Timing algorithm
 

I was planning on writing a application using java that is a basic base mapper. The main reason i want to make it is because i want to learn java and it seems like a resonable first application.

What is the algorithm for the standard linear retard and step retard.

thanks

There is no algorithym...its basic math.

For linear just take that last vacuum column and subtract the column heading times the - linear degree of retard.

Example..

If the last column is 28 degrees of advance. At 1.4 psi and a linear retard of -.7 degrees, the new value would be...

28 + (1.4 * -.7) = 27.02 degrees of advance

For stepped...do the same thing but break it down in by a group of boost column headings. For 0-2 psi, the retard would be -.3, for 3-5psi, -.6, for 6-10, -1.0. So with that same example...

28 + (1psi * -.3) = 27.7 degrees of advance
28 + (2psi * -.3) = 27.4 degrees of advance
28 + (3psi * -.6) = 26.2 degrees of advance
28 + (4psi * -.6) = 25.6 degrees of advance
28 + (5psi * -.6) = 25.0 degrees of advance
28 + (6psi * -1.0) = 22.0 degrees of advance
28 + (7psi * -1.0) = 21.0 degrees of advance
28 + (8psi * -1.0) = 20.0 degrees of advance
28 + (9psi * -1.0) = 19.0 degrees of advance
