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. With discount code SPEEDCODE4, the User version is just $325.

Speed Code Evolution

Whether you want to speed up a Club Car Precedent I2 Excel or speed up a Club Car Tempo, our programmer works with Curtis 1515 controllers (1515-5201, 1515-5206, 1515-5207). Unlike one-time dealer programming, you get unlimited adjustability for one low price.
