Every car owner wants to get more out of their vehicles in terms of speed and performance on the roads. And better fuel efficiency or economy and more power and torque being the most desirable aims of car owners. Now, the best way to achieve the same is through remapping or ECU tuning. But what is ECU remapping or tuning? Well, here’s the answer to this question. 
 
Remapping or tuning a vehicle can be defined as the process of making some alterations in the ECU which is the Engine Control Unit of the vehicle. The ECU or Engine Control Unit of the vehicle controls many functions like airflow, working of the sensors, fuel injections, etc. The ECU can be reprogrammed for managing these functions differently and get the maximum benefits out of it. 
 
Remapping or tuning is done in different ways in different stages. In stage 1 tuning, different aspects are taken care of, in stage 2 tuning some other ...
... aspects are considered, and in stage again some more or other functions are tuned. However, with every stage of tuning or modifications made to the car’s ECU, you can be sure of getting more power, efficiency, and torque for your vehicle. 
 
And now to make you understand all these stages of car tuning or remapping, all the stages are explained differently here in this post. Hope, it will give you a clear idea about these stages and also help you choose the right one as per your car condition, problems you are facing with your car, and your overall requirements. 
 
Here’s all about the different stages of car remapping. 
 
Stage 1 car remapping:
Stage 1 car remapping can be defined as the remapping process that is designed to remap the stock components and the ECU parameters to ensure safety and comfort and to retain the stock exhaust system, intercoolers, air intake, and catalytic converter of the vehicle. Stage 1 car remapping can be considered as the real optimisation of the stock and ECU parameters that also unlocks the potential of the ECU to release the maximum power. The stage 1 tuning can be done through the OBD port of the vehicle. In this stage of remapping, varieties of fuel specifications are also offered and alterations are made that greater power. A stage 1 remapping file is safely run with the stock hardware and is calibrated to use for different levels or amounts of fuel although it is ensured that the ECU software of your car is developed for a specific fuel grade. In some cases, you can see better fuel economy once you get back to your standard driving style and pattern and your excitement for your increased power settles down. 
 
Stage 2 car tuning:
Now, let’s talk about stage 2 car tuning. At this stage of car remapping, a certain level of hardware is required depending on the vehicle. However, there are a few basic requirements for stage 2 tuning for some specific car models. 
 
Intercooler upgrade in stage 2:
A front-mount intercooler is required at this stage of car tuning or remapping due to the increased pressure and advanced timing. This creates more heat, which means you will have to upgrade the intercooler for contracting this increase. The upgraded intercooler will have a greater core construction, a potentially bigger outlet and inlet, and a much larger surface area. 
 
Exhaust upgrade:
The aftermarket exhaust system is the second most important component of stage 2 remapping and in most cases, the entire turbo-back exhaust system is needed. This comprises a sports cat downpipe or decat, based on your intended use, along with one oversized cat-back exhaust. These need a remapping for stopping the trigger of the engine management light. 
 
The pipe diameter of the exhaust system is very important in this stage of remapping. The turbo also needs some amount of back-pressure for operating optimally, though too much can cause problems, with an excessive amount of exhaust gas temperature may result in engine damage also. So, make sure to take suggestions and advice from the experts in the car remapping company. 
 
Air intake upgrade:
It is essential to feed the car’s turbocharger with cold, and well-filtered air so that the intercooler does not have to work hard for cooling the heated-up air passing through the engine’s throttle body. In most cases, an aftermarket induction kit will be required. The induction kits are also mass-produced nowadays, making these relatively more affordable, which is a good thing as these are essential parts of the cooling upgrade in stage 2 remapping. 
 
Other add-ons may be needed depending on the vehicle:
An upgraded and high-pressure fuel pump gives an extra amount of fuel to some modern and direct injection car engines for stage 2 remapping. This means either an Auxillary fuel setup is needed or the upgraded and high-pressure fuel pump is required to keep up with the fuel demand. 
 
This is extremely important if you are going for your Audi tuning or remapping. 
 
Stage 3 remapping:
Stage 3 remapping follows stage 2 remapping. In this stage, the hybrid turbocharger, a part of the OEM, is re-manufactured with bigger internals for producing greater air capacity and airflow. This also means that the engine of the vehicle will move a greater air volume and exhaust gas at the same point to increase pressure as the OEM unit. And this allows the addition of fuel and adjustments of timing to push the engine to safe limits, making some crucial gains over the stock figures. 
 
Stage 3 remapping can be used on stock engines without the need for any forged engine. However, sometimes it is limited to what the engines can handle in their stock form. It is suggested that the forged engines must be used in conjunction with the stage 3 tuning kit for pushing the ultimate power whilst maintaining reliability and ensuring longevity. 
 
Also, there are a few after-considerations along with stage 3 remapping like the crank fixing, meth injection, and a few more aspects.
