Zeitronix ZT-2 Wideband with display, including boost sensor. Add an EGT sensor for maximum usage. Displays Lambda, AFR, boost/vac and EGT. Logs via serial cable and software downloaded from the Zeitronix website.
Phil sold his a while back, but I am probably selling mine. I need it for the rest of the season (until october 29th), and then you guys can have it. I have the entire package, zeitronix display, low mileage wideband sensor, boost sensor (used for 3k miles), and EGT gauge.
