So ya, if anyone like knows anything about wiring, or has any experience with S-AFC's and ITC's, I guess i'd like a hand installing them sometime soon... I figure I might as well, since I have them, and like they aparently arent THAT hard to install (8 wires it seems?) but hey, I know like _ that much about wiring Mechanical stuff I can figure out, wiring, its like uhhh...

Anyhow, yes im getting ready for all the turbo stuff, and I dont have to do this like right now. Saturday at the soonest, but I think I need a 5v sensor before I do the S-AFC mod (so I can read boost rather than TPS, which aparently is a useful mod with the S-AFC from what the other EJ18 guys are telling me)

I do plan on doing this all in one day, maybe two at the most, since otherwise i'd have to borrow a car to go to work and I dont plan on doing that until I have to do the serious stuff for the turbo kit.

So uh ya, any help would be apreciated

 

I'm actually looking at installing my AFC... I've just been hesitating because I'm lazy I guess. What ITC do you have (apexi)? The AFC should be cake to install, like less than 1 hour (just a few vampire clips and one or two splices). Depending on what sort of ITC you have, that could take a while. Are you also going to be using a J&S at all? I have one of the version 2 J&S ultra safeguards, which tap into the ECU, so I think that should be pretty quick as well. If nothing else, let me know how it goes!

Edit: I talked to Scott (aka StankFootz) today telling him about my soon to be turbo ambitions and he mentioned your project. I've been watching your threads in the forced air forum at nasioc. Yay for us local guys

Oh, ya, both Apex-i models, older models too not new ones, got them used...

As for J&S, no need since my motor doesnt even have a knock sensor. Ill have an EGT and boost gauge for the bear minimum of gauges, and an rrfpr as well for fuel pressue, and my motor is so freakin cheap to replace who cares if it pops

Oh, and ive never spliced a wire before, and have no idea what vampire clips are... (no, im not over my head, i just dont know anything about wiring! Everything else im just about up to speed on, but that is what this is all about for me and what my car is to me really, one big learning tool )

 

Hey Kosta-

I don't think I knew what vampire clips were either till someone told me to use them for my AFC. they are these cool little things that you can use to tap one wire into another without cutting anything. As for the J&S, can't you still use one of those old J&S safeguards that have the actual knock sensor that you mount on your engine block to detect knocking (ala the one that is used in the scoobymods.com writeup), as oppose to the new ones that tap into the ECU, since your ECU doesn't have a knock sensor wire.

Im fairly certain im good for engine management, although i might need a oil gauge later down the line, but I cant really afford the J&S anyway...

BTW, I think I can do this next saturday!

 

Steve, I think this is the connector:

These work okay for interior connections but may allow corrosion to set in when exposed to the elements.

Yeah... those little connectors be them. You can get them at any auto parts store for a few bucks... they have all different types.

Can you replace the motor yourself or would you have to get it done for you. I guess that's all it depends on whether or not it's cheap

Just in case you would ever consider a J&S, I think the version 1 J&S units go for really cheap nowadays since everyone wants the version 2s that tap straight into the ECU. I'd still keep an eye out and maybe pick up a version 1 (with the actual knock sensor) if you ever see one

Edit: By the way, I was thinking of installing my AFC very soon also. I'll probably wait a few days till I get my J&S, or till I get a day where it isn't god awful cold... but do you know how similar the two ECUs are between our cars??

Edit2: That mod you mention in the first post, what is that about? Is that just useful for EJ18 peeps, or for everyone? It sounds interesting.

The ECU's are totally different

 

Vampire clips are the handiest things because you don't have to strip any wires. All you need are is a pair of pliers If you're worried about corrosion, put some dielectric grease at the connection.

 

Did you do your install? I did mine. Took about an hour. Not bad. Mostly just double checking to make sure I was working with the right wires. Only needed 5 or 6.

I am having a problem with it now though... I set all the AFC values to 0 and initialized it, and when I start my car it idles rough for a few seconds then dies.

jonathan

 

Really? Thats cool, only an hour. I have no idea what im doing though, and cant have my car dead. But if its that easy, I might as well try it out myself sometime with someone who knows something about wiring with me

As for the idle, try changing the first value and see what happens.

 

Ok, I got mine done. One of the connectors that I crimped for the MAF signal wire wasn't crimped right, and the car wasn't reading anything from the MAF, and was basically dying. Redid the connector and all is well. I can give you some tips now that I just did it. It really is very easy. What I did was went over all the install instruction I could find until I was confident exactly what to do, then I went and did it. Very easy once you figure it out exactly.

There are 7 wires from the AFC that you need to be concerned with, and 5 from the ECU. On the AFC side these wires can be spliced in with a vamprire clip:

red goes to power
green goes to RPM signal
brown goes to ground on the ECU side
black goes to ground on the other side. must be at least 1cm from brown wire.
Grey goes to

for the MAF signal, you need to cut the wire, strip off a bit from each side, and crimp a female connector on one side, and a male on the other. The yellow and white AFC wires, which already have male and female connectors on them will plug into these. The yellow AFC wire goes into the side of the MAF wire that goes into the ECU, and the white AFC wire plugs into the other side of the MAF signal wire.

Check scoobymods for its instructions. They are pretty much what I used, except that the wire numbers will be different for your ECY. You can check ravensblade's site for an ECU pinout and just find the wire that matches the ones mentioned, ground, power, RPM, etc. Also, check the AFC install book for a wiring pinout. My car was in there (diagram F1-b) so yours should too (F2-b?)

All you need for the install is vampire clips and some male/female connectors that look like the ones already on the end of the white and yellow AFC wires. To install a vampire clip, place two wires in the little case thing, and clamp the metal clip down with pliers, then close the cover. The male and female connectors are just crimped onto the ends of a wire that has been stripped back.

Message me if you need help.

I dont have the install book

No pics? Pics would like help emensely... Im just like staring here at the screen like

I think my lack of sleep isnt helping either... I need to sleep... zzzzzzz

 

You should solder the connections, not crimp them ...
