C8 Exhaust CEL
So I installed a Corsa extreme exhaust a few weeks ago and the sound is Amazing!! I purchased the one where I swapped the factory AFM valves, hoping to not throw a CEL. Well that didn't work. CEL went on so I took it to the dealership to do a re-learn and that didn't work either. They still charged me $370 for their troubles. I ordered the Cicio performance module and installed that quickly, drove around for about 35 miles and CEL was still on. I unplugged the battery for a few hours and voila, no more CEL.... until lunch the next day. CEL is back on, so I hooked up my code reader and attempted to clear the code which also worked for about 5 mins. is there any 100% solution to this problem. I contacted Cicio Performance to see what they recommend, but I'm still awaiting their response. Does anyone know if there is a difference with Cicio's and Paragon performances AFM modules??
