Need hypertech/efi cant do

Find out the percentage it is off. Add or subtract that percent from the current reading, be it dia, rev/mile, etc. This works for all tuners that can adjust the speedo, and all types of vehicles.
Are you using EFILive or HyperTech?

Example: If you are off 5 mph at 50mph (actual = 55, speedo = 50), 5/50 = .1 = 10%.
If it goes by tire dia, say 33 inches, you multiply 33 x .1 = 3.3. Add 33 + 3.3 = 36.3.
If it's rev's per mile, say 600, then 600*.1 = 60. In this case, you go backwards, subtract 600 - 60, and type in 540.
Check it with a GPS and fine tune.
AS I REMEMBER... If I'm wrong, someone should step in. My math sucks lately.

It goes by tire dia on LB7/LLY. It goes by revs per mile if you are LBZ+.
There is a Speedo section to your left on the screen.
I don't do a lot speedo correction lately, so my memory is poor. I only tune my own stuff now.
