Last weekend i managed to replace Flapper style afm (My car is 1/2NA-T <-- i hate this word) with Bosch hot wire MAF.
MAF diameter is 75mm and it's from a new diesel car.

At first i tried MAP-sensor, it worked but i didn't get it tuned enough well, there was some problems with lower rpm values.

With MAF and SMT6 car works great, engine behaviour is very smooth and throttle response is more quickly than ever before.

Here is a couple of crappy (camera phone) pics of MAF setup

Post some good pics so all us guys who did do the infamous "1/2 Na-t" can see your setup. Looks good from what I can see considering I have been up all night drinking.

BTW: Do you have a ffi?

is it possible to run the maf after the turbo jus like the turbo guys do with maft to run a vented bov?
I think it's possible, volume of air is same.
I have been running vented bov with afm almost two years, works ok, sometimes little backfire but i just like it :)

Remember that Toyota AFM reads 0-5V the wrong way than normal AFM's (and the SMT6)and you need to build a convertor that changes the volt reading from 5->0V and 0->5V. FrozenOne can explain a little better what he did to make it work.

thats one hell of a sweet setup you got!

Thats pretty cool for a NA-T too bad the 7mGTE has a gay AFM with HZ signal... so much harder to play with.
