That gauge is a wideband and boost guage all rolled into one, and includes a "failsafe" to protect against engine damage, and a small datalogger all in one...

just monitors AFR and can trigger user defined tables if it senses out of range AFR.. The failsafe junk may only work when using AEM EMS's, not sure.
