Zeitronix Wideband Systems can be paired together for dual channel operation. In dual channel configurations each wideband oxygen sensor connects to either a Zt-2 or Zt-3 wideband controller. Choose between two (2) Zt-2s, two (2) Zt-3s, or one (1) Zt-2 and one (1) Zt-3. Compare the Zt-2 and Zt-3 for the dual-AFR setup which will best meet your needs.

Several common left/right bank AFR setups are described below. Setups include single or multiple displays, real time software display and datalogging to the Black Box Data Logger.

Two Zeitronix wideband controllers together are considerably smaller than most other dual-AFR wideband solutions. A pair of Zeitronix wideband controllers can be zip-tied out of the way with minimal space required for a clean, simple dual air/fuel ratio installation.Left and right bank AFR display can be accomplished using a single ZR-2 Multi Gauge or LCD display. Other options include using multiple gauges, Zeitronix Data Logger software, DashDAQ display, ZR-1 AFR/Lambda display, Hacker/Tweaker display, and the Black Box Data Logger.
