MAF vs MAP

[lkurek at smtpgate.anl.gov]

     MAF is a better system theoretically than a MAP system. The reason for 
     this is that you are MEASURING airflow/density rather than calculating 
     it. In practice, a MAF system is harder to package and there is an 
     inverse relationship between peak airflow potential of the MAF and its 
     accuracy. The stock GM 3" sensor (i.e. 85-89 TPI) is fairly inadequate 
     for a healthy motor (325+hp)...it just won't flow enough air. If I 
     could somehow get a late model 3.5" MAF to work with my 89 
     harness/computer....that would probably be best...but I have no clue 
     if/whether this would work.
     
     TTYL!

So is MAF considered inferior to MAP?  Just curious.  Seems that, in theory, 
MAF is a more "direct" reading and that MAP uses estimates... 
clarifications??  (thanks).

     Guys:
     
     Does anyone on this list have a GM compatible (DFI, Haltech, etc) 
     programmable ECM that they would be willing to part with? I have an 89 
     TPI system that I need to get some control over...not to mention 
     ditching the MAF.
     
     Please reply in private...
     
     Thanks!
