The Commander660 ECU is the new version replacing the Commander66 ECU (which is no more manufactured).
It owns a twice as much memory size which allows supplementary calculations, larger maps, and an improved security of the CAN-Bus transmissions.

It is possible under some conditions to convert by Skynam your Commander66 into Commander660. No installation modification on the engine is required.
Contact Skynam.



Here is the simple and secure method of update of your ECU with a new software version, which also allows to pass a Commander66 tuning to a Commander660.

Securization of the wheels speed measurement:
• In the previous versions, when the wheels speeds were slow, a speed measurement error could happen which was causing a brief dysfunction of the anti skating.
• This version prevents from the speed measurement error.

Securization of the engine synchronization with a camshaft target with one supplementary tooth:
• In the previous versions, When the phase sensor was reading a camshaft target with one supplementary tooth, the engine synchronization could fail with an engine start not done.
  A second try of engine start was then necessary.
• This version ensures a perfect synchronization of the engine even in these conditions.

Improvement of the fuel high pressure control on direct injection engines:
The new possibilities of tuning of the high pressure fuel pump in direct injection allow a very improved control of the fuel pressure.

Adding of a variable displaying the status of the engine synchronization:
This variable gives in real time the engine synchronization and can be recorded with the Winjal scopes to visualize possible problems of synchronization lost causing engine misfires.



Commander660 Tunewares:
• System V110
• Throttle/RPM: V110 (new - 7th 12/2017)
• Pressure/RPM and turbo: V110 (new - 7th 12/2017)

Documentations in English:
• Commander660 tuning software pack: 37 separate documents, each for one specific fonction of the ECU, with many didactic examples (new - 7th 12/2017)
• Commander660 installation: V1.00 - with commands of ignition modules (27th 11/2016)
• Commander660 options installation: V1.00 - sequential gearboxes, fly by wire, air electrovalves, bang-bang, ... (27th 11/2016)

• Does not contain Winjall software. Winjall must first be downloaded and installed apart.
• Does not contain the sensors convertion maps nor the actuators command maps. These maps have to be downloaded and installed apart with the pack SensAct.



No necessity.


Button to launch the downloads


NEEDING Winjall V9.1.0.0 (see specific downloading)

V9.1.0.0 or later version of Winjall software must mandatory have been installed first.



• Download new .zip Commander660 software pack file and save it in a directory on your hard disk.
• If you have already install a former version of this pack, you have to usinstall it before installing this new one:
In Windows XP, execute 'Start/Parameters/Configuration/Add-Remove programs'.
In Windows 7 and latter versions, execute 'Start/Parameters/Configuration/Programs and features'.
In the software list, select Commander660 then 'Uninstall'. Follow uninstall instructions.
• With the explorer, double click on the downloaded software pack .zip file, then double click on Setup. At the question on files extraction, answer 'Extract All'.
• If the installation does not automatically start: in the new directory created by the extraction, double click on Setup (application).




(Improvements are added from a version to the next one)


Throttle/RPM : V100 (System V100)
Pressure/RPM : V100 (System V100)

Version 100 is the base version of the new Commander660, Skynam high end ECUs.

This first version of the Commander440 software is based on the version of the Commander44 to which have been added some functions:
1) Test function of the injection and ignition commands without running the engine:
This allows to easily test the installation or the operation of the system.
2) Flywheel with several singularities:
This allows to easily install the ECU on many new engines without mechanical modification needs.
3) Measurement of the exhaust temperature:
• This allows to visualize and memorize the engine tuning quality and security.
• For turbocharged engines, the bang-bang can be cutoff in case of exceeding the critical temperature generating damages to the engine and/or the turbomachine.
