IAT Sensor Mod Experiment

[rockouthippie]

This isn't gonna work for most cars. If you have a O2 sensor, the computer probably will override your new mixture settings. This sounds a lot like an oxygen sensor mod I did on a Eagle Talon. It would go like raped batsh*t, but running that rich screwed up the cat converter. It got 12mpg city, but I didn't care.

That's the whole point of this system. To keep the cat converter from getting unburned gas through it. Clogs em up tighter than a drum. 2 cat converters in 3 years taught me the error of my ways.

I think if I was gonna try this, I'd make sure it had a switch for overriding it most of the time. This would give you control over your fuel mixture, if the O2 sensor doesn't override your trickery.

So, if I figure this right, you could either rich the engine out or lean it out with this trick. Being too lean will burn valves. Being too rich will clog the cat converter up. Neither is going to pass DEQ.

If you guys want to really beef up your fuel injected stock rods, you should use a bigger throttle body. It's pretty much "bolt on" 25 hp. I got an aftermarket one for my Lincoln for $200.
