Cluster colour change

[Zr6 supercharged]

Hi all i saw a diy for this on this forum about changing the colur of the lights behind the cluster so i went ahead and did it on my aurion sportivo. Only issue i had is when i put the needles back on and put the cluster back in speedo was wrong temp, fuel and revs wer all out now i dont know what to do to fix this. Can someone please help me asap because the car is for family and cant be driving with all the gauges reading wrong. Is it something that will just calibrate its self back or will it need to be fixed or replace would appreciate the help

I would expect that you are going to have to remove the instrument cluster again and try to put the needles back in their original position.

Best to take some before and after photos to assist with getting the needles in the right position.

Revs at idle should be reading in the 600-700 rpm range. Temperature should be reading just below the half way mark. Refill the petrol tank so the reading is showing Full.

As for adjusting the speedo, you could try doing a speed reading comparison with the [corrected] rev reading in 3rd and/or 4th gears at 60kph, 80kph etc.

As a speedo reading guide, 2000 RPM = 70kph in 4th gear.
