Andy1972 Posted February 19, 2019 Share Posted February 19, 2019 (edited) I recently acquired a 2003 350Z automatic import. Someone has obviously taken the trouble to replace the instrument cluster with one in mph. However I don't think they have calibrate it! An example: GPS speed 50 mph Speedo speed 37 mph Trip computer speed 50 kph So it looks like the trip computer speed readout is displaying mph correctly but saying it is kph, whilst I have noticed that the Speedo undereads by approx 13mph throughout the speed range I have tried. Any ideas On how to go about fixing? Presently using the trip computer speed readout so not too much of an issue, more of a small annoyance !
