Finnish simulator May Summer Car (MSC) has long ceased to be just a game - for many car enthusiasts it is a tool for practicing repair skills, diagnostics and even designing automotive systems. But if with virtual Satsuma or Ferndale everything is more or less clear, the transfer of game mechanics to real Russian cars raises a lot of questions. Is it possible to adapt the MSC logic for Lada Vesta, UAZ Patriot or GAZelle Next? Spoiler: yes, but with reservations.

In this article we will analyze three key aspects:

  1. What equipment will be needed to integrate game mechanics into a real car (and how much will it cost).
  2. How to transfer logic May Summer Car to domestic models without the risk of damaging the car.
  3. Legal nuances: what is allowed, and for what you can get a fine or lose your rights.

It is important to understand: we are not talking about “implanting a game into a car” (this is technically impossible), but about reproduction of game principles - for example, installing sensors to monitor the condition of nodes, as in MSC, or creating a system of “repair quests” for training. If you expect that after reading this you will be able to drive on real roads with the interface from the game - close the tab right now.

1. Which Russian cars are suitable for the "May Summer Car" project

Not every domestic car is suitable for experiments. Main selection criteria:

  • 🔧 Simplicity of design. Models with minimal electronics are ideal: Lada 2107, UAZ "Loaf", GAZ-3110. The fewer “brains” (ECU, CAN buses), the easier it is to implement custom sensors.
  • 🔌 Availability of spare parts. In MSC, the key mechanics are breakdowns and their elimination. If it is difficult to find parts for your car (for example, ZAZ Tavria), the project will lose its meaning.
  • 📡 Possibility of connecting external devices. We need free connectors for sensors (for example, OBD-II on Lada Granta or Vesta).
  • 💰 Budgeting. If a car costs more than 500 thousand rubles, it is unwise to take risks. The best option is a used car up to 200 thousand.

Here's what doesn't fit:

  • ❌ Modern Lada Vesta or XRAY with complex electronics (risk of ECU blocking).
  • ❌ Cars with diesel engines (for example, UAZ Profi) - the fuel system is too specific.
  • ❌ Auto with hybrid or electric powertrains (for example, Lada Largus hybrid in test batches).

Lifehack: if you want to start small, take Lada 2106 or Moskvich-412. Their electrical circuits are simpler than those of modern cars, and spare parts are cheaper. For example, a temperature sensor for a “six” costs 200 rubles, while for Vesta - from 1,500.

📊 Which Russian car would you choose for the May Summer Car project?
Lada 2107
UAZ Bukhanka
GAZ-3110
Lada Granta (until 2018)
Another (I’ll write in the comments)

2. Equipment for integration: what to buy and how much it costs

To reproduce the mechanics May Summer Car on a real machine, you will need:

Component Purpose Approximate price (2026) Where to buy
Arduino Mega 2560 Main controller for collecting data from sensors 2 500 — 3 500 ₽ Aliexpress, Chip and Dip
CAN bus adapter (ELM327) Reading data from the on-board computer (if OBD-II is available) 800 — 1 500 ₽ Yandex Market, Beru
Temperature sensors (DS18B20) Monitoring overheating of engine, gearbox, brakes 150 - 300 ₽/piece. Aliexpress, local radio stores
Relays and transistors Control of external devices (for example, simulation of breakdowns) 50 - 200 ₽/pack. Any electronics store
3D printer (optional) Printing mounts for sensors and control panel 20 000 — 50 000 ₽ SberMegaMarket, local workshops

Minimum budget to start - about 10,000 rubles (without 3D printer). If you want a full-fledged system with data output to the screen (like in a game), add more:

  • 📺 Display 7-10 inches (3 000 — 8 000 ₽).
  • 🔋 Uninterruptible power supply (2,000 - 5,000 ₽) so that the sensors work when the ignition is turned off.
  • 🔧 Set of terminals and wires (1 000 — 2 000 ₽).

Critical detail: If your car is older than 2000, it most likely does not have OBD-II. In this case, you will have to solder the sensors directly to the wires (for example, to the coolant temperature sensor). This requires auto electrician knowledge!

⚠️ Attention: Do not buy cheap Chinese Arduinos - 500 rubles each. They often work unstable with analog sensors, which will lead to false alarms (for example, it will show engine overheating at normal temperature).

Check Arduino compatibility with your machine (on the forums)

Buy spare fuses (in case of short circuit when connecting)

Download the wiring diagrams for your model (for example, on Drive2)

Prepare a soldering iron and heat shrink to insulate the connections -->

3. Step-by-step instructions: how to connect sensors to a Russian car

Let's look at the process using an example Lada 2107 (carburetor). For injection models (for example, Lada Priora) additional configuration of the CAN bus will be required.

