RE: 89 MAF Volt to freq conversion

["Marteney, Steven J." <smarteney@xlvision.com>]

Try this link:

4ds.htm

It is from Electronics Design magazine's Ideas For Design section.  It has
some useful stuff.  There is a much better design I remember seeing in the
magazine but it must be too old for their web archives.

I cannot stress enough just how much demand there is for something like
this.  There is an opportunity here for someone to do a real service to hot
rodding late 80's MAF cars (or to make a lot of $$$$).

You are absolutly right...I'm also shocked no one else has shown interest in
this project now... What I figure to do is use my shop vac with some
restrictors, get 3 or 4 points mapped for the old, the new, and try and
construct a rough fuel curve off of this and fine tune it on the car...
Not an elegant solution by any means, but I think I can make it work...
Anyone have any ideas, refinements, or are you dying to have a good laugh?
I've also thought of trying to find the exact increase in area and flow
mathmatically, and then adjusting the LV8 variables to match so I can be in
the ballpark.
Terry Kelley- does your GMEPro program have this table listed? Seriously
thinking about buying your program... Can you tell me off list what it can
adjust?
Anyone know of any circuit designs for freq to voltage?
I'm basically looking at doing what Bruce proposed a few months ago...
