My SL550 suddenly stopped, and my local shop suspected it was my ECU. Their estimate of $3,750 to replace stunned me. I contacted The ECU Pro and decided to give them a try. Took about ten minutes to remove my ECU, boxed it up and sent it to them via UPS. They confirmed that my ECU had failed. Two weeks and about $1,300 later they had a replacement in my hands. Another ten minutes to install, and my car started right up. Now it runs like a top. Great savings and great service. Thanks, guys!
