VI  Meter - Engine monitoring, diagnostic and performance data

VI Monitor is the leading engine monitoring, diagnostic and performance data correlation device available. VI Monitor will allow you to not only monitor data and engine functions normally reserved for garages with expensive diagnostic equipment, but it will also check vehicle fault codes and resets them when applicable. VI Monitor also enables you to gauge your vehicles performance characteristics including G measurements, timing readouts and Dyno testing.

With newer vehicles becoming more and more electronically advanced, it is becoming harder to give the enthusiast the information they want....

VI - Key Features:

  • Compatible with all OBD II compliant vehicles*
  • Real time monitoring of up to 15 parameters** on 3 individual gauges
  • RPM & Speed Warnings with Shift Light
  • Self-damping 3 Axis G-Sensor
  • Data Logging
  • Lap timing
  • Dyno Testing
  • Performance tests for both accelation and braking
  • Descriptive fault code diagnostics ***
  • MIL Stats ***
  • Upload your saved runs/laps to your computer for analysis using V.I.D software

VI - Compatibility

If your car was built after 2004, it is very likely to have full OBD-II compliance and you will enjoy the full functionality of VI. In vehicles built before 2004, compatibility gets a bit hit and miss, but here's a rough guide to help determine if your car is OBD-II compliant. If you are unsure whether your vehicle is OBD-II, please contact the vehicle manufacturer.

Age & Country of Origin

OBD-II compliance became mandatory for all cars and light trucks built and sold in the United States in 1996. In the UK, it's a bit more complicated.

OBD-II became mandatory for new car designs in 2000.

Models already in existence before 2000 were made compliant in vehicles BUILT after 2001.
All diesel vehicles were OBD-II from 2004.

Connector Plug

The image to the right is what a standard OBD plug looks like.
Generally, the OBD plug will be located within 3ft of the driver and is usually hidden behind an easily removable panel. Common locations for this plug is under the dash in either the driver or passenger foot well, behind the ashtray, near the internal fuse box, or in the back the glove box.

Some vehicles also have diagnostics port in the engine bay but the OBD-II port should be in the passenger compartment close to the drivers position (as above).


On some OBD compliant vehicles, there will be a label or nameplate located inside the engine bay (sometimes part of your VIN plate).

Modified Engine Management Systems

Vehicles built before the adoption of OBD-II may in some cases power up but will not initiate the engine management data stream and will have limited functionality or will not work at all.

NOTE- If you have upgraded/replaced the factory fitted OBD-II compliant engine management system you should check with the supplier of your new system whether it is still OBD-II compliant before purchasing.

Real time monitoring of up to 15 parameters ** on 3 individual gauges

Monitor various parameters like speed, revs, engine load, water temperatures and pressures as well as many more* on 3 individual easy to read gauges.

RPM & Speed Warnings with Shift Light

Avoid putting points on your licence with adjustable speed warnings. Use the RPM warnings in conjunction with the adjustable Shift Light feature to get the most performance from your engine without over-revving.

Self-damping 3 Axis G-Sensor

Highly accurate G-Sensor with built-in damping for smoothness monitors acceleration, braking and cornering G forces. Also records maximum G readings.

Data Logging

Record hours of engine and performance data on any three parameters for review. Then upload your runs to the computer for further comparison. Ideal for measuring the effectiveness of engine modifications, and recording circuit or drag race performance.

Lap Timing

Simple stop/start lap timing feature allows you to record lap times of any given session for later comparison on computer.

Dyno Testing

Using a built-in Virtual Dynamometer, VI can test your vehicle’s true net horsepower in real-world conditions.

Performance Tests for Both Acceleration and Braking

Perform breaking and acceleration tests such as 0-60, 1/4 mile and 0–60–0 to measure your car’s true performance potential. Most tests can be G triggered for unparalleled accuracy. Each test is recorded for future comparison.

Descriptive Fault Code diagnostics

Got an Engine Check light, but don’t know why? VI will not only give you the fault code number, but will also give you a description of the problem; arming you with more information to take to your garage and limiting the cost of expensive diagnostics. ***

MIL Stats

Even though VI allows you to reset fault codes yourself, it will maintain all MIL Stats including time and distance since the engine check light was activated or reset. ***

V.I.D. Comparison Software

VI Monitor ships with VI Application software for downloading and comparing data off of your VI. Compare up to four Performance tests of the same type as well as hours of logged data for unlimited parameters in Monitor mode.

Powering the VI

VI takes its power directly from the OBD-II, so there is no need to plug in a cable to the cigarette lighter socket. Having just one cable (OBD-II) for all of it's needs reduces clutter in the vehicle.
