I have a question about the hondata s100 that I have. had a problem with my prelude this weekend and monday I am going to have to unhook the battery in my car, will this erase the tuning that I have done? I have had my car dyno tuned for about 3 hours to get my car to run the stage 2 cams and other things with perfect idle and dont want to lose that tuning time. I also will have to make an appointment for tuning if it will be erased as well, any help will be greatly appreciated!!!!
