hi,i have a questions about the gdb sti open source tuning maf scaling,may i know when open loop maf scaling need disable boost controller (wgdc 0) or use normal target boost pressure?
below this maf scaling method correct?
primary open loop fuel map all open loop cell set to target 11.0AFR
2 WOT 4rd gear logs from 2000rpm to redline (wgdc 0) boost controller disable
2 WOT 4rd gear logs from 2000rpm to redline (normal wgdc target boost pressure)
use the maf scaling software filter out all non WOT data and closed loop Mass Airflow Sensor Voltage (below 2.89v)
problem is when use different boost log with same maf voltage get difference AFR and maf scaling correction.
2 different boost(wgdc0 and normal wgdc) log average the data for maf scaling correction or only normal target boost WOT log? which one method better or any other idea?

Iv'e always scaled the MAF using the actual boost I intend to run. It's likely that you may see some variation in the MAF due to resonance and this may affect the accuracy of the MAF reading at some points. I would prefer to have my MAF sensor more accurate under the conditions I'm going to actually be running - ie the actual boost level the engine will see.
