Hi, we bought a lot of ECUs from you in ebay (Yong Sheng Automotive Co, LTD in Taiwan http://www.autotronic.com.tw/index_en.asp). Do you have any sale department we can contact directly because we have a huge demand. We also want to establish a long term sale relationship with you. Could you direct this inquiry to the party who can discuss this issue? Thank you very much. My phone number is .
