I'm fitting a 52mm VDO Vision tacho to my V8 and I'm getting some conflicting advice.
It's regarding the 3 coding switches at the rear of the tacho. These are to trim the tacho for 4, 6, or 8 cylinders.
Now I originally misplaced my fitting instructions within the hovel that passes as my garage. I called John at ETB Instruments to find out what position these switches need to be in for the V8. John very kindly replied to me saying that they all needed to be "on". Fair enough.
However today I happened upon the fitting instructions and according to them it should be 1=on 2=on 3=off.
What to do? Does anyone happen to have a VDO tacho in their V8?
