It is controlled by the head electronic unit - the controller. It provides a special survey line (K-line) for diagnosing and troubleshooting, as well as obtaining data on fuel consumption. For this purpose, cars are equipped with a so-called diagnostic plug, which opens up wide possibilities for retrofitting (at the discretion of the owner) of the car with a computer capable of "reading" injection system errors and analyzing route data. There are many computers on sale that are suitable for installation on the center console “ten”, and remote, with wires. Where to put this, you decide. All computers receive information from the K-line.

Having decided to try out several modern models in the business, we limited ourselves to those that are installed in regular places on the car. The choice fell on "Multitronics-Comfort E10", "Gamma-Intellect 112", "Navigator" and "State 112x3".

Subject VAZ 2110 had a computer installed at the factory, but he read only route indicators - there was no K-line wire on the block for him. The reasons can be guessed: apparently, the “concern” about the car owner comes down to driving him to the service for any reason! This did not suit us, and we restored the K-line: wire the computer connector and the K-line socket in the diagnostic connector a minute!

First surprise! Of the four computers bought, one - “Comfort E10” - “just like that” can not be connected to the standard connector. I had to make a simple adapter (we hope that the reader will be one of the craftsmen!). The other three devices are connected without problems.

All four cope with their functions perfectly - they confidently “read” both diagnostics and route indicators. Well, what about ergonomics, ease of use? From this point of view, a full-time computer is very good, but what's the point in it if the diagnosis is not subject to it?

The last three computers are not as convenient as Comfort E10. So, the “Navigator” has eight (!) Command buttons on the bottom, just try to press the right one and not get two at once! To touch it - a very long time, in addition, it distracts from driving. Even worse, try to see what is required (at night it is generally impossible - the buttons are not illuminated).

“Gamma” and “Staff” … The buttons are large, flat, but tight. True, highlighted, and the manufacturers took care of the symbols on them, there is less risk of jabbing a finger past.

But - stop! After talking about the buttons, we almost forgot about the displays. There are problems: the regular place of the computer on the "top ten" is located low. Apparently, this was taken into account in the factory computer - its readings are quite readable. The picture also looks acceptable in Comfort E10. The rest of the products are “not up to par” in the literal sense of the word: in order to read the testimony properly, you need to bend over … Nonsense! Color is also important here: black on yellow and red on black are easy to read. The testimonies of the rest are white in blue! - even at night slurred.
