Well, I actually just use the original ecuflash, along with my "ecuflash gui v3" to dump and reflash. I just find it easier and simpler.
The new tools are probably even easier to use, I'm just comfy with the older stuff.
For a hex editor I like a couple different ones.
"Ultraedit" is my preference and I also like "hex workshop".
If you use Ultraedit, just go to the range I specified, and look at what you have there. For the rpm and throttle settings imagine that those are your columns and rows of your spreadsheet. The data values are the data thats contained in that spreadsheet. The data values fill the spreadsheet left to right row after row.
You can actually convert these hex values into decimal and then work with them easier. Some are direct values, but most need some conversion to be meaningful.
When you are done, replace the values you want to edit into the rom, then flash it back into your ecu. (Make sure you have a backup of the original first, in case you make a mistake.)
This was the explanation of the way us real men do it. Lol. The easy way is to just use something like "enginuity" to display graphically and change the rom.
Then use your reflashing software to put it back into the car.
