I was looking at the Apexi SAFCII, and was wondering if anyone knew if we could somehow get these to work on our cars? They are very nice looking, and it would be sick if we could do our own A/F tuning..... Im sure it relies on our ECU being cracked, but i was just wondering if anyone knew.......

 

Revitup tried it, and it didn't work out so well.

 

that sucks, why didnt it work? because of our pcm's??

 

This is a PM i recieved from a member of *************

Re: Questions about your setup

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

Sorry for the late reply, Ive been out of town on a buisness trip

#1:The RPM adapter is not off of a 350Z, its a greddy type1 rpm adapter. The type1 is specificly disigned for the 350Z/G35, it just happens to work on our car. I got this info straight from a Greddy tech rep.

#2: The S-AFC is installed the same way, and conected to the same wires. How ever, the greddy is tuned through a windows based greddy program as where the user tunes the safc. The disadvantage: you cant retune your car with out taking it into a greddy otherised dealer. Advantage: You have much more options in what/how you want your car tuned.

#3: My Greddy setup allows you to add and pull fuel, change timming, and redline.

#4: We used a OBDII to track knock retard, and used the e-manage + ignition harness to adjust timming and fuel accordingly.

Hope this helps. Any more questions, feel free to hit me up...

Joe

Someone should try to confirm this information, because if it works, you'd be able to use an AFC2, and it would make all your lives a lot easier

 

This part confuses me...

 

please be more specific about your confusion, i'd assume you mean why do you have to go to a greddy authorized dealer for tuning, well that i cant explain, maybe he doesnt have the software. the user is gm3saturn on the .com forum. i'd post the link to the thread but this site blocks the letters.

 

I dont what the point of having the SAFC II is if you can tune it yourself. Why should I have to bring my device anywhere.

 

Im confused.... whered greddy come from? i was looking at Apexi????

 

lol, WTF exactly Apexi makes the SAFC not greddy

 

i believe in order to make it work you need an rpm adapter, much like the msd tach driver for my car. this is not a plug for anyone, i thought it would be something useful for you guys. i posted the name of the user, i'd redirect your questions to him.

as for bringing the "device" somewhere to tune it, in the Pm i recieved he stated he needed to bring his car, equiped with a greddy emanage to an authorized dealer to tune.

 

What I wanna know is if by using the RPM adapter can we use a SAFC to tune this car?

 

emanage is a totally different system then this..... this is why i dont get that post....

 

i sent alpha a PM and hopefully he will contact me on aim, my aim SN is the same as my forum name, italstalnprd86 IM and i'll send you the links i have

 

my aim is the same as here as well..... i will get a hold of you tommorow

 

so with the greddy rpm adapter the safc should work. has anyone tried this yet? im very intrested in finding out for a buddy of mine.

 

i'm interested in finding out for myself.....anyone?

 

havnt heard from fsr yet...... i would assume with a tach adapter, and wiring it directly to the fuel, bypassing the factory set thing, or something like that, that it would work....... i dont know though

 

i'm waiting for your IM italstal. I talked to alpha already and he's not sure if it will work, i sent him the link from the other cobalt site with the info. I'm just trying to help. But i explained it to him like this. we couldnt just wire the SAFC2 directly onto the SRT either, we needed an MSD tach driver to get a clean signal. This gentlemen from the other forum, he's using a greddy type 1 rpm adapter (i'd assume its a tach driver wiht a different name) to get a good RPM signal. Someone on here needs to be the test mule and see if it actually works.

 

id do it..... accept i dont have the money.... parts for your car said they do sponsorships only if your part of a group, and then the group submits the proposal..... they have the apexi unit though, as that is where i saw it...... if i was part of a car club, i would go ahead and try to get one, as the test dummy......

 

My bet is the Apexi S-AFC II could work on the Cobalt SS if you fool the MAP2 signal (MAP AFTER the supercharger), not the MAP1 (before the supercharger) neither the MAF signal. You will also need a RPM adapter. You could try also a Split Second PSC1 fuel controller.

you guys have two map sensors and a maf? Strange.

 

Yes a SCIP (MAP1) which reads the supercharger inlet pressure and a MAP2 (pressure in the manifold; after the blower) + a MAF sensor.

Again the MAF and the SCIP and the TPS (1 and 2) are tightly verified by the PCM, but we should have more success (and way more efficiency) with the MAP2 sensor, which affect the timing and air fuel ratio.

Hey guys who will try first the RPM adapter and the Apexi S-AFC 2 to SCALE the pressure signal (not the MAF frequency) for the MAP2 sensor (the one after the blower) ?

I have the service manual shop, I can help to tell you which wires to tap !

jmc, pm me with details on this, is the apexi the best way to go, i have seen other options out there, and our a/f is a big problem....... i want to talk about this one...

 

I like the DTEC-FC but it won't work outta the box. However I think Rev-it-ups SMT6D is the best way to go for a "A/F controller" It's the got by far the best feature set.
