I really hope to find some answers here because I'm at my wit's end. My car's been in the shop for over a year. And for the past couple months everything's been at a standstill. The car has a base map it's running on but I'm told no one can finish tuning because there isn't a trigger in the software to activate vvti. The shop assures me that everything on the Toyota side is good and operating normal. That they can manually activate it but the computer doesn't do it on its own. Does anyone have any idea what's going on?
