OK, First off I'm a total noob at this. I changed my shift points, line pressure, and abuse settings. I screwed it all up, but thought it wasn't a big deal. I'll just re flash with my factory settings...... Long story short it won't flash back. After 3 attempts i cant get back to where I started. Is there any help for me?
