I noticed a stickerunder the hood that says "Reconfigured ECM & TCM 6-08-09".
Anyone have an idea why that would need to be done?

 

My TCM was reprogrammed due to upgraded shift program from Jaguar. Not sure if the ECM was redone though.

 

The car came from Las Vegas to Salt Lake. I wonder if the ECM would need to be reconfigured for the altitude difference.

 

What model year is it? Was it just at a dealership in August? I remember there being a '02-'03 recall for reprogramming both, to enhance drive-ability, but that was years ago. After they've been reprogrammed the sticker had to be updated by the Tech.

 

It is a 2007 and was at the dealership in June

 

Found out there was a recall. Emissions Recall J004 Revised On-Board Diagnostic System Software.Effected 04-05 S Type & XJ, 04-06 XK, and 04-07 X-Type. Dealers will recofigure ECM and TCM. TCM reconfiguration is supposed to improve shift quality.
