It should immediately be noted that the installation of electronic (contactless) ignition on the VAZ “classic”, despite some investments, is economically justified. As a result of the replacement, some savings in fuel consumption are achieved due to good starting in the cold season, more stable operation in idle mode and more accurate control of the ignition timing.
Although BSZ (non-contact ignition system) kits are now sold, it is still worth listing the parts required to install electronic ignition on VAZ 2106, 2101,2104, 2107, 2105, 2103:
- ignition coil (027.3705 or equivalent 27.3705);
- distributor with Hall sensor (38.3706);
- switch VAZ 2108 (036.3734);
- set of candles (A 17DV-10);
- wiring harness (ignition bundle for VAZ 2108).
How to set the seven on a carburetor
The VAZ 2107 traces its origins to the Fiat 124 and was produced in Russia until 2012
Installation Tools
For all work carried out we will need:
- key to 38;
- open-end or socket wrench 13;
- a 12 V control light with two wires attached to it (each wire is approximately 20 cm long).
The key for turning the crankshaft is designed for more careful alignment of the marks
How to work with tags correctly
There are three marks on the engine block next to the crankshaft pulley, each with its own length. You can feel these marks from the driver's side, but only strictly with the engine not running, since the pulley rotates at high speed when the engine is running! The shortest of them will mean that the ignition is advanced by 10 degrees or 10 degrees to the top dead center of the piston in the cylinder, the middle mark by 5 degrees and short - 0 degrees. You can also feel the slot on the pulley, and even on a VAZ 2107 (carburetor) this mark is sometimes implemented differently, but the main task is to find it.
Ignition timing marks
Step-by-step description with photos and diagrams
- If during the work you accidentally messed up the ignition setting, then do not rush to remove the valve covers to understand when the compression stroke begins. Do the following: remove the spark plug in the first cylinder and plug the hole with a small, tight plug made from a rag soaked in water. Having made sure that no one is standing nearby and will not be harmed by the impromptu plug flying out, in short series we turn the crankshaft with the starter for literally a split second, turning the starter on and off, and at the moment when the plug flies out with a characteristic sound from the spark plug hole, we stop turning the starter.
- Now, turning the crankshaft a little at a time by the pulley nut with a 38 wrench, we ensure that the marks on the pulley and the cylinder block coincide with the middle mark, which means 5 degrees.
- We unhook the latches from the distributor cover and look at the direction of the slider: when it is positioned as in the photo, then half the job is already done. If not, then use an open-end wrench or a 13-socket wrench to unscrew the nut, remove the distributor and put everything back in the required position.

How to set up on the injector
On the injection engine of a VAZ 2107 car, ignition timing adjustments are not required, since the setting function is performed by an electronic control unit that receives the necessary information from sensors.
Checking the correctness of data in the system
- We start the engine and start driving.
- Having accelerated the car to approximately 45 kilometers per hour, we very quickly engage fourth gear and sharply press the gas pedal to the floor.
- We listen to the engine, if detonation, or as car enthusiasts say, “knock of fingers,” is present for 1.5-3 seconds and disappears as acceleration occurs, then the ignition is set correctly, which means no manipulations are required. If detonation does not disappear during acceleration, then the ignition is “early” and you need to turn the distributor clockwise by about 0.5-1 notches. In the case when there was no detonation - the ignition is “later”, you need to turn the distributor 0.5-1 notches counterclockwise.
ADJUSTING THE IGNITION WITH A TRAMBER. (MANUALLY!) Where to turn it.
In fact, everything is very simple... first you need to find out where the ignition distributor shaft rotates when the engine is running. This is not difficult to do on any make of car; you need to remove the cover from the ignition distributor. and turn the engine with the starter or roll the car by first engaging forward gear. Once the direction of rotation is figured out, adjusting the ignition timing is simply a matter of technique. Turning the distributor body in the direction opposite to the rotation of the runner is a decrease in the ignition timing, and vice versa, turning in the direction of rotation of the runner is an increase in the ignition timing... Now you can spin. boldly
