MAF swap
The only dumb question is the one not asked for fear of ridicule.
I am a newb but I refuse to believe that all mods have been tried. Sure, there is a generic tried and true method to everything we do. I just like to explore other options so I ask folks like you who have alot more experiance and knowledge in the area. From the good and bad responses I have recieved I know I can put the idea to rest.
No, I do not plan on a turbo. My plan ... one day ... if it will fit ... is the 3.7v6 out the current mustang. The whole motor only weighs 20lbs more than the 1.8, but that will be after my 1.8 fails or I kill it trying to do some DUMB mod that I didnt ask question about.

You don't even plan on doing engine swaps the correct way. Everything you want to do is half-assed.
Piggyback and Maf swap to get almost-kindof-sortof-not-really to a standalone...
Motor swap that's missing two cylinders...
Racelands instead of a suspension worth a ****...

*disclaimer: I agree with the trend in this thread, waste of effort and money. Get megasquirt or mod your suspension.
That being said, all the brokedicks in the protege/323/escort world "think" it is beneficial to swap the electronics out of the stock vaf(flapper box) into a vaf with a larger body. Typically from the F2/F2t powered mx6 or probes. Look up k-code hybrid for more. IMHO, any "gains" will only exist in your head.
Edit: didn't realize op had an obd-II car.

MAF vs Speed/Density -- in principle, MAF should be better. Instead of baking the VE of the motor into a 3d table so that you can extrapolate from MAP & RPM into a fuel amount, you just directly measure the air going in. As for why it's not more prevalent in the aftermarket, most of the downsides to Speed/Density come from a comparative lack of flexibility in dealing with changes to the motor's VE. With a factory computer that sucks because if you put a better-flowing exhaust on the engine, then suddenly the fueling is all wrong and you can't fix it. With an aftermarket computer it's still wrong, except you have a wideband so the computer can cope and then you just fix it. So S/D is cheaper and easier and doesn't have a major downside, so why use MAF?
People who tune cars with reprogrammable factory computers and factory MAF sensors often stick with the MAF sensor.

That said, swapping to the Rx-7 flapper door on the 1.6 cars is one of the commonly accepted cheap small hp mods. Sure it was only worth a few hp, but the Rx-7 sensors were cheap and easy to get. Doesn't work on a 97 though.
The NB MAF is less restrictive, but I have no idea if it would work with a 97 ECU or not.
NA MAF:
NB MAF:
Looking on ebay, you can get a 99 MAF for $40; let's imagine that it worked right with nothing but some wiring harness hackery (possible, but unlikely) and let's say it's worth 2 hp. At $20/hp that's about the same ratio as a turbo kit. The downside is that you'll be throwing that $40 away if/when you get tired of tiny hp mods that you can't feel and go to a megasquirt. It's the same as how a header is a waste of money when you get tired of piddling little naturally aspirated mods and go with a turbo.

OP has a 97, so he's got a hot wire, not a flapper door.

That's.... not really correct at all. They're using the flapper boxes you speak of, which are not present at all in any KL car.
They're using RX7 units, and the K-code Hybrid is probably something to do with F2-powered 1st gen MX6/Probe.
The KL unit is more of a "sliding booby nipple" type deal. I personally think it's far worse than a flapper, which is probably why those guys pick up so much power with a Millenia MAF conversion.
