Chiptuning tools are the most important tools for a tuning company. When you are new in the world of chiptuning / remapping, it is not easy to make the right choice regarding the chip tuning tool you need to buy. There are many different chip tuning tool suppliers.

Which brands and chip-tuning tools are the best? We help you to make things clear. Today we compare CMD and Alientech.

Introduction of chip tuning tools suppliers

CMD Flash (Flashtec SA) and Alientech SRL are two of the largest and most professional chiptuning tools suppliers on the market today. Both companies have been around for many years and are originally from North Italy located within 150 kilometers from each other. Another competitor named Dimsport is also located in the north of Italy. It seems the Italians dominate the tuning scene. But which company is the best? Let’s see…

History of CMD Flash

Old website:
New website:

This company is now called Flashtec SA. The company has Italian roots but is now based in Switzerland. They have been in business for many years and CMD is one of the first to introduce a stable OBD protocol for Bosch EDC16. CMD has products like CMDFLASH OBD, CMDFlash – BDM, CMDFlash – Nexus, Boost ST10/C167, BOOT-MODE BOSCH MEDC17 TRICORE, MAP3D, My Personal Flasher and SpiderBOOT.


History of Alientech SRL


Since 1991 they have been working in the field of engine tuning and chiptuning (ECU tuning/remapping). Over the years they have released many products like ECM2001, KESS, Powergate, BDM pro, ECM Titanium, KESSv2, K-TAG and Powergate 3. Alientech is one of the first companies to develop stable protocols with recovery functions for other ECUs than those developed by Bosch or Siemens. They developed protocols for JTAG Nexus, JTAG Renesas, Mitsubishi bootloader, etc.

CMD Flashtec & Alientech – Customers come first

Both CMD Flashtec and Alientech have many customers and are very appreciated. This gives the companies stability essential for a long term partnership and reliability. Customers pay an annual fee which is also a way of commitment. That way the customers are guaranteed that the companies will develop new protocols.

ECU tuning and development of new read/write protocols

In the world of tuning / chiptuning / remapping it’s all about the ECU. For example, as soon as VAG brings out a new car/engine, the ECU is immediately taken out and many tests are done to try and successfully read/write/modify the software in the ECU and to create a stable read/write protocol for their customers.

Of course, every company has its own knowledge and network to research and develop. In reality, we see that both Alientech and CMD can do many the same ECUs. The time of releasing new protocols varies from 1 month to 4 years after the introduction of a new engine by a car brand. But if one chip tuning tools supplier has a protocol ready, in most cases the other would prepare it within a few weeks/months.

Technical support

In our personal experience, we know how customer support is important. We use the chiptuning tools from CMD and Alientech for 85% of our tuning. We have tuned over 10.000 ECUs with their tools and tested every protocol. The protocols are not in all cases perfect and a lot of mistakes can be made by the customer who uses the tools.

Both companies have reliable support if you are a professional tuner with enough experience. If you are a newbie, it is different. In this case, we advise you to ask for advice from your tuning files supplier. A good tuning file supplier does not only sell files, but they also write the tuning files themselves in the cars of their own customers for their companies, too. They use the tools on a daily basis on all kinds of cars and ECUs, so they can tell you how to avoid traps and give you all the tips and tricks to make the reading and writing successful in real-time.

Chiptuning by OBD or Boot?

Both Alientech and CMD have many read/write tools. We can divide them into 2 groups:

1. OBD read/write by diagnostic port (KESS v2, CMDFlash OBD)

cmd flash tuning


  • Easy to use
  • Takes less time to work on
  • Foolproof
  • Not many accessories needed


  • Not all ECUs are available. (most new ECUs are only done directly on the ECU)
  • If reading/writing is not successful for some reason, recovery is not always possible
  • Only partial data is read

2. Directly on ECU read/write (KTAG, CMDFlash BDM – Boot)

ktag tuning tool


  • The highest amount of protocols available. Old ECUs, new ECUs, future ECUs, special brands
  • Newer ECUs’ protocols finished earlier after the introduction of the ECU
  • Protocols are more stable, better recovery if needed
  • Most chips can be read: eprom, mpc, eeprom. (important in case of immo off, recovery, etc.)


  • More difficult to use; you have to take out the ECU of the car, open the case and use the manual to connect the ECU to the tool.
  • Not foolproof, user can make mistakes that can destroy the ECU
  • Connecting takes more time especially when testing on the dyno

Keep up with new chip tuning protocols, updates, revisions, bugfixes

Both companies use an annual subscription. At first glance, this seems like a waste of money but in reality, this is very useful and important. This makes it possible for the companies to develop new protocols for new ECUs. You will always be up to date with the newest protocols, newest checksum corrections and bugfixes. This is the main reason why clone chip tuning tools are not interesting. The market is constantly evolving. Updates of protocols are crucial.
