BUMMER! This past year, I've been traveling and tuning all around the country. I've made it a habit (he he) of TUNING ALL MY RENTALS!
This past week I got to the Corvette Museum in Bowling Green Kentucky and rented a nice white 08 Chevy HHR.
I whipped out the laptop and was hoping to download the engine and trans cal to give the little bugger some needed Git-up-n-GO!
To my surprise, I couldn't even connect to the (I think it was E37?) engine controller and when I downloaded the T42 file, it came up as unrecognized!!!
OK PAUL AND ROSS! You've got some explaining to do!!!
I drove around SLOW all week!
