You press the pedal and wait. Modern drive-by-wire cars soften the signal between your foot and the throttle body so the car feels smooth and predictable in traffic. On a car you bought for the way it drives, that dead spot at the top of the pedal gets old fast.
The Dinan Throttle Booster plugs in between your accelerator pedal and the engine computer and reshapes that signal. Pick one of 5 preset throttle curves from the wireless switch, or build your own in the Dinan app and save up to 3 custom curves to the device. It fits BMW, MINI and Toyota GR Supra models, and it works on stock or modified cars.
How the Dinan Throttle Booster Changes Pedal Feel
It does not add horsepower and it does not change your engine tune. What it changes is how quickly the car responds to your right foot. Choose a sharper curve and the car answers the moment you touch the pedal. Choose a softer one for rain or a long commute. The wireless switch lets you change modes on the fly without reaching for your phone, and the iOS and Android apps let you fine-tune curves until the pedal feels exactly the way you want.
Dinan Throttle Booster Install and Legal Status
The booster connects at the accelerator pedal harness with plug-in connectors. Nothing is cut or spliced, and it unplugs completely if you ever want to return to stock. Dinan rates the install at about 15 minutes, though tight footwells can take longer. Before you order, know this: it is not legal for sale or use in the State of California. It is legal in other states under the EPA Tampering Policy, and CARB testing is pending with no Executive Order number issued yet. Dinan backs it with a 30 day money back guarantee if you are not satisfied. Dinan part number D440-1700. Sold by AutoTecknic, an authorized Dinan dealer.

Vehicle Fitment
Dinan lists the Throttle Booster for these vehicle families:
- BMW: 2000 and newer models
- MINI: 2002 and newer models
- Toyota GR Supra / A90, A91 (2020-2026)
E38, E39, E46 and E53 BMW and first-generation MINI need extra care at install because the pedal adapter plate on those cars is fragile. Pedal connectors vary by model, so send us your VIN and we will confirm fitment before you order.
Installation Notes
Most owners can do this in their driveway with basic hand tools. Plan on 15 minutes to an hour depending on how much trim has to come off around your pedal box.
- Remove the driver floor mat and the lower dash or pedal cover panel.
- Unplug the factory connector from the accelerator pedal.
- Plug the Dinan harness in between the pedal and the factory connector.
- Mount the booster module with the supplied zip ties, clear of the pedal's full range of travel.
- Refit the trim, confirm full pedal travel, then pair the wireless switch and app using the Quick Start Guide.