Step 1: Connecting the Arduino to the Onboard Network

1. Find in the car safety block (usually under the torpedo on the left).

2. Connect plus Arduino to ignition (IGN) (so that the device only works when the ignition is on).

3. Minus place it on the body (any bolt with clean threads).

Step 2: Installing Sensors

Start with critical nodes:

  • 🔥 Engine temperature sensor: screw to the cylinder head (next to the standard sensor). Use thermal paste for accuracy.
  • ⚡ Battery voltage sensor: Connect to the battery terminals via a 5A fuse.
  • 🛞 Oil pressure sensor: cut into the oil line (requires adapter with M14×1.5 thread).

Step 3: Setting up the program

Download ready sketch for Arduino (sample code below) and upload it via Arduino IDE. Adjust the trigger thresholds to suit your car (for example, engine temperature above 105°C = "critical overheating").

// Example code for temperature monitoring

#include 


#include 



#define ONE_WIRE_BUS 2 // Pin for DS18B20 sensor



OneWire oneWire(ONE_WIRE_BUS);


DallasTemperature sensors(&oneWire);



void setup {


Serial.begin(9600);


sensors.begin;


}



void loop {


sensors.requestTemperatures;


float temp = sensors.getTempCByIndex(0);



if (temp > 105) {


Serial.println("CRITICAL OVERHEAT! Engine temp:" + String(temp) +"C");


// Here you can add relay control (for example, turn on a fan)


}


delay(1000);


}

Important: Before the first start, check all connections with a multimeter. A short circuit can damage both the Arduino and the on-board electronics of the machine.

1) Correct connection (plus/minus).

2) Tightness of the connection with the oil line (oil leaks are unacceptable!).

3) Sensor calibration (maybe you need offset in the code).-->

In Russia, any changes in the design of a car are regulated Technical Regulations of the Customs Union 018/2011. Here's what the law says:

  • ✅ Allowed:
    • Installation of additional sensors (if they do not affect standard systems).
    • Connection of external screens (provided that they do not block the driver’s view).
    • Modernization of lighting (for example, LED lamps in headlights, if certified).
  • ❌ Prohibited:
    • Interference with work ABS, ESP, airbags.
    • Changing the design of the brake system or steering.
    • Installation of devices that simulate malfunctions (for example, forced switching off of headlights).

If you plan to participate in road traffic, after installing the equipment you must:

  1. Pass technical expertise in an accredited laboratory (cost: 5,000 - 15,000 rubles).
  2. Get design safety certificate.
  3. Re-register changes with the traffic police (fee: 800 ₽).
⚠️ Attention: If a traffic police inspector discovers uncertified changes (for example, a homemade control panel on the steering wheel), you will face a fine Part 1 Art. 12.5 Code of Administrative Offenses of the Russian Federation - 500 rubles. But if the changes affect safety (for example, ABS is disabled), the penalty is increased to deprivation of rights for 6–12 months.

Workaround: if you don’t want problems with the law, use the system only in closed areas (for example, in a country house or in a garage). You don't need any permissions for this.

💡

Any changes in the design of the car that affect safety must be agreed with the traffic police. Sensors and screens that do not affect standard systems usually do not require legalization, but it is better to check with your local MREO.

5. Practical quests: how to make a “game” out of a car

Main difference May Summer Car from a regular simulator - quest system. You can reproduce it in real life. Examples:

  • 🔧 "Fixing the generator":
    • Program the Arduino to randomly "turn off" the generator (via a relay).
    • The player's task: find the malfunction (check with a multimeter, replace the fuse).
  • 🚗 "Evacuation in tow":
    • Simulate a gearbox failure (for example, by blocking the transmission through a solenoid).
    • The player must properly attach the cable and tow the car without the risk of damage.
  • ⛽ "Refueling in the field":
    • Hide a can of gasoline 500 meters from the car.
    • Task: drain gasoline from the tank, go to the canister and return (as in MSC).

To automate quests use:

  • Voice prompts via a Bluetooth speaker (for example, “The engine is overheating! Check the antifreeze level”).
  • Light signaling (flashing LEDs on the panel for critical errors).
  • Mobile application (for example, on Blynk) to manage quests remotely.

Example of the quest "Point A - Point B" (as in MSC):

  1. Fill the tank with exactly 10 liters of gasoline (enough for 80 km).
  2. Program the Arduino to show "fuel leakage" (0.5 l/hour).
  3. The player must get to the goal, taking into account the loss of gasoline, and find “spare parts” (parts you have hidden) along the way.
How to make a quest more difficult?

Add "random events":

- Wheel puncture (simulated by deflating the tire through the nipple).

- Starter failure (blocking via relay).

- Lost key (hide the duplicate 100 meters from the car).

Use a random number generator in Arduino for unpredictability.

6. Common mistakes and how to avoid them

Even experienced car enthusiasts make mistakes when adapting May Summer Car. Here are the top 5 mistakes:

  1. On-board network overload:

    Arduino + sensors + screen can consume up to 5A. If you connect everything to the cigarette lighter, it will melt. Solution: Run a separate line from the battery through a 10A fuse.

