i search in web without lucky.
from nistune mapping guide:
theoretical pulse width (TP) = MAF Lookup*injection multiplier/RPM
injection Pulse Width = Fuel table [ RPM, TP/256 ] * TP + Injector Latency + Various enrichment.
.......
from sr20 forum. the blue one, Beginners Guide to Chipped ECU Tuning say:
TP = (VQ x K Value / CAS Value) / Number of Cylinders
.......
i try to get into maf vq table using a known LOAD and RPM but my calculations are wrong.
.......
for a nissan b14, stock sr20de, wot, 6000 rpm, maf voltaje is more than 4.0 volts. tp load is at 78.
if i do calculations using nissan guide, i dont get into load 78. if i do reverse calculation, i dont get into a good maf Q value.
maybe there some missing in math calculations.
math tp calculation, help.
