Holley Wideband 02 Controller

Want the ability to closely monitor Air/Fuel ratios on your carbureted or EFI vehicle? Wideband O2 sensors do not suffer as great a loss of data accuracy due to voltage and ground fluctuations. This is due in part to their spreading their range of accuracy over 5 volts typically, from 10:1 to 18:1. A wide band oxygen sensor is the ultimate addition to any carbureted or EFI vehicle. This kit will accurately measure any air/fuel ratio between 10:1 and 18:1 allowing the user to read the air/fuel ratio in real time for extremely accurate tuning. The (P/N 534-201) kit is intended for the individual who wants to be able to precisely measure air/fuel ratios to obtain the perfect tune. The (P/N 534-201) comes standard with Bosch LSU4 sensor, but offers the flexibility to be upgraded later for use with an NTK sensor by simply reconnecting a jumper loop and purchasing the NTK sensor (P/N 534-194). The Holley Wide Band O2 gauge included in the kit features a 3-digit numeric display along with a 40 segment bar graph. With the ultra-high intensity light emitting diodes you will be able to see your Air/Fuel ratio even under direct sunlight. The (P/N 534-201) is designed to operate in toughest street or race environments and will withstand heat, dirt, and vibration. The Holley Wide Band O2 gauge will fit in a standard 2-1/16" gauge pod.
