The real advantage of iDash is visibility. Your factory dash filters, simplifies, or never shows a lot of what matters, especially when you’re towing, diagnosing a problem, or trying to keep an eye on multiple systems at once. iDash puts that information in one compact display with five customizable pages, Min/Max tracking, custom alerts, and onboard diagnostics that are always ready. It also works as the control center for compatible Banks electronics, so you can monitor and manage devices like the Banks PedalMonster and Banks Derringer Tuner through a single OBD connection. If you need more than live data, the iDash DataMonster records up to 100 parameters at up to 20 samples per second and lets you review the event later on the gauge or in a CSV file. What really separates it from a basic scan tool is the calculated data. Along with standard OBD parameters, iDash displays Banks-only values derived from vehicle and sensor inputs, including air density and weather-related conditions. That gives you a clearer picture of what the vehicle is actually doing, not just what the factory chose to broadcast.
Kate, a product specialist at Banks, introduces the iDash as a compact instrument that calculates and displays vehicle data far beyond what a factory dashboard provides. Some of that information comes directly from the vehicle computer, but a large portion comes from Banks proprietary calculations, many of them patented. In practical terms, she describes the iDash as a window into a vehicle's health and performance because it exposes operating information that drivers usually cannot see.
She compares the iDash to an iPhone in the sense that it can do much more than most users initially realize. Customers often ask what they can monitor with it, and her answer is essentially everything. The rest of the recap is organized around her ten favorite features, moving from general usability to the exclusive calculated data that distinguishes the product from ordinary OBD displays.
One of the most useful everyday features is the ability to create five customizable screens. Each screen can display between two and eight parameters, giving the user access to as many as 40 parameters with quick page changes. The display is not limited to a fixed visual style, either. Users can change the color scheme of each page, including background colors, number colors, and bar-graph colors.
Kate recommends assigning a different color scheme to each custom screen so the driver can recognize the active page at a glance from peripheral vision. Her own example is to keep towing-related temperatures and pressures on a red screen. That approach turns the display into a fast visual cue system rather than just a dense list of gauges.
Kate highlights the min/max logging function as one of the most practical diagnostic tools for real-world driving. Customers often suspect they overheated coolant or exceeded some other limit during a climb or while towing, but they usually cannot say exactly how hot the engine ran. By setting a maximum threshold on a parameter such as engine coolant temperature, the iDash can flag when that limit has been crossed. A driver who thinks the vehicle may have over-temped can then verify it in seconds by checking the max log.
Related to that is the custom alert system. The iDash allows alerts to be set for any pressure, temperature, or speed, whether or not that parameter is currently displayed on screen. Examples include low oil pressure, high exhaust gas temperature, transmission slip, or even a speed warning for drivers who want a reminder when they exceed 80 mph. When a threshold is crossed, the display presents a large amber warning box that is difficult to miss.
Another major feature is the iDash's role as a central controller and monitor for other Banks products. Kate describes it as mission control for devices such as Derringer, Six-Gun, and Economind tuners, SpeedBrake systems, and PedalMonster throttle boosters. When an iDash is installed, these Banks devices share a single network and communicate with the vehicle computer through one OBD connection.
That integration allows the user to monitor and control multiple Banks systems from one compact display. In her example, one side of the screen is used to control and monitor PedalMonster, the other side is used for Derringer, and the center still holds three customizable gauges. Even with that information visible, four additional screens remain available. The point is not just convenience, but consolidation: one display, one network, and one OBD connection instead of multiple separate interfaces.
The iDash is not limited to standard OBD data. It can also display information from external sensors, including pressure, temperature, speed, and fluid-level sensors. Kate gives the example of a secondary fuel tank mounted in a truck bed. By installing a float sensor in that tank, the fuel level can be displayed directly on the iDash. This expands the instrument beyond factory vehicle data and makes it useful for custom setups and auxiliary systems.
