Do you publicly release firmware updates for the SQ6 range of ECU's? Or is it something you deal with on a per-customer basis?

We used the SQ6 and SQ6M at my last job, but they were all running pretty old (like 5+ years) firmware versions. One of the things I wanted to do before I left was get them going on a more recent version, as apparently some CAN profile bugs I was encountering had been ironed out.

Would still be keen to get it sorted if possible, might make any support they need in the future easier too?

Hi ZacMan,

Typically we deal with this on a per customer basis as depending on what you're going to and from, and also what the project is there can be quite a lot of changes and these that must be adjusted and checked before the dataset can be sent to the ECU.

Also depending on the users ability we generally recommend a version based on their application.

The SQ6(M) Release Notes document can be found here:

Have a read through them and if there is a version you would like to use then get in touch with me and we can make the arrangements.

Many thanks,
