Eliminate throttle lag in your RAM Promaster 2500 with the Pedal Commander. This guide diagnoses the issue and shows how the controller restores responsive acceleration.
Quick Answer
If your RAM Promaster 2500 feels sluggish off the line, the Pedal Commander eliminates the factory throttle delay by remapping the pedal signal, giving you instant, adjustable response.
Why the Promaster 2500 Feels Sluggish
The RAM Promaster 2500 (3rd Gen, 2014+) uses an electronic throttle that introduces a deliberate lag for smoother starts. While this helps in low-traction situations, it can make the van feel unresponsive when you need quick acceleration, like merging onto a highway or pulling away from a stop sign.
Trade-Off: Aggressive vs. Smooth
The Pedal Commander offers 5 driving modes (Eco, City, Sport, Sport+, and Race). Higher modes sharpen response but can make the pedal feel touchy in stop-and-go traffic. Most drivers find Sport mode a good balance for daily driving, while Race mode is best for passing or heavy loads.
Diagnosis: Fixing Throttle Lag in Your Promaster 2500
- Symptom: Pressing the accelerator pedal feels delayed; the van hesitates before accelerating, especially from a stop or at low speeds.
- Likely Cause: Factory electronic throttle mapping intentionally softens the initial pedal input to prevent jerky starts, creating a noticeable lag.
- Corrective Action: Install the Pedal Commander for RAM Promaster 2500 (product ID: 2707091). The device plugs inline with the pedal sensor and lets you select a mode that reduces or eliminates the delay. Start with Sport mode and adjust up or down based on feel. Test each mode in a safe area before relying on it in traffic.
- When to Stop or Choose Another Option: If you prefer the stock soft pedal feel for smooth starts (e.g., in snow or on gravel), the Pedal Commander may not be right for you. The device can be set to Eco mode for a softer response, but its primary purpose is to sharpen throttle, not soften it further.
