What is a 1 Car internship?
A Stage 1 Car is the first step in modifying a vehicle's performance. It mainly involves reprogramming the engine control unit (ECU) without adding any mechanical parts.
The aim is to optimize engine parameters to improve power and torque, while remaining within the tolerances of the original components .
Reprogramming the engine ECU allows you to modify parameters such as :
- Ignition timing
- Turbo boost pressure
- Fuel injection management
For example, for a Volkswagen Golf GTI, a Stage 1 can increase power from 230 hp to around 280 hp, and torque from 350 Nm to 450 Nm.
This translates into a significant improvement in performance without compromising engine reliability.
It's important to note that the Stage 1 Car requires no internal engine modifications, making it accessible and relatively affordable for performance enthusiasts.
Where can I do a 1-car internship?
To carry out a 1-Car Internship, it's essential to choose a qualified and experienced provider.
Check online reviews and automotive forums for recommendations on the best reprogramming centers.
Check whether the center offers a warranty on the reprogramming performed.
Reputable centers in France include ShifTech, BR-Performance and Digiservices, known for their expertise and convincing results.
For example, ShifTech offers Stage 1s for a wide range of vehicles with optimized power and torque gains.
How to do a Stage 1 on your own car?
Doing a Stage 1 on your car yourself can be an exciting and rewarding adventure. Here's a short tutorial.
Tools and software required
To carry out Stage 1 on your own, you'll need the following:
- A laptop computer with a stable Internet connection.
- An OBD-II cable to connect your computer to the car's ECU.
- ECU reprogramming software such as ECU TitaniumWinOLS, or Alientech KESSv2.
- Vehicle-specific mapping files, available on specialized forums or from companies such as Tuning Files.
Steps to Complete a 1-Car Internship
1. Identify your vehicle's specifications (make, model, year, engine).
2. Search tuning forums for tips and reliable mapping files.
3. Connect the OBD-II cable to the corresponding socket in your car (usually under the dashboard).
4. Use the reprogramming software to read the current ECU parameters and save the original file before making any changes.
5. Load the mapping file into the software and make the necessary modifications to optimize engine performance.
Common modifications: increase turbo pressure, adjust fuel injection times and modify ignition curves.
6. Once the changes have been made, use the software to write the new data to your car's ECU.
Make sure the operation is carried out without interruption to avoid damage to the ECU.
7. Start your car and carry out a test drive to check the improvements in power and responsiveness.
8. Use diagnostic tools to monitor engine parameters and adjust mapping if necessary.
Important precaution: Always save the original ECU file before making any changes.
How much does a 1-car course cost?
The cost of a 1-car course can vary considerably depending on several factors, including the type of vehicle, the complexity of the reprogramming, and the expertise of the professional carrying out the operation.
For a standard car like a Volkswagen Golf or Renault Mégane, the cost of a Stage 1 is usually between 400 and 800 euros.
For sporty models like the Audi S4, BMW M3 or Mercedes AMG, prices can range from 800 to 1,500 euros.
Prestige vehicles such as Porsches, Ferraris and Lamborghinis can cost up to 2,000 euros or more, due to the complexity of reprogramming and the precision required.
A 1-car course generally includes the following services:
- Initial diagnosis: Verification of current engine parameters to assess specific needs.
- ECU reprogramming: Modification of ECU parameters to optimize performance.
- Test and adjustment: Test drive and fine-tuning to ensure optimal engine performance.
How many horses can I win with Stage 1?
The power gain achieved by a 1-car stage varies according to a number of factors, including engine type, specific modifications and vehicle conditions.
1. Factors influencing Power Gain
Turbocharged engines generally benefit from higher power gains than naturally-aspirated engines.
A well-maintained engine will respond better to modifications.
Using optimized mapping files improves results.
2. Typical power gains
- Turbocharged petrol engines : Power gains for these engines can range from a further 20 to 30%. For example, a 200 hp 2.0 TFSI engine could reach 240 to 260 hp after Stage 1.
- Turbocharged Diesel engines : These engines can also see an increase of 20 to 30%. A 140 hp 2.0 TDI engine, for example, could increase to around 170 to 180 hp.
- Atmospheric engines: Gains are generally more modest, in the order of 5 to 10%. A 150 hp 2.0 L atmo' engine could gain an additional 7 to 15 hp.
3. Concrete examples
A Stage 1 on a Golf GTI (2.0 TSI, 245 original hp) can increase power to around 290-310 hp.
A Stage 1 reprogramming on a BMW 320d (2.0 diesel, 190 original hp) can increase power to around 220-230 hp.
For a Ford Fiesta ST (1.5 EcoBoost, 200 original hp), a Stage 1 can increase power to around 230-240 hp.
In some cases, a Stage 1 may also lead to a slight reduction in consumption.
How dangerous is a Stage 1 for your car?
Carrying out a 1-car training course involves potential risks that you need to be aware of in order to make an informed decision.
Increased turbo pressure can shorten turbocharger life.
Parts such as the clutch and gearbox sprockets can wear out more quickly under higher loads.
Reprogramming can increase the heat generated by the engine, putting more strain on the cooling system.
Modifying the ECU may invalidate the manufacturer's warranty, as the car is no longer in its original configuration.
Some insurance companies may refuse to cover a modified vehicle without prior declaration.
Premiums may increase as a result of the modification.
Incorrect reprogramming can lead to malfunctions, engine failure or serious damage.
Stage 1 on a diesel VS petrol car
Power gains
Turbocharged diesel engines, such as Volkswagen's 2.0 TDI, can see gains of 20 to 30% in power.
Torque, crucial for diesels, also increases significantly.
Turbocharged petrol engines, such as Audi's 2.0 TFSI, benefit from a similar gain in power.
Atmospheric engines see more modest gains, often between 5 and 10%.
Fuel consumption
Well-executed reprogramming can slightly improve fuel efficiency, especially at low engine speeds.
Petrol engines can also see a slight improvement in fuel consumption, although this depends very much on driving style after the modification.
Driving sensations
Reprogrammed diesel engines offer a noticeable increase in low-end torque, improving acceleration and city driving.
Petrol engines offer more dynamic driving and better response at high engine speeds, enhancing acceleration and sporty performance.

Risks: Major vehicle transformation requiring in-depth technical expertise, significant increase in maintenance and repair costs, potential reliability problems.
Precautions to take on your car before a course 1
Before carrying out a 1-car workshop, it's essential to take certain precautions to ensure that the modification goes smoothly and that the vehicle can withstand the increased performance.
- Check and, if necessary, replace the air, fuel and oil filters.
- Carry out a complete overhaul, including checking the engine, transmission, cooling system and brakes.
- Perform a full diagnostic with OBD-II diagnostic tools to detect any anomalies or potential problems.
- Consider installing performance components such as high-performance spark plugs, or an upgraded intercooler.
Is a stage 1 on your car legal or not?
Here's an overview of the situation in France.
Under the Highway Code, any modification affecting the vehicle's technical characteristics must be declared and approved.
The modification must be approved by a certified body (DREAL or UTAC) to be legal on public roads.
Driving an unapproved modified vehicle can result in fines and impoundment.
In the event of an accident, insurance may refuse to cover damage if modifications have not been declared and approved.
