Our example table above is from a turbocharged engine and you can see areas of the table where VE exceeds 100. Advanced Vehicle Remapping is Australia's leading ECU file service. Another way to return the car to stock would be with the Accessport. When performing an ECU remap we typically access the cars ECU via what is car the On Board Diagnostics port which is commonly referred to as the OBD port. Here's where you want to start if you're interested in tuning your Audi yourself. But now i want to be able to tune the parameters of the cars. Yup, but if you don't know what you're doing, you could damage the engine. 7.7k. will have its own software. These usually use the OBD-II port (On Board Diagnostics). The camshaft has lobes which force valves open. A turbo can also be upgraded by either choosing a bigger turbo or getting and existing unit hybridized with improved internals. Automobile tuning program is a software application utilised by many garages for their tuning projects. Causing the air to move though an engine more quickly is another priority for the home tuner. google_ad_client = "ca-pub-4230976174889513"; First up we have to accept that there are many different types of engines.

Recently cars have been coming equipped with on board diagnostic ports which enable the uploading of a fresh map. We offer a 30 Day Total Satisfaction Guarantee. In some ECU strategies, the VE map will work in conjunction with a Lambda Target (and several other) Table. The intake valve stays closed and the piston goes back up. Yeah but when your laptop flashes "DANGER TO MANIFOLD" you shouldn't shut it and tell it to shut up, because next thing you know your floorpans are flying out and me and the mad scientist have to rip apart the block to replace the piston rings you just fried. New comments cannot be posted and votes cannot be cast. Even cars that receive relatively low power gains from remaps are going to be more lively drives. Setting up a carburettor can take a lot of practice. This is the ECU. View Entire Discussion (11 Comments) More posts from the cars community. This fuel injector will vary the amount of fuel introduced based on the amount of air being fed into the cylinder. However, most goals can be achieved by using the factory ECU.

If you do plan to go down that road, you've got a steep learning curve. This forces the used mixture out of the exhaust valve and through the rest of the exhaust.

Every ECU ( MegaSquirt, Holley, Big Stuff, etc.) These tuning guides are specific to the Accesstuner Software for each COBB supported platform. The exhaust is monitored for oxygen emissions to check whether the car is running lean or rich and if the fuel being taken in is being adjusted to match. Ultimately, how do I determine whether it does have such tune, and whats the best way to eliminate it if it does. NBA. Should you need to, we can replace the tuned file with this for you at no cost to you. Check back often for new articles and updates. New oil, filter, spark plugs need to be added. Timing when a spark is delivered and adjusted and the amount of fuel required is very different. During low load conditions these tables will be averaged and used to optimize combustion.             Don’t have any questions, just wanted to say thanks for putting this info out there.  So much mis-information on forums, good to read some solid info. You can also use a computer or laptop instead of a handheld scanner, however, you will need a kit. Because of this most aftermarket car manufactures do a great job making the set-ups very user friendly. Then the tuner has ideally to have access to a complete set of diagnostic equipment that is attached to a rolling road that allows “live” adjustments to be made to the mapping.

The lowering of the piston (with the exhaust valve closed) creates a vacuum and sucks in the air through the intake valve. Constantly analysing things like oxygen in exhaust gases, throttle inputs, ambient and engine temperatures, fuelling requirements and many more, the ECU is constantly delivering the optimum outputs by assessing these inputs and delivering information back to the car. For nearly any vehicle you can improve power, increase available torque, achieve improved throttle response and linear power delivery. Unlock Serious torque gains across the rev range.

A turbo pushing an increased quantity of air into the engine, generates a lot more power. This means the parameters for each combustion cycle are set by the one before. Even with this more precise definition we still have a wide range of what tuning can be.
