Re: MAP vs MAF FAQ

["John S. Gwynne" <jsg@jsgpc.mrcday.com>]

| MAF advantages
| May have a slight MPG edge

In a closed loop system at steady state (cruise), I would expect the O2
feed back to make the same MPG for both systems.... look forward to
hearing the rational behind this.


| MAF disadvantages

error due to intake track reversion


| MAP disadvantages
| No full time baro compensation

easily changed... an implementation deficiency and not a disadvantage
of using a MAP system.


Questions that remain....

sensor specific limitations of 
  accuracy
  time response
  dependency on other factors such as ambient temperature