She also emphasizes the physical size of the unit. The iDash measures 52 millimeters, or 2 1/16 inches, making it a universal gauge-sized instrument. In her view, no other gauge this small packs in as much data. She contrasts it with other OBD monitors that are often more than five inches wide and take up too much windshield space. Those larger displays, she argues, can become distracting, especially when they prioritize flashy graphics over straightforward temperatures and pressures.
Despite its compact dimensions, Kate says the iDash remains easy to read in real driving conditions. She specifically calls out visibility in all lighting conditions, including bright sunlight. That matters because a gauge can only be useful if the driver can interpret it quickly without struggling to see the screen.
This readability ties back to the earlier customization features. Because users can choose layouts, colors, and gauge combinations, the display can be tailored for fast recognition rather than novelty. The result is a small instrument intended to deliver dense technical information without becoming visually cluttered or difficult to use on the road.
Kate ranks onboard diagnostics as another major advantage because it can save both time and money. Through the diagnostics menu, the iDash can check the cause of a check-engine light and clear the code without requiring a trip to the dealership. She describes it as a professional-grade diagnostics tool that is always plugged in and ready.
That constant availability is important. Instead of waiting to connect a separate scan tool after a problem appears, the driver already has diagnostic access in the vehicle. For owners who want immediate fault-code information and the ability to clear codes after repairs or troubleshooting, the iDash functions as more than a gauge display; it also serves as a permanently installed scan tool.
Kate says data logging is the feature that most clearly separates the iDash from other OBD gauges on the market. She explains the distinction between the iDash SuperGauge and the iDash DataMonster: the two units are physically identical, but the DataMonster adds data-logging capability. With that feature, it can record up to 100 parameters at up to 20 samples per second for more than a month using the supplied microSD card. The card is inserted into the slot located under the Banks logo.
The value of that logging becomes clear when diagnosing intermittent problems. Kate uses transmission slip as an example. Slip can occur so quickly that a driver may never catch it live, but the iDash can record it. Once back home, the user can play the data back directly on the iDash or remove the microSD card and open the CSV file in Microsoft Excel or another data-analysis application. In her view, this makes the unit far more capable than typical data loggers, many of which cost more than $2,000, offer lower data rates, and still do not provide Banks proprietary calculated parameters such as manifold air density.
Kate's top feature is the iDash's exclusive calculated data. She explains that every OBD gauge displays PIDs, or parameters broadcast by the vehicle computer to any scan tool. The iDash can display those standard parameters as well. On her example screen, the parameters shown in white are the ones any ordinary OBD tool could display.
What sets the iDash apart are the red parameters, which she says can only be displayed by the iDash. Banks calls these BIDs, or Banks iDash parameters. Rather than simply repeating what the vehicle broadcasts, these values are calculated using the vehicle's internal sensors or optional Banks sensors such as the AirMouse portable weather station. According to Kate, the iDash calculates and displays more than 150 of these exclusive parameters.
She gives weather and air-density data as a concrete example. Racers often tune according to ambient weather conditions, and the iDash can display calculated values such as ambient air pressure, density altitude, and ambient air density. It can also calculate air density inside the intake manifold and at the intercooler outlet, which she identifies as iDash-exclusive capabilities. This is the clearest expression of the product's purpose: not just showing raw vehicle data, but performing the math needed to turn sensor inputs into more useful engineering information.
Kate closes by noting that the iDash is available for just about any car or truck. It can be purchased as a standalone instrument or paired with Banks tuners, brakes, and throttle boosters. That flexibility means it can serve either as an independent monitoring and diagnostic tool or as the central display for a larger Banks-equipped vehicle system.
Across her ten favorite features, the recurring theme is that the iDash combines compact packaging with unusually broad capability. It offers customizable gauge pages, min/max tracking, configurable alerts, integrated control of Banks devices, support for external sensors, built-in diagnostics, high-rate data logging in the DataMonster version, and more than 150 exclusive calculated parameters. Taken together, those features explain why she presents it not as a simple gauge, but as a comprehensive instrument for understanding vehicle health and performance.
