I think that's exactly what happened. It was just a download to fix the senor but it must have reflashed the ecu ,because now the AP can't communicate with it at all. Sucks, because you can't un-install a nissan download. So my temporary fix is getting a new 09 ECU shipped in and installed. And hope it doesn't have the new cold start firmware on it. May have to bite the bullet and go UpRev after I get this all sorted out. Seems like this will be a nightmare down the road. Might have to talk the wife into an early arrival to Z1 or Forge before Zdayz.
