JoeNova I sent you a pm on corvette forum hopefully that is allowed haha. Arduino boot controller was one of the projects I thought about. I want to try and do a successful project with failsafes then move on to new projects.

I know it's an old thread, but thanks for this BADASS idea. I'm going to get one of those AEM failsafe gauges or something similar and wire it in. Definitely gonna go the timing cut route. I'd say pulling 10* of timing is enough to get attention, and it's instantaneous. I like the iat idea, but if the reason you're leaning is because of a failing pump or injector, then it doesn't matter what the computer tries.
I've been trying to figure out a way to do it based on fuel pressure in the past, but a gauge that can send a signal under predetermined boost & AFR conditions is a life-saver given enough time. My best guess is any positive manifold pressure with an AFR over around 12.2. I guess the only thing that pops into mind is that I see lean spikes between power shifts that I have so far been unable to tune away. If the system is fast enough, then it won't matter.
