This is a crazy tiny wideband oxygen sensor controller. Designed to be used with the Bosch LSU 4.9 sensor. It can be retrofitted inside your ECU case or almost anywhere since it’s so tiny. Keep in mind that to keep this guy tiny he needs an external 5V power supply. This can be taken from the ECU or other source.
What you see is what you get. This is the module only, no wires, pins or sensor included.
Do NOT cut the connector end from the sensor it contains an important calibration resistor.
This is an original, authentic, and authorized product of DIY-EFI.
