Bring your own tuner and your own laptop. We supply the dyno, the operator and the data.

IMPORTANT - ASSUMPTION OF RISK & RELEASE OF LIABILITY

I understand that dyno testing, custom or remote tuning, ECU/TCU flashing, datalogging, road testing, performance modification, and related services can place substantial stress on a vehicle and can expose, accelerate, or cause mechanical, electrical, drivetrain, tire/wheel, module/ECU, or other failures, including catastrophic failure, property damage, fire, loss of use, injury, or death. I represent that I own the vehicle or am authorized by its owner, have disclosed known defects and modifications, and voluntarily assume these risks.

For remote tuning, I accept the risks of inaccurate information, hardware/software incompatibility, interrupted flashing, communication or power loss, ECU/TCU corruption or “bricking,” recovery/towing costs, and Customer-controlled datalogging. I will operate and test the vehicle only safely and lawfully.

TO THE FULLEST EXTENT PERMITTED BY LAW, I RELEASE AND WAIVE CLAIMS AGAINST FASTUTV LLC D/B/A DEFI MOTORSPORTS AND ITS OWNERS, EMPLOYEES, TUNERS, TECHNICIANS, AGENTS, CONTRACTORS, AFFILIATES, AND INSURERS ARISING FROM THE INHERENT RISKS OF THE SERVICES OR THEIR ORDINARY NEGLIGENCE IN PERFORMING THE AUTHORIZED SERVICES.

I understand that DEFI does not guarantee horsepower, reliability, component life, drivability, emissions compliance, warranty coverage, or any particular result. I am responsible for legal/emissions compliance and for stopping vehicle operation if warning signs or abnormal conditions occur. This release does not waive liability or rights that applicable law does not permit to be waived. I have reviewed and agree to the full DEFI Motorsports Dyno Testing, Tuning & Performance Services Agreement, which is incorporated into this purchase/authorization.

From $999 per dayCell and operator. Bring your own calibrator, laptop and licenses

Detail of the Mainline ProHub dyno at DEFI Motorsports

How rental works

You book the cell, we run the equipment. Your calibrator works on their own laptop with their own software while we handle hub mounting, cooling, load control and data capture.

This is common for shops without their own dyno, calibrators travelling to a customer, and manufacturers validating a part. We do not require you to use our tuning services to use our dyno.

What is included

  • Mainline ProHub cell with operator
  • Load control and cooling
  • Full data capture and sheets for every run
  • Half-day and full-day blocks

What to bring

  • Your calibrator and their laptop
  • Your own licenses and interface hardware
  • Fuel for the session

What can be added, and what it costs

  • Additional dyno time$350 per hourCharged in hour blocks when a session runs past its booking.
  • Ignite Racing Fuel$80 per 5-gallon pailSupplied at the shop when the calibration calls for a fuel you did not arrive on.
  • Wideband monitoringIncludedExternal wideband on every session. Not an upsell — it is how the car is kept safe.

Common questions

Do you supply an operator?
Yes. The dyno is not self-serve — our operator runs the equipment for the whole session. That protects your vehicle and our cell.
Can I bring more than one car?
On a full day, usually. Tell us in advance so we can plan changeovers into the block rather than eating your time with them.
