davidreader5 the magazine is wrong

nothing has been done to the ecu to change the number of "mapping sites" - the L8 came out of the factory with lambda control enabled. as far as i know, all that needs doing to cope with larger injectors is tuning of the PID characteristics of the closed loop control.

the ECU just runs a set of instructions. it will have a set of instructions in it that say if the water temperature is high enough and the throttle pot is at rest, i.e. the engine is idling, then use the closed loop control to give the correct fuelling for lambda control. if these parameters are not met, use the values from the map.

similarly, in cruise mode it can use closed loop control, until such time as the boost or engine speed or whatever goes outside of the values in the instructions and then it uses values from the map.

i know perfectly well how closed loop PID control works, i use things everyday that i have programmed to use this method in the control of the climatic wind tunnel that i run

i think that you need to go off and read about it, here's a link
