Hello please help I accidentally tried downloading a custom ECM tune while attempting to stick the suction cup that holds my mm3 display on the windshield it wouldn't let me go back to the previous screen so I
hit the continue button and it proceeded to try and download the LP-170 ECM tune and then said Extended Error with a long code and told me to save this message, it couldn't do whatever it was trying to do and
said it would have to fix the problem by re configuring the stock file or something along those lines. That download finished it told me to turn key off, turn key on blah blah and then all these codes popped up,
check engine light, ABS, DEF system service required see dealer, exhaust system service required see dealer. My truck runs like **** and I don't want to break anything. Please tell me someone knows how to undo
this mess.
