    Read the manual? http://www.aemelectronics.com/Images/Products/Installation Instructions 30-6820.pdf

    "Check Engine Light
    The Low Side 10 output (LS10) activates the Check Engine Light on the gauge cluster. It is
    configured to activate at low RPM in the AEM startup calibrations; this can be reconfigured
    by selecting Tools>>Configure Outputs."


    Do you have the AEM program on a computer that you can connect to it?

    I for sure don't. Reading that line in the manual it sounds like the tuner could have made the CEL come on for a custom reason. Maybe. Do you have a cable that came with the car? USB or serial? Something is required to get the software/computer to talk to the hardware in the car. Although based on this limited conversation it sounds like maybe you shouldn't. Another thought is when was the battery replaced. Have you changed something in the car at all? Does it run ok? Are you in the Twin Cities? Call RS Motors?

    Good luck.
