Hello!
I have a issue regarding communication/connection with my SQ6 ECU.

It was bought already 2012 but has been lain in the box and not used, until now. I have build an engine wiring loom and a Ethernet wiring connection, but I can not connect to the ecu with PI Caltool or DescPro. The Ethernet connection seems to work. The computer says connected and the green and yellow led indicators on the Ethernet port blinks when the ignition is turned on, but DescPro and Caltool says no device. I have also tried to ping the ECU but it fails. The ecu puts out 5volts on pin 65 to the sensors so it has current and seems to be "alive".
Can it be the internal battery that is out of power? Do you have any other test I can do to be certain?

The ecu came with a disc with DESCPro 01P-099063 Pectel ECU Software Batch 147274. And I can pm you the serial number on the ecu.

I would prefer to use Caltool instead of DESCPro. Can the ecu be updated to the latest sw/firmware so I can run the latest Caltool version?

Hope you can help me and let me know if you need any further information from me!

Best Regards Johan

Hi Johan,
I´m not cosworth support but let me learn you what I do in case I have comm. problem with SQ6.

When the ECU is new and never was used, make sure you load proper code and dataset to it. Use programming loom (bench) to load the first basic map to start the car. Also make sure you don´t connect any sensors, devices to I/O pins until the base map is loaded (with proper pin-out config).

If this all is done I have to set manual IP address to my Ethernet adapter to 172.16.255.130 , I leave the mask at 255.255.0.0

Then I keep Caltool with dataset open while in detection disabled mode.
I start OFFloadtool, wait till sync with ECU. Sometimes it takes loger than a few seconds.
When it´s synced, then I turn the detection in Caltool ON (F11 key)...

This always work for me...

I don´t use Deskprow.

Let me know if you get stuck.

Regards, Harry.

HI
Try disable firewalll sometimes not let you connect because of this.
Also you can try to connect via serial connection bit slower but firewall wont affect communication

Hi!

Thanks for the answers!

Finally I got my SQ6 ECU back. It was the internal battery that was out of power and therefore the Ethernet connection did not work. So now the ecu has a new battery and I managed to get online.

The ecu has also been updated to the latest turbo sw but unfortunately I did not get the corresponding metafile from my tuner.

Is there any place there I can download the metafile for the latest turbo sw for SQ6 from? Do I need anymore files? Or can you send me the file?

Thanks in advance!

Best Regards Johan

Hi JohanT,

You can also sent an email to us to get the right metafile.

If the internal ECU's battery is out, will the car run,
and if it does run will it have problems or does it
only affect Ethernet connectability?

Thanks ahead of time for an answer. [smile]

Hi Reggie,

I am presuming that you are referring to a flat battery as opposed to the battery being "out" Generally if the ECU internal battery is flat the car will still run and the ethernet connection is fine. If the battery is flat you would normally only lose the logging configuration and logged data. If you are having these sort of issues then please make a separate post about this subject and we can continue the conversation from there as this sound different to the original post.

Many thanks,

Rob
