depo wind band meter gauge use BOSCH 4.9 windeband meter that provide analog output that can connected to standalone ECU

analog output wire harness instruction for depo windband gauge

black - engine ground ( gose to ground do I have to connect it to ECU ground?)

brown - wideband analog output 0-5v ( were I can connect this one ?)

green - narrow band meter 0-1v ( were I can connect this one ?)

motec m84 has

pin 25 - lambda 1 sensor input

pin 26- lambda 1 pump current (this one for what exactly )

how I connect my LSU 4.9 BOSCH sensor were I connect brown and green wires ?

Hi,

If the wideband meter is controlling the Lambda sensor then you only need to use the wideband output from the meter in to the M84, and let the meter control the sensor.

Using the brown (wideband analogue output) into pin B25 and setting up a custom lambda table in the Input Setup will get the signal into the M84. The black ground wire should go to a common ground with the M84. The green narrow band output is not used.
