EF Dash Diagnostics
Yet again I must apologise for posting so much in here, but this has been bugging me for a while now.
The EF speedo and Trip Computer speed display both run off the same wire right? Therefore, if one is out, the other will be too?
I know my speedo is out by about 10-15kms - so 80 n is really 70, 100 really 90 etc. The trip computer suggests the same too.
I've heard about a speedo correction box or something that you can get for when you change your diff ratios, any ideas as to whether this may solve my problem?
