Made in the USA!  The Zeitronix Wideband Air/Fuel ratio meter and datalogging system is a high quality, stand-alone system for use with carbureted and electronic fuel injection engines. The new Zt-3 has the same high quality, high precision air fuel ratio readings as the Zeitronix signature Zt-2 wideband. The Zt-3 supports wideband air fuel ratio and lambda readings, adjustable simulated narrowband output and a new configurable linear wideband output for ease of use with engine management systems and 3rd party gauges. The new Zt-3's dimensions are only 3 by 2 by 1 inches. The case includes slots case for easy zip tie mounting in a tucked away location.

Works with a stand alone engine management system, a piggy back fuel control or a carbureted engine. Finally you can tune for more power, closer to the edge, precisely monitoring Air/Fuel ratio and datalogging up to 9 hours of data with a blazing rate of 70 samples per seconds per graph.

Very simple installation - connect two wires to +12V and ground and place the O2 sensor in the exhaust stream and you are ready to read AFR! A simple LED indicator displays off, warm-up and running modes.

Zeitronix Hacker/Tweaker AFR Display Board with Blue LEDs

This is for the serious enthusiast who wants to make their 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 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 AFR display. Like all LED displays it requires a tinted foil or Lexan cover (not included). There are two mounting holes for screws or standoffs. It powers up right from the Zt-2 or Zt-3 DATA port.
