You bought a vehicle some time ago and are not satisfied with its performance? You have decided on the lower performance model for cost reasons and would now like to retrofit?
Regardless of the background, drivers have several questions about the desired performance increase. A very explosive one, which divides the tuning industry into two camps, is that of the choice of tuning. The question keeps coming up: Do I have a chip tuning via the OBD interface or do I buy a tuning box?
Right away: there is no clear winner in this “duel”. Because these are simply two different approaches. If you want to draw parallels to sport, you can compare this roughly to a direct and an indirect free kick in football. The Tuningbox is an additional control unit that is installed in the engine compartment, while the performance increase is achieved by overwriting the software in the engine control unit. To the exact function modes of the two chip tuning types somewhat later more.
Especially the hardliners of the classic chip tuning method are considered as hard critics of the so-called chip tuning boxes. But how did the bad reputation of the chip tuners offering tuningboxes, which developed in some parts of the scene, come about?
The answer is quickly found. Poorly optimized chip boxes can be produced with hardly any effort and at very low cost. Dubious chip tuners have therefore started to sell such boxes at unrealistically low prices at petrol stations, flea markets and via various online platforms. Such “tuning boxes”, which do not deserve the name in reality, have only one purpose: fast money making.
After installation on the test bench, such products sometimes achieve even minimally worse values than in their original condition. In such cases, the promised increase in performance can definitely not be spoken of. And that is still a stroke of luck, because in the worst case, NoName boxes can even cause large parts of the engine to break down for a ridiculously low price.
Such suppliers have unjustly damaged the general reputation of the tuning boxes and, due to the flooding of the market, have also made life even more difficult for serious and reliable chip tuners. Therefore we can only strongly advise against buying a box from such suppliers, who offer far below the usual market prices.
Tuningbox vs. OBD – the installation
In addition to the functionality, the Installation an essential element, which is the difference between these two chip tuning methods. Modern tuning boxes such as those from Maxchip can be done in about 5-10 minutes without outside help, thanks to innovative technology and instructions in pictures and writing included in the delivery.
A little bit different is the OBD chip tuning installation. However, also in this area has developed in recent years to the positive. So it was until recently still necessary to visit the supplier directly or a partner workshop in the context of an OBD tuning. Meanwhile, the technology has also in this area already progressed so far that you can install an OBD tuning comfortably from home. The procedure is also quite simple, although it involves several steps:
1 – Order from a reputable supplier of OBD tuning.
2 – Receipt of the product and instructions the following working day
3 – Connect product to OBD port and read vehicle data
4 – Upload read out data via Windows device and send it to the file database.
5 – get back optimized data within a maximum of 72 hours (in exceptional cases a little longer)
6 – Upload data to the product again via PC, connect via OBD port and transfer to the vehicle.
7 – short break-in and benefit from the extra performance
Between ordering and using the Chiptuning are thus ideally 4-5 working days, while with the purchase of a tuning box already few minutes after the supply the full achievement profit can be used.
Which chip tuning is right for me?
Particularly people who are making their first experiences with the topic of tuning and performance enhancement often ask themselves whether Tuningbox or OBD tuning is better suited to your vehicle. Also here it is difficult to make a general statement, because it depends strongly on the respective vehicle model and the individual driving behaviour of each person, which of the two methods the performance gain is greater.
The purchase of a tuning box, for example, is always the better option, if it is planned to sell the car at a later date or to use it only temporarily. Because in this case it is sufficient to remove the Chiptuning Box from its slot and for the buyer the car is directly back in its original condition. On the other hand, the production of the standard condition is connected with a little more effort, because the original data must be imported into the vehicle via the OBD interface.
If you are unsure which of the two types of chip tuning is the right one for you, it is best to contact the chip tuner you trust. An honest and serious tuning provider will explain to you in detail which tuning measure would be the best for you.
Where do I save more fuel?
This question is also justified and can be read again and again in various forums and social media. Basically, it should be said that both with OBD tuning as well as through a performance increase via the box a orderly fuel saving is possible. The differences between the two variants are not so exorbitant in this area, but the use of a tuning box can save more fuel, at least in theory.
With this tuning product, among other things, the injection timing and injection pressure are specifically adjusted via the auxiliary control unit so that optimised fuel consumption is possible.
How high these savings actually turn out, however, is difficult to predict in most cases. Since despite the adjustments, the respective driving style still has a corresponding influence on whether and to what extent you can benefit from the fuel savings.One Depending on the chip tuning selected and the vehicle, savings of between 5 and 15% compared to the previous consumption are within the realistic range.
