So, I've been running strong with Ray's tunes for 4.5 years.
It still runs wicked awesome, but I have an illuminated check engine light on the dash.
I'm not a mechanic, but I wondered if the MM3 controller could tell me the code for the check engine light.
Yes; from the gauge screen, touch the display, select “MAIN MENU” then select “ECM” then select “DTCs”.
Post your trouble code, and I will attach some helpful troubleshooting information.