  2. Incorrect sensor calibration:

    If the oil pressure sensor shows 0 when the engine is running, check:

    • Correct connection (+5V, GND, Signal).
    • Match the sensor range (e.g. 0–10 bar for Frets).
  • Ignoring weather conditions:

    Temperature sensors may fail in cold weather (-20°C). Solution: Use extended range models (e.g. DS18B20 works down to -55°C).

    • The most dangerous mistake - attempt to imitate brake failure. In the game this is fun, in reality it is a criminal liability (Article 268 of the Criminal Code of the Russian Federation, “Violation of traffic safety rules”). Instead, train in closed areas with an instructor.

    ⚠️ Attention: If you are using GAZ-66 or other vehicle with air brakes, never block the compressed air line. This may lead to uncontrolled movement of the machine even on a flat surface!

    7. Alternatives: what to do if you don’t have time for Arduino

    Not everyone wants to solder circuits and write code. Here are ready-made solutions for imitation May Summer Car:

    • 📱 Mobile applications:
      • Torque Pro (Android) - shows engine parameters via OBD-II (analogue of sensors from MSC).
      • Car Scanner ELM — diagnostics of faults with decoding of error codes.
    • 🎮 Ready-made simulators:
      • BeamNG.drive — damage physics is close to MSC, there are mods with Russian cars.
      • Automobile Simulator — emphasis on repair and diagnostics.
    • 🔧 Education Kits:
      • Buy a used engine (for example, from VAZ-2108) and practice on it in the garage.
      • Use simulators for auto electricians (sold on Avito for 10,000 - 20,000 ₽).

    If the goal is repair training, not a game, pay attention to the courses:

    • Driving school "Master" (Moscow) - practice on real machines with simulated breakdowns.
    • Heidelberg Engineering (online) - courses on auto electronics with an emphasis on diagnostics.

    FAQ: Answers to frequently asked questions

    Is it possible to install May Summer Car on Lada Vesta 2020?

    Technically yes, but with caveats:

    • Vesta has a complex CAN bus, so connecting sensors will require protocol reverse engineering (or using ready-made solutions like OpenPort 2.0).
    • Any changes to the electronics may result in ECU lock (firmware for a specific machine is required).
    • Legally: if changes affect standard systems (for example, connection to the instrument panel), approval from the traffic police will be required.
    Recommendation: Start with a simpler machine (eg. Lada Kalina first generation).
    How much does a complete set of equipment for the project cost?

    Calculations for 2026:

    Option Cost What's included
    Minimum 8 000 — 12 000 ₽ Arduino, 3 sensors, wires, fuses
    Medium 25 000 — 40 000 ₽ Arduino + CAN adapter + screen + 5 sensors + 3D printed mounts
    Maximum 70 000 ₽+ Complete set with servos (simulation of breakdowns), GPS tracker and mobile application

    Advice: Buy equipment in stages. First, test the Arduino with one sensor, then buy the rest.

    Can this project be used to teach teenagers how to repair cars?

    Yes, but subject to safety rules:

    • 👍 Allowed:
      • Studying the engine structure on a removed unit.
      • Diagnostic training using an OBD-II scanner.
      • Simulation of simple breakdowns (for example, replacing a fuse).
    • 👎 Prohibited:
      • Working with the fuel system (risk of fire).
      • Any manipulation of the brakes or steering.
      • Using a real car in motion without adult supervision.

    Alternative: buy a disassembled engine mockup (for example, VAZ-2108 on AliExpress for 5,000 ₽) and train on it.

    How can I make the sensors work when the ignition is off?

    There are three options:

    1. Connection to battery via relay:
      • Plus is taken directly from the battery.
      • Minus - on the body.
      • A relay is added that breaks the circuit during prolonged inactivity (so as not to drain the battery).
    2. Using a UPS (Uninterruptible Power Supply):
      • Suitable for Arduino+ screen.
      • Operating time: 2–4 hours (depending on capacity).
  • Solar panel:
    • Connects to the battery via a charge controller.
    • Suitable for long-term monitoring (for example, in the country).
    ⚠️ Attention: If you leave the Arduino connected to the battery for a week, the battery will drain to zero. Use voltage control module, which will turn off the power at 11.5V.
    • Where can I legally test a car with custom systems?

    In Russia there are several options:

    • Autodromes:
      • Examples: Myachkovo (Moscow region), Kazan-Ring.
      • Rental cost: 2,000 - 5,000 RUR/hour.
    • Closed industrial zones:
      • Negotiate with the owners of abandoned factories or warehouses.
      • Typically, rent is cheaper than at a race track (1,000 - 3,000 rubles/day).
    • Private areas:
      • Fields, forest roads (with the permission of the owner or local administration).
      • Be sure to tape off the area and put up warning signs.

    Important: Even in closed areas, follow traffic rules. If an accident occurs (for example, you hit a pole), the insurance company will not pay compensation.
