Dont worry about line 26 and 27
It was supposed to be top speed per gear with 16" and 17" rims

you only put your speed in column B row 14 and it should change the rpm in all the engine rpm row

that one should work fine just enter your orginal rims and tyre and diff ratio then enter your new ones and itll tell you how much your speedo will be out
it all so helps you with what gears to change to if you need to replace the sensor gears
