Work out the actual percentage error of your speedo reading by using a GPS device or simply follow your mate in his car at a given constant speed.
Once you have the percentage error, use the switches on the Speedohealer to correct the reading.

Hi,
we just compared the speed indicated on the clocks with the back end jacked up so wheels can spin at certain revs in certain gears against the speeds
on this spreadsheet (attached at bottom of post) when you set it up for your engine diff combination from drop downs on graph page.
Can't remember where this came from but was from here somewhere thanks whoever posted it.
(Set revs you want to measure speed at in max revs box for r1 on the data sheet then hover over graph for exact reading for what speed should be
reading on clocks).
Then simplest way to work out how to input this into the speedo healer is to use this
Enter the speed your clocks are reading in the indicated box and the speed you want the clocks to indicate in the actual box (set ours reading a bit
fast for sva to be safe).
Then press calculate and generate instructions and it tells you exactly what to do.
I'd check with other people that the values are right in the spreadsheet first though just to be safe but they were spot on for us.

You probably got it from the link in my sig below 
I can't claim much credit for it though, a chap called Simon Ranson (the one who had the Z100 twin ZX9 Tiger) wrote it about 4 years ago and
posted it on the Yahoo BEC list, I've amended it a few times to put in new engines and to correct a few rev limits but apart from that its all
Simon's work
