- | ====== Available ECU inputs ====== | ||
- | |||
- | Note that the following lists out all the available inputs on the 1G and 2G DSM ECUs. Most of these have special cases associated with them to be useful as a general purpose analog input. The most freely available inputs are the EGRTemp input on a 1G ECU and the RearO2 and MDP inputs on the 2G ECU. The rest have special cases to consider with them. Some may even require a [[ECUInputData|buffer circuit]] to be driven properly, depending on which sensors is connected to which input. | ||

- | ===== 1G ECU ===== | ||
- | |||
- | * EGR Temp Input (ECU Pin 15) | ||
- | * IAT Input (ECU Pin 8) - **Requires [[ignoreiatbaro|GM MAFT w/Ignore IAT/Baro]] selected.** | ||
- | * Baro Input (ECU Pin 16) - **Requires [[ignoreiatbaro|GM MAFT w/Ignore IAT/Baro]] selected.** | ||
- | * Front O2 (ECU Pin 4) - **Only usable when "Open Loop" option is selected (V2 or V3), or narrowband O@ simulation is enabled (V3 only).** | ||
- | |||
- | ===== 2G ECU ===== | ||
- | |||
- | * Rear O2 (ECU Pin 75) | ||
- | * MDP (ECU Pin 73) | ||
- | * Baro (ECU Pin 85) - **Requires [[ignoreiatbaro|GM MAFT w/Ignore IAT/Baro]] selected. Has internal pull down resistor making it unsuitable for certain sensors (see [[2gBaroInputWorkaround|work around]]).** | ||
- | * IAT (ECU Pin 72) - **Requires [[ignoreiatbaro|GM MAFT w/Ignore IAT/Baro]] selected.** | ||
