Apex'i S-AFC.... who's got one?

I just got mine in the mail today from Rallifan, pefect condition BTW!!

I want to know what other 7g'ers have one and if there are any tips or tricks that might help me with the install.
Is there an appropriate chart for air/fuel ratio I can look at or is it just plug and play?
How long will the install take? If it takes 5 hours then I'll wait until the weekend..
Should a pro tune it for me or can I do it myslef? I am pretty self reliant when it comes to the G obviously..

I bought it for my "summer project" this year (couldn't beat that price with a wiffle bat).... but I figure why not just hook it up now in the meantime. Will it even do anything for my N/A 64 as it stands now?

Ya know...

Wes

Guess not :?

Where the hell is Dean when you need him?!

I think Chip (fishboy) has one fitted

I have an S-AFC but the 1st gen one, however its pretty much useless until I gather the rest of the parts for my turbo. Right now all settings are at 0. And it took about 20 min to install, majority of that time was removing the kick covers to get to the ECU. The New AFC has a bunch more wires though.

chip doesn't have his on yet. uhm a good person to talk to is craig. i know he has an afc on his 7g. installation on an eclipse involves tapping 4 wires and cutting one. uhm but be warned though.an afc can be ur friend and ur enemy. i remember if im thinking str8, sum1 broke into his car, stole his shit and fucked with his afc.with his settings all fucked up he blew up his motor so maybe tuning by a pro could save u a few bucks. rre has more info on the afc on their website http://www.roadraceengineering.com/newafc.htm u might wanna just read thru it so ur a lil bit more familiar

All I can say is "Yikes!"

I did talk to Chip via PM and he's getting his pro installed due to the complexity of the unit. Unfortunatly, I don't really have that luxary as there is no one in this town certified to install it, or anthing else really.

What can I say, I live in a town ruled by 4x4, Edelbrock loving, moose huntin', gun rack tottin' hillbilly's. :roll:

So I am going to do it myself, but not yet. I think I'm gonna hold off for a while until I can gather enough info to feel confident. That link helps a lot Allen, thanks.

Its REALLY simple to install. Your just tapping wires, and one wire you clip. I dont think they can make anything easier to install then an AFC. The only pain in the ass is working with the wires in the footwell..your back will be killin you.

Also, no point in putting it in now. You have to tune and adjust everytime the weather changes like 5-10 degrees, just wait till you plan on putting in the larger injectors and such.

Not worth the pain now.

You can install it yourself. I personally had problems with the wires because my ecu is different from the one on the diagram. But after checking EVERY SINGLE wire on my ECU I figured everything out.

I don't know about the weather changes though...how they can affect the setting on your SAFC. Because temperature inside the motor if pretty much the same...if it's 10 degrees cooler then the air that's coming in will be a little cooler, thus denser, and denser air means more HP. But yu are not getting more air...you're just getting cooler air.

My friend has stand-alone in his car, and he doesn't adjust it for every weather change.

As for tuning of your SAFC...you can tell when the motor is running lean or rich, just by the sound of the motor, and by the rpm. I would suggest waiting until you have more performance stuff installed. Then you NEED to go to the Dyno lab and do at least 3 runs (100 bucks or so). With proper tuning you can get every HP with SAFC, this HP increase can be seen only on the Dyno. Testing things out on the street won't do you any good.

Thanks guys, I had the feeling it was not gonna do me any good....... yet https://www.thegalantcenter.org/styl...lt/biggrin.gif

I am probably going to install it in the TSi for now, I know that engine forwards and backwards aleady. When my summer project for the Galant is done, then it will go in there..... and the wife can by an AFC for the TSi herself!

The install is not very hard if you have any knowledge of electrical wiring...soldering,splicing, etc.
It took me about an hour and 15 min. cuz I didn't have the correct pinouts till I was almost done.
DEFINETLY have it tuned on a chassis dyno before you mess with it yourself.
Also it is recommended to have it re-tuned if you add another major engine mod after its installed.
I adjusted my safc for the weather change in the winter...but I leave it pretty much the rest of the year round. It's not really needed to adjust it every 5-10 degrees.

Well damn, now Pavel and Joe are changing my mind.

Both of you guys said you ran into a problem at the pin out on the ECU.. can either of you remember the difference between what's in the diagram and what's actually there?

