narrow band can be used for reference - but better to run on the rich side of 14.5 afr than leaner. It is quite possible to tune to 14.5afr and than richen it up a little.
Although the curve is non-linear, we can see voltage variation between 12.5 to 14.5. I agreed, is not ideal.

Richard, of the three signals you mention I'd only fudge the AFM a bit (only at revs/loads where it runs open loop ofcourse!)
In fact I'm doing this on the supra, gaining an extra 5% power (at a minimum)
I'd avoid fudging the CTS signal because of the risk that the ECU decides to swap maps altogether. Not good.
