ECU Pro did an outstanding job of troubleshooting my 2003 SL500 EIS module and recommending the correct course of action to get me back up and running. They were very thorough and offered options to correct the issue. There communication via email was fast and accurate and easy to understand. The replacement EIS is back in the car and works perfectly with the newly programmed extra FOB. Shipping are repairs were fast.
