Alright i just have a quick question.... would it be better for me to save up for the UNICHIP or just go ahead and get the APEX AFC and o2 wideband???

And has anyone here tuned an AFC??????? with the o2 wideband???

Any replies would be great...
 
I mean... i read the TURBO magazine with the mazdaspeed hooked up to the AFC... so what gives man?
 
Weird..... cuz i have the magazine right here with everything hooked up.... grrr this is frustrating me, just because i can get the AFC for a good deal...
 
sorry man thats the avc-r they hooked up oin the msp in turbo mag......the afc needs o2 modifier or clamp to possibly work...but no one has posted on here with it working
 
Actually someone has posted that they have a working SAFC2 on their car as well as a greddy E-01 and it does work, but the usual assholes gave him s*** and he's keeping it to himself. I've seen it he lives here in AZ and it works great. Anyways, it works just not easily.
 
The usual assholes? All i want to see are some wiring digrams and some facts so people (like myself) can stop saying "SAFC doesnt work".
 
So would it be better for me to just go get the UNICHIP???? or try to get the AVC-R???
 
the AVC-R is apexi's version of an electronic boost controller, the SAFC 2 is their newest air/fuel computer. i havent really looked into anything in depth but i was somewhat thinking about trying this myself in the future because i like the fact itll pull timing if the knock sensor goes off and such. just dont attempt it if you arent a master of wiring and tuning cause im 99.9% possitive there will be a TON of wire tapping to do on your ecu and you dont wanna screw that up.
 
But AFC doesnt control timming. Thus why it is so affordable. You can try but I havent heard of anyone getting it to work. Unichip is guarantee to work without any hassel...just plug and play.
 
I agree with the Unichip. You can only believe about 75% of what's put in magazines. Most of it is hype and while it may work on at least ONE application (granted, it's in a magazine) that doesn't mean that it will work for you. I'm sure there was no "how-to" in there on the AFC. The Unichip has had nothing but compliments and actual users that agree with the advantages. It's also plug and play like spacemonkey said, so save your money.
 
afc should work like the e mange you need a voltage clamp and a afc for better performance some injectors and fuel pump.


thanks justin h
 
If you want something to tune yourself Unichip is not the way to go obviously, if you want something that you cant play with then Unichip is the way to go.

The AFC will probably work I think with an O2 Modifier but I prefer to go Emanage or MPI.
 
If you want something to play with you should go with AEM PnP standalone...thats probally more self explanitory and userfriendly then any other EMU. But its gonna cost you...still not too expensive for the average MSPeeder. Its mad tite you can be just like Paul Walker in Fast and the furious! Cool looking graphs and big warning signs on laptop = FAST!
 
I think someone was actually working on getting the S-AFC to work and has not updated us yet. I would love to see someone get this thing working on our car.
 
Speedoc went to a authorized Apexi S-AFC tuner and was told that it will NOT work do to the ecu voltage on our cars. Apparently that is why it will not work.
 
OK, Please understand that I do not know a lot about the electrical systems of our cars, BUT. When I was talking to my friend with the working SAFC2 controller he said that all he did was plug into the MAP sensor instead of the MAF sensor. Didn't make sense to me at first but then I started to think. Mind you we werent really focused on the subject at the time of the phone call. I searched the board looking to see if we had a map and came across this post by chdesign....

"Actually we do have a MAP sensor as well it is called a Boost Sensor on diagrams though. The easiest way to find it is to look at your vacuum diagram on the top of your hood. It is located in teh passengers corner of the engine bay."

So i found the diagram and it is on the passenger side of the car. I have read that the SAFC2 doesnt work because our MAF reads 0-5v and the SAFC2 runs at 5-10v. Ok, cool, but when I plug into the MAP aka Boost Sensor, the pink wire reads 5v, the orange doesnt read, and the red and blue wire reads about 3.26v and raises to ~5v when i hooked up the vacuum gauge. This is with the car nor running because it is taken apart now.

So I'm thinking that if we plug into that, someone with a little more knowlege, might be able to use that rather than the MAF. Just an idea! (shrug)
