OIL/COOLANT TEMP AND AIR/FUEL RATIO GAUGES INSTALLED
The gauges are installed. I went ahead and had the wideband sensor installed in addition to the factory narrowband sensor, underscore. They welded the bung for the wideband sensor down low, which doesn't surprise. I'm not entirely sure what effect that might have on the reading. Probably minor.
The overall cost to get it all wired in was $588.50. It was a bit more than I wanted it to cost but they were quick about it and it's set up clean both in the cockpit and engine compartment. Overall project cost: $1258.30. I can see why so many owners get real handy with their cars. That's about it for a while, now.
The AutoMeter dual temp gauge operation was a little opaque at first. I had to squint and really read the instructions. But basically, you can display both channels at the same time.
Oil temp is channel one, measured from the access point that the oil pressure switch is located at. This is displayed in numbers at the center of the gauge, and the range is 100 to 340F. Coolant temp (measured at the hose leading to the engine block returning from the radiator) is channel two, and the range is currently set to 100 to 260 degrees Fahrenheit via the 30 LEDs. 0 LEDs is 100F or lower. 1 LED is 105F, then each LED after is 5 degrees. 15 LEDs is 175F, 30 LEDs is 260F--I expect never to get to 260F on coolant return! I can set an alarm, to warn me of excessive temperatures.
I can set it to a variety of ranges:
60 to 210F
100 to 260F
140 to 280F
100 to 240F
40 to 120C
60 to 140C
60 to 170C
The air-fuel ratio gauge is pretty straightforward--bar gauge around the outside for gross indicator rich to lean, and the digital reading in the center.
This picture was taken before I set the channels and how they display. They were used to AEM equipment, so the AutoMeter logic threw them a little.
On the drive back home, I noticed it liked to hang out right at 14.8. I got wide open throttle and observed as low as 12.5:1 at 5000rpm and 8psi, which is not too far off the fuel table you showed me grip-addict. Your fuel map was showing 11.5:1 at the same performance band.
I just took it out on another test drive, to check the function of the gauges. Reviewing the video now...
10.8:1 air:fuel at 5600rpm and stock max psi boost, so in the neighborhood of 10 psi. That is slightly too rich, I believe, but in the neighborhood of your fuel table grip-addict.
Highest it got on the coolant temp at the return was 200F, and that as it was heat soaking at the cooldown lap. Highest it got on the oil temp was 195F, again, during the cooldown lap.
Very pleased in general.
