@spresv: I´m not in a real hurry. If you can give me the measurement after your vacation it would be great!
When running ITB´s it most common to use an Alfa-N map (change the f to ph to get the english word. For some reason it gets censored it i write it like that
) witch means you use RPM for speed and TPS for load. A combination of to speciffic values of each defines a mapsite where you adjust the duration of the injectors until you get the desired AFR.
The ignition mapping works the same way. You define the ignition timing in each map sites in the ignition map.
An inlet air temperature sensor and a water temperature sensor are also normally used to adjust the mix according too temperature and to enrich the mix at cold start(choke)
The MS have an MAP sensor built in. I´ve read somewhere than this could be used to compensate for barometric changes.
Stable idle are achieved by setting the ignition a bit lover in certain ignition map sites. When the rpm rises and reach the site with a lover ignition the rpm falls again. Actually the rpm are going up and down but so little that it still feels stable.
Modern mappable management can control allmost anything as long as it gets the relevant input, but the most normal functions is injection and ignition. A basic setup can take care of the same things as the original ECU and more. Its up to you really.
The man behind Emerald
, Dave walker have written really good book about the subject
. For some reason it doesent seem to be avaliable through Haynes anymore.
