Forward & Reverse Speed Adjustment

Speed adjustment is the most common customer request. The KRAKEN gives you complete control over both forward and reverse speeds.

  • Use Increase/Decrease buttons to navigate to Forward Speed or Reverse Speed
  • Once the speed parameter is displayed, use Increase/Decrease to adjust in 0.5 MPH steps
  • Maximum: 25.5 MPH forward / 7 MPH reverse
  • Setting either to 0 MPH disables forward or reverse motion
  • Click "Flash" to save the speed setting
Speed Workflow: After flashing forward speed, reverse speed will automatically appear for adjustment. Set forward → Flash → Set reverse → Flash.
Forward speed set to 25.5 MPH
Forward speed adjusted to maximum 25.5 MPH
Reverse speed set to 7 MPH
Reverse speed adjusted to maximum 7 MPH
Actual Speed with Larger Wheels: The speeds shown (25.5 MPH forward / 7 MPH reverse) are based on stock wheel sizes. Carts with larger wheels will achieve actual speeds around 30 MPH depending on configuration.
6

Acceleration Selection

The RXV 2025+ offers four distinct acceleration profiles, allowing you to customize how quickly your cart responds to throttle input.

How to Adjust:
  1. Press the Parameter button until "Acceleration" appears on screen
  2. Press the Adjust button to cycle through the four levels
  3. Click "Flash" to save your selection

Acceleration Levels:

0 - GENTLE Gentle Acceleration

Smooth, gradual acceleration. Ideal for passengers or cautious driving.

1 - MEDIUM Medium Acceleration

Balanced acceleration. Good for everyday use and mixed terrain.

2 - FAST Fast Acceleration

Quick response. More spirited driving without being harsh.

3 - AGGRESSIVE Aggressive Acceleration

Maximum acceleration. Sports-car-like throttle response.

Customer Favorite: Most customers prefer Fast (2) or Aggressive (3) settings for the best performance experience. These settings provide the most dramatic improvement over factory programming.
7

Deceleration Selection

Deceleration control determines how aggressively the cart slows down when the customer releases the accelerator. The RXV 2025+ offers four deceleration profiles.

How to Adjust:
  1. Press the Parameter button until "Deceleration" appears on screen
  2. Press the Adjust button to cycle through the four levels
  3. Click "Flash" to save your selection

Deceleration Levels:

0 - COAST Coast Deceleration

Minimal braking. Cart coasts freely when throttle released.

1 - MILD Mild Deceleration

Light regenerative braking. Gentle slowdown with energy recovery.

2 - FIRM Firm Deceleration

Moderate braking. Noticeable slowdown with good energy recovery.

3 - STOUT Stout Deceleration

Strong braking. Aggressive slowdown with maximum energy recovery.

How It Works: Higher deceleration settings use regenerative braking to convert kinetic energy back into battery charge, extending range while providing a "one-pedal driving" feel similar to modern electric vehicles.
Pairing Recommendations: Match deceleration to acceleration for the best driving experience:
  • Gentle Accel + Coast/Mild Decel = Smooth, relaxed driving
  • Medium Accel + Mild/Firm Decel = Balanced everyday driving
  • Fast/Aggressive Accel + Firm/Stout Decel = Sporty, responsive driving
8

ECO Mode

ECO Mode is an energy conservation feature that optimizes the cart's performance for maximum range and efficiency.

How to Toggle: Click the ECO Mode button to view the current setting (ON or OFF), then click again to toggle. Click "Flash" to save your selection.
OFF ECO Mode OFF

Full performance mode - maximum power and acceleration

ON ECO Mode ON

Energy saving mode - extended range with reduced power

Range Extension: ECO Mode can extend range by 20-30% depending on terrain and driving style. Ideal for customers concerned about battery range or those primarily driving on flat terrain where full power isn't needed.
9

Reverse Buzzer Control

The reverse buzzer (backup beeper) can be enabled or disabled based on customer preference.

How to Toggle: Click the Buzzer button to view the current setting (ON or OFF), then click again to toggle. Click "Flash" to save your selection.
OFF Buzzer OFF

Silent reverse operation - no warning sound

ON Buzzer ON

Audible warning when reversing - safety alert

Popular Request: Many customers prefer to disable the buzzer for quiet operation in residential neighborhoods. This is one of the most commonly requested modifications.
Safety Reminder: When disabled, customers should exercise increased caution when reversing, especially in crowded areas or around children and pets.
10

Smart Regenerative Braking

Smart Regenerative Braking is an advanced feature exclusive to the RXV 2025+ that intelligently manages energy recovery.

How to Adjust:
  1. Press the Parameter button until "Smart Regen" appears on screen
  2. Press the Adjust button to toggle between OFF and ON
  3. Click "Flash" to save your selection
OFF Smart Regen OFF

Standard regenerative braking based on deceleration setting

ON Smart Regen ON

Intelligent energy recovery optimized for terrain and speed

Range Benefits: Smart Regen can increase range by an additional 5-10% beyond standard regenerative braking. On hilly terrain, benefits can reach 15-20%. Works in conjunction with the selected Deceleration level.
Best Practice: Most users keep Smart Regen enabled at all times for maximum efficiency. For maximum range, pair Smart Regen ON with Firm or Stout deceleration.
11

Power Information

This device is powered by the cart. No external batteries are required.

Always Powered: As long as the KRAKEN is connected to the cart via the Curtis connector, it draws power directly from the cart's system.

Finished Programming

Once you've completed your programming session and applied all desired changes:

  • Disconnect the cable from the cart's connector
  • Replace the protective cap on the connector
  • Store the KRAKEN Programmer in its protective case until next use
Best Practice: The device should only remain connected during active programming sessions. Disconnecting after use helps preserve the cart's battery and protects the device's electronics.
