Hey Guys,

I have just started to install my avc-r boost controller and have found the vehicle specific wiring diagram obtained from the official apexi site does not match that of my ECU. My car is a 1995 series1 gts25t.

Below is the picture of the plug and where I was going to splice the wires at. (Note no rpm signal pin where it supposed to be)

Does anyone know what deal with this is or where the actual rpm pin is?

Also, have I got it upside down or the wrong diagram???

And here is the pin out diagram provided by apexi.

Any help much appreciated, as I'm baffled.

i just installed mine 2 days ago, that is the correct diagram and mine works . i highly suggest u got the the injection signal rather than the rpm since the avcr cant "self learn" the boost setting to the specific injection duty. (if u are setting it urself and not getting it tuned)

if u are getting it tuned let the tuner set it to ur revs, my mate told me he knows a guy who blew his engine because of that.

im gunna write up a DIY since no one here has done it for the avc-r. so it will be up soon

heres a diagram that would really help. u can double check if ur wiring is backwards by checking the blanks.

the diagram shows the male(pins) on the ecu. so make sure u dont get them mixed up.

like i say follow this diagram, the blanks will clearly show u which wires the the right ones. gluck dude and make sure the wires are in good contact.

no probs i was shitty myself too when i did it LOL.

but when i followed the connectors according to blanks i relise they are the male connectors.

have fun. ps u going for injector signal or rpm. i got stock turbo too so let me know how much duty cycle u running.

this is the way i set up mine.

OFF-stock boost (this way u actually have 2 boost settings)

A- .65 with 35% duty cycle (street)

B- .80 with 45% DC (dont want to hurt my baby).....this is enough fun for now.

It's now wired in, sh1t's rock'n an roll'n. I just went with the rpm signal as I'll have the pfc to monitor injector duty.

For now I'll be running a big 10% DC just to stablize the boost curve ie. not solely relying on wastegate (probably bump it up to 9psi) Untill I get the rest of mods on and a proper tune i'm not gunna bother running anymore boost.

ahhah pussy! ;)

i ran .85 as soon as i test drove it LOL, this is with my stock cooler.LOL

just finished putting on dump/front, catch can, r34 cooler,water spray for cooler and redo my boost gauge to pro standards. just need an exhaust place to weld up my hi flow and ill feel safe running .8bar (12psi)

just a quick question me that me and a mate had diff on. the smaller the duty cycle the faster it boost? or the higher it is the more it boost?

Bahaha...

I couldn't resist either, nice cool night minimal traffic. Boosted it up to .8bar no troubles. Looks friggin cool at night.

Na, the duty cycle is purely to do with boost control by controlling the duration the solenoid is open and bleeding off air. It has no effect on the rate of spooling, the higher the DC the more air is getting bleed off ie. tricking the wastegate actuator into running more boost.

    • It's excellent but I'm still breaking it in so I'm not 100% sure where it'll end up. I would say it's about 15% heavier than stock and the smoothness of the slip zone is quite progressive but you need to be a little patient compared to stock or it'll bite hard and stall. Stock I got away with absolutely horrid clutch control. Like I said before I couldn't even tell where the clutch would grab when it was stock so releasing way too quickly without enough revs it would just slip and the revs would drop lower than ideal but that would be the end of it. Currently there's a bit of a nasty clutch judder if I don't apply enough revs + find the exact wrong point of the slip point in the clutch pedal but it feels like it's slowly resolving as I drive it more. I would not recommend the competition clutch unless you really need the extra clamp force. I think this clutch combined with the Nismo operating cylinder is going to be exactly what I want. Enough bite that you need to remember the release point to avoid stalling or rough shifts, but progressive enough that it's not hard to drive by any means and not heavy at all. I tried a "super single" clutch on my friend's 997.2 Turbo 6MT and that was absolutely horrid. It runs an electrohydraulic power steering pump for the clutch power boost so there's zero feedback in the clutch pedal and there was a horrific clutch shudder well after break-in due to the lack of marcel springs or hub springs in the friction disk. It felt like the slip zone was the thickness of a single toe twitch as well so it was almost impossible to avoid stalling it unless you gave it a ton of revs and just dumped the clutch instead of trying to be smooth with it. I was terrified of pulling out in front of traffic. I have also tried some kind of "super single" on an EK9 and that makes this twin plate Coppermix look like a stock clutch. Releasing the clutch pedal even slightly too quickly feels like you're getting rear-ended. The pedal is extremely heavy as well and there's no vacuum assist like the GTR.
    • Yeah, well I was probably way underguessing the $300 figure anyway. Just multiplied a "normal" by 4 for the purposes of pointing out it's not cheap, particularly if it has to be repeated.
    • We have an alignment shop out here that does what you're talking about but he wants like 800 AUD a pop. DIY is "cheaper" but once you start accounting for the value of your time I'm not sure it's worth it.
    • The main catch phrase for any car is "the eye of the beholder", and "personal tastes and preferences" And as for the plastic "flares", I honestly think they look cheap and tacky, and I cannot see them aging well, maybe if they were body colour they might look better to my eyes, but, I would still prefer it the were more like the older WRX STI models that had the wider body metal panels In saying all this 5hit, I wouldn't buy a new WRX again, even if it had the wide body metal panels
