Lambda OutVEMS Wideband & EGT gauge can simulate the behaviour of a standard Oxygen sensor, and is configurable as either Narrow or Wide band sensor's output. This is not intended to be a 'drop-in' replacement for an OEM sensor, but can be used by some 3rd party ECU and Datalogging systems. Ask your dealer for specific information.
Narrow Band OutputFor many OEM systems it will be possible to use the gauge's LSM11 simulated output.
Wideband OutputThe gauge can be configured to output the lambda reading across a range of voltages to allow most aftermarket ECUs to use Wideband feedback. We recommend three possible outputs: 1V/Lambda, 2V/Lambda, or 3V/Lambda.
So if you select 1V/Lambda the voltage from the Multifunction Plug's Pin-1 will be: 0.8V at lambda0.8, 1.0V at Lambda1.
If you select 3V/Lambda then Lambda0.8 will give 2.4V and Lambda1 3.0v
Configuring Lambda OutputIn MegaTune goto the Menu option Settings->Inputs and Outputs, and you will be presented with the following screen:
To set the output we use the Analog output settings box:
* Narrow band - Enter 1
* Wideband 1V/Lambda - Enter 51
* Wideband 2V/Lambda - Enter 102
* Wideband 3V/Lambda (Motec default) - Enter 153
