[QUOTE="nan83, post: 1063393379, member: 6718"] viton... so far so good.... still not give any prob yet.. but my engine still run low boost.. maybe next 3 week i will dyno it... baro sensor = detect absolute pressure (ambient press).. sea level = 1bar , genting maybe 0.85bar.. this will link to fuel baro correction map.. normally we lock it at 1bar o2 control valve?? you mean o2 close loop system ?? o2 sensor detect afr... ecu set the target.. so the ecu will try to adjust AFR to the the target we set by altering the injection mS .... idle control = the idle stepper motor will control by ecu base on set point we set... exp. 1000rpm .. ecu will try to maintain that rpm by open or close the stepper motor... the o2 control & idle control also have other control parameter to set.... how sensitive it will respond to disturbance.... we not set it correctly.... the output will go more crazy... so it not as simple as we think... hehehe... we want good afr with close loop.... end of result it will give more fuel consumption if we not set it correctly.... first we need to have very good base map, the last is we set the close loop system... so base map give stable afr reading, than the close loop system will take less job to correct the parameter... if base map not stable.. afr 13... than shoot to 14.. than shoot to 12.. the close loop system oso can gila.... huhuhu.. it take time to do correction, it no so fast algorithm & calculation...
