Hi,
My car is a year 1996 ECR33 S2, just got it replaced with a S1 cluster due to RPM gauge drop to zero occasionally, now my Speedo is running lower speed than usual, seems like doing around 60 km/h instead of the actual 100 km/h(I gauge it by RPM needle at 3000), any idea what could be the problem ? Does S1 and S2 meter use the same signal voltage ?
Please note I am not too sure if my S2 comes originally with a S1 or S2 meter cluster, I can't tell which is which..
