Chiptuning vs Tuningbox
The accurate facts of our customers and could be clients become the principle objective of the writing of this article. Having read a extremely good number of professionally soundless, overwhelmingly advertising and marketing oriented, right here you’ll discover good enough and applicable facts, supporting you to pick the great option prior to purchase.
Basic Principles
1. The operation of the engine is commanded with the aid of using the computer (ECU), upon the facts acquired from the sensors withinside the motor compartment. All the sensors records arrives to the ECU.
2. The conversation with the ECU is viable threw the factory made OBD (EOBD, OBD2, CAN) provider plug, it become designed and homologised for this purpose (on account that 08.2000) This is the well-known area technology today. The unique optimization of the operation parameters is viable threw the OBD plug.
3. The chip tuning will now no longer adjust the functioning of the diagnostic instruments, the reading and resetting of the mistake records could be accomplished without difficulty.
4. There could be no lack of assure for the unique parameters may be restored.
In case of software program clean the changes required could be made free of charge.
5. A simple precondition of the engine optimization – chip tuning – is that every one parameters of the engine characteristic are to be changed in concord with each other.
Chiptuning
The digital tuning box, declared as milestone, has simple deficiencies. In the case of turbo charged automobile it cannot modify the turbo charging load, in case of a suction engine it’s going to now no longer modify the pre ignition and as such isn’t always appropriate for the optimization of the engine.
The chip tuning can most effective be completed through professionals, with adequate expert understanding and numerous years of expert experience. The optimization of the engine permits individual settings. For this activity some of special software program and hardware is necessary with non-stop updating because of the arrival of latest models of cars. For the funding involved is on the variety of millions, in case of outstandingly lower priced chip tuning the shortage of adequate technical support can rightly be supposed. During chip tuning the commanding chip withinside the computer of the automobile is reprogrammed a good way to gain higher performance and premiere operation. There isn’t any need to install eventually any electric powered circuit or box of unsure origin which would possibly suggest in addition source of error. The engine may be managed flawlessly by its personal computer as it become factory-made for this purpose. All the records of the sensors (6-eight pieces.) withinside the motor compartment attain the computer, the parameters are real, programming is completed withinside the laptop. By chip tuning there’s chance to modify every and each parameter belonging to the engine feature in concord with every other, relying at the revolution and the load. There is a personal touch among the client and the programmer and we are able to keep in mind individual requests, for e.g. aiming to enhance the factory-made low torque revolution ranges. A proper expert makes gain of his own experience ( now no longer simply promoting the products of others ) taking use of thousands of hours spent with the computer, effects of experiments, tests, achievements won via way of means of empirical techniques through numerous years. The proverb is authentic right here too “all that glitters isn’t always gold” now no longer all chip tunings are right. There are increasingly common instances, when the customer having chip tuning in his automobile, calls with troubles like: emitting of smoke, an excessive amount of gas consumption, the accelerator pedal is an excessive amount of sensible, the automated gearbox must now no longer shift to the final gear, etc. Many times upon reading out the records from the computer we have to face astonishing facts, I must say maximum decently there are nevertheless alternatively courageous people on this country… In every case we permit our clients know the errors noticed and additionally correct them. When we pay attention that factory-made chip records is to sent someplace threw the net and the tuning report might be obtained in flip that’s simply to be stuffed into the laptop, it’s far absolutely clean for us that there’s an inter mediator who has now no longer were given the faintest concept at the characteristic diagrams belonging to the engine function, and chip tuning. In these cases individual requests cannot be considered, we most effective can move our palms to look that at least a tuning similar to general parameters may be reached and the engine will now no longer be broken through settings of unknown origin. In case of a given version the identical engines can also additionally have certainly variations: e.g.: the VW Golf 1.6 model is provided with Bosch, Siemens and Marelli computer, now no longer to mention the variations in software program.
Tuningbox
What we need to keep in mind seriously in any case is: it really well worth to ask about the number of years spent on this field, for plenty self appointed “specialists” are looking to infiltrate into this industry. It is likewise a sign self appointed category when a software program of the identical make however one of a kind outfit is ready to be loaded into the pc. The following malfunctions may also take place on this case: for e.g. the idle is changed, control lamps are lid, the diagnostic units can’t speak with the pc of the automobile, worst of the case is when our automobile could now no longer even start. On the long term the most inexpensive solution may also come to be the maximum expensive, so don’t simply ask the price however additionally speak about actual chip tuning!
