Check for a tune update

Jace checks your TDN and VIN against the current calibration for your machine. You get an email within one business day — and if there's a newer tune, it tells you how it gets to you. No charge to ask.

Altitude changes how your tune fuels. Type the dunes, trail area or town you ride most and pick it from the list.

    elevation

    For reference: Glamis sits around 300 ft, Sand Hollow around 3,000 ft and Little Sahara around 5,000 ft.

    We answer every request by email. If there's an update, the email says how it gets to you — through your flashing device or by sending the ECU in.
