Take control of your throttle response with the Z1 Throttle Pro, a throttle controller and pedal controller designed for the Nissan 350Z and Infiniti G35. Adjust how quickly your car responds to pedal input and customize the throttle feel to match your driving style, from smooth and relaxed to sharp and immediate.

Now, let’s clear this up right away: the Throttle Pro doesn’t add horsepower. It won’t turn your VQ into a twin-turbo monster. What it does is let you customize how your existing power feels and responds, transforming the driving experience without touching a single bolt under the hood.

Customizable Pedal Response

The Throttle Pro gives you full control over your car’s throttle mapping. Through the dedicated mobile app, you can quickly switch between three built-in modes:

Eco – Smooths out response for easier throttle control.
Stock – Restores the factory mapping, no changes.
Sport – Sharpens pedal feel for a more direct, performance-oriented response.
If that’s not enough, you can create custom presets of your own. Adjust throttle sensitivity at five input points (20%, 40%, 60%, 80%, 100%) to craft the exact feel you want, whether it’s ultra-linear or instant-on.

Seamless Power, Total Control

The Throttle Pro gets installed in line with your factory accelerator pedal, taking control of and modifying the signal that is sent to the ECU. Power is supplied via the OBD2 port for a more reliable 12V supply, without putting additional stress on the factory 5V pedal power supply. The plug even includes a pass-through connector, so you can keep other devices like ECUTEK dongles or insurance trackers connected at the same time.

All presets are stored internally, so if power is lost, the Throttle Pro automatically returns to the same mode once it’s restored — no need to reconnect or reprogram. It’s built to integrate seamlessly into your setup, whether you’re running a completely stock ECU or a full custom tune.

For tuned cars, the Throttle Pro adds another layer of adjustability, letting you make fine changes to throttle behavior without reflashing the ECU. Dial in quicker response for spirited driving, or tone it down for smoother throttle control in traffic. The choice is yours.
