link not working....PM me an email address and I'll send it to you if I haven't found a host site yet

If you have a data logger capable of logging time, speed and rpm this will work for you, I also have a volumetric efficency sheet in this too.

This was put together assuming UpRev Cipher log files but any data logger will work but you need to use the same column heading as Cipher uses.....all explained on the readme tab....