The functionality of Tuningbox and OBD Tuning
Let’s take a closer look at the different functionalities of the two chip tuning variants. First of all to the tuning via box. Here we have to differentiate between Common-Rail Turbo Diesel vehicles and models which have the pump-nozzle technology.
In the case of a common rail turbo diesel, a sensor measurement is carried out which ensures that different instructions are forwarded to the individual vehicle components via the engine control unit for the appropriate situations.
Our Maxchip Chiptuning Tuningbox serves as an intermediate control unit, takes the individual measured values and adjusts the values such as the boost pressure or the injection quantity in such a way that these are optimized to the engine control unit and as the next step then passed on to the engine. Which components are changed and to what extent depends strongly on the respective vehicle model. This is because every vehicle requires individual adjustments in order to achieve a maximum increase in performance and the possibility of reduced fuel consumption in the end.
If necessary, diesel vehicles with built-in pump-nozzle technology can be tuned via an additional control unit. In this case, we bring about a gain in performance by increasing the injection quantity and boost pressure within a harmless range.
In contrast to common rail vehicles, the tuning box is installed directly at the injectors. An immediate readout from the engine control unit is thus possible, which aims at optimizing the various components. These optimised values lead to a recalculation of the engine control unit including the transfer of individually adapted data to the engine.
For all vehicles that are optimized with the Tuningbox, the 100% control of the engine parameters remains exclusively with the engine control unit of the manufacturer.
The function of OBD tuning
The OBD tuning for this in direct comparison takes place without the installation of additional hardware. Because with this form of tuning, the data is not optimized by an external device, but directly via the software. As a customer, this saves the installation of a box or other devices or conversion work directly on or around the engine. In contrast to this, there is a direct intervention on the data from the control unit.
For this purpose, the OBD interface, which is now installed in every vehicle, is used for reprogramming. The standard data is read out from a vehicle via a dedicated OBD-2 cable. These are then overwritten and individually adapted by a professional chip tuner using special software, so that the individual engine parameters are ideally adapted to the customer’s wishes. There are many different possibilities available for this, from changing the accelerator sensitivity to CAT deactivation. In contrast to a tuning box, every customer receives a tuning product tailored to his needs as standard.
OBD tuning for one – Tuningbox can be used for several vehicles
Of course, it may be very convenient for the end user if he receives a performance enhancement and adaptation already tailored to his vehicle. However, this is also associated with a considerable disadvantage.
Because of the high degree of individuality, such OBD tuning can only be applied to the vehicle for which it was programmed. In direct comparison to this we have the Tuningbox.
This works with integrated AI technology and thus automatically adapts to the vehicle intended for it after installation and connection. So it is sufficient to buy one single chip tuning box from Maxchip and it is then actually usable for more than 30.000 different vehicles of the following brands:
For this purpose it is already sufficient to remove the tuning box from one vehicle and to plug it in again in another.
With an OBD tuning, on the other hand, after buying a new car, for example, a new, individual tuning to exactly this vehicle is necessary.
Other differences between OBD and Box
As already mentioned above, in classic OBD tuning the optimization and adaptation is carried out in advance for the respective vehicle. These fine tuning possibilities are not provided in advance in this volume in a tuning box, but with the help of an app control the engine behaviour and the tuning can be adapted to the desired situation. For example, the tuning mode of a box can be conveniently changed using an app. This is particularly practical when you are planning to drive a few kilometres in the city after a long motorway journey. In contrast to OBD, the Tuningbox also offers a so-called boost mode. This enables a short-term surplus of power and thus makes it easier to overtake other vehicles, for example.
Another difference between the two tuning variants is the VMAX cancellation. This option is only available to customers within the scope of OBD tuning.
However, there are also a few points that make the two measures one. Neither of the two measures will lead to a subsequent increase in taxes, and the exhaust emission values will be complied with in both cases, so that you as a customer will not have any problems with the exhaust emission test.
Conclusion: Tuning is versatile! span style=”font-family: inherit;”>span style=”font-size: medium;”>
As already mentioned at the beginning, this is in no way intended to be an “evaluation” of the individual tuning options. However, we also drastically oppose the opinion held in small parts of the tuning industry that tuning boxes have no right to exist. With a professional chip tuner like Maxchip, depending on the vehicle, up to 35% performance increase can be achieved.
