If you put a 86-88 air flow meter on a gsl-se. I have red about the max7 one but was wonder if by putting one on a adjusting it with the screw on the side that leans and richens can i work it that way instead of changing the guts in them.

 

Negatory. And even changing the guts in them you need to recalibrate it using a
bar analyzer machine to get it right. rx7doctor

 

Here's what Jim Rothe from the SA22C.org email list has to say on the subject:

http://www.jimrothe.com/mazda/afm_project/index.html

He abandoned that project due to complexity, I believe.

 

If you want to get some more flow into the system without changing the AFM.
Put on the S4 injection/induction system and get one of guitar28junkies ported t/bodies. Run your se injectors in their existing posistion and forget about the secondary injectorys. rx7doctor

 

if this is the case of swapping over to an s4 injection system then wouldnt the SE afm be the restriction?

 

how much would i pay at the junkyard for this

 

Anyway you look at it a AFM is restrictive. But the runners/plenum and t/body are larger on the S4 which means better usage of allowable flow. rx7doctor

 

has anyone on the forum been succesful at this if not im willing to try this just what is needed the intake manifold upper and lower some new gaskets and some rubber caps or plugs. i no a local yard that had an 86 in it and what kind of HP numbers are we talking about here 10- 20.

 

doesnt that also put the afm on the other side of the motor you would need an cone filter and some modifications im not sure can any one enlighten me on the topic id like to try it out.

Something I've been wondering, since JET can reprogram SE computers, couldn't they just change the calibration to work with the larger AFM as is?

May I be the first to mention that megasquirt is probably easier, maybe cheaper and will definately pose the least restriction.

As for Jet, I am not too impressed with them. They want to charge you x amount of dollars for a ECU reprogram but they can not tell you how much hp you would gain from the reprogram. I say forget Jet.


As for the Megasquirt how easy is it????

 

Lets light the flame for Megasquirt. I have to put together my whole entire wire harness and parts so its just as easy if I use mega-squirt. Tell me the ingredients, I'll buy them and we'll have a community input on it, and thats what I'll use. Mabye more of you guys will get them also? Want me to make a webpage or something to keep track of this? Yell back at me about it. 2 injectors, a tps and some other crap isnt to complicated right?

 

I'm sure Megasquirt is as good as I've heard but I'm not out to reinvent the wheel. And I don't need a tuning company to tell me how much HP my engine will make, I build them to make the HP I'll say they make. I've just been wondering if it would be a simple table swap in the ECU to convert over to the bigger AFM. I could get one at a pick a part for less than $20 and be done with air measurment on my street car.

So while I wish anyone well on developing better engine managment systems that can be installed at home I hope that this thread stays on topic and that someone who knows can answer the question. I've searched before for the answer and not found any. But there's plenty of info on Megasquirt all over the net.

You can run the s4 ecu and harness if you want to run the s4 air flow meter. If you do that then use the s4 uim, liu, and tb also for more hp gains.

 

You don't even really need the TPS if you don't want. http://www.megasquirt.info/manual/rotary.htm should have all the info you need, including a base map to get a GSL-SE running. There are also significant fuel milage savings to be had because if your not running cats you can lean out a good deal of the low-rpm range without fear of destroying them. Most megasquirted rotaries are returning a regular 30MPG on the highway.

Thanks for the info FIRE, would you happen to know a link with more details? That sounds like something to try.
