right guys i have a GT engine and gearbox on my car, i have standard 1.3 NA clocks . it has a speedo converter on it , the speed reads in KM in the inside ring but the mileage that comes out reads rubbish, to work it out i have to times it by like 1.57 if i took the converter off, would it read on the mph ring on the speedo and the mileage would be correct? Thanks Dave
