Like a few other people on the board I use the better carbon/paper pollen filter in my brick, and just like Dave (Spinning Wheel) wrote recently, the instructions say that the ECC should be re-programmed when said filter is installed. However, my local very reputable indy mechanic did not know anything about this or what exactly is to supposed to be done. Does anyone here know the exact details? He and I were also wondering if said reprogramming applies to the carbon/paper filter only, or if it applies to both style filters and is applicable when the pollen filter kit is first installed. Any insight would be greatly appreciated.
