True plug and go True plug and go. I've bought several from them and each one worked like a charm. Didn't even have to reprogram the key fobs. It's the only company I use if I need a computer.

More like Mary A+ :) I ordered an engine control module for a Nissan Maxima because FS1 has the best price by far, and they could program the ECM so it would be plug and play. The part was programmed within a few days but the testing took longer than expected due to issues with their testing department. That resulted in the part taking two full weeks to ship which wasn't ideal, but Mary A stayed in contact with me the entire time and provided updates literally every 48 hours. Normally, I would have gotten frustrated, but it was hard to do that because Mary A was so great. I haven't installed the part to know if it works yet, but I have to commend the service Mary provided. She was great. Thanks Mary and FS1!
