Chip - tuning

So, you were interested with a theme of chip - tuning... Your engine works ideally, but opportunities of the regular program of management of you do not arrange? You are not afraid to spoil something and are ready to disassemble and collect the block of management blindly - then can safely read further.

That it will be necessary for you for tuing the favourite:

• the First and the most important: it as a matter of fact itself tuning the program for the block of management of your engine.

• the Second: the necessary tool for removal of the block of management from the automobile and its disassemblies, and also it is possible in the some people (unfortunately recently more and more often) cases a soldering iron for removal of the READ-ONLY STORAGE from a payment.

• the Third: the Device for reading the original program of the READ-ONLY STORAGE and record tuning versions of the program. As it is desirable (and sometimes and it is necessary) to have a copy of a "pure" microcircuit, for record of the new program.

• the Fourth: the turbo of engines need a manometer for check and adjustments of the maximal pressure of pressurization.

So, we begin under the order.

For specification of presence Tuning of the version of the program for your automobile it is necessary to know not only model and year of release of the automobile, but also number of the block of management, and in some cases and the version of the program of the READ-ONLY STORAGE established in the block. For reception of the given information it is necessary to read marks of the block of management of the engine. To specify the version of a software, it is necessary to open the block of management and to read contents of a label on the READ-ONLY STORAGE. After performance of the given operation it is possible to start searches of a necessary insertion. Actually it is not trivial enough task. The matter is that the qualitative software freely is not distributed, and serviceability and quality of insertions freely laying somewhere in a network or offered for small money local experts is rather doubtful. To get an insertion at large foreign tuning firms really, but it is completely not cheap (disorder of the prices makes from 600 up to 3000 $). To get the program for reasonable money more really from the firms being representatives of the large Tunings - companies, as for example at us (cost of programs for foreign cars from 200 $, and on the Russian automobiles from 15 $) as getting programs under the dealer prices, these firms frequently presume to reduce to themselves in some cases the price for an insertion interesting you. There is one more way of reception of a necessary insertion is an independent alteration of a software, using the specialized software. To owners of the Russian automobiles which are were interested in tuning, program ChipTuningPRO for change of programs of blocks the VAZ and GAS should be known. There are similar programs and for foreign cars. But besides they are distributed on a commercial basis and for example cost of a file - descriptor to program DME-editor only for one type of the block of management makes from 1000 up to 7000 $. When process of search (or purchases) will be completed - there will be the most interesting - replacement of an insertion. As the block of management is already found by you, and even is probably removed and disassembled in detail to stop on this operation there is no sense as on different automobiles blocks are established in different places. But it is necessary to consider process more in detail: it is necessary for you to define type of a microcircuit of the READ-ONLY STORAGE established in the block and to be convinced that available at you the device of programming supports work with the given types of the READ-ONLY STORAGE. As a rule, all device of programming allow to work without additional adapters with the microcircuits, used in automobiles of release up to the middle 90. Here has especially carried to owners BMW - practically in each block the microcircuit is established conveniently and for its removal it is not necessary to solder anything (yes however and on other automobiles are used a similar design...) . In modern blocks of management microcircuits of flash-memory with an opportunity of rewriting of the program without removal of a microcircuit from the block, however for reprogramming such blocks through a diagnostic socket of the automobile are used, presence of the expensive equipment is necessary, therefore we shall examine a case of removal of a microcircuit and use of the device of programming for replacement of an insertion. So, we begin! First we take an old microcircuit (if it is soldered - it is necessary to work as a soldering iron), remembering positions of a key, we insert it in the device of programming and we read - out contents of a microcircuit. (At work with microcircuits it is impossible to forget about position of a key, since it is easily possible to put the block of management out of action if to establish a microcircuit incorrectly.) We keep "just in case" the old program and we are going "to sew up" new. As a rule in machines up to 96 years microcircuits with an opportunity of deleting of the program are used by means of ultra-violet radiation. These are microcircuits such as 27С64, 27С128, 27С256, 27С512, they differ presence of a transparent window on the case through which the crystal of a microcircuit is seen. This window for avoidance of casual hit of light stick. For deleting it is necessary to remove a label, to wipe a window and to put a microcircuit under a ultra-violet lamp on 20 - 30 minutes. At the moment of deleting all legs of a microcircuit should be connected together by a conductor of a current. As a ultra-violet lamp it is possible to use cosmetic devices " PHOTONS ", lamps used in medicine for disinfection of premises or any other source of ultra-violet radiation. Erasing a microcircuit it is necessary to take into account that fact that it is possible to erase and then "to sew up" is far from being all copies. Microcircuits Flash (29F200, 29F400, etc.) can be erased by the device of programming, but it is better, if you will have similar pure microcircuit for record of a new insertion. After record of a microcircuit, accurately establish it on a place taken out, observing correct position of a key. For microcircuits with ultra-violet deleting it is very desirable to stick a window (even a slice of an insulating tape). Collect the block and, not closing a cover (in the majority of blocks aluminium short moustaches of fastening maintain no more than one opening), connect it to the machine. Include ignition, wait seconds 15 and start the machine. Usually the machine is got without problems, but in some cases there is an instability on single revolutions right after turn of a key of ignition which stops later some minutes. If all is normal, guzzle the machine, remove the block, and accurately collect all on a place. That's all! Now you owner Chip tuning machines.
