[QUOTE="Acoustic, post: 1346646, member: 728"] hi rollakid christopher we need a minimum "the base map" i.e. idling 1000rpm 20ms injection pulse width on typical 1.6L 4cy approximate 30psi idling fuel pressure approximate best vacuum condition, approximate 250 cc/min injectors at zero tps, at 1v map or 3v afm, etc if the map is all zero, and we only key in above, will not work, because all ecu, including protech will take iteration or average to next rpm. if next data is zero, then crank to start will be forever difficult to impossible if next data is zero, then 1% tps will cause engine to jerk. hence the require of the so called minimum base map is extremely high, not just a few figures they must be exacting..... over an extremely wide range of parameters across all conditions conditions, multiplied over each other many directions and dimensions. when you have good idling map from 0 rpm to 2,000 rpm with tps from 0 to 100% with everything else right, then above 2,000 can be rough, giving fuel consumption anyway from 11 to 17 afr. with this ecu can autotune if you drive long long ecu need information to autotune, and the information come from "time" of driving, making the o2 sensor hot above 600 celcius, driving over all rpm, multiplied over all tps, multiplied over map / afm, plus water temp and air temp and vehicle speed and you need to drive very long time and very long distance over very cold ambient temperature (cold air, cold water) over hard drving and soft driving and you need to repeat all this on very hot afternoon and the ecu is so stupid, it keeps going into autotune, whatever data you collected in the morning are erased when you autotune in the afternoon hence you need to write downn on paper the parameters for water temp, air temp, vehicle speed over varying loads of tps, afm / map etc analysis and morning and afternoon then manually key in temperature compensation and on and on and on and on..... the question come back, do we have the so-called minimum base map??? if we don't even have something we can drive smooth without explosion coming out of our exhaust.....without polis pulling us to one side... i prefer getting someone who knows fuel calculations to make one base map where we consider in theory the behaviouor of our engiine then continue. without the fundamental, how do we troubleshoot in the future..... ??? again this is something same with suspension, everyone wants good setup, but no one bothers to record their changes, giving excuses.... don't know where to get data....... ok lah, i stop lah.
