| - | ====== MFI Schematic - I/O ====== | ||
| - | This page is a collection of notes on how to read certain information off the MFI schematic in the DSM shop manual. First, reference the [[http://www.dsmlink.com/images/forums/2GECUMFI.pdf|2G MFI schematic]] (or the [[http://www.dsmlink.com/images/forums/1GECUMFI.pdf|1G MFI schematic]]) for an example of what this schematic looks like. | ||

| - | ==== Input - analog ==== | ||
| - | {{http://www.ecmtuning.com/images/forums/ecudocs/input-analog.gif }} | ||
| - | |||
| - | This is a simple analog (0-5v) input to the ECU. No significant load on the sensor is illustrated in this diagram. | ||

| - | ==== Input - analog w/pull down ==== | ||
| - | {{http://www.ecmtuning.com/images/forums/ecudocs/input-analog-pulldown.gif }} | ||
| - | This is a 0-5v input to the ECU but with a pull down through some resistor. The implication here is that any voltage source (sensor) connected to this input will be expected to drive the load of that pull down. Some sensors simply can not do this. You can get more info on our [[ecuinputdata|ECU Input Data]] page. | ||

| - | ==== Input - analog w/pull up & down ==== | ||