The tuning boxes are mass produced, in maximum of the instances sellers and retailers are promoting them, it could additionally be mail ordered and be installed even in a parking zone for it desires no expertise. However, this indicates an undisputable benefit in opposition to chip tuning from the point of view of big sales, so for the client it simply can appear to be a comfortable solution. The tuning box may be carried out universally in instances of various models and motor capacity: for a 1.three Multijet Punto the equal tuning container is suggested and bought as for the Bravo 1.nine JTD or an Alfa or a 2.three Multijet Ducato. Model unique settings are glaringly now no longer possible. Using a tuning container there aren’t any picks of fine tuning or to fulfil individual requests of clients which can be completed with chip tuning. Data from the accelerator pedal sensor additionally attain the pc, the tuning of the sensibility of the accelerator pedal cannot be completed with a virtual tuning box fitted at the airflow meter or the rail sensor. This most effective may be completed through a further tuning field established at the accelerator pedal sensor. That could mean but superfluous extra expenses and the want for one extra tuning box. A chip tuning consists of the adjustment of the sensibility of the accelerator pedal upon request, with none surcharge. The mounting and demounting of a tuning box may be completed with out expertise. The tuning box is installed among the pc and the sensor withinside the motor compartment. Modifying the signal voltage or resistance parameter of the sensor this way, fake statistics is transmitted to the pc, resulting in extra use of combustible or letting better urgent at the system. It cannot alter the rest of the engine parameters, harmonization of the distinct statistics isn’t always possible. It is simple to recognize the tuning box which controls 1 sensor: it s becoming needs to reduce 1 connection withinside the motor compartment and to insert the box in line withinside the very circuit. The operational principle of the analogue and virtual “programmable” tuning box is the same: they transmit fake data from the sensor to the computer. The virtual model performs handiest higher for the extension of the signal faking may be adjusted relying at the revolution. Summing up: analogue box = a fuse or a voltage regulator. Digital tuning box = voltage regulator which adjusts the volume of the resistance relying at the revolution. It is to be noted, that a resistance isn’t belonging to the maximum highly-priced parts…A chip or processor withinside the tuning box is essential for the operation of the very BOX and isn’t equal with the commanding chip withinside the ECU which controls the MOTOR operation. The tuning box will now no longer modify any information withinside the chip of the laptop, so the denomination as chip tuning box, or chip box aren’t adequate, it’s miles sensor tuning box correctly. There are quite higher quality tuning boxes that can lie to 2-three sensors at a time (out of 6 or 8) their rate beginning from HUF 100.000.-, however even the ones can’t modify the turbo charging. There are a few vehicle models the computer of which isn’t programmable ( those exemptions are primordially Japanese, Korean or US a few made products ) in those instances the tuning box may be an intermediate answer if we’re inclined to pay a better price for a modest output increase. In the case of turbo charged vehicles the tuning box controlling 1-three sensors will procedure greater gasoline into the combustion area, however more gasoline needs more air to provide better burning and efficiency. This extra air can simplest be received through increasing the turbo charging, however the tuning container isn’t always succesful to regulate that. This regulation may be solved through the chip tuning, if the charging output will increase with 0,2 – 0,three bars as a way to now no longer have an effect on adversely the turbo charger ( because of the manufacturing facility made reserves, massive margins ), however this could make a first rate distinction from the point of view of output and ideal burning. In case of turbo charged engines about 1/2 of as a lot increase in output and torque may be accomplished with tuning box as in case of a professionally performed chip tuning. The tuning boxes offered for suction engine vehicles procedure greater gasoline into the combustion area due to the fact they change the information signals from the Lambda test or the air volume meter, however they do now no longer adjust the pre ignition to the changed situations of operation. The essential principle of the optimization of the engine is that the one of a kind parameters ought to be changed in concord with every other. The change of a single parameter can also additionally supply a few increase of performance, however it gives a lot much less than optimal operation and the best possible output increase may want to be. The ideal burning of the extra gasoline needs more time and thus the change of the pre ignition is essential, that’s in every case adjusted in keeping with the revolution and cargo in case of a chip tuning.
Concrete example: E39 530D BMW 184LE 2002 with manual equipment shift.
