NEWS! Apex'i S-AFC II will work

[ForceFed]

Bumpity day!

It would be nice to see if this DAMN thing would work sometime before friggin christmas!
It can't take more than a few hours to install ,so WTF is up!

Geez buddy , we are very busy (it being race season and all) when I get a chance we will try it, I am waiting on the apexi afc II and the guy to bring up his protege5 to hook it up. I'll let you guys know when it's done.

 

[ForceFed]

Not trying to be an a$$ or anything if thats what you thought.
Sorry. I just know if I could get my damn hands on a SAFC 2 ,then I would have already installed and tested it.I have the know how just not the access.I'll be damned if I am gonna fork out over 300 bones on something that I don't know if it will work or not.

I know you guys want it now. we should have some time on mon or tue. to see if it works...

Any News????

 

[Kenetix]

Does it work like Apexi says?

 

[Kenetix]

bump

 

[servoeyes]

Sheesh...I think he meant that they'd have news by next monday. Breathe Kene! Breathe!

 

[Kenetix]

Lol, I know. I just wanna know so bad!

hey peeps,

this is a quote from another thread on the board by agent5568 regarding the s-afc.
--------------------------------------------------------------------------
S-AFC will work
I put a S--AFC on my friends Protege this week. After reading all the post on here that say they will not work, I am here to tell you that they do. It was a b**** getting all the pin outs on the ECU, but I finally have them and the S-AFC works great. I also know of another guy who put one a a turbo charged p5. It has corrected his problem of running too lean under boost. I have attached the pin out diagram. I converted it to a word doc, nobody wants to read my chicken scratch. Any way for all those who say it will not work on the protege's---------YOU ARE WRONG!
Well s***- if anyone want the pin out diagram email me and I will send it to you. I cant post a word do on here~

-------------------------------------------------------------------------

lets hear what everyone thinks.

I think someone should get the pin out.

The problem is the voltages on the old s-afc aren't congruent with those of our sensors, apparently. It will work to read but will not work to adjust. I'm not sure whether or not he meant the S-AFC I or II...different creatures from what the specs say. Either way, I'm sure this kid could be a good resource...just need more BG before we jump to conclusions.

 

[herbieP5]

this would be a great addition to our cars. Even the N/A guys and the future F/I guys could benefit from this.

the MSP guys would lose their minds if this worked I am sure.

(dreaming of a better performing P5..........Sigh )

 

[servoeyes]

Well...us MSP guys would finally have a way to tune the A/F properly. Once the new ECU comes out, we'd be able to run higher boost w/ less problems. Basically, instead of just slapping on an MBC and hoping you can boost to psi w/o detonation and that it will get rid of the hesitation, will be null and void. Now it will require some amount of skill and *gasp* tuning!

 

[herbieP5]

I will keep my fingers crossed.

I dont know why mazda gets the shaft on these good products.

I wish there was more after market support. It is frustrating to not have these options available.

anyone interested should check out

this is regarding the s-afc hooked up in a protege. there are pictures to go along with it and it supposedly works fine.

this isnt even the s-afc 2. this is the first model.

Works fine, but he hasn't gone WOT yet. That's when the ECUs supposedly blocks off everything and just goes to it's own fuel maps. I dunno...I'm not gonna try it until we get some back-up of course. Scientific method, ya know?

 

[flat_black]

Grr... I want one, now. =) We'll see what going WOT brings, then I'll order it if it works. My last hope for staying N/A is to properly tune the A/F ratios. And hopefully get a decent gain. We'll see!

open vs. closed loop, as all modern ecu's (including ours) run. it doesn't block off everything, only the o2 sensor reading to control the air/fuel mixture, which gets replaced by the value in the fuel map when the o2 sensor gets ignored. the reason s-afc wouldn't work was the voltage requirement of our maf (ours- 5-10v, s-afc- 0-5v). i can probably get ahold of an s-afc to test, just not an s-afcII.

 

[servoeyes]

Well...we'll see soon, I guess.

 

[flat_black]

Hmmm... Just was thinking... If I could develop a circuit or someone could that would do the same thing as a FCD for a rotary engine in reference to boost, and tell the ECU that the throttle is 99.9% open, rather than at WOT, conceivably, the ECU wouldn't go to open loop... Just a thought for those with time and electrical knowledge. =) If someone can provide me the source voltage at WOT, I can try it myself, but I'm not that good when it comes to electrical engineering.
