You Think?
I will loan you a twin channel emulator then and you can alter the boost map in here for me yeah?
Can we have the other half please (preferably with address offsets).
In answer to his question though, the tools of the job are cheap nowadays. Its the clunky mapping process you have to get around (which the RP labs modification will do). And as Stu effectively points out, knowing the memory addresses for the various maps is a time consuming thing to work out.
Not a difficult job once you a) have the calibration portion of the memory (as half dumped above) b) know roughly what the different maps look like c) understand the resolution of the values for a given maps. There are other approaches to working this lot out, generally by disassembling the firmware of the ECU. Again, easy with the right tools and having half an understanding on what you're looking for.
Cheers.