The owner of the referred car called me with the trouble that after having a tuning box set up five month earlier than he got the idle unbalanced , it’s miles various with cold engine, he had already modified the injector tops ( in case of this version it charges HUF 90.000.- each ) however even this did now no longer presented him a everlasting solution. He additionally complained that during case of complete equipment when he shifts ( with out pressing the accelerator pedal ) the revolution isn’t always decreasing it appears to be “overdosed”. Upon agreeing in a date, this gentleman visited our workshop and when we finished a test drive the elimination of the tuning box followed. We may want to realize that the manufacturing unit made connector was disconnected from the sensor of the rail pressure and the tuning box turned into completely linked here, which turned into handiest capable of falsify the information of this one sensor. The regulator withinside the tuning box may be set in scale of 10 grades with a screwdriver. In the grade 10 manage lamps had been lid and the motor disabled. The customer used the box in grade placing nine and the information detected had been additionally reflecting results of this grade. The tuning box has boosted the voltage sign with 30% which expanded the same old 1350 bar compression with numerous hundred bars over! It turned into the consequence of this unrealistically excessive compression that the tops of the injectors had been deteriorated earlier than time and that the high revolution “went on” even as shifting. Once the whole thing was in place, we read out the very own software of the automobile threw the service plug. During chip tuning 6 different parameters had been modified: gasoline quantity, injection time, enrichment at acceleration, limitation of output, turbo compression and rail pressing (five% as opposed to 30). Loading of the rapid software turned into additionally made threw the manufacturing unit made OBD plug, the bonnet turned into only lifted to take away the tuning box. The issues resulting from the tuning box had been eliminated, the motor were given a better torque, acceleration turned into significantly higher in all revolution ranges, the revolution turned into accurately declining when transferring or letting up the accelerator pedal, the over spinning ceased to exist and the customer left satisfied.
The following professionally incorrect statements have been found in tuning box webweb sites and advertisements:
New! We observed this sentence in a very good print quality booklet offering a selection of tuning boxes:
“The tuning box is an external tuning solution which gets the signals from the command centre and forwards them to the injector.”
Explanation: A excellent sentence, appropriate to mislead non-professionals. The simplest problem is that it has no sense. The indicators come from the sensors (as it’s far stated in it s denomination), to the command centre and now no longer likewise. The tuning box is positioned among the sensors and the computer, it isn’t capable for something else than faking data. This isn’t optimisation of the engine! The command centre offers orders to set parameter records belonging to all motor functions (the injection amongst them). The optimization of the motor is simplest possible with the change of the commanding program.
New! „The active particle filter (FAP type) engines can most effective be programmed with digital tuning box.”
Explanation: In case of professionally accomplished chip tuning the FAP filter keeps to function perfectly. With chip tuning the air and gasoline amount may be exactly adjusted withinside the circumstance of partial load, at acceleration relying from revolution and load, with attention of the the warmth of the engine and the outdoor temperature.
„The engine needs to be dismantled at some point of chip tuning.”
Explanation: To do chip tuning the engine never needs to be dismantled. The pc and the engine are separate units, the command unit is regularly located withinside the passenger compartment and now no longer even withinside the motor compartment. (It is apparent that the “author” of the above statement lacks any expert knowledge.)
„The chip tuning is irreversible.”
Explanation: The manufacturing unit set parameters can usually be reset.
Since 08.2000 all automobiles are fitted with standard OBD plug. A 95% of those automobiles are programmed threw the service plug, reprogramming of the manufacturing unit set program normally takes 2 to three minutes. In case of the remaining 5% and in case of older makes elimination of the pc is wanted that is usually constant through four screws. If the chip of the pc isn’t always reprogrammable as is the case of models earlier than 98, the chip is to be replaced. The pc has now no longer to be dismantled even to carry out this task, most effective its cover needs to be removed. Resetting the manufacturing unit parameters in this situation will take among 15 and 30 minutes.
New! „The chip tuning exposes the engine to extreme usage.“
Explanation: During chip tuning 6-eight parameters belonging to the engine functioning are growth through 5-10% in concord with every other and those elements are summed up. In opposite to this the tuning box related to only one sensor will growth the unique setting of this single parameter with as much as 30-40%. This manner the element belonging to that specific sensor could be uncovered to extreme utilization and could must get replaced earlier than normally. It is a alternatively wonderful display while all types of virtual devices are linked to the tuning field whilst programming, however if the field can best regulate simply one sensor, must it’s a NASA pc it might additionally modify simply one parameter.
Example: What might be your choice while paying attention to music? A one loudspeaker mono “system”, with one control knob or a 7.1 sound device of eight loudspeakers every of them linked to a separate mixing console? More or less that is distinction of setting among the tuning box and the chip tuning and at complete volume the membrane of the mono loudspeaker is might already be parted while the 7.1 might be at its 1/2 of volume only. Obviously there may be severe chip tuning for automobile racing purposes, however the setting of parameters for regular use stays usually in the manufacturing unit set limits.
„A 20-30% output increase in case of each fuel and diesel vehicles”
Explanation: In case of gas fuelled automobiles without a charger (suction engines) a 12-15% output growth may be attained with chip tuning (by tuning box 5% perhaps) independently from the model. Without mechanical transformations, simply fitting a tuning box, a 20% growth of output is truely impossible.
