Tuner Pro RT (Real-Time) is a free, feature-rich software package designed for reading, editing, and burning tuning data to a wide range of OBD1 and early OBD2 vehicle ECUs. Developed by Mark Mansur, this software has become the gold standard for hobbyists, budget-minded racers, and professional tuners working on legacy platforms like GM’s ‘7730, Ford’s EEC-IV, Honda’s OBD1, and many others.

For decades, professional tuning software has been locked behind expensive licenses, proprietary hardware, and steep learning curves. Tuner Pro RT changes that paradigm entirely.
