EH! EH! EH!
...I wrote to uprev and in his forum also.... (my nick is always the same)

At now nothing....
So, I am writing in all forum in the world to found an answer!

Everything is started with this problem:
As manual describe, Ignition Timing express Time Before Top Down Centre (cvs column is "IGN TIMING (BTDC)").
First hypothesis is that are in milliseconds

So, to convert it on degrees I use this simply formula:

Degrees = TA / ms_for_360_degrees * 360
Degrees = TA / (1/RPM * 60 *1000) * 360

Now, in Excel appears only non suitable values like >180°.
Example:in a row of .cvs file I read TA = 28ms, RPM=1100 that result 184°!


It is important because I am studing a software to display statistics in .cvs logs.....
