Who can help help me with this?I can't seem to find any step by step instructions on tuning for dummies,4 years ago I downloaded and installed the gst tune for my 2011 ralliart using the open ecu with lots of help from club ralliart guiding me through,now back then the open ecu had a list of numbers that I had to bring over the definitions for the car and drop in,now the updated open ecu when you go into it and access rommadata/mitsubishi/evo has the definition numbers already there...bottom line does the tune now include those definitions or in the open ecu,I want to go from 93oct to 91,also can it be just changed or should you revert back to the stock tune first?
It would be great if there was a thread that helped .
