WHAT IS OBD?

On-board diagnostics, or OBD, is an automotive term referring to a vehicle's self-diagnostic and reporting capability. OBD systems give the vehicle owner or a repair technician access to state of health information for various vehicle sub-systems. The amount of diagnostic information available via OBD has varied widely since the introduction in the early 1980s of on-board vehicle computers, which made OBD possible. Early instances of OBD would simply illuminate a malfunction indicator light, or MIL, if a problem was detected-but would not provide any information as to the nature of the problem. Modern OBD implementations use a standardized digital communications port to provide real-time data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allow one to rapidly identify and remedy malfunctions within the vehicle.

The OBD system provides owners with an early warning of malfunctions by way of a dashboard "Check Engine" light (also known as a Malfunction Indicator Light or MIL, for short). By giving vehicle owners this early warning, OBD protects not only the environment but also consumers, identifying minor problems before they become major repair bills.

WHAT IS OBD TUNING?

In the engine tuning industry, three phrases are often used interchangeably. These are: 'OBD Tuning', 'Chip Tuning' and 'ECU Remapping'. OBD stands for On Board Diagnostic. To make sense of this the word port is important because without the port, on board diagnostics would not actually exist; just as it didn't exist in the 1980's. So any 'OBD port tuning' or 'obd port remap' is just engine tuning or engine remapping completed via the use of the car's obd port.

WHERE IS THE OBD PORT LOCATED?

The OBD port (On-Board Diagnostics) is basically a plug in the vehicle which can be connected to which has a self-diagnostic and reporting ability. The OBD port enables the vehicle's owner or vehicle's technician to access information relating to the health state of various vehicle sub-systems.

WHAT DO YOU ACTUALLY MODIFY IN MY VEHICLE?

We do not change any hardware in your vehicle, we just modify the operating parameters in the ECU's program or 'map'. In many cases the map stored on the ECU's processor can be accessed via the on-board diagnostics port (OBD) in the vehicle, normally found under the dashboard. In some newer models the ECU will have to be removed from the vehicle and the casing opened, our technicians will then use specialist tools to read the original map straight from the processing chip.

The technician will then upload the original map to our map writing team who will adjust the parameters to maximize the performance, fuel economy or a clever blend of both. Depending on the vehicle and ECU type the remapping process can take under an hour and if at any time you wish to return your vehicles ECU to its original default settings, this can be done easily and free of charge as we always keep a copy of the original software as a backup.

SAVING FUEL WITH OBD REMAP?

When tuners remap a vehicle, especially when fuel saving is the priority they focus on improving the low end torque in particular and widening the power-band as far as they can.

This increase in low end torque will mean less throttle pedal input is required to maintain cruising speeds, when fully laden or when on a gradient. It will also mean that the vehicle will be more comfortable in higher gears at slower speeds as well requiring fewer gear changes overall.

If you combine these factors with adjusting your driving style to make the most of the extra low end torque you will see an improvement in fuel consumption. This is most effective on turbo-diesel engines where the savings could be as much as 20%!

HOW DO I KNOW THE OBD SYSTEM IS WORKING CORRECTLY?

When you turn on the ignition, the "Service Engine Soon" or "Check Engine" light should flash briefly, indicating that the OBD system is ready to scan your vehicle for any malfunctions. After this brief flash, the light should stay off while you drive as long as no problems are detected. If so, you'll be glad to know that your vehicle is equipped with an early warning system that could save you time, money, and fuel in addition to helping protect the environment!

WHAT SHOULD I DO IF THE LIGHT STAYS ON?

There is no cause for panic. The vehicle is just telling you to seek attention soon. When you reach your destination, make sure the gas cap is not loose or missing. Always turn off your engine when refueling. If the light does not go out after a few short trips following gas cap replacement or tightening, have your vehicle serviced by a qualified repair technician soon! Delaying assistance could lead to more expensive damage.

WHAT DOES IT MEAN IF THE LIGHT TURNS ON WHILE I'M DRIVING?

If the light comes on and stays on, the OBD system has detected a problem. Your vehicle might have a condition that wastes fuel, shortens engine life, or causes excessive air pollution. If left unaddressed, these conditions could also damage your vehicle and lead to increasingly expensive repairs. For example, OBD can identify a loose or missing gas cap (which wastes fuel and contributes to smog) or engine misfire (which can lead to severe or permanent engine damage).

WHAT DOES IT MEAN IF THE LIGHT IS BLINKING?

If the light is blinking, a severe engine problem such as a catalyst-damaging misfire is occurring and should be addressed as soon as possible. You can still drive safely, but should minimize your time on the road. Try not to drive the vehicle at high speed or with excess weight (such as towing or carrying heavy equipment).

WHAT EXACTLY YOU DO WITH OBD PORT?

Most Remappers OR Chip Tuners have a modern repair shop and also we have an OBD scan tool (a small, hand-held scanning device) to diagnose the cause of your vehicle's problem. These technicians will have the proper tools and will know best how to diagnose your vehicle

The technician will connect the scan tool to your vehicle's computer (usually through a connector under the dashboard) and download information that can pinpoint the problem. The technician can then repair the vehicle based on manufacturer recommendations. OBD actually helps repair technicians do their job more quickly and reliably, helping you avoid unnecessary repairs and trips back to the workshop.

WHAT ELSE CAN I DO TO MAKE SURE MY VEHICLE IS RUNNING WELL?

Today's vehicles are highly sophisticated and efficient. OBD helps to ensure these vehicles are running in top shape, but you still need to maintain your vehicle according to the manufacturer's recommended schedule. Keep up with routine maintenance and keep an eye out for your Check Engine light. Always turn off the engine before re-fueling and always make sure the gas cap is securely tightened. You'll save money on fuel and repairs while helping to do your part to protect the air you breathe. In addition, driving as little as possible by combining trips, carpooling, walking, biking, or using public transit are all things you can do to help minimize vehicle pollution.
