The CarTuner is attached to the positive terminal of the car battery with the hook-and-loop strip supplied – and with that the whole vehicle is covered. No tools, no garage.
How it works
The CarTuner creates a harmonious vibrational field within the vehicle’s energy system. In this field, artificial frequencies can no longer produce resonance, and cell functions are therefore no longer irritated. The energy the body previously had to spend on compensating is released. It usually uses that energy to restore its homeostasis. Where, how and whether this becomes noticeable differs from person to person and cannot be predicted.
We do not shield anything and we do not fight anything. The CarTuner works on the level of information: what it does is not directly measurable and can be observed only indirectly, through changes people perceive. The effect is stable and does not diminish, regardless of the strength of the electromagnetic exposure.
A modern car contains several kilometres of cable, and in a luxury-class vehicle thirty motors and servos and more are at work. This is precisely the environment the CarTuner is made for.
The CarTuner in an electric car
The CarTuner is intended for every vehicle — combustion engine and electric car alike. The type of drive changes nothing about the principle: the CarTuner does not shield, it creates a harmonious vibrational field within the vehicle’s energy system. In this field, artificial frequencies no longer produce resonance.
The way it is attached is the same as well: with the hook-and-loop strip supplied, to the positive terminal of the auxiliary battery, which an electric car has too – there it supplies the entire vehicle electronics. Nothing is attached to the traction battery.
What customers report
In our experience, and according to the feedback of many customers, electrosmog is no longer perceived as a burden in such an environment, regardless of the frequency range the mobile network transmits in.
As for consumption, customers report 10 to 20 per cent less fuel since they installed the CarTuner. That is their experience, not our promise: it differs from person to person and cannot be predicted.
Further reading: two studies on consumption
There are two documented studies on the CarTuner. They concern consumption and exhaust emissions, not health.
Emissions Analytics, 2015. Mobile exhaust measurement technology on a single, EU type-approved passenger car. Measured by Emissions Analytics Ltd. at the Bruntingthorpe Proving Ground in Leicestershire, England, on 23 and 24 November 2015; report by Nick Molden dated 11 December 2015. A composite cycle of urban, rural and motorway sections was driven, repeated several times, once before and once after the CarTuner was fitted, under conditions of weather kept as similar as possible. Across the whole cycle, each result statistically significant: fuel efficiency 3.9 % better, carbon dioxide 3.7 % lower, carbon monoxide 36 % lower, nitrogen oxides 9.0 % lower. Individual driving profiles came out more markedly – in urban traffic up to 4.6 % better fuel efficiency and 4.4 % less carbon dioxide, on rural roads up to 40 % less carbon monoxide and 13 % fewer nitrogen oxides. Nitrogen dioxide fell by 2.4 %; that figure was not statistically significant. The measurements were taken on one vehicle, and the report itself states that further measurements would be needed for general statements about the vehicle fleet. View the full report.
Test drive London–Edinburgh. Our own documented drive, filmed in full: the same route twice, once without and once with the CarTuner. On the outward journey, 5.3 against 4.1 litres of diesel per 100 kilometres. Accompanied by J-motion, a professional video producer; the video is at the top of this page. One vehicle, one route – a single case.
Neither of these two studies proves an effect on health, and neither says anything about the level of information.
An expert report by the Institut für Resonanzphänomene describes how the CarTuner works: read it here (in German).

Peter S., Rothenburg (CH)
I already have the following products from you:
– BioRing (I am more balanced; clear difference to the temporary heraldic ring)
– Deep sleep band (I can fall asleep and stay asleep quickly)
– CarTuner (no more microsleep, less diesel consumption)
I am therefore very satisfied with your products.
Update from 07.11.2022 – Delivered by the customer.
My current status, which I no longer want to do without:
– Air conditioning tuner (I installed it myself for the whole apartment according to your instructions).
– Car Tuner (unchanged, and also successfully in use after changing the car to a gasoline hybrid).
– Bio Patches (for mobile phone and cordless phone),
– Body Card (for on the go, always with you).
– I no longer need the Bio Ring and deep sleep band !!!
Your products are wonderful!
I am simply doing very well! Thank you very much.

Dear Mr. Neubersch, I would like to thank you personally VERY Sincerely.
They are an invaluable help to me with all their products.
The CarTuner is also simply brilliant!

Since installing the CarTuner, the engine in our car runs much more quietly and it is more pleasant to drive. The bangles helped us a lot during the moving phase.

This morning I installed the CarTuner in my car before driving to Baden Baden. After 50 km I got onto the highway behind Freiburg. The car ran more and more smoothly, and at full throttle not 160 but a good 180. I ended up saving 5 euros over 350 km.

My wife often had pressure on her “cell phone ear” in the evening, and I also had slight tinitus …
Now, with the BioPatch on the smartphone, it’s gone.
My fuel consumption has dropped by 2 liters at a constant 120 km/h with the CarTuner.
Great products ?

Yesterday I took the car to Vilters near Sargans to visit our daughter, about 200 km there and back. As much as possible with cruise control. Consumption so far approx. 4.8 to 4.9 liters/100km. yesterday 4.7 liters/100km. Cause of the reduction: The displacement of the device on the car battery by you, in the area of the positive pole! I’m curious to see how this will affect the summer tires.

I wasn’t allowed to drive faster than 140 km/h in the past, because otherwise my wife would immediately slow me down. Since I installed the CarTuner, it still looks calmly out of the side window even at 190 km/h. She says she is totally relaxed and no longer has headaches. Wonderful!

Thank you for sending the CarTuner to France so quickly! I had a long drive to Toulouse yesterday and felt a clear difference. I didn’t fall asleep during the whole journey (as a passenger) and even on the return journey, for which I was at the wheel myself, I felt much more awake and alert than usual. And the big “blind test” was my father, who regularly falls asleep in the car after 10 minutes and had no idea that we now have the CarTuner. He felt tired when he boarded and fell asleep briefly, only to wake up after a short time and stay awake for the rest of the journey.

The tests have proven that there is an improvement with the car tuner. Less gas consumption of about 10 to 15% and less gaz emission of about 15 to 20%.
Translation: The tests have shown an improvement with the CarTuner. Lower fuel consumption of between 10% and 15% and lower pollutant emissions of 15% to 20%.

I am absolutely delighted with the Cartuner. I drive a much more relaxed car and also have the impression that I need less diesel. We also slept in the car on vacation and the only thing that bothered us were the mosquitoes.

The CarTuner is the best thing I have bought recently. My children no longer get sick in the car and, above all, they no longer fight in the back seat. That was always very annoying. But what I like best is that my tank lasts longer. That’s very good for my household budget!

Klaus T., Zurich (CH)
Dear Mr. Neubersch, could it be that the CarTuner also has an effect on static charging? In any case, I no longer get an electric shock when I touch my car. And the best thing is that my fuel consumption has dropped from 9.6 l to 7.5 l. I would never have thought that possible. I only ordered your product because I wanted to do something about the electrosmog in my car, because my wife has always suffered a lot from it. But even that is over now. Thank you very much!

Beat S., Brienz (CH)
Dear Richard, as you know, I often fell asleep for seconds in the car, even if I only had short journeys and was fully rested. When you told me that this had to do with electrosmog, I didn’t believe you. Actually, I only let you install the CarTuner because you were so convinced and I thought I would soon be able to give it back to you because it wasn’t working. But I was wrong, because since I’ve had it, it’s never happened again, no matter how long my journeys are. So thank you from the bottom of my heart and especially for the fact that I have less gasoline costs. I estimate it’s a good 10 to 15%.
