Beyond Traditional Speed Code 4

When searching for "club car speed code 4 unlock" or "club car speed code unlock", you'll find the standard 19.6 MPH upgrade. Our advanced programmer goes further - delivering 20 MPH (what some refer to as "Speed Code 5") plus on-demand adjustability that saves you hundreds over dealer visits.

The Real Cost of Speed Programming

Dealers use tools like the Curtis 1313 handheld programmer to unlock speed codes, charging $200-500 per session. Want to change settings later? That's another appointment and fee. Need to check a fault code? More money. Our device puts that same capability - and more - in your hands permanently.

Speed Code Evolution

Whether you want to "speed up Club Car Precedent" or "speed up Club Car Tempo", our programmer works with all Curtis controllers including the 1510, 1510A, and 1515 models. Unlike one-time dealer programming, you get unlimited adjustability.

Why On-Demand Control Matters

Frequently Asked Questions

Can I change speeds whenever I want?
Yes! Unlike going to a dealer where you pay $200-500 for each speed change, our programmer gives you unlimited on-demand adjustments. Switch between 14.8 MPH for a new driver and 20 MPH for yourself as many times as you want. No appointments, no additional fees - just instant control whenever you need it.
What's the difference between Speed Code 4 and your 20 MPH unlock?
Traditional Speed Code 4 caps at 19.6 MPH - that's what dealers program using tools like the Curtis 1313. Our advanced programmer pushes to 20 MPH (sometimes called "Speed Code 5" by others) and adds diagnostic features like fault code reading, acceleration tuning, walkaway mode, and more. Plus, you can make unlimited changes without dealer visits.
What's the difference between User and Dealer versions?
User Version: One-time use programmer that pairs to your specific cart. Includes all features - 20 MPH speed, diagnostics, and tuning options. Perfect for personal use.

Dealer Version: Unlimited use on multiple carts. Ideal for golf cart dealers, rental fleets, or anyone with multiple carts.
Can I see what's wrong with my cart?
Yes! Our programmer includes fault diagnostic capabilities. View any active error codes in your Curtis controller instantly. Dealers typically charge $100+ just to check codes - now you can do it yourself anytime. This feature alone can save hundreds in diagnostic fees.
Will this work with my Curtis 1515 controller?
Absolutely! Works with all Curtis controllers including Curtis 1515 (Tempo), Curtis 1510A, and Curtis 1510 (Precedent). Full compatibility with 48V systems from 2004 to current models.
What tuning features can I adjust?
Customize: Acceleration profiles (smooth vs aggressive), Walkaway mode (auto-brake when exiting), Pedal up speed (coasting behavior), and Excel braking (regenerative braking strength). These let you tune your cart exactly to your preferences.
How does this compare to a Curtis 1313 programmer?
The Curtis 1313 is what dealers use - it's a professional tool that costs $500+ and can program speed codes and settings. Our device provides similar capabilities plus 20 MPH speed (beyond the 19.6 MPH Speed Code 4), and is designed for cart owners rather than dealers. The key difference: you own it and can make unlimited changes without paying for each adjustment.
Is 20 MPH safe for my Club Car?
Yes, when properly programmed. Our 20 MPH setting works within safe operating parameters of your Curtis controller and motor. The cart was engineered to handle these speeds - manufacturers simply limit them for liability reasons. Always follow local laws regarding golf cart speeds on public roads.
