Let me try to explain in Laymans terms what he is trying to do. Hopefully I'll keep it simple...
TLDR; He wants to understand the software instructions of the map so that he can tweak to his own likings without "buying" a new map.
Software, any software you see, from your Windows, to your MAC, to the LandyZone website, to download software such as Winzip is "packaged" into instructions. These instructions are then loaded into your a computer's chip and thus the chip follows the given instructions.
Now typically, the software comes in a package. Let's say for arguments sake that your download Winzip. Winzip is packed into a file which you download and install. Now Winzip, because they are a business and they have use proprietary techniques which they use for a business advantage actually hide the instructions from the end user, 1) because you don't care, 2) because if it was easily available, people would give it out for free and they would no longer be a business. To actually get to do what this guy is doing, i.e. peep into what the software instructions actually are, you have to "reverse engineer" the software you downloaded.
The ECU works on the same generic principle. You have a map, which is the software, which is provided my Landrover or your favourite tuning supplier to give instructions to the engine based on input from the various sensors. This guy is snooping into the contents of the ECU instructions, to figure out what the heck it is actually doing, so that eventually he can play around at will with the map and do the changes he would want to do to tweak the performance by providing a different set of instructions. Essentially, he is doing trying to understand the contents/instructions of his ECU map so that he can do DIY on it. At least that is what I figured out he's trying to do!
Is that fairly accurate Dippy? Is that understandable Nathan?
