EFI LIVE : ERROR CODE $2081Updated 2 years ago
This error code is common and it comes from time to time, it is a very fixable issue! Lets try the following.
(1) Check Point #1 ( Most Common Issue )
Is the ignition turned on to the "run" position? (ENGINE OFF/ACCESSORIES ON)
This error code appears when the keys are not set on the RUN/ON/ACCESSORIES ON position, this is because the EFI LIVE is not getting sufficient voltage to the device, when the ON POSITION is engaged, this error code should disappear.
First Check if it is in the ON/ACCESSORIES ON position, if it is not, go back to the EFI LIVE main settings, put your keys in the correct position, then navigate back to the tunes.
Once confirmed you are in the right position, attempt to install the tunes again. If the error persists, go to (2)
(2) Check Point #2 ( Takes trial and error)
You have confirmed the keys are on the ON/ACCESSORIES ON position but you are still getting an error message. If you have a 2018+ model, please ensure that your Bypass cable is connected correctly. Here is a link to assist you with the connection

Check if the connections are correct, then try to install the tune, if the error persists, go to the next step
Make sure the connections are firmly in place , then try to install the tune, if the error persists, go to the next step
Attempt to reverse the connections, sometimes the factory pins the wires to the incorrect location. Reverse the connection then try to install the tune, if the error persists, go to the next step
Try different slots nearby and try to install the tune again.
If the error still persists, please go to the next step.
(3) Check point #3
