Go to Library

Online tool enables you to share and back up automotive waveforms. Convenient search options let you quickly find signal identical to the one you are working on. Any automotive scope user from around the world is able to upload waveforms in a global database. Join the community of professional diagnosticians and help us improve the project.

The latest updates are at the top. We recommend you start with the below posts in this article if you are beginner. We will publish a list of updates here with new functionality.

Frequently asked questions

How reliable are oscillograms from the library? Are they properly recorded?

Almost all oscillograms are copyrighted, some of the oscillograms have been uploaded by their authors, while others have been found in the public domain. We always give attribution to the author and primary source, so that you can fact-check. We can’t possibly ensure the validity of all publications, therefore we assume no responsibility for mistaken actions resulted from interpreting the information provided. If you spot a mistake, please let us know by mentioning it in the comment below the corresponding oscillogram or contact us directly to report a problem.

I’ve found my file in the library allegedly authored by another person. However, I haven’t authorized any publications.

As a rule, we always provide a link to the original source and the author. But sometimes it’s impossible to ascertain authorship. In this case, we offer these solutions:
  1. We edit the description and recognize you as the author. To make this happen, contact us in any convenient way (see the ‘Contacts’ section) and give us the link to the signal from the library and reference to the source where you first published the file. Or you may leave the message in the comments below the signal file.
  2. If you are against the publication, we assure you we’ll delete the signal from the library so that it’s not displayed in search results. 

I’d like to upload my files in the library. Do you guarantee you won’t be selling my files to other users?

All data found in our website is publically available and will always remain so. We have no intention of restricting access or monetizing the files. We can delete the files, if the author wishes so.

Quick templates for the most popular signal categories

To make it easier to add new signals to the waveform library and not waste time selecting categories, we have added the function of quick templates. The most popular waveform categories: CAM/CRANK, in-cylinder pressure, intake manifold pulsations, sensors connection points - now they can be selected with a single click. Then it remains only to choose the engine model and upload the recording file or screenshots.

Comments, search filters, icons, links

We added the ability to leave comments, added a link to the signal source, added useful icons, and changed the search filter working principle (Russian language only available, but we tried to make the interface as intuitive as possible).

New Waveform Uploading

We recommend you to watch the video tutorial before uploading new waveforms. It describes in detail the rules for oscillograms description, screenshots, and creating new categories. (Russian language only available, but we tried to make the interface as intuitive as possible).

You can send your waveforms to this email hello.rotkee@gmail.com. You have to specify the brand, model, production year, and engine code. Write which unit is connected to the scope channel. Add as much information as possible: describe the malfunction or indicate that the signal is known good. Attach the original waveform file, photos of sensors or probes connecting, troubleshooting codes, take scanner screenshots.

Waveform searching

A list of all available waveforms is displayed on the library’s main page in order from new to old. Up to 15 signals are displayed on the page; others are available on the next pages.

On the main page, the signal is displayed in a shortened form and has the following structure:

1. Screenshot of the program, which was used to capture the waveform.

2. Arrows for scrolling screenshots.

3. Diagnosed car detailed info.

4. Signal status: reference or known malfunction.

5. System to which the automotive scope is connected.

6. The signal's author.

7. Button to switch to the full version of the signal data.

A page with all the details of the signal will be displayed, when you click on the "In detail" button.

1. Name of the unit to which the scope is connected.

2. Note of the signal's author.

3. Link for the original zipped scope file downloading (it becomes available after you sign in), the size of the archive is shown in brackets.

4. The author's nickname.

5. The date the signal was added to the library.

6. Link to the source of the waveform or section with a discussion of this signal (it becomes available after signing in).

To reduce the list of displayed signals on the main page of the library, you have to apply the relevant filters. At the top left of the page are filters for selecting a car.

1. Carmaker brand.

2. The number of available waveforms for this item.

Automotive Waveform Library – the project updates

1. Model name.

2. An alternative name for other countries markets.

3. Generation.

4. Body code.

5. Production years of the model. Usually, the time range is shown when the production was started and when it was finished (not model years), for example, 2001-2007. If the model produced at the current time, the date ends with a dash: "2015-"

6. The number of available waveforms for this item.

Automotive Waveform Library – the project updates

1. Engine code.

2. Alternative code.

3. The valves amount.

4. Engine displacement.

Automotive Waveform Library – the project updates

At the top right side of the page are filters that show which car unit is connected to an automotive scope. The number of available signals for the selected system is also displayed in brackets.

The structure may seem a bit confusing, but in the future, we will make standard templates for the most popular waveform groups.

To get started, fill out the required fields; the more data you fill in, the more detailed search will be. We recommend watching a video before you start (Russian language only available, but we tried to make the interface as intuitive as possible).
