Hi All

At a certain percentage of tps which defines open loop, injector
pulse width is determined by a rpm, vs pulswidth table with a 
correction for temp. At least for the general. Also closed loop 
operation is normally entered at a certain defined temp. with a 
check made on O2 sensor performance ie voltage swing.
