Anyone figure out where to put this yet? I was under the car and I'm thinking in the y-pipe is about the only accessable place to put it. I know it's after the pre-cats, but hey if dyno's are using sniffers in the tailpipes this can't be all bad.
Also, outside of tripping a CEL what's wrong with just unscrewing an O2 sensor and screwing this unit in to get the A/F ratio?
