Help on APEXi AVC-R

I brought a R33 4 weeks ago with a AVC-R fitted. The car was tuned in Sydney by a tuning shop with the setting ; A@8psi, B@10psi.

The car has been great, goes well etc, but a week ago when I turned on either one of these settings then place the car under load I now hear this ticking sound from where the ECU is situated(in front of the passenger's feet). It's like a relay clicking on & off.

Secondly, is it a standard for the display unit itself, when turned on to retain a lot of heat? When I touch the back of the unit, it seams to hold a fair amount of heat. Is this common with this system?

Any help on this is much appreciated

They are pretty quiet compared to other ebc's. I am hoping that the ticking noise is just the valve for the ebc, mine is located in the engine bay, they make the noise when you start boosting. The screens are really hot that's normal.

The AVC-R Boost Control Solenoid is usually mounted inside the engine bay. The ticking noise is normal when booost comes in. You can make this noise less noticeable by placing a flat rubber strip around 3 to 5mm thick at the base of the solenoid to cushion it from wherever it is mounted. I have made an mounting platform like an "L braket" out of 5mm aluminium strip to mount the solenoid properly, again with rubber cushion between mounting platform and solenoid for to recude the noise. This method also extends the life of the solenoid.

Heat from AVC-R control screen is normal.

If you require any further assistance regarding the above please contact me. Oh I sell APEXI products too so call me if you need anything.

Cheers!

Thanks for the advice. It's always a sigh of relief when here good news that all is fine. I had a closer inspection of the manual & found the heat periameters for the display unit.

I'm looking at upping the boost soon a few pound. I'm after 260rkw from which I'm told is quite easy with my current set up. I'm having it sorted through a shop to avoid any expensive mishaps, fuel rate being the key factor.

I will be looking at the apexi monitor which has rpm cutout & km/h in the next few months. If you have a price on this, let me know

Thanks again

      to fix the voltage drop issue I swapped out the old 150amp alternator which turns out is a brand known for having issues and replaced it with the black 180amp alternator beside it

      A31 Digital Climate Control

      By S1_C34 · Posted

      For anyone interested, the Way Back Machine has that Japanese website archived with pictures, etc: https://web.archive.org/web/20051023225805fw_/http://www.a31cefiro.com/air_con.htm "Simply swapping the wiring of the harness will not allow it to function properly. For the outdoor air sensor and sunlight sensor, disconnect the wiring connected to CN1-11 of the air conditioning harness from the harness and connect the sensor side wiring to earth. For the indoor air sensor, disconnect the wiring connected to CN2-3 of the air conditioning harness from the harness and connect the sensor side wiring to earth. The connector PIN numbers listed here are the genuine A31 PIN numbers. To avoid incorrect wiring, check with a tester before wiring. Also, disconnect the wiring in a location close to the sensor. The disconnected harness side wiring will not be used, so be sure to insulate it." Wish someone sold a conversion harness to just plug-and-play a Kouki 180sx digital climate control into C33/A31. I'm decent with wiring but feeling kinda lazy about taking this on. Edit: Did some more digging and found a helpful Minkara blog post about the conversion as well: https://minkara.carview.co.jp/userid/1831116/car/1360568/2284209/note.aspx "After installation is complete or the battery is replaced, you need to go into self-diagnosis mode and set the internal air recirculation. The way to do it is to "hold OFF with the key on for more than 5 seconds, set the number to 5, then press 卍→C." ↑↑↑It probably won't make sense unless you actually try it (・∀・)." Lol wtf

      PRP RB26 cast block + head prototype running

      By GTSBoy · Posted

      Well, yeah, the RB26 is definitely that far off the mark. From a pure technology point of view it is closer to the engines of the 60s than it is to the engines of the last 10 years. There is absolutely nothing special about an RB26 that wasn't present in engines going all the way back to the 60s, except probably the four valve head. The bottom end is just bog standard Japanese stuff. The head is nothing special. Celicas in the 70s were the same thing, in 4cyl 2 valve form. The ITBs are nothing special when you consider that the same Celicas had twin Solexes on them, and so had throttle plates in the exact same place. There's no variable valve timing, no variable inlet manifold, which even other RBs had either before the 26 came out or shortly afterward. The ECU is pretty rude and crude. The only things it has going for it are that the physical structure was pretty bloody tough for a mass produced engine, the twin-turbos and ITBs made for a bit of uniqueness against the competition (and even Toyota were ahead on the twin turbs thing, weren't they?) and the electronic controls and measuring devices (ie, AFMs, CAS, etc) were good enough to make it run well. Oh, and it sounds better than almost anything else, ever. The VR38 is absolutely halfway between the RB generation and the current generation, so it definitely has a massive increase in the sophistication of the electronics, allowing for a lot more dynamic optimisation of mapping. Then there's things like metal treatments and other coatings on things, adoption of variable cam stuff, and a bunch of other little improvements that mean it has to be a better thing than the RB26. But I otherwise agree with you that it is approximately the same thing as a 26. But, skip forward another 10 years from that engine and then the things that I mentioned in previous post come out to play. High compression, massively sophisticated computers, direct injection, clever measuring sensors, etc etc. They are the real difference between trying to make big power with a 26 and trying to make big power with a S/B50/54 (or whatever the preferred BMW engine of the week is).
