Downpipe without remapping

Is it possible to mount the downpipe without remapping the car? Find out in this article

One of the most common blocks in replacing the Downpipe is having to then "map" the car. 

Let's start from a fixed point, replacing the stock catalytic converter with a free InoxPower downpipe is the best solution you can choose for your car, and we'll go into this discussion  HERE .

But often a doubt arises about having to remap the car.

But what does "remap" mean? 

In practice it consists in modifying the  ECU  , the main control unit that controls the engine. In a nutshell, it is a software modification, which reprograms your car's ECU.

With this system you can do many things, from the simplest to the most complex.

Mandatory map when I remove the catalyst?

One of the most common modifications on the control unit is the one referring to the increase in power in Turbo engines.

To do this, we intervene on some parameters, among which we vary (increase) the pressure of the turbo and the pressure of the injector pump (they are not the only things that change, but to understand each other we will simplify as much as possible).

With this setup the engine power is increased.

But there is also the possibility of not touching these data and even just going to work on the lights that come on when you change the DPF, GPF or OPF by replacing it with an Inoxpower donwpipe.

Inevitably, having done this installation of the downpipe, your car will register errors.

The reason is simple, first the pressure changes. Without a "plug" (the catalyst), the exhaust gases are free to flow, therefore the internal pressures and the exhaust temperatures are lowered. This in itself is already a non-standard parameter which alerts the control unit and sends the car into protection mode.

In reality, the car is fine, but the control unit cannot understand why the parameters are different from those for which it was programmed.

Another problem concerns the regenerations in the case of the DPF, which with an InoxPower Downpipe will be excluded (say goodbye to the hated DPF regenerations).

Obviously also in this case it will be necessary to tell the control unit to avoid regeneration.

So as you may have already guessed, when you change the catalytic converter and install a downpipe (which is nothing more than a sports FAP or OPF), you are obliged to review these parameters at the very least.

To map or not to map?

It is clear that basically you don't have to map your car to mount a Downpipe, you will only have to optimize some parameters.

With this setup, by mounting the InoxPower downpipe you already have a power increase by default.

But we recommend that you map your car. We don't sell maps, we don't earn anything for telling you, and we've already indicated that you can choose not to.

At the same time, we advise you to do so.

If we talk about BMW, cars we have experience on, we can absolutely recommend a mapping with the addition of the InoxPower downpipe.

Because you get a lot of power without compromising the reliability of your bike.

Ok, I know that there is a belief that this procedure (the map) is harmful, that it is a negative thing, that the house has already thought of everything etc etc. 

And this isn't even the right article to dismantle yet another false myth of the ECU remap.

I will be brief and coincide with simple topics.

Many problems arise from ignorance, for example to absolutely avoid the map with the standard FAP, the problem is that nobody says it, and then there are pains...

This is perhaps the only mistake to avoid.

Having said that, first, we sell donwpipe, you can mount it with or without modification to the ECU, no advantage in advising you to map.

Secondly, the manufacturers have various problems in terms of the homologations to be respected and the reliability of the engines. The more stringent the anti-pollution approvals are, the greater the wear of the engine, the more conservative the setup must be to comply with the regulations.

If there weren't all these limitations we would be at very different power values.

Remember that the catalytic converter kills your engine and its performance. The manufacturers and the engineers who design the cars are well aware of this, but those are the rules. 

The same houses, on many high-performance cars (I'm not talking about the 114d to understand each other) themselves sell a "performance" package that unlocks more power, only through electronics. Other typical examples are those of the exact same engine, with all the same components, where the only difference is an electronic limitation.

If you install an InoxPower sports downpipe it will be your choice whether to do the map or not, we advise you to do it, because in a natural way you get the true potential that your car is able to offer you, without sacrificing reliability.
