NEW Zeitronix Hacker/Tweaker
AFR/Lambda Display Board


Hacker/Tweaker AFR/Lambda Display Board

This is for you, the hard core Hacker/Tweaker who wants to make your car stand out from the crowd with a super stealth and clean in-dash installation. So file, grind and glue until you have a clean, integrated, in-dash wideband AFR display.
The Zeitronix Hacker/Tweaker is a very small AFR or Lambda display for the Zt-2 or Zt-3 Wideband Systems. Designed to fit into tight spots, full board dimensions are less than 2" by 1". The minimum opening to display the digital readout is only 0.56 x 1.4 inches. It's an open frame and bare board display meant to be mounted in the dash, in place of a stock clock or wherever you, the Hacker/Tweaker wants to mount a discrete wideband display. Like all LED displays it requires a tinted foil or Lexan cover. There are two mounting holes for screws or standoffs. It powers up right from the Zt-2 or Zt-3 DATA port.
This is an open frame unit. Handle with care and keep ESD precautions.

The Hacker/Tweaker is available in units of AFR or Lambda and blue or red digit colors.

See our gallery (and below) for some inspiring display installation pictures.
