man this is millions of times easier due to the fact that the GUI is all done. there is no definition files to load for GUI for bin or logger files. this program is specific to our car and ECU. wanna change the dead times, you click on the misc tab and unlock the injector box then blam, use + or - or pg up or pg dn and it changes......there are many options to change. Plus you have the ease of mind that everything just works right. The only problem i have with tunerpro isnt the program itself, but i really dont like the idea of people making there own files, that dont have a wholehearted understanding of ECU and opcode and claiming to make these big changes cuz they think they know what is going on without full testing. I dont want people blowing up their car and saying this program sux ect when its not the programs fault, but the person who made the definition.
