This will usually be set up on a rolling road, where data can be analyzed on the fly and adjustments made to fully maximize your power gains.
AUDI ECU TUNING SOFTWARE MODS
If you've done other mods to your Audi and want to fully explore the potential power and minimize the safety margin that was built in then you can't beat a custom map. Without that gem of knowledge, you might end up with more power but have a power blip right in this "dead" zone.ĭifferent model revisions also require a different approach, we note that alternative injectors and turbocharger units have been used over the years, all of which will require a different map setup if they are going to work well. They are also aware of common pitfalls and idiosyncrasies, for example, some of the diesel engines have flat spots, and Audi has set the Torque levels lower on either side of this to smooth it out. Specialists are around with extensive knowledge of your Audi, and they have a wider selection of maps to choose from than a "one shop does all ECU maps" franchise.
AUDI ECU TUNING SOFTWARE INSTALL
The benefits are the cost and the fact they take less time to install and set up. They are better than the Audi ECU program, and still give a wide margin for error, and are best suited to cars that have not been modified.
There are off-the-shelf maps, where a generic map that suits all one model of Audi is used, and many franchised mapping companies will use these. Having lots of power at the bottom end can cause traction issues and will often create additional wear on the turbocharger, as it won't get time to spool down after a spirited drive. In the image above you can clearly see the high power tune in red, is only a blip and doesn't perform as well as the stock tune, but the green tune gives decent power gains through the RPM range. The only way to make a meaningful comparison is to compare the dyno printouts and see what the power gains are across the RPM range, and which one will best suit your driving style. In reality a competing map that only offers a 30hp power increase, gives more power throughout the rev range, especially in the low to mid RPM region where you need it the most. You will look better if you can claim a 40hp power increase. Comparing ECU tunes from different providersĭon't ever look at the headline power figure, often times this is just a top end blip. Generally speaking, cars equipped with DPF filters and those that meet the more stringent emissions regulations will be Siemens units. The Bosch ECU's are pretty good at protecting the engine and will trigger a limp home safety mode long before damage occurs to the engine in the event of a bad event happening. On NASP engines the gains are more modest at around 14% but if you've done other mods this can be the best way to fully extract the potential power they offer.Ī computer is plugged into the Audi OBDII port, the existing ECU data is downloaded where it can be revised, verified and uploaded back into the car.īosch and Siemens ECUs were used in Audi models over the years. You can expect a power gain of around 20-35% on turbo engines. Turbo engines generally make the best gains and a remap is one of the easiest mods to do.
AUDI ECU TUNING SOFTWARE DRIVER
If a driver is prepared to fastidiously maintain the car, thereby eliminating the wear and tear that occurs and the effect this has on performance, you can significantly tighten up the MAP in the ECU and extract more power. The engine's burn must be continually adjusted to take into account engine load, temperatures, and how efficiently the burn is.ĭifferent fuels and varying ambient temperatures can also affect how well the fuel burns and adjustments must be made to the amount of fuel used and the timing of the spark.Īudi, like most manufacturers, build in a lot of leeway in the layout of these ignition, air and fuel tables so they can cope with different climates and fuel qualities. The computer in a car engine controls many aspects of the car's ignition. "All you need to know about Audi ECU tuning"
