Yo dlampe,
I've been looking into the same hardware changes.
I have a narrow-band O2 sensor/gauge combo that sort of works. I recently switched to a wide-band unit for my Holley EFI setup and am greatly pleased with the results. I'd like my gauge to be as accurate!
There are a few wide-band setups out there. Alas, they use their own "space-age" light bar gauge when all I'd like to do is hook up a wide-band O2 sensor's output to my present, more period correct analog gauge.
The problem is that that wide-band units must use a heater and therefore a different harness, and that their output is approx linear 0-5V where the narrow band units are extremely nonlinear and produce more like 0-1V output.
I've e-mailed several places, including the gauge mfr, but so far, no joy. The gauge guy said "we can do that" but then never got back to me.
I'll let you know if I'm successful - and would appreciate it if you'd do the same.
Regards,
Tom
