Failsafe strategy?
Anyone running an AEM boost/AFR failsafe gauge? What is your strategy? I've heard about connecting the output to a relay/resistor to the IAT to trigger an obscure cell, like -40* IAT to pull 10-15* of timing.
Has anyone done this? What about a different strategy? I was thinking using a relay to completely cut power to the injectors or even the ECM would be the safest. Am I overthinking this?
Thanks!

Thanks c5mtl! One more question if you don't mind. Where is your threshold for AFR? At what point do you have it trigger into failsafe under boost? Or is it varied by boost level?

need to look again but If I remember it starts monitoring at 12psi and triggers the safety leaner than 11.5...
