I found a 2008 TSX AT ecu at the junkyard. Cost me $100 flat. It's in mint condition. I also have an '08 AT. I am not 100% sure but if I install this into my car, is it a direct plug and play or my keys, etc needs to be reflashed? Reason for installing this is to tackle a nagging TPMS issue I've been dealing with. I've swapped out everything from sensors to the receiver. Don't know where the RF interference is coming back but it can't hurt to try an ECU swap.
