ECU Upgrade didnt work. WHY NOT?
hey guys i went to go get a superchip for my 2003 E500 and when they sent the thing back to Europe, they told me that it wouldnt work for my car because my A/C wouldnt work anymore if they did do this. anybody know why this is, my cousin, ABBOUSHI, here on the forums has a 03 E500 too and did his and didnt have a problem.
