This Board Enables an Adaptronic Modular ECU (except the M1200) to control a single LSU 4.9 sensor directly by wiring the supplied harness into the ECU connectors. If you need to control more than one LSU 4.9 sensor you may add more wideband O2 modules into your Adaptronic Modular ECU provided that there are more small expansion ports available.
1. To install the board into the ECU you will first need to unplug the ECU from the vehicle and open the ECU up to have access to the small expansion slots. Opening the ECU up basically involves removing the onboard MAP sensor nuts. Using a flat head screw driver gently release the plastic tabs on the end-plate to release it. Then slide the vehicle board out of the plastic enclosure.
2. locate an available small module expansion slot and carefully insert the on-board wideband o2 controller module. The module has to be inserted in a specific way so that it lines up with the white outline printed on the main board. It also doesnt matter which small expansion port you choose as the ECU will automatically detect and tell the tuning software which pins on the ECU connector you are supposed to wire to. Which can be visually seen via the wiring guide under the HOME tab in Eugene.
3. Once the Module is set in place slide the main ECU board back into the enclosure and carefully reseal the ecu suing the end-plate and on-board MAP sensor nuts. Adaptronic recommends that once the ecu is back together to upgrade the ECU's firmware to ensure all modules are the same. The instructions for this are located under the FAQ section on this website.
4. After updating the firmware verify if the ECU detects the new module by going to the tuning software's ECU hardware settings menu then click on "Modules". There should be at least one small module address that shows "Lambda Module is connected.
5. With the ECU still connected access the tuning software's pinout page - Home - Wiring guide (or click F8) - and locate the 6 pins required for the sensor harness connection:
1. Pump cell negative - red wire
2. Pump cell positive - yellow wire
3. Heater negative - white wire
4. Heater positive - grey wire
5. Calibration resistor - green wire
6. Reference cell - black wire
If you are using an M2000 or M6000 ECU you can just insert the pins on the harness provided into the AMP superseal connectors. If you are using a Plug N Play ECU you will have to cut the superseal pins and replace them with the OEM ECU pins. (Tuned By Shawn can source/crimp them on for you)
6. After wiring up the sensor harness you may now connect the provided LSU 4.9 sensor and proceed with the softeare settings required. Note that the wideband 02 sensor is generally recommend to be installed about 23.5" away from the exhaust collector or turbocharger.
7. In the tuning software, go to inputs tab - O2 / Lambda sensors - O2 sensor 1 and set the connection type to "Internal Lambda" - now you are ready to tune!
Note there is no free-air calibration required because the internal calibration resistor is used for reference.
