Re: O2 sensor in SPICA car

[Ian Lomax <sfalfisto@domain.elided>]

Hey Tim,

When I added one to mine, a custom exhaust shop found
room to put it just in front of the resonator.  That
way it reads all four cylinders, and isn't too far
away.  A one wire sensor might be too cold behind the
resonator, espcially at idle.

If you need them, I'll see if I can borrow a digital
camera and snap a photo.

Ciao,
