Hey guys, i have just installed the EVC 6 (the new one with color screen) and the unit showing no error when i set the target boost to 90kpa but i can only get right around 60kpa (stock boost value). I have tried reset everything and started from zero but still can't achieve the target boost. I have also tried to adjusting the offsets as described in the manual, verified the lines are correct and checked the waste gate type is correct.

I have been searching in other forum as well and said make sure to set the maximum standard boost setting to a value just below what the car makes on the waste gate spring after the EVC is installed. Tried this as well but didn't work :(

Any thoughts?

Cheers

JK

?????? An ebc can't lower your boost. If you have set you maximum boost below your wastegate pressure it isn't going to do anything.

Actually i have set the standard maximum boost at 58kpa and the target boost at 90kpa. Its stated in the manual that the abc will 'learn' from the car while achieving standard max boost and from that it will increasing the boost. Confusing.....

Hks evc doesn't lower the boost when it's set to "0". That's where you're meant to start anyways on top of the stock boost. i.e. set the evc to 0, then find the stock boost which he said 58kpa? then you set the evc to add additional 32kpa since his target boost is 90kpa.

what do you mean "max boost", I have EVC6 to ,not colour, and you have to set base boost at 58kpa and the EVC will work from there, if you have set "max boost" at 58kpa then it won't boost past that,

I set max boost at 150 on both cars just it case of spikes in lower gears

I found the "quick operating manual" for the evc6

1- on

2- pas (kpa)

3- S (internal gate)

4- max normal boost ( I see what you were saying now)

5- turn till the target kpa and set

6- offset (fine tuning for if the boost trails off up top)

If that is what you have done and the lines are round the right way and connected on the car correctly then i would say its broken, there is not much else that it could be.

how have you connected it into the car?

      What brakes on R34 GTT(Europe)

      By Kapr · Posted

      Yeah i found that alot of parts can be wrong or "very" hard to get the real right one. I already bought some brakes years ago on me "old" GT calipers and they were wrong too 😄  I told them too. Even send them pictures...but they said "EBC catalogue has them on my car... So i dont know what their answer will be. I call monday them and let them know that they are really not on my car. If they were they would be already on a car...

      Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.

      Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?

      Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.

      R34 Gtt Wheel Offset Advice

      By Kinkstaah · Posted

      This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
