That's exactly the solution that Sean Meldrum was using for his
CKC (Curiosity Killed the Cat) module. A simple voltage divider
circuit consisting of two resistors which reduces the downstream
voltage output to about a tenth of the original value.
I'm basing my module on Sean's, but I don't want to retain the
downstream O2 sensor because I'm going to 3" pipe, and I don't feel
like paying someone to weld in a bung. Also, this version is a
lot more fun. :-)
