Exactly how is IT done? And what are we doing?

Since the early 1990s, most engines have been controlled by an on-board computer, the Engine Control Unit or ECU, which among other functions, defines the ignition timing, fuel pressure and boost pressure for all given engine speeds and loads.

After extensive development and testing, we arrive at the optimised settings for your make and model of vehicle, ensuring that each SPP modified chip is as individual as the software inside your ECU, safely eliminating those ‘performance compromises'.

In most cases this remapped programme is installed electronically and remotely through the car's diagnostic port. There's no replacement chip, and we don't touch the ECU itself.

We only optimise the mapping of ECU.

* We always test your vehicle before handing it back for you to enjoy, just to make sure everything is operating as it should be.

 

What will Swiss Car Vision do for my car?

SCV has a unique range of tuning upgrades for most modern petrol engines (turbo and non-turbo) and turbo-diesels.

Our trained engineers work on a broad range of engines and we have technical experts for all leading makes of vehicles.

We've chosen to work across the spectrum of engines; doing so keeps SCV up-to-date with the latest developments from each manufacturer. Ultimately, our wide-ranging and unrivalled experience delivers the best solution for your car.

 

Every chip SCV optimisation will deliver:

• An engine that responds more eagerly to your right foot

• Smoother power delivery making town driving easier with fewer gear changes

• Improved acceleration for safer over-taking

 

  For non-turbo petrol cars

• Up to 10% more power

• Enhanced throttle response

 

  For turbocharged petrol cars

• Up to 30% more power

• Up to 35% more midrange torque

 *SPP carefully matches increases in turbo boost pressure with the remapped ignition timing and   fuel settings. It doesn't affect the reliability or life of the engine. We know – we multiple years experience in enhancing the performance of turbocharged engines.

 

For turbo-diesel cars

• Up to 35% more torque and more power

• Fuel economy improvements

 Here too, we deliver a smoother, enhanced drive by ensuring our remap matches the fuelling to the increases in boost pressure.

 

 

FAQ

 

What is ECU Tuning?

 Modern engines are controlled today with a "computer" (ECU).
All important data (parameters) as for example: injected fuel quantity, load pressure, ignition etc. are controlled and supervised by that unit. Specific software is responsible for the adherence to these parameters. This software was developed and programmed by the manufacturer.

ECU tuning is simple to understand as it is the process of optimising the current settings / mapping of your cars on engine. 

We’ve seen our share of customers who, after the installation of a supposedly great and inexpensive chip, are greatly disappointed with the results that can range from significantly increased consumption due to a poorly tuned engine to a distinct loss in performance.

Our ECU optimisation eliminates the risk of this happening.

Examining these chips on a regular basis, we see some of the most adventuresome engine configurations. We emphatically warn potential customers about the risks of unprofessional chip installation. Even supposed copies of original chips offer no guarantee of sound functioning!

 

What’s the process of the actual tuning?

Once we have your car, we will do a Dyno-Run first, to see what the accurate power output is and to check if everything is ok with the vehicle. After the Dyno-run the ‘map’ (software the car is running on) is downloaded from the ECU.

After that we send the downloaded settings to our ECU programmer which makes the adjustments of the map’s parameter according to your requirements. After 1-2 hours we have the updated file and we uploaded into the car’s ECU again.

Next step is a test drive with the car of minimum 50km to see if everything works fine. The entire tuning process takes approximately 3-4 hours

 

Is the life span of the engine affected?

The car tuning is adjusted in a way so that it does not exceed any of the car limits, and your car maintains its original lifetime

 

What about fuel consumption?

This depends on the driving style. The optimal adjustment and the increased torque normally cause reduction of fuel consumption up to 15 %.

 

Is the optimization removable again?

Yes, on customer's request a re-equipment is at any time possible.

 

Does the dealer/agent see an error during the car diagnosis?

No, your car dealer cannot determine a software modification with his equipment, since the stock program is used to develop the upgrade. All engine characteristics are original.

 

Does the ECU optimisation affect the service intervals?

No, the service interval remains the same as before the ECU optimization was done.

 

Must I modify the brakes or the chassis?

The performance optimizations are co-ordinated in such way by us, that no further changes are necessary.
