STAY AWAY from car computer exchange at all cost!!! hand delivered a PCM there, called back 2-3 days like they requested only to be put on hold and ignored. Went back in person only to be ignored in person, not even acknowledged at all while I stood in their office (at this point I have read all the horrible reviews and know without a doubt I have been screwed). Well today, nearly 6 months to the day of the PCM being dropped off I get a call wanting to know "if I still want to do business" and that my "PCU tested fine" and "for $100.00 I can get my PCU back". So, I went back got my PCM in my hand said a smiling "Thank You" and walked right out. Now, my PCM is damaged/bent at the corners where the screws hold the 2 pieces together and also missing 2 of the screws. So, that is my experience with car computer exchange. I advise to stay away from them at all cost.
