Looking for the best throttle controller for your Hyundai? The Stealth 4.0 DigiPedal throttle controller sharpens pedal response and reduces throttle lag.
Stealth 4.0 Digipedal + HP Tune for Hyundai
Not just a throttle controller. The Stealth 4.0 Digipedal removes throttle lag and can add power: typical gains are 3-5% (4 cyl 4-5 HP, 6 cyl 5-10 HP, 8 cyl 10-20 HP). It is calibrated to your vehicle model, so we need your details before we send it.
What does a throttle controller do?
Most modern cars have no throttle cable. When you press the accelerator, a sensor in the pedal sends a signal to the engine computer (ECU), and the ECU decides how far to open the throttle. To meet emissions, fuel economy and safety targets, manufacturers set the ECU to open the throttle slowly and softly. That is the delay or "lag" you feel when you press the pedal.
The Stealth 4.0 Digipedal sits between the pedal and the ECU. It reads the pedal signal and sends the ECU a sharper, more sensitive version of it. The throttle opens sooner for the same pedal movement, so the engine responds faster. On turbo cars it also helps reduce turbo lag. It does not change your ECU or engine, and it can be unplugged and removed at any time.
Instant response: less delay between your foot and the engine.
Pick how it feels: Eco for city driving, Standard (factory), Sport and Sport+ for performance driving.
Extra modes: anti-abuse, anti-theft (disables the pedal) and a voltage meter.
HP Tune: with the optional tuning wire, the controller also adds more HP (typically 3-5%) by increasing the spark ignition timing advance.
How it is installed
Plug and play, with no cutting or splicing. With the engine off for at least 10 minutes, unplug the accelerator pedal connector, plug our model-specific harness in between the pedal and the car's plug, then place the control box out of sight and mount the display where you can see it. Instructions are included.

Tell us your car when you order
Please message us your year, build date and model (and engine if you know it) when you order. We match the controller and model-specific harness to your car and confirm it before it is sent.

Tuning wire (optional)
The tuning wire adds more HP by increasing the spark ignition timing advance. It runs from the controller box into the engine bay and plugs into a model-specific harness (instructions included). The wire is made to order, so allow up to an extra week. Petrol engines only: diesel and electric vehicles have no spark ignition, so the tuning wire does not apply to them.
Features
Removes throttle lag; on turbo cars it reduces turbo lag
Eco, Standard, Sport and Sport+ modes, plus anti-abuse and immobiliser modes
