C4 upgraded system leaves a SYS blinking light next to speedo?
Hey guys,
I have a little bit of an understanding that the issue I'm describting relates to a closed circiut that requires a resistor on the stock wiring of the CD player, but could someone elaborate?
The reason I ask, is the ECU doesn't correctly read data tables and under sub WOT I tend to get a hesitation that only happens when the SYS next to my speedo blinks.
