You could always stick a resistor on your o2 sensor feed wire that would trick it to running super lean.

resistor would essentially "hide" some of the voltage that the o2 would be pumping out, thus the computer wouldn't read it's typical .45 volts, would read .1 instead - thus tricking it to thinking that the o2 sensor is reporting the lean condition and then taking itself out of the closed loop operation or going to a default "save my own ***" fuel load.
I'm unsure if that can be worked out in combo with the coolant sensor trick.
Trick computer that you're running lean to compensate for your ghettro setup, that's what I was getting at.

well, it's all good, i'll just do the coolant temp sensor for tonight so i can hit 5 ish. i talked to the man about my ecu today and he over nighted it today to make up for his slackness, he only lives 6 hours away, so it will definitely be here tomorrow. sorry to dissappoint you guys, but no mo ghetto

Re:how dangerous is this???
oh, and the only way to properly find out what's going on in your engine would be to do a high rev shut off.. ya see when you're driving around town and you hit boost and your motor gets that nice 17:1 a.f.r. then you idle it for a while your plugs are "somewhat" turning back to normal.
so you really don't have the exact figure of what's going on since you're pulling the plugs after you get home, after they've been washed clean a little bit.
this is from the old school of hotrodding when our motors got 8mpg and we didn't have fancy electronic gadjets like o2 meters and where we also were able to brew our own meth in our OWN bathtubs, not no mexican meth factory.. well j/k about the meth part.

Re:how dangerous is this???
well, i did the 'coolant temp sensor trick', it definitely runs rich, idles like ---- though just like a cold morning start at about 1800 :P but i took her up to 6 psi and the a/f gauge was full rich and heard no detonation. my ------- map sensor cel doesn't even come on any more
