The Curve Changer will alter and improve your ignition map profile.
The reason the curve changer works is that the standard ignition is a generalisation for all
... it is not too difficult to tune, suitable for all fuels, all gearing, etc.
After designing a programmable ignition for the RS1250 and RS125 Power Valve, the
largest requirement was to increase the drive area advance, without then causing the over
rev to 'brick wall' do to its increased compression effect. A simper lower cost unit could
provide this requirement. … The curve changer
The largest advantage is in the increase in the spread of power
The 16 settings unit is an enhancement of the standard RS125 Curve Changer. It allows a
switch selectable range of map alteration.
By using fixed switch values the result is accurate and repeatable.
The switch has 16 positions 0..9,A,B,C,D,E,F:
(0) Is 80% of the standard curve changer value.
(8) Is the same as the standard curve changer value.
(F) Is 120% of the standard curve changer value.
Each switch position is a 2.5% step in the curve changer value. With a higher curve
changer switch values the static advance will need to be advanced.
