AEM Universal Wideband Failsafe Gauge. Measures AFR and boost and allows programming for a failsafe condition. This means you can have it trigger an alarm or ECU mode (if equipped with standalone or EcuTek RaceROM) to reduce power and prevent engine damage. Has an auxiliary analog output to use with the AEM EMS or RaceROM custom map. We use this on the BRZ to feed the rear o2 sensor a real wideband output that can be used internally by the ECU.
