Jayw13702 297 Posted January 21 Share Posted January 21 I ran a health check on the IS this evening as I needed to reset the 'check hybrid' warning message. I noticed that within the health check info in the engine section there was a calibration number, in my case is was 353K9000, there were other numbers against other sections. is this an upgrade file? if so is this a dealer only thing or can I get them from other sources?

ianhu 24 Posted January 21 Share Posted January 21 Hi there. Calibration files are essentially ecu updates. With techstream (if you have it) can be applied to the car using the correct process. Regards Ian Quote Link to post Share on other sites
