Speedo healer set up
Hi,
I set up my speedo healer using a sat nav, drove it until the sat nav said 60 and i made a note that the clocks read 108.
I put this into the speedo healer online calculator and it told me i had a error of -44.4%
I put this value into my speedohealer and presented it for SVA.
I failed the Speedo calibration test at SVA by a small margin, the vehicle was traveling at 72mph when the clocks said 70.
An error according to the speedohealer calculator of +2.9% ( based on my initial setting).
My question is.....
Do i add +2.9% to my -44.4% reading to get a new calibration figure of -41.5?

yes but it either tells you to 'reset' the speedohealer and i would then need a fresh set of readings ie turning up to SVA having not done
anything with the speedo healer.
If i reset the unit my readings would be back to the same as before approx 60 reading approx 108 again.
i cant just reprograme the unit with the +2.9 reading or it will be WAY off.

Working backwards from your SVA figures - 72mph on the SVA rollers would have read 123.67mph with SH reset to 0. If you used a figure of -40% this
would give you a speedo reading of 74mph at an SVA measured speed of 72mph. This would be a better bet so you are giving yourself a small margin for
error. All production cars over read by a small margin.
