PERFECT POWER XMS4A – Engine Management System DIY MANUAL V2.1
25.3 IDLE SETUP
The XMS4A can be programmed to
idle at different speeds as the
engine temperature changes. To
set the idle speed use the “F9”
map and the “Idle rpm target”
map.
25.4 FUEL SETUP WITH AMP
A good fuel map to start up on should have the same values in the main fuel map. The amp
multiplier should have the same values as the amp gradient. Now the only thing you may need
to setup is the fuel range. The “first start” map (which you have loaded already in the section
before this one) has a fuel range of 2.5 this number can be adjusted up or down depending
the amount of fuel needed. Only one number to tune makes for quick adjustment of the entire
fuel range.
