Frequently Asked Questions

How do I wire this gauge into my dashboard without cutting factory wires?

Wire this gauge using the pigtail harness and T-tap connectors so you never cut factory wires. Connect the red lead to a switched 12-volt source, black to chassis ground, and the signal wire to your sender. Most gauges from Atech Motorsports use a 0-5 volt or 0-90 ohm input range. This gauge fits 2-1/16-inch or 2-5/8-inch openings with an LED backlight rated for 30,000 hours of life. This gauges component delivers accurate engine monitoring for your vehicle. These gauges are engineered for precision data logging.

What range does this gauge measure for oil pressure or water temperature?

This gauge measures 0-100 PSI for pressure or 100-280 degrees Fahrenheit for temperature with ±2 percent accuracy. Digital gauges sample at 10 per second with 0.1-unit resolution, while analog steppers offer 1 percent repeatability. This gauge runs on 12-16 volts and the sender uses a 1/8-27 NPT thread. No calibration is needed since it is factory-set for accurate readings from this gauge. This gauges component delivers accurate engine monitoring for your vehicle. These gauges are engineered for precision data logging.

Does this gauge include a sender and all needed mounting hardware?

Yes, this gauge includes the sending unit, harness, bracket, and an LED backlight rated for 30,000 hours. Mechanical gauges have a 6-foot capillary tube and pre-flared fittings for oil or temperature ports. The kit also includes a brass adapter for 1/8 to 1/2 NPT port sizes to fit your engine block. All hardware handles underhood temperatures up to 250 degrees Fahrenheit for this gauge. This gauges component delivers accurate engine monitoring for your vehicle. These gauges are engineered for precision data logging.

Can this gauge mount in an A-pillar pod or universal gauge holder?

Yes, this gauge fits standard 2-1/16-inch or 2-5/8-inch gauge pods from AutoMeter and other brands. The shallow-can design is 1.75 inches deep for A-pillar, column, or dash-top positions. The 18-gauge wires extend 36 inches from the gauge body for flexible routing. Leave 0.5 inches behind the gauge for connector access when mounting in a pod. This gauges component delivers accurate engine monitoring for your vehicle. These gauges are engineered for precision data logging.

What will this gauge tell me about engine health while driving?

This gauge shows oil pressure below 10 PSI per 1,000 RPM or coolant above 230 degrees Fahrenheit in real time. A 5-7 PSI idle drop signals worn bearings, while 240-degree spikes show cooling failure. Monitoring this gauge catches problems early and prevents $3,000 to $6,000 in engine damage. Normal readings from this gauge confirm your engine is running safely. This gauges component delivers accurate engine monitoring for your vehicle. These gauges are engineered for precision data logging.

Will this gauge work with my aftermarket ECU or standalone computer?

This gauge works with Holley, Haltech, MegaSquirt, and other ECUs using 0-5 volt analog signals. The sender needs a 5-volt reference and returns 0.5-to-4.5 volts for the measured parameter. Map the output curve in ECU software to match the sender calibration table. This gauge gives readings within 1 percent for accurate data logging and tuning sessions. This gauges component delivers accurate engine monitoring for your vehicle. These gauges are engineered for precision data logging.
