Zeitronix Wideband EGO Controller

If you're serious about tuning your own car, then you need something far more accurate than the standard Narrowband (NB) Lambda sensors. NB sensors only operate within a small range and are really only accurate around stoichiometric (Lambda 1.00), which is where a Wideband (WB) Lambda sensor and controller comes in. There are many different options available when it comes to choosing a WB Controller, that it can become confusing. We highly recommend the Zeitronix Zt-2 Kit due to it's affordable price and amazing functionality - it's the one we use to tune our customers' cars. The controller itself is a compact box that can be attached anywhere, like on top of the ECU, being the size of a 1" thick business card. The Zt-2 is not just a WB Controller though and for those without standalone ECUs it's functionality is a powerful tool. Not only does it log Lambda and AFR through the Windows software, there are a number of inputs that can aid tuning such as RPM, Throttle Position, Manifold Pressure, Exhaust Gas Temperature and a User Defined Input. All of these functions can be displayed as numbers or graphed and saved for future analysis.
