[Diy_efi] What Injector Is This?

[Perry Harrington]

Mike,

My Probst book has a blurb about the MAF, I'll fine the schematic
of it elsewhere.

The cold wire which is not exposed to the air stream is not heated,
it simply is a thermister.  The Hot wire is heated to 200C above
ambient, so you can see, it's always very hot.

Those who would give up essential liberty to purchase a little temporary safety
deserve neither liberty or safety. Nor, are they likely to end up with either.
