This is the Curtis 1268 500-amp speed controller built for 2001-Up E-Z-GO TXT carts running the PDS (Precision Drive System) drivetrain. It is a meaningful step up from the factory controller — more amps means stronger off-the-line torque and smoother high-load behavior on hills, in sand, and with a loaded cart. If your TXT PDS feels lazy, surges, or has thrown a controller fault that will not clear, this is the upgrade path most cart owners eventually take.
Compatibility
- E-Z-GO TXT Electric, PDS drivetrain only (does NOT fit DCS or ITS — verify before ordering)
- Model years 2000 through 2009
- ITS-throttle input (uses the factory PDS throttle sensor)
- Footprint: 9" × 7" × 3" — matches the original 1268 controller mounting pattern
Features & specs
- Genuine Curtis 1268 controller, 500-amp continuous rating
- ITS throttle input — direct plug to the PDS pedal sensor
- Smoother torque ramp than the factory unit — measurable difference in low-speed creep and hill starts
- Fault diagnostics over the Curtis programming port — easy to read with a 1313 handheld or laptop programmer
- Sealed enclosure suitable for cart-bay humidity and dust
Installation & programming notes
This controller is plug-compatible with the OEM 1268 footprint on PDS TXTs — same B+/B-/M-/A2 lug layout, same low-voltage harness. The catch is programming. PDS carts need the throttle range relearned and the current limit set to match your battery pack (lead-acid vs lithium changes the right setting). Skip that step and you will get hesitation off the pedal and an under-current Curtis code. We recommend running a Curtis 1313 handheld programmer or having a tech with one do the initial setup; cross-reference the wire colors in our EZGO schematics library.
What it pairs with
If you are building a full TXT PDS performance upgrade, the typical bundle is this controller + a heavy-duty solenoid + new battery cables sized to the higher current. Match this with the Curtis 48V heavy-duty solenoid and a 48V lithium pack for a complete drivetrain refresh.
