With the help of Allen (2LV8ETR), we chucked in my new (2nd hand) HKS EVC3 boost controller and it seems to be working fine. However I am having a few problems setting it up, does anyone have any experience with this unit? Anybody willing to help a brother out?

1 tell us what model it is . or post a link to a picture os a similar one . or at least try to describe it

2 do a search . ALL of the original instructions are on the hks website

3 how can it seem to work fine if you have no idea how to use it ?

1. As I said in the initial post its an HKS EVC3.

2. I have instructions however I cannot follow all the instructions.

3. All the buttons are working and it is able to read my boost levels but i am having trouble putting it into learn mode and setting my new desired boost levels.

you cant add a boost controller into a R34 (rb25det Neo) without changing the computer. The stock computer doesnt allow it as I was told ages ago from some workshops. Well you can add one in but it wont do shit, wont adjust boost levels like what yours is doing now...so new computer it is

Seems odd. Rob (don't know his username on here) has a black R34 with a manual boost controller and his is working running a stock computer. And those running Nistune still have their stock ECU's yet I have heard many have boosted them up. From what I've read you can add a boost controller however the ECU will just not allow you to run to large of pressures in them. Not calling b/s but my research has told me otherwise.

So very, VERY frustrating, argh! 5psi sucks!

i'm not 100% sure about this. if you remove the stock boost controller. and just hook up your aftermarket ebc how will the stock ecu stop it from increase the boost.

I know it will to the typically add more fuel but i don't see how it can stop your from increasing the boost

The OEM 2-stage boost controller is controlled by the ECU. You take the OEM unit out of the loop and install the EVC to the wastegate actuator and the ECU no longer has control over the boost levels. The EVC then takes control of the boost duties.

Once installed and switched on for the first time, the EVC is supposed to display a green highlighted "3" which depicts learning mode. It never went to that function. Trying to get it in learn mode was unsuccessful.

The issue is in the setting up of the unit, nothing else.

i am unfamiliar with the hks unit, but is it possible to set it up without using the learn mode. just setting up the duty cycle, gain etc

as my friends (Sean from Allstars and Ant from X-Speed) told me that with r34 you can't add a boost controller and turn it up like an r33 or 32 as the neo computer is designed differently, as viet_boi has said he is correct about the computer is the thing in the way that wont let you turn up the boost.

Nistune remaps the stock ecu...if your wanting to turn it up then i guess you'll need a updated computer (Apexi, Nistune, Vipec etc)

xx :D

It is meant to be. There is a manual learning mode where you are meant to dial in the stock boost however this function didn't seem to work properly either, it seems the stock boost level was a lower number then what the unit would allow me to dial in  :ninja:

again don't see how the ecu can stop you from turning up boost if you remove the stock boost controller and connect the ebc directly to the turbo wastegate actuator. then the ebc is controlling things.

Thanks man. I've got the instructions, they are just not being very helpful. I called JPC today to see if he might have any ideas or want to give it a shot and try, they didn't want anything to do to it! :banana:

Anybody living NOR and in the know wanna give me hand? I'm a nice guy! :) I tentatively booked it in with my mechanic on Wednesday to take a peak at it but like his Motech ECU's, he's expensive!

i try and look into it for you later tonight. i have setup a few ebc for myself and mates so i might be able to get something working but no promises :banana:

I've tried going into manual mode but it says I have to put in my OEM boost level first which I couldn't be able to do, it wouldn't go low enough.

Perhaps I can reset the unit?

    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment.
