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?

:)

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

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)

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'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?

      This isn't for lotsa powers, and time and effort isn't even a thing I'm concerned about The whole reason is "Just because fun", and "Just because fun" is what I do And whilst there are other kits, with better and more modern turbos (Rev9 use the same Kraken manifold I believe.....EDIT... nope, the Kraken is a cast jobbie, the REv9 uses welded up stainless, plus $8000 AUD before shipping, installation and tuning) Where else in Sydney can I do a drive in drive out with the after sales support that MX5 Mania give My Turbo 86 made around 200kwatw on a AVO turbo kit that Pulse fitted, and it was over 100kg heavier than the MX5, but it was a blast to drive around the streets, until I crashed it.....DOOH, so somewhere around 200 ish level and some whooshy noises and I'll be happy driving to work, the shops, or heading into the country with Jackie for Devonshire tea So, thanks Dose for your info, it sounds like a 0.64 will be fine for what I'm after👍 The only real racing I do nowadays is to the toilet

      I know you don't want to hear this comment, but I can't not say it.  I just can't see 200kw being worth the time and effort. Its like guys with NA cars, putting in headers/exhaust/tune for a massive 20% jump in power. Great, the slow car is still slow and you're down $10,000.  My vote is leave it NA or price in a gearbox upgrade and shoot for at least 300KW, preferably 350KW+.  Now you have a NC that will try to kill you from time to time and will be exciting to drive
