The DGauge is a digital multi-gauge that plugs into the diagnostic port on most 1996 and later Asian, European and some US vehicles and displays real-time engine data on it's color TFT LCD. Through the selection of one of 3 different screen modes, you can monitor 2 or 4 user selectable parameters at a time. As many as 25 different parameters are available for viewing, depending on vehicle support and 7 parameters via external sensors. Optimized for track use, the DGauge includes a shift light output, gear position indicator and excellent visibility in all lighting conditions, including direct sunlight. Exceptionally easy to set up and operate. With unmatched performance and reliability, the DGauge offers the most advanced technology in engine monitoring.

Shift Light - The shift light output is adjustable from 3,000 rpm to 9,900 rpm in 100 rpm increments. The output can drive an LED shift light such as the SL2A (sold separately).

External Sensors - The DGauge has 2 external sensor inputs. Sensors and sensor connection cables are sold separately.

Micro Mount - The Micro Mount is an elegant non-permanent mounting solution.

New firmware just released! We added LTF and ALV for vehicles that support it. Also, for vehicles with a MAP sensor, we added a new parameter for BP (Boost Pressure) and an auto calibration feature.

Gear Position indicator added to the DGauge. Here is a video showing the performance:

It's a bit blurry due to the engine/vehicle vibrations. Best we could do with the camera mount that we have.