I can hook it up and not mess with it yet right? Is there anyway to just get it to display without actually changing any A/F ratio's? Like for RPM, cause my guages are off slightly...

First you have to look at the diagram that matches your ecu pinouts.

Most of the wires match, accept for the trottle wire I think. I can check all the wires for you most likely today and make a little tutorial telling which wire goes where.

The main problem i ran into was the air flow wire (the one you have to cut). I was using wires made for a pressure sensor instead of Karman sensor...and mitsu galants use Karman https://www.thegalantcenter.org/styl...lt/biggrin.gif

So sit tight...the tutorial is on the way.

I'll owe ya big time Pavel, thanks man!

The pinouts are different because 94/95 ECU's are different I think.

If somebody could back me up on that statement cuz I hate making guesses, but I know I read it somewhere.

Also, the s-afc has presets, so you can save it so that when the temperature rises, you don't have to re-tune, just go to another preset

</div>

Crap, so my 98 pinout might be different than Pavel's? Can anyone confirm this?

Also Jip said that the ECU is in the kick panel and other's say it's behind the stereo harness, which is it?

Pavel can't wait for the tutorial.

The kick panel area is underneeth and behind the radio. on the center console. Seriously people need to buy a manual before doing anything. Chiltons is a mere 15 bucks and you wont have to post up "where is this where is that"

As for the ecu, well I have a 97 dont know what you have but the wiring for my car is pretty much the same sa the eclipse 2g ecu which thepinouts are on dsm vfaqs..the differences have been posted here:

DSM Vfaq: http://www.vfaq.com/FAQlocator-index.html

I didnt solder anything, took me about 20 min. Already knew where everything was, just had to atatch the wires.

I have a Chilton's thank you, and believe it or not... I know a shitload about my 98 ES. Generally when you say "kickpanel" your reffering to the area around the dead pedal and fuse box, I just wanted clarification on this as the 94-96 differ in minor ways to the 97/98. I posted this topic, I'll ask whatever the hell I want.

That link helps a lot, thanks. :wink:

lol i like how you yell and then say thanks alot https://www.thegalantcenter.org/styl...lt/biggrin.gif

No prob. I meant everyone in general should own the manual for their car its like one of the best tools you could have, and if you plan to do any mods etc...its something that you absolutely have to have.

Actually Chiltosn's manual really sucks for some of their diagrams. They are off by quiet a bit. But they do tell you where ECU is located though https://www.thegalantcenter.org/styl...ault/laugh.gif

Jip you are partially correct about the ecu pinouts. But you have tyo remember that mitsubishi did a realy dumb thing...they changed ECu and wiring harnesses for their 96+ galants. In the 96+ galant the ECU has the same plugs as the one on 4g63 ECU, that's why it's much easier to do an engine swap in those cars.

My tutorial is for 94-95 Galants ONLY. (or at least for galant's who's ecu is different from eclipses')
>Step 1: Disconnect the battery by removing the negative (ground) wire
>Step 2: Locate the ECU. It is rignt behind the stereo, and underneath the transmition ECU. Best place to get to is is from passenger side.
>Step 3: Remove the ECU from it's stock location. You will need a 10 and a 12mm socket wrench. Usually it helps if you pull all of the wiring out as far as you can.
>Step 4: Locate and connect the following wires...
S-AFC wires ECU wires
Orange-----------white/black
Pink---------------white black (ecu side, check manual for more info)
Green-------------brown/green
Red----------------red (very thick wire)
Black--------------black (right next to red)
Grey---------------green/white
>Step 5: Attach the negative wire back to the battery and start the car. It will have a very low and unstable idle for a day or so (ecu's memory was erased, so it needs time to adapt to the car). Your SAFC should turn on.
>Step 6: Pull out the manual for SAFC and get everything setup. Here are few things to look for:
----Throttle, make sure it shows how much throttle you give it
----RPM, they will be off by a little bit, but that's OK
----Air-flow, when the car is idling it should say +/-35Hz ( :!: Don't forget to change the sensor type to Karman :!: )
>Step 7: Don't richen the car too much or lean it out too much if you have nothing done to the car.
With intake and exhaust I leaned it out by about 4% max at about 4K+RPM, at 1K it's at 0%, at 1.5K it's at 1%, at 2 it's 2%, at 3 it's 3%. This is my low throttle setting.
At high throttle i richened it up a bit between 1K and 4K, after that I leaned it out to about 4%. Becuse our car run really rich at high RPM at high throttle.
>Step 8: There's none! You are done https://www.thegalantcenter.org/styl...lt/biggrin.gif

Well done Pavel, well done. It doesn't help me and my 98 but well done https://www.thegalantcenter.org/styl...ault/laugh.gif

So then... my ECU pin outs are identical to the 4g63 then, or is the diagram that Jip gave me the appropriate schematic?

