The Banks iDash 1.8 is built for owners who need more than a single needle on a dial. It plugs into the OBD-II port, scans the vehicle for available data, and puts far more of the powertrain picture in front of you than the factory dash ever will. Instead of showing one value, it can display up to five parameters at once in configurable layouts, track min/max values in the background, and trigger custom low or high alerts on monitored data. Where this gauge separates itself is what it does with that data. The SD-card version can record up to 100 parameters at 10 samples per second, flag events during a pull or drive, and play the log back directly on the gauge. That means you can review what happened without guessing, and you can open the CSV file later in Excel or other analysis software for a closer look. It also handles diagnostics, including reading and clearing trouble codes and checking emissions readiness. And because it uses the Banks Bus Network, the iDash 1.8 can grow into a larger system with multiple gauges, added sensors, and control of compatible Banks devices. The result is a 52mm gauge that works more like a compact powertrain information center.
The Banks iDash 1.8 is presented as a universal OBD-II gauge designed to plug directly into a vehicle's diagnostic port and display a large amount of engine and vehicle data. It is compatible with all 2008 and newer vehicles, along with some models from 2004 to 2007. Installation is intended to be simple and fast: plug the connector into the OBD-II port and the gauge is ready to operate. Beyond factory OBD-II data, the unit can also work with many popular standalone ECUs, or even without engine data when paired with Banks expansion modules.
The iDash 1.8 is built in a standard 2-1/16-inch, or 52 mm, gauge size, allowing it to fit in most common gauge locations. It can be mounted in an A-pillar pod or attached to the windshield with the Banks suction-cup mount. Navigation is handled through a four-button interface intended to be straightforward and intuitive. Unlike a traditional gauge that shows only one value, the iDash 1.8 can display as many as five parameters on a single screen, using a variety of selectable layouts ranging from two to five gauges per display.
When connected to a vehicle, the iDash automatically scans for available data channels and builds a list of viewable parameters. The exact list depends on the vehicle, but the demonstration states that most vehicles provide around 60 parameters, with some offering as many as 90. These values are organized into categories to make them easier to find.
Changing a displayed parameter is done through the Gauge Selection menu. In the example shown, the second display field is changed from ambient air density to boost air pressure by entering the pressure category and selecting boost. The same menu also allows the user to change the overall screen layout. Switching from a multi-field layout to a three-gauge layout immediately updates the display to show three selected parameters.
A built-in min/max logging feature continuously monitors up to 20 parameters and records their minimum and maximum values. These logs are retained across key cycles, so they remain stored until the user manually clears them. Through the Min/Max Log menu, the user can review either the maximum or minimum values recorded for the selected channels.
The monitored parameter list is configurable. In the demonstration, RPM is replaced with engine oil temperature. Once added, the maximum log shows that the highest recorded engine oil temperature was 203 degrees F. This feature is positioned as a practical way to understand real operating conditions and to help determine useful alert thresholds.
The iDash allows custom low and high alerts to be set for nearly any readable parameter, including both currently displayed values and background-monitored values from the min/max list. In the example, a high alert is configured for engine oil temperature and set to 200 degrees F. The interface allows the threshold to be adjusted with single button presses or rapid scrolling by holding the button.
Once configured, the gauge warns the driver whenever the parameter exceeds the chosen threshold. If the alert applies to a background parameter, a small warning indicator appears in the upper-left corner until the value returns below the limit. If the alerted parameter is currently displayed on the gauge face, a warning box appears and that value blinks white and red until the condition clears. With multiple iDash units installed, the system can be configured for staged alerts-for example, separate engine oil temperature warnings at 200, 210, 220, and 230 degrees F across different gauges.
An optional continuous SD-card data-logging version of the iDash expands the unit's recording capability significantly. This version can log up to 100 parameters at 10 samples per second directly to a microSD card. Banks states that the included 4 GB card can store more than a month of recorded data. In a multi-gauge setup, the unit connected to the OBD-II port becomes the primary gauge, and that primary gauge manages the logging functions.
To configure a log, the user inserts the microSD card into the face of the primary gauge and enters the Data Logging menu. Parameters are referred to as Banks iDash parameters, or BIDs. The user can clear the current list and build a new one by selecting categories and adding multiple parameters from each. In the example, several temperature and pressure channels are added, including boost air pressure and fuel pressure. Parameters can also be removed individually from the list.
Starting and stopping a recording is done with a shortcut: holding the down button for two seconds. While recording, a blinking green LED indicates active logging. The back button can be used to insert a flag marker during recording so important events can be identified later. The example given is marking a moment when the vehicle is accelerated hard onto an on-ramp and experiences engine knock, making it easier to revisit that exact section of the log during analysis.
One of the more distinctive features demonstrated is direct playback of recorded logs on the iDash itself. From the Data Logging menu, the user can enable loop mode if desired and then select a stored log for playback. During playback, a blinking blue box indicates that recorded data is being viewed rather than live data. The presenter also changes one of the displayed fields to the log time value so the playback position can be tracked against the recorded parameters.
Playback controls allow the user to skip forward or backward by 5 seconds with the up and down buttons, or by 30 seconds when those buttons are held for two seconds. Pressing the back button pauses playback, and while paused, the same buttons step through the log in 0.1-second increments. This allows close inspection of short events. Playback can then be resumed or stopped through the menu.
In a multi-iDash system, the primary gauge controls playback for all connected units. Any recorded parameter can be displayed during playback, even if it was not visible on the screen when the log was originally captured. The example shows boost being assigned to a display field after the recording was already made, demonstrating that the stored dataset remains fully accessible. For deeper analysis on a computer, the microSD card can be removed and inserted into a PC. The logs are stored as standard CSV files, which can be opened in Microsoft Excel or other data-analysis software.
The iDash includes built-in diagnostic functions in addition to its gauge and logging roles. Through the Diagnostics menu, the user can check current vehicle trouble codes and clear them if needed. The gauge can also display emissions readiness status, allowing the user to see whether the vehicle is likely to pass a smog inspection before going to the test station.
Another standard feature is a customizable shift light. Each gauge can be configured independently with its own RPM threshold and color, allowing a staged shift-light setup across multiple gauges. The demonstration notes that this can be done with any number of gauges, not necessarily four.
Additional utility features include the ability to enter custom tire size and final-drive ratio values so the gauge can automatically correct vehicle speed, which is especially useful for off-road vehicles running non-stock tires. The unit can also display English or metric units, and those unit settings can be configured independently on each gauge. For example, one gauge can show boost in PSI while another shows it in bar. An ambient light sensor automatically dims the display at night.
The final emphasis is on expandability through the proprietary Banks Bus communication network, or B-Bus. This network allows up to four iDash 1.8 gauges to be daisy-chained together and also supports additional Banks modules and sensors. The examples mentioned include the Banks Derringer tuner, plug-and-play pressure, temperature, and frequency-based sensors, exhaust gas temperature monitoring, transmission temperature monitoring while towing, and the Straight-Shot water-meth controller for turbocharged gasoline engines experiencing knock. The video also mentions future B-Bus accessories such as power modules for controlling a light bar and wideband air/fuel ratio modules. In that framing, the iDash 1.8 is not just a digital gauge, but a modular vehicle-monitoring and control platform built around expandable data acquisition, diagnostics, and accessory integration.
