Unless the tuning is done specifically under the approval of the manufacturer and labeled not to void the warranty, a voiding of the warranty is almost certain. While Factory Performance Parts and tuning are often done with warranty concerns in mind, this isn’t always the case with aftermarket tuning. Tuning is all about compromise, and in the case of chip tuning, this compromise is usually with reliability and safety. All these potential risks can mean serious engine damage, and this is why chip tuning will almost certainly void your car’s power train warranty. Though this also means higher levels of wear and a far higher risk of catastrophic engine failure if pushed too far. I understand that adding a tune voids the warranty but I was wondering if I kept a backup of the factory ecu tune and flashed that on when I would be going. WHAT HAPPENS TO MY FACTORY WARRANTY Simply put, no an ECU Remap performed by Diesel Tuning Brisbane will not void your factory. In the case of a higher redline, the engine may very well be capable of performing at a higher engine speed.
Should this detonation occur, the knock sensor may not be able pull out enough timing to protect the engine. Advanced timing can mean more power, but also a higher chance of potential detonation. Tuned improperly, can cause immediate and serious engine damage. Leaner fuel maps mean more power, but are far more vulnerable to a bad tank of gas or higher air temperatures. The problem from the factory’s point of view, is that changes to the ECU tuning all have a potentially negative impact on reliability. In addition, the redline and fuel cut of the engine are set at a level that the factory deems a suitable compromise between performance and reliability. Fuel and air ratios are generally on the rich side, and ignition timing is generally retarded to help reduce chances of detonation. The reason the aftermarket has such success selling chip tuning services is because of the conservative nature of factory tunes. Remember a Dealer has a lot of money invested and if they can get you to believe that what YOU DID caused the failure. If the after-market part causes a genuine part to fail then of course the manufacturer does not need to warrant the original part.
Car ECU’s are set to factory settings when sold, and have pre-programmed safeguards. In other words, the aftermarket part you fitted will not void warranty. Think of your ECU as your engine’s computer it manages ignition control, gear position, rpm and many other important parts of your car. While this route can be a relatively easy way to improve performance, it can also severely compromise the engines reliability and stability. ECU Fiddling with your electronic control unit, commonly known as an ECU, will likely result in the voiding of your warranty. This form of tuning deals with actually altering the engine’s fuel and ignition maps as well as changing the timing of variable valve timing, rev limits and speed limiters. One of the most commonly misunderstood forms of tuning is the chip tune.
