The 'IO Setup' tab (when using a Default Layout) in MEITE allows your to configure the various outputs of the ECU, as well as perform test functions on the ECUs outputs, and to test wiring and systems on the engine.

The tab consists of Output Settings, Digital Input Settings, Analog Input Settings and Tachometer Settings.


For the plug-and-play range of ECUs, the I/O is very much defined by the circuit board itself, so you should normally just load a basemap for the PnP system, and leave the I/O settings alone. For wire-in ECUs, you can use the I/O settings to assign different functions to the spare inputs and outputs, as well as repurpose things such as unused injector channels.


Below you can see a typical I/O Setup for an ME442 Plug-In ECU. We can see that the user has decided to control a Boost solenoid on LS 10 output, and the Primary Fan on Relay LS 12. 



You should wire your engine as per the I/O settings, or change the I/O settings to suit your wiring - more information on physical connectivity is given in the hardware install guides for the PnP Range, as well as the ME221 Wire-In install guide - all available from the ME website.


You can also see how the Analogue sensor inputs have been chosen and routed, under the ADC settings. These should typically be left as such, but, for example, if you wanted to swap the Inlet Air temp and coolant temp wiring, you could swap the settings in this dialogue to reflect that change. Always be sure to point sensors to a "RAW" input where possible. These RAW values are then passed to the HRT of that sensor, which then converts it to the correct unit and value.