BTW, my S-AFC manuals are all in Chinese. I know the English version is on the Apex'i website but I have no printer right now :roll:

ummm
your pinout should *not* be the same As the eclipse

similar, but not Identicle (unless I'm really wrong?)


if you can get me a Copy of the s-afc wiring, I can get it for you for the galant

(what year are you? 95?)

well.. I have 96+ info here....

Wait now im confused also lol... And yes Ive found quite a few errors in chiltons.

Ok Pav. said the 96+ galants ecu changed and have the same connectors as the 4g63...he has a 98 so he should still have the same connectors and pin numbers as the one in the diagram..and he should have basically the same ecu that I do in my 97. Yes/no?

And well the wiring isnt exactly the same as the eclipse but the vast majority of it is. There are like 5 extra wires/missing wires, we dont have coilpacks so we dont have both outputs for ignition, etc.. Thats why I sent the link from Barnone (Craig werent you the one who give the ecu differences to Kim? someone on 4g64group did) Anyway the wires you need for the AFC are the same.

Im actually looking through junkyards for an Eclipse Spyder ECU and going to swap to get rid of this damn distributer. When I do that..I'll let you know the differences in wiring.

No no no JIP https://www.thegalantcenter.org/styl...lt/biggrin.gif , the pinouts are not the same. Only the plugs (the plastic part) are the same. So the diagram you showed is the correct one for 96+ models, and mine is correct for 94-95 models.
I hope this makes sense https://www.thegalantcenter.org/styl...ault/laugh.gif

You can call me Rob https://www.thegalantcenter.org/styl...ault/smile.gif

I understood that but he has a 98 so I gave him the right diagrams .. I think.

Also...According to the diagrams and the excel sheet, pin 58 is ignition signal (tach) Well...thats one of the differences between Eclipse and Galant, our Tach signal wire is pin 31 NOT 58.

And I actually just pulled my afc out today. I think its been f*ckin with me.

don't u just hate mitsu for changing the harnesses like that :evil:
What was happening to your SAFC? Did it make your Engine Check light come on?

No check engine light. Now I have the 1st gen afc, nothing fancy at all like the new ones, I have 5 dials for 5 rpm ranges to tune +-30% and thats it. The afc inputs are only the MAS, Tach.

I normally have every set to 0 since I have no real mods on the car other CAI for now. But you know when I turn any rpm range dial to richen up, my A/F gauge usualy does show the mixture richeneda little more. With everything set to 0 I was only like 1 notch into rich side, (no I dont have a digital readout gauge https://www.thegalantcenter.org/styl...efault/sad.gif ) and basically just screwing around in an open lot, I turned the dial up for rpm ranges just a notch or two and got no response from according to my A/F gauge. Just idling in park I turned up the 800rpm range dial, and usaly A/F goes real rich, ecu goes into open loop mode, car idles like crap...well this didnt happen.

I been having a lot of issues with getting bad mpg and I dont know if its in my head or if its a problem cause everythign checks out fine. So whatever I dont need the afc now, so I pulled it thinking its probly screwin with something, my car is running a little richer at full throttle now like I'd like it to be.

And I cant find my MAP sensor either! The pin on my ECU doesnt even exist, thats really bothering me..I posted a topic on that in general forum if someone would like to answer https://www.thegalantcenter.org/styl...ault/smile.gif

I had an issue with the MAP sensor as well...I did find the answer though https://www.thegalantcenter.org/styl...lt/biggrin.gif
We have MAF instead of MAP sensor. Older galants I guess did have that sensor on top of the intake manifold (picture in chilton's manual). So don't worry about that.

My car is running kind of funny too. At idle the RPM is really low. Sometimes it goes down to about 600 on the tach. But my SAFC tells me that it's at 700RPM. Other than that...the car runs fine with the safc.
