I already have the /6 dash guagues but not the center console guages (voltmeter & oil temp).
I am not totally sure my oil pressure guague works properly, but I digress... What I want to know is, would it be be advantageous to have all these guagues (and working of course)? What are the most important secondary guagues (not Spedo & Tach) for these cars? |

The LM3914 is also found in nearly every narrow-band A/F meter on the market. There are schematics for a several such meters available online. You'd need an op-amp to boost the weak thermocouple signal from 10s of mV to at least 1v, but that's also pretty cheap.
The thing I have in mind is a low-end microcontroller driving an LCD display. An 8x2 character display will fit on the lower third of the tach face, and this would give enough room for four CHTs, or two CHTs and two EGTs, or several other things. Still under $50 in parts costs. |
