great idea! Along the same lines, a carefully selected overtemp switch(snap switch, whichever you want to call it) could also be used as a failsafe, or as the trigger to switch back to normal, closed loop O2 signal. I believe they come as normally open OR normally closed switches....
I only mention this because I'm a cheap b?st?rd and might have access to something like that cheap.... And, for my case, I don't want to go too lean, just want to get back to a normal-ish O2 signal with any mod I install....
I would imagine an EGT would be a better feedback device, letting you see what temp your at along the way.....
