i have found the cure, get a fuel pressure regulator and boost the fuel psi by 10 psi, i did that on mine with my begi rrfpr because i will be boosting soon , so i put it on.. and no more hesitiaton, smoooth rpm band, more power... works great... here are some pics..

Is that means you waste more fuel by boosting the fuel pressure? Also how much is that fuel pressure regulator?
 
it might fix the 1.6 cai hesitiaton. But it doesn't get rid of the stupid check engine light that always comes on from the cai. But with a n/a setup it is already running on the rich side, with the regulator it is even more.

How soon do you plan on boosting?

once iget settled in on my new job and school, so prollly a month or 2...

Oh wow! Very cool. Do you have your kit and needed accessories gathered already? Or are you about to buy a complete kit? What PSI do you plan on boosting to?
 
i have my fuel system done, and pipeing will be custom by a friend.. the 2 parts i need are the turbo and manifold, once i get them , its only a matter of getting all the fittings for the oil and coolant to turbo setup, the boosting to 6psi, and when i get an intercooler 7-8 psi..
 
Sounds good. Let me know how everything comes about when its up and running. I want to boost in the future but a little leery about screwing up my tranny. Sounds like you know what you're doing though. Best of luck though.

Means to set the fuel regulator to 10psi? which is 0.7bar approx? I had a fuel regulator gauge, and i set it to 2 bar??
 
Has anyone tried using a MAF sensor off another Mazda? Maybe a 626 or Miata? I have never looked to see if they would plug in, or if they're compatible with the computer. I hate looking at that damn check engine light, and the hesitation sucks.

BUMP from the dead.

OK here is the idea, i want to go Supercharged or turbo but that is down the road BUT I want to try this and see how it will work out in a N/A car and if it will Bump up the power.

I got a SW A/F gauge (Not wide band cause i am a cheap dutch guy) will i be able ot tune it right using this or will i be running it so rich thing's will die ??

I need more info, but i would love to try this.
