like many I did the exhaust pipe disconnect mod on my 07 pre LP spyder but I keep getting the cel warnings and exhaust valve error which I need to clear often.
Is it possible to modify the ECU settings to not check for exhaust valve ?
Did you leave the supply side of the vacuum hooked up? You only need to cap off the side that goes to the vacuum line that then splits off and runs to the actuators. If your getting a CEL with it hooked up and properly capped than theres another issue.
