UPDATE: After updating that template I went back out and was able to successfully (sort of

) flash the car, except I did not know you could not turn the ENGINE on... when it said KEY ON TO CONFIRM I turned the car on... it updated and said SUCCESS...
Except... this morning it drove weird, very very weird.... everytime I shifted into a new gear its like ENGINE BRAKIN starts to happen, it doesn't just cruise like before. I have to press the gas pedal a lot more than before when shifting to keep the rpms stable. Also the car feels very sluggish... what have I done !!! lol
