Is this worth considering leaving all bias to one side?
Is this effectively a remap, chip or electrickary?

Just plug and play they say.
Thanks

It is electrickery, and at that price you'd be far better off getting a BD or TRS ECU.

FWIW I'll be selling my BD ECU once I debrick the new one, probably with-in the next couple of weeks.

Here's my top tip for reflashing: Reformat the card and copy ONLY the .map file you will be uploading. It's worth a shed full of external power supplies.

I discovered today that if the .map has been loaded on a card that already has a bit of junk on it, the remap is almost 100% certain to fail. Same .map on a clean, reformatted card sails through without a hiccup.

And for the nervous, it's worth noting that a .map upload failure will only brick the ECU if it occurs after the "please wait" that happens with 10% remaining. I had a remap lock up at 50% and I had no problem restarting the process.

I have a Defender and I have found that if you follow the menu for a Defender and update the ECU .map file and it fails it will brick the ECU.

Using the Discovery menus it works as you have described. I imagined that the nannocom would use the same process for the disco and defender TD% remapping so I am not sure why I have had the issue with the defender option and not disco. Just so you know it is not a fluke I have repeated the same process at least twice.
