You take a bin file that you edit with tuner cat or tuner pro, and you use a GUI that I wrote to upload it to the ECM via the ALDL port. Instead of burning that bin into a chip, you upload it...
If in the future Mangus wants to add support to TunerPro R/T, then we would have the ability to tune real-time with the module. But for now, it's old school. No big deal really. I like to make small changes slowly and create a bunch of incremental bin's that I can revert back to if I choose.
Which end of O-town are you in?
