Your forgetting that the factory ecu systems for ka/sr are from the 1980's. How are you going to compare an IBM XT desktop to a MacBook pro? Computer systems are antiquated in 3yrs. The CAS on an SR hooked up to a new computer system is like hooking a 5 1/4" floppy drive to a custom built 4 processor server and expecting the information on that floppy disc(designed for dos 1.0) to work. Your comment has cemented my thoughts of you as a so called tuner. Also, the person(Scott) that developed your rom tuning program wasn't a billion dollar company, it was a programmer and his pet project.
