seems to me the ebc isnt doing its job properly, I experinced a similar probelm with my blitz EBC and probelm was the hoses running to the solonoid where to long so now i have ones that are about 15 to 20 cm and its fine, somewhere in the manual it says about making sure the hoses arent to long

Dont you mean too low?

Gain usually aims to ramp boost on harder the higher the setting.

Do you have a printout? Ideally the boost curve should ramp up to 1.1 (if thats your desired level) and flat line across the graph.

If its not close to that the ebc hasnt been set up properly.

Would the EBC still do its job if there isn't enough preload on the wastegate actuator? As not all EBCs are at 0% duty cycle until close to full boost are they? They are ~10% for the ones I Googled, which would suggest this would not cover up for a wastegate with not enough preload. It is possible to bridge the hoses that go to the EBC to rule out the EBC and check the wastegate is it not?

Happy for someone with more experience to correct me.

to check the gate, take the vac line off the actuator and block it up, see when you reach your target boost, but make sure you back off when you do as it'll freeboost

if it comes on earlier than your ebc needs to be set up better. if not then try more preload if you can

Its not normal. Remove actuator and check the load on it. It needs to be pre-loaded 3mms above the wastegate arm. Once done it should be back to normal.

Also check air leaks and etc which also affects the turbo's responds.

The truth is that the EBC hoses are like 50cm for sure.. but is that the reason? I will try to rule that out.

Isnt there a Gain setting which opens the wastegate progressively early ? Sure that isnt set too high ?

It seems that the HKS EVC 5 does not have a gain setting, i've read the manual like 10 times and nothing, only set boost and scramble..

The preload i think it's correct, Stao i didn't touched the actuator, it is like you sended it.

The think is tha eventualy in the end it reaches the target boost(1 bar) but it does that at 6200rpm from what i've seen(i don't have a printout).

If there were any leaks i would have other problems too right? like missfiring or something?

Tomorow i will try to block the actuator and see if i will have 1 bar earlier.

So today i've shortened the length of the EBC hoses and it looks it is a lot better than before! It holds 0.85 in low revs instead of 0.7.

Also i found the MAF cables stripped and they were touching each other, fixed that and it went very lean.. :happy: idle it was like 16.9 AFR's and 12.5 at WOT.

    • There's a huge reason manufacturers are tuning in dead flat torque curves... Make them reliable (and more drive able)
    • What HVAC actuator is under the steering wheel? Do you mean on the RHS of the centre console, immediately to the left of your shin? If so, then yes, it is probably that one, because that is the mode door actuator, and from what I know, it's still a pain in the arse to replace. I don't know about whole dash out, but you certainly have to rip into the centre console section. I don't know if it's covered in the workshop manual, as I haven't spent much time looking at those parts of it. (and by "the workshop manual, I mean the R32 GTR one, which is the most comprehensive one we have, and it should be similar enough between that and later cars to serve as a guide).
    • ...oops. forgot the TCU end...
    • No I got mine from a friend that had fabricated one … but I had to fit it to my setup which was a hks turbo setup. His was a Garrett -7. So one of my turbos was not a flange for one side … then I had a leak in the welds I had to find a weld shut … in the end the setup was decent priced but I spent a lot to get it fitted. A couple companies I checked would make it but you’re talking 7-9k aud with titanium. No joke mine was 6-7k even second hand after I had to fit it in Hong Kong … labour is expensive here. 
    • I'd just like to restate that I don't think anyone here is actually hating I recently sold a car part to a guy who was building a forged auto R34, with MV stall and aiming at ~450kw. I told him that I'm him, from the future and to stop after it explodes once. I told him I knew he won't listen the first time, and that's fine. But if my predictions do come true - Change direction faster than I did. I also said it's probably no coincidence that the dyno plot of a reliable turbo engine starts to look a lot like a N/A motor. :p
