Let's do the math:

If you select a Ramp of "2", and you have 40 degrees of timing set for Boost, the ESC will add 4 degrees (of the 40 degrees you set) every tenth of a second.

.1 sec - 4 degrees
.2 sec - 8 degrees
.3 sec - 12 degrees
.4 sec - 16 degrees
etc...until you reach 40 degrees...

40 @ 4 degrees every.10 sec = 40 degrees of timing in 1 second.

Meaning you will have reached the 40 degrees of boost in 1 second. That is your ramp time.

Ramp Settings:
1 = 2 degrees every 1/10th second - Slowest Ramp
2 = 4 degrees every 1/10th second - Faster Ramp
3 = 6 degrees every 1/10th second - Fastest Ramp

NOW...the ramp starts at your "Start RPM" and you will reach your boost setting at the "End RPM".


whewwwww deep breathe...

Now apply that to Start and End RPM...

So the shorter distance between the Start and End RPM and Ramp will determined how quickly you will add timing.

If you have a Start of 5000 RPM and an end of 10000 RPM you you will add 40 degrees of timing from 5000 RPM to 10000 RPM in about 1 second (if your acceleration is consistent...like on a straightaway).

Clear as mud?
my brains!
