in order to dial in the VE properly you need to make sure that the engine is running completely off the VE table without the MAF interfering.
once you have the VE dialed in then you can reconnect the MAF and adjust maf

Fail frequency has always worked for me. If its not I suspect the code has been turned off in your pcm file.

until your VE is dialed in perfect...then its not going to be accurate...
plain and simple... it used the VE to get its #'s for accuracy...
only way to correctly and accurately get the MAF is to use a wideband and use AFR error % to get it right
