.

1. Sensors
Are any sensors faulty or not working? If yes, replace them in advance of the test. If your check engine light stays on, we can usually identify the problem through your ECU; however, certain issues may affect the consistency of your tune. Be sure to contact us in advance if you have a Check Engine warning light on.
2. Previous Tuning
3. Wiring
Ensure that your wiring is properly grounded and protected. Dyno testing and premium tuning of vehicles go smoother and quicker when all wiring is neat, tidy, properly grounded and protected from heat.
4. Engine Modifications
Call before your appointment if you have changed or plan to change/upgrade your: Fuel Injectors, Camshaft, Long-Tube Headers, or powerboost or supercharger.
5. Exhaust
Exhaust leaks can cause inconsistent tuning, and weak components can come apart during the rigours of the dyno test. Repair or replace any problem components – including loose or missing hangers. If your exhaust system is leaking, we may NOT be able to tune your vehicle – inspect your system carefully for leaks and repair them before your appointment. If you’ve added Exhaust Tips, ensure that they are fully sealed where they connect to the tailpipe.
6. Cooling System
7. Fuel Tank
Make sure your tank is at least half-full. For a consistent tune, fill up with the same octane fuel you routinely use. If your odometer’s over 80,000 km, we recommend changing the fuel filter.
8. Drivetrain
Is your drivetrain in good condition? An increase in power means more load on the drivetrain. Inspect your wheel bearings, driveshaft, suspension, U-joints, and CV-boots for signs of wear or deterioration and make any necessary repairs. Make sure your clutch is in good condition and not slipping.
9. Tires
Ensure that your tires are properly inflated and have an adequate amount of tread. If you plan to change rim or tire sizes, be sure to inform us before tuning.
10. Fluid Levels
Check your engine oil, coolant, transmission oil, and gear lubricant levels. A fresh oil change is recommended. If there are any fluid leaks, repair them in advance. We do not allow vehicles with fluid leaks into our shop.
