Sorry for the lack of details, it was getting pretty bleary eyed as it was after 1am :)
Yes the only change was to 3 bytes in the extended boost fuel binary code. I was working with Greg who was just about to head out to the land speed races at Lake Gardiner, he was having an issue where he was adding large numbers to the boost fuel table in the extended boost fuel module in ecueditor but he was not seeing the corresponding increases in the fuel signal being sent to the injectors. So i investigated the code and found that the initial state for 3 of the control variables in the extended boost fuel code were not set correctly. When i updated the initial state of the variables Greg created a new bin file and it solved his fueling problems.
