Prosport Performance Gauges consist of two important elements: the latest trend in Asia and hottest design in USA. Great importance is attached to the experience of users and the quality of the product, from the design of the dial and the shell to the internal movement, etc., which are details that cannot be ignored.
The SM Series gauge range offers a similar classic face design to the BF Series but adds a programmable warning alert and peak recall functions. All gauges feature a dual colour backlight and can be changed between White and Amber during installation. All gauges in the SM Series range feature a digital stepper motor to drive the gauge movement and and include an external electric sensor where necessary.
Digital Stepper Motor Movement
Stepper motor movement represents the pinnacle of single gauge technology and provides the highest level of accuracy, precision, responsiveness and durability. Each instrument is controlled by a microprocessor printed internally on the circuit board, which allows incredibly fast calculations and many other particular functions not seen in other instrument types. These gauges send units for the ultimate in accuracy by utilizing laboratory grade, no more than +/- 1%. To further increase accuracy, every time the gauge is powered up it will zero calibrate to assure that it will always remain as accurate as it was the day it was made.
Prosport use two different digital stepper motors; Swiss-made stepper movements offer a more affordable yet precise option while the Japanese-made stepper movements are faster and noiseless. SM series gauge utilise the Swiss stepper motor.
All pressure and temperature gauges include an electric sensor so you do not need to run air or fluid hoses into the cabin directly to the gauge. Other gauges (AFR and Volt) are wired directly to existing vehicle wiring.
Opening Ceremony
Each SM Series gauge performs an opening ceremony when powered on. During this ceremony the needle will sweep to each limit and self calibrate. See below for a video of this in action (note, external warning light shown, sold separately. Amber/White gauge shown in video):
Warning and Peak Functions
The SM Series offer two additional functions: Peak Recall and Warning. The Peak function saves the highest value the gauge reached while driving and after pressing the Recall button allows this value to be displayed on the gauge. This Peak value can then be cleared after viewing and will automatically record a new Peak value.
The Warning function is fully programmable using the front button and the warning value can be set anyway within the gauge display range. If the gauge exceeds the set Warning value the gauge can beep, change colour or do both to alert the driver. This is ideal as you do not need to take your eyes off the road to check the gauge to ensure it’s in a safe range.
Dual Colour
Prosport SM Series gauges are able to be changed between two colours during installation by using a specific wire for power. Alternatively, the headlight switching wire can be used to change the colour. For more information see wiring details below.

Smoked Lens
All SM Series gauges feature a smoked lens which appears almost completely black when the gauge is powered off. Once powered on the display is completely visible.

Daisy Chain Installation
Prosport SM Series Gauges have an additional feature which allows them to daisy chain power from one gauge to the next. This greatly simplifies installation, as only one gauge needs to be wired for power and ground while the others can simply link to this gauge and chain from one another using the included daisy chain wire.
Signal/sensor wires will still be required for each gauge separately.
Included Accessories
Each SM Series Gauge includes the following:
*Additional accessories may be included for each particular gauge model. See details below
Optional Accessories
Additional accessories may be required to finalise your gauge installation. See below for some examples which are sold separately:

Wiring
Each gauge includes a universal, non-terminated wiring harness which requires professional installation, however products such as fuse taps (sold separately) can be utilised to simplify installation. In-line fuses (sold separately) are recommended to protect gauges from power spikes.
Some Prosport Gauges allow for auto dimming when wired to a headlight switching wire (see table below for dimmable models). Alternatively, if gauge supports colour changing functionality via wiring harness this can be incorporated so that turning on the vehicle headlights will change the gauge colour. See table below for wiring details:
| Wire Configuration | Headlights Off | Headlights On |
| White Wire – Connected to 12V Accessory Power | White Backlight Colour | White Backlight Colour |
| Orange Wire – Not Connected | ||
