Stage 1 is a true optimisation of the stock vehicles parameters within the ECU to unlock the potential power that the manufacture has left on the table. Stage 1 remaps come with a variety of fuel specifications which will result in a greater power result. A stage 2 remap requires a certain level of hardware depending on the vehicle, however there are some basic requirements that we will touch on that could be required as an extra for stage 2 on certain car models.
A performance intercooler is something that would be required at this level of tuning due to the increased boost pressure caused by the ECU tune. This, in turn, will create more heat, meaning you will need to upgrade the intercooler to provide your vehicle with a far greater core construction, a larger surface area and potentially a bigger inlet and outlet from the intercooler.
An aftermarket exhaust system is another key component of a stage 2 remap and in most cases a full turbo back exhaust system is required. This will comprise of a decat or sports cat downpipe, depending on your intended use, coupled with an oversized cat back exhaust. The pipe diameter of your exhaust system for stage 2 remapping can also be very important and depends on several things such as power expectation, engine displacement turbocharger, size and so on.
The turbo will also require some back pressure to operate optimally, however too much can cause issues with excessive exhaust gas temperatures and could result in damage to the engine so be sure to take the advice of your chosen tuning company.
Another important component for a stage 2 remap is an aftermarket induction kit , which are now commonly referred to as stage 1, stage 2 and stage 3 denoting what level is required to match the remap you are aiming for. Stage 1- non intercooled stage 2- intercooled stage 3- was standalone ECU intercooled..

One of the side effects of compressing air is that it raises the temperature of the air. One really is not needed until you get over about lbs of boost in our cars, since we have such pitifully low compression in the U.
Crap, I just re-read your questions and I think you already knew the answer I just gave you. This also helps to avoid detonation by keeping the mixture correct. Please log in or register to reply here. Similar threads B. MPS gen 2 dyno run. Stage Not making expected bhp. Replies 4 Views 1K.
On many cars, you can fine-tune Revo remaps for different quality fuel along with other settings. You can buy an extra bit of hardware that lets you switch between these settings. On top of that, you can add a high-quality air intake. At the back of the car, any high-quality cat-back exhaust will free things up a little bit. Stage 2 can be a little different between cars, depending on what their weak spots from the factory are, but the common theme tends to be removing limiting bits of the exhaust in combination with software that takes advantage of this.
As with stage 1, the remap will increase power. It also takes care of the different performance from a sports catalyst or de-cat pipe. Fitting this hardware without a remap will normally result in the engine reading the altered readings from the exhaust sensors as a fault and displaying the dreaded engine management light. Because of all this, a stage 2 remap is normally different to stage 1 and must be installed at the same time as fitting the new hardware. On most petrol turbo cars, this is going to start with the downpipe.
This is the section of exhaust directly behind the turbo. Turbos are at their most efficient with as little restriction behind them as possible. This means any opening out of this section of exhaust can unlock serious power gains. A de-cat pipe replaces the original catalytic converter with a straight through pipe.
A sports-cat replaces the original catalytic converter, but with higher quality, more efficient one. An e-marked, road-legal sports-cat is the only legal option on UK roads. The standard software the engine comes with is only really tuned for the original catalytic converter, so stage 2 normally means software that specifically takes advantage of the increased gas flow on offer. Again, as with stage 1, an uprated air intake is definitely on the cards, and because you can get much more exhaust gases through the turbo you definitely want to make sure the turbo is not being restricted by the original air intake.
You also want to make sure that the air going into the engine is as cold as it can be. Depending on the car, replacing either parts of the original set-up or swapping it out entirely may be the way to go. An upgraded intercooler may well be on the cards, too. This is a type of air-to-air radiator that cools the air coming from the turbo before it goes into the engine. Squeezing air through the turbo heats it up, so cooling it back down is important. There are two main benefits on offer here. Firstly, colder air contains denser oxygen, which is what your engine needs to burn petrol.
More oxygen can enable it to make more power, especially if remapped to do so. By better cooling the air going into the engine, you can help reduce how much this happens. Engine and gearbox mounts are designed to flex and twist.
Once you start upping the power the engine makes, they can start to flex more than you want them to. Replacing the floppy originals with stiffer aftermarket items can prevent this flex from robbing you of power. We carry a wide selection of these from brands including Vibratechnics, Powerflex, and Revo. Revo quote gains from 55HP up to 90HP depending on what settings are used with their software. The required hardware for their stage 2 software includes a full turbo-back exhaust with a sports-cat and a high-flow air intake.
They also recommend an uprated intercooler , uprated engine mounts , and an uprated throttle pipe. While these items are not considered essential for the remap to work, they will definitely help performance. Your choice will likely come down to what noise is preferred. As you push the engine past what it was originally designed to do, various components that were quite happily doing their job at a lower power level will start to need replacing with higher rated parts.
Exactly which components vary from car to car. You may not need any of these on your car. The remap software vendor should specify what you need — ours certainly do! As power levels increase, so too does the amount of fuel the engine requires to make that power.
At some point as you increase the power of the engine you will need to fit higher capacity fuel-injectors.
