Hold down the two right hand buttons for 5 seconds then push the ON button once, This will do a hard reset on the unit. If the unit still doesn’t turn on, plug the unit into a power supply and repeat the process.

NOTE: a 65W power supply will work best.

To use an LCU1S with a MyChron 5 you will need different firmware to make this work.
Click here to download Firmware 01.32.38

You will need to download this to your computer then upload it to Race Studio 3. This will not be on RS3 without uploading the file.
NOTE: This firmware is for Mychron 5 Only NOT for MyChron 5S

To get a MyChron 6 1T to show either CHT or EGT as well as Lambda, you need to configure the unit to do so.
Go to System Settings > Temperature Setup and change the mode to Manual and then select the Temperature for the type of sensor you are plugging in - exhaust temp, head temp etc.

NOTE: This does not need to be done for water temp as the MyChron comes pre-programmed to show both water temp and Lambda.

Make sure the RPM cable is not wrapping around any of the temperature cables or LCU unit. The interference from the RPM cable can cause issues with the sensors, and may give a reading that is misleading.

To get your MyChron to show Lambda you need to configure a custom screen. Go to System Settings > Display Setup, then on the Page tab, press OK until you get to Custom 1. Go down and select Enable.

Once enabled, press the top left menu button to configure the custom screen. You can now select what data you want where, including Lambda. When finished you can then press the View button on the bottom right 4 times to take you back the main dash. Pushing the View button one more time will take you to your Custom Screen showing a small 1 in the top left and the Lambda value, or how ever you have configured that screen.

If your LCU1S stops working there are a few things you can check:

• Check that your MyChron has the latest firmware installed. Please see above for the latest Firmware information. Reinstalling the same Firmware over the top when the LCU1S is connected to the unit can sometimes rectify an issue.
• Make sure there is a secure connection to the terminals on your battery.
• Make sure the RPM cable is clear of the LCU1S, as the interference from the RPM cable can cause problems with the connection.

If you have tried everything above and it is still not giving you a reading, or the reading doesn’t move while the kart is running, it will most likely be a faulty sensor. When purchasing a new sensor, make sure you buy a genuine Bosch product. If the sensor is etched with 'Germany' and no 'BOSCH' wording it is not genuine. They will work initially, however they have a very short lifespan and will fail quickly. All sensors sold by DPE are genuine Bosch sensors.
