[Shotimes] MAF connector question

[Jonathan Zane KC2ENA]

I have had excellent luck with just changing the sensors.  If the MAF you
have came with a sensor attached and it wasn't originally set up for your
SHO you might find that using your stock sensor will correct the problem.
This is of course if the problem is due to calibration.  Then again, some
housings do the calibration based on the size of the sample tube.  There are
too many variables here to say for sure what's going on.  What concerns me
most is the connector problem you mentioned.  Are you sure this MAF is for a
Ford application?  I'm not sure Ford put a 80mm MAF on anything so it might
be a motorsport item which could mean it was ordered for some specific
calibration.   Please provide more information.  Maybe some pictures would
be helpful.  Why do you need an 80mm MAF on a SHO anyway?  Don't they flow
like 1000 CFM or something.  My Mustang runs 12's on a 73mm which if I
recall correctly flows 850 CFM.  There's no way a 3.2 or 3.0 needs a MAF
that large.  How big is your throttle body?

Here's 2 examples of my MAF findings:

Tried to put a 93 cobra MAF (housing and sensor) on my 88 Mustang.  It would
not run correctly.  I swapped the sensor out with my stock one.  Everything
was fine after that.

Got a new 73mm MAF housing for the Mustang.  Wouldn't want that cobra
housing to go to waste so I installed it on my 93 SHO with the stock sensor.
Runs great and there's a noticeable increase in performance.

Is it safe to say that all stock ford housings have the same
characteristics?  I'm thinking this is correct, at least in the Mustang
world.  I was told once that the stock housings and sensors are all the same
and all differences are compensated in the computer.  Makes sense but this
doesn't explain why the cobra sensor didn't work in my car but who knows if
it was any good to start with.  Remember, the reason that there are
calibrated housings and sensors made by aftermarket companies are for people
running non stock injectors with stock computers.  This is not how Ford does
it!  Look at your MAF sensor (black plastic) and see if there is a sticker
or if someone engraved anything into it.  This is a sure sign of an
aftermarket cal.  I'd be willing to bet if you ordered a MAF for a mustang
with stock injectors it would work fine on your SHO.  I've seen people
selling SHO specific MAF's on eBay but I think they are full of crap.
Please someone correct me if I'm wrong.  I am an electronic/RF tech by trade
and I would love to learn more about this.  The entire Ford electronics
system is something I have taken an interest in lately.  Any references or
links would be greatly appreciated.
