Default AEM Water/Meth Failsafe (how to trigger limp mode)

Good day,

I am currently using water/meth for safety only but am considering using it more aggressively. I have been researching the AEM failsafe kit.. looks pretty impressive.

I would like to know if anyone out there is using this kit to trigger "limp mode" in the stock ECU.

My specific questions (2005 STi) are:

* How do you trigger "limp mode" with the AEM kit?

* When you trigger "limp mode" can you confirm what happens in the ECU.. My guess is:

When limp mode is triggered...

The fail safe fuel maps are activated.

The boost target KCA additive low map would be activated.

The timing advance multiplier would go to zero.

Thanks for the feedback
