Project Unfair won’t be using standard gauges. Instead, we are going to use the integrated dash display from Stack Systems. The Stack display has several advantages over traditional gauges:
- It allows the dash to be completely visible through the steering wheel. No more disco head-bob to see the gauges hidden behind the wheel.
- It’s programmable so that limits for each supported sensor can have alarms defined. Things like low oil pressure and too hot water temperature can turn on a light and then show the value of the sensor. When you’re on the track, you don’t have time to scan all your gauges to look for problems.
- It allows fine-tuning of your fuel tank sensor, so you’ll know within the gallon of how much fuel is left in the tank.
- It integrates with a data recorder so that data can be played back and analyzed later, along with data directly recorded such as sensor data for ride height, steering angle, and brake line pressure.
- The data recorder will be integrated with the Holley Dominator ECU allowing analysis of nearly all the available sensors in the car at the same time using the amazing DataPro Analysis system. No more coming in after a few hot laps with some sort of vague driver “It felt a little weird” or “the car was turning in slowly”. With DataPro, we’ll be able to tell exactly how the car responds to changes in tuning, be it suspension, braking, or engine.
- The wiring is dead simple. A single 19 circuit mil-spec connector provides all the connection needed.
Check out all the available real estate on the dash when it’s all integrated into a single display. The gauges on the lower right are boost and lambda gauges. We’ll integrate their sensors into the data recorder as well, though the dash display doesn’t have direct support for them. We’ll put A/C vents in the space to the left and right of the display, and the traditional headlight and wiper switches on the lower left.
Here’s a closer look at the display, gauges, and recorder. The single harness is all that is needed for all the traditional dash gauges: oil pressure, water temp, tach, speedometer, odometer, fuel level, oil temp, fuel pressure, and voltage level. It also supports display of lap times (we will be installing a lap time sensor).
