Wow that came out miraculously well. Nice job.

Nice job! But maybe you will have the same problem as I do, you can't properly open the false floor now, because it could get stuck against the bracing.
Only a problem if you often want to access the tools below or store some stuff between there.
But I will have to make bigger cutouts sometime because it's little bit annoying.

Yeah it's a good point - I accounted for this enough with mine to mean I can lift the floor up enough to get the tray out without having to remove the floor, but you can't tip it all the way up to the trunk lid. Good point though to remember this when doing your cutouts.

Does this help in the meantime? https://cad.onshape.com/documents/40...f5b6a01462b639

I might need to borrow this…

After a bit of a prolonged shambles the second USBJTAG uLink NT FINALLY arrived yesterday, so this afternoon after work I put together an adapter cable and BDM'd the DME to recover it. Aside from Microsoft causing me grief all was straightforward and I can now connect to the DME with INPA. I restored to the base CSL program and tune so tomorrow morning I'll flash my latest program and tune files and get up and running.

Why did this take so long?

I ordered the first uLink NT from USBJTAG at the beginning of November. about two weeks later I stopped seeing any updates on tracking. I chased them up (6 weeks after ordering) and was told to be patient, chased them again (10 weeks after ordering) asking for a resolution and they simply never replied. I generally don't like doubling down on a poor experience but in this case didn't have too many alternative options so I ordered a second one which thankfully made it here. I still have had no resolution from them regarding the first one that went missing in transit.

The device and software is great, very easy to use and now that I have it I'm very happy with it, but I do advise caution/realism around the shipping side of things. Hopefully mine is an outlier experience in this regard and others don't encounter it as this is a very simple and clean solution for those of us with ST eeproms.

With my DME recovered I was able to finally finish off the last little bit of something I've been working on for a while: MSS54HP CSL 0401 Community Patch Binaries

These binaries wrap up a bunch of QoL improvements into a single package. I was very close to having this done when I messed up a memory reference and that's what bricked my DME. With my DME recovered I've been able to complete testing on this, very pleased to have this done and out there.

As noted in the post I need to swap over to the CSL boot loader and test that version before I make it available. I'm extremely confident it is correct as it's the exact same as the version for the 2300 boot loader minus the additional changes needed to get the 2300 boot loader working, but unless someone volunteers to test it it'll need to wait until I get a chance.

Thats awesome! Thank you for doing that mate.

Spent the last week in bed with Covid, and only just re-emerging now.

Directly before I went down I completed building out the generalised configurable CAN message functionality for inclusion in the next version of Community Patch. This functionality is an extension of the custom program ROM I've been running for the last few months.

• Up to 3 configurable CAN messages for a total of 24 bytes of variables of your choice at 100hz.
• Ability to push up to 16 bytes of Slave-processor-only variables to the DPR (shared RAM) to make them available to then expose in the configurable CAN messages. This is something new I've been working on and means there's now no restriction on what variables can be exposed to CAN, if it exists in the DME you can push it on the CAN bus.
• Configuration validation on DME startup for both CAN message config and Slave-to-DPR config.
• New functionality off by default, must be configured to enable it (means backward compatibility with any 0401 Tune file)

If I get a chance this weekend I plan to flash the program and test it out. I'll then need to flash a bunch of different tune files to validate the various combinations of config validation, etc.

This feature is only fully useful to others when available alongside a list of DME variables. Obviously we don't know all of these, but I'm intending to extract a list from the disassembly, along with descriptions where we have them, that people can refer to. With that and some decent instructions it should be a fairly useful feature.

Glad you are feeling better!
