[Gmecm] Re: MAF specs and MAP replacement.

[Scott Pearson]

I think having MAP and MAF sensors in a GM system is an OBDII feature. I 
can't think of any OBDI units I've seen with both.

So your box will have to take MAP and RPM as a minimum, and will have to
have some constants related to the engine in there also.  What's your
application?  I think most MAF systems fall back on MAP in the case of a
defective MAF sensor, you can probably "convert" to MAP by simply
unplugging the MAF.
