Description
The AMP EFI Wideband is a high-accuracy, Bosch-powered air/fuel ratio monitoring system designed for precision tuning and rock-solid reliability. Featuring a genuine Bosch controller chip and LSU 4.9 sensor, this package ensures stable AFR readings, and with Bosch’s heater control strategy (and proper user installation), we can ensure long, OEM-like sensor lifespan. With both fully isolated analog and CANBus connection options, it’s versatile enough for any installation. Proudly Made in the USA and housed in a rugged, weatherproof metal enclosure for under-hood or in-cabin use.
Key Features
-
Bosch LSU 4.9 Sensor & IC Chip – Get OE level, industry-leading accuracy and response time, proper sensor warmup strategy, and diagnostic fault code capability.
-
Onboard CANbus – CANbus message broadcast for elimination of errors with simple selectable addressing, allows for 1 or multiple widebands on the bus, compatible with MS3 and other ECUs and Dataloggers. Keep your valuable analog inputs free!
- 0-5v Analog Output – Isolated analog output with dedicated sensor ground eliminates ground offsets and errors when using analog connection to your ECU or Datalogger. Great for use with plug and play ECUs to eliminate ground offsets that would normally cause inaccurate readings
-
Rugged, Weatherproof Metal Enclosure – Suitable for under-hood or in-cabin installation
-
Analog Output with Dedicated Sensor Ground – Eliminates voltage offset issues and erratic readings
-
Fast, Stable AFR Data – Perfect for tuning and performance monitoring
- Made in the USA – Designed and manufactured in Gainesville, GA, USA!
