Chiptuning - Benefits, and why has not the manufacturer already done it?

Since the beginning of the automobile history, modifications on the engine has been done. Even on Henry Ford's model A the driver was able to control the ignition with a ruler on the steering column. The goal was to improve the performance of the engine, by adjusting the optimal ignition timing, and the best possible Fuel to Air ratio. Many days have went by and the technology of the engines has improved dramatically during the last 20 years. Electronic injection systems, direct injection, and electronic ignition systems enables to gain respectable power out of 'small' engines, engineers would have dreamed of some years ago. Today, all the engine settings are controlled and regulated by the ECU (Engine Control Unit). The software in the ECU control Fe. the ignition timing, fuel supply, turbo-boost, etc. to get the best possible performance. And that's exactly the problem. The manufacturer has to compromise many facts. The reasons for this are:

  • differences in the fuel quality in different countries
  • exhaust emission by using bad fuel
  • overdrafts of service-intervals
  • different driver-profiles
  • weather-factor (extreme heat and frostiness)
  • country-specific exhaust values
  • financial reasons like insurance-grades

So the manufacturer needs to be content with a compromise-solution to ally all these facts. There are also big fabrication tolerances, which the manufacturer wants to avoid by restricting the ECU software. The result is a pretty weak and conservative software for your car's ECU. Our task is to eliminate this compromises. We optimize and individualize the software of your car in a way, which leaves reserves for tolerances, but not with the intensity of the manufacturer. The software is individually developed for your country (petrol quality, emission... ) to keep the car/engine within all these tolerances.

Will the lifetime of my engine be affected in a bad way after the optimization?

The simple answer is: No!

The power reserves of the engine are so large, that you don't have to expect more engine wear. We optimize the settings of the engine without exceeding the limits of the reliability. If the car is driven normally there are no decreases of the lifetime! If the car is driven very hard (racing situation), the approx. reduced lifetime is about 3-5 %. That would mean Fe. 480.000 km (300.000 miles) instead of 500.000 km (312.000 miles).

 

What about gas consumption?

Depends on the driving style. The optimal adjustment and the increased torque normally causes reduction of fuel consumption up to 10 %.

 

Is ECU-Tuning detectable during the inspection?

No. Your car dealer can not determine a software modification with his equipment (diagnostic port), since the stock program is used to develop the upgrade, all engine characteristics are original.

 

Do I need a stronger suspension or brakes?

No, you don't need an other suspension or brakes after the optimization.

Will the engine operate at higher temperatures after the optimization?

The temperature can rise a very small amount (racing conditions). In average, this are between 5-8 degrees.
