Readers Digest Condensed Book of Porsche MAF's...
Does anyone have a copy should it exist??? Can I borrow it???
I don't know much of anything about fuel injection. Most cars that I've tinkered with have had carbs...
I stopped in to check on my car, a car which has been in 2 different shops now, for about 4 months, and found that it's basically done, albeit, someone along the lines lost my MAF and it's holding things up.
Tried to get the first shop to cough it up. I got ejected from the first shop upon my cheerful inquiry.
I am probably covered, as Roger is on it, and should be able to assist.
The thing is, I'm curious, and I'm afraid if I even consider reading much more into it, that my head will explode, as if it was just redlined with a 20 year old timing belt or something.
I do intend to supercharge my car, as soon as it's back long enough to work all remaining bugs out and assure that it's tip-top and ready for forced aspiration.
I see postings about aftermarket fuel injection systems, mostly being mentioned, it seems, with cars that are supercharged. A MAF is a surprisingly expensive device, I fear.
Is there much to be said about further complicating things with most anything other than just replacing this pricey part with what used to be in its place? I take it that aftermarket fuel injection systems USE the factory MAF?
There doesn't seem to be any plain, aftermarket MAF's for my 1989 928S4. I have discovered some new aftermarket MAF's for later cars, like the 99-something or other. In it's case, a new one is barely over $100 from what I recall.
Are there any solutions worth considering if I'm stuck with a MAF-less car, mandating transplant of that seemingly pricey organ?
Like I implied, if I try to "understand" fuel injection right now, I fear for my sanity. I tend to compulsively read, and that subject seems just too dam big for me right now...

The 928 MAF is one of the best MAFs Bosch ever produced. Designed specificially for the 928. It is a hot wire MAF and has an extremely fast response time. They typically last at least 75k miles .
Modern MAFs are hot film and do not have a great lifetime.
There are prenty of s/c 928s using the 928 MAF plus all the original 928 FI system, often tuned with the SharkTuner.
