Autos.com - Excessively hot weather can be far more unforgiving to advanced timing and leaner fuel maps than cold weather, and an engine running higher compression or aftermarket cams will need a radically different tune than a stock engine. All of this will result in lower power output, high EGTs, pre-ignition or knock and puts a lot of stress on the engine causing premature wear, and over time lead to catastrophic engine failure. And believe me with unsafe tuning practices, problems happen quickly and they can cause major engine issues like cracked pistons, head gasket failure, bent/broken rods, bent cranks and pistons exiting the block. This one, for example, is designed for Honda's. Just make sure your engine internals are ready for the added boost, otherwise you may end up with a hefty bill.

Unfortunately, not everyone is the same, and for some, a car is just a piece of metal that gets them from point A to point B. This is due to the cost of running a stand-alone ECU. The cost of remapping a car varies between different tuning companies.

my friend gave me tuning file he used. However, do your research as some ECU tunes can void your warranty and insurance policy! Also since JMTC focus/specialize on the Mini Coopers (and cars with the same engine) and has a lot of experience on these cars, turbochargers, engines, and ECUs. Adding more boost to any car either by adding a turbo or increasing its size is the most common bolt-on modification today.

However, before you go about getting the first ECU tune you set your eyes upon, we really recommend doing your research extensively. OBD2 connectors or scanners can also display live engine data that some on board computers won’t show. Another great bonus with ECU tuning is that you can purchase a cheaper model from a manufacturers’ range (find cars for sale), and have your ECU tuned, to produce a higher-performing vehicle compared to the manufacturers’ highest performance model in the range! Making power is all about getting more fuel and air into the engine however when you cheat and use timing to make a name for yourself you show a blatant disregard to your customers and concern for their cars.

Simply put, it is the process of altering the background information contained in the engine computer to change the way that the vehicle performs. Just so you know, we may receive a commission from some of the sales or links on this page. But how did it get there? You supply the reprogramming company with information about your car and what modifications are installed, and they reprogram an ECU with a more optimized data table. These offer the most adjustability and precise control, but are the most difficult and complex to install and understand. JMTC understands how to make safe power without taking shortcuts or risks with our customers cars. But I have found I would like more power when needed. I would say to start with half the hp increase (if you guys have the tools to do so) and then slowly go up to see if your car reacts in a weird way. Forged pistons are only designed to hold up to the stresses of increased pressure created by extra boost and high compression forces of a high-performance engine. The factory ECU’s actually have limits as to what can be changed and what cannot, and often there are things that a tuner may need to change to get the best performance but will be blocked by the factory ECU unit. Aftermarket computer tuning allows for precise and custom computer controls over engine conditions and processes. Especially if you have any supporting modifications.

It is often because of situations like these and their resulting engine damage that the manufacturer’s Warranty is generally voided by installing a performance chip. Also car gets 5w-40 and I also wait after cold start about one minute before I start driving and atleast first 10 minutes, I drive as calm as possible (no overtaking and no more then 3k rpm). Once you start combining all these aftermarket upgrades with a manually tuned ECU, you will start to see huge power and torque increases.

With more air going to your turbo, supercharger, or directly to the engine, there needs to be more fuel to balance it out so the vehicle doesn't run too lean. Usually not taking any more than half an hour to install, a flash tune is a pre-made tune file that gets uploaded to your ECU to give you the best performance and economy for your vehicle. Especially if the car has multiple upgrades that supply extra fuel, air, like a big turbocharger or intake system. Instead of 15.000km do it every 12 oder 10.000 and you should be pretty fine. As far as I know, antilag shouldn't be there! In our personal opinion, ECU tuning a naturally aspirated vehicle is not necessary as there are very minimal performance gains that you can receive, that is unless you have an 8 or more cylinder engine, some great power gains can be made with the bigger engines. Think of your engine’s computer as a telephone operator connecting calls. ECUとしてはノーマルの状態の様です。 ここからまずは新しい端末を紹介します。 端末としてはこんな感じの大きさや画面です。 車両に接続してTuningを選ぶと こちらが任意に入力したデーターとノーマルデーター（Original File）が表示さ share. I added about 10lbs unsprung weight per wheel and I would like to recover the lost torque and fuel economy if I can. Powered by BigCommerce. If you enjoyed this article please consider sharing it! With a stronger mixture of air and fuel in the combustion chamber, you will need upgraded spark plugs to take full advantage of the ignition.

Not to mention the time it takes to completely reprogram a new ECU to the vehicle. I am just worried about my little engine but I also want more power. Stage 1+ means just better air filter, right? What can actually kill parts if not properly prepared for is 2step/antilag.

This reckless shortcut strategy only leaves you holding the bag as every acceleration shortens the life of your engine and sometimes ending it instantaneously. Why You Should Choose an Aftermarket ECU and How to Choose, How to Improve Gas Mileage with Aftermarket Parts, How to Choose the Best Car Radio Amp for Your System and Situation, How to Choose an Auto Body Collision Repair Specialist. A car is only as safe as the driver. Thank you if you use our links, it will help us greatly and we really appreciate it! Even worse are the cheater tuners, that play the "I have the best tune because I make the most power gains". For example, a car is fitted with an aftermarket air intake and injectors, which will bring the engine more air and fuel, however, the standard ECU map doesn’t adjust to these modifications, so the performance modifications will not give any performance gains. As far as I know, everything on stock BFB should be okay and if I flash with KESS V2 (he will be on phone with me), I should be safe, right? Ultimate Checklist Including a Free Downloadable List! It’s really hard to say if it is worth it or not as it depends on the person’s circumstances and their vehicle. It will store multiple tune files, offer on-board logging, and display real-time data.

Because a tuner cannot properly anticipate the weather, fuel quality or pre-existing modifications to an engine, they can only give a generic tune based on compromises made by the manufacturer. Although it may seem like a dream come true to be able to throw an extra chip into your engine computer to magically produce more power, this is almost never the case. This ECU tuning option is more popular on race cars, or high budget modified vehicle builds. There are a few common options when it comes to altering the performance of your stock ECU. With this kind of tuning ECU will have no way to monitor knock, the ECU won't re-write the map to a safe condition, and it won't cut the fuel when the ECU detects an engine killing condition. Some even incorrectly advance the timing straight across all maps, increasing the chance of pre-ignition, detonation, and stressing the engine. There is a good way and a bad way to tune a car. The more complaints, the lower the rating for a manufacturer, and the fewer future customers a manufacturer receives.
