Hi guys.

I have a HKS EVC-5 in my car, but i can't get it to work correct, no matter what i do.

Then i hope, there is guy here with the same booste-controller, and he can thell my how to do the settings.

When i set the boost on A to 0.6, it boost with 0.6 bars, when i try to boost higher, it goers directly to highest boost, something like 1.7 bars, my ECU stops this, when i goes higher then 0.75 bars, only to protect the engine.

The strange thing is, i only have to adjust buttom A a 1000/ of a millimeter, to go to maximum boost, why.!!

The EVC know i have external wastegate.

Engine RB25DET.

I have one of these on my rb26 stagea so will try to help.

I can send the instructions in english to you but will have to scan them first ( 7/8 pages) so will try to explain first

There are 2 settings A & B . These work as boost settings that are independantly set as amounts above the std setting..

Once set , and saved ion memory, you switch from a to b dependant on your choice or switch the evc off to go back to standard boost settings.

If you can set A then you can set b - just do the same procedure with button b (on set mode) and set to higher figure.

however it sounds like you have not set A at all - If you dont key in and accept the a setting it will default back to std boost (o.6) and i think thats whats occurred,

Its very easy to get the evc into dispaly setting mode where you think you are setting the boost but are actually setting the way the boost is displayed, (been there )

If this doea not help email me at [email protected] and I will send the instructions . But it will take a few days.

also I am in the UK so allow for the time difference

The evc5 is a fully electronic unit and works very well (when set up correct) but is more difficult to set than the std type of boost controllers

Thanks m8.

I found the manual on HKS-Usa's homepage i english, have read it, and try to adjust to boost on a.

On the display, i have 24% right now, and the same with the little turn-bottum, max at 40%, does this sound right.!

But i can't get it higher, it i chose to go to 30%, it just boost much higher, thats the problem.

Does not sound like the right way to set the boost . Are your instructions the full ones or the "quick install" one because the latter is not that clear.

If you set the boost higher than the ecu will allow as soon as it goes above the permitted level the ecu cuts out the evc5 and you go back onto std boost (0.6 )

The evc5 will not boost over the ecu maximum boost setting (if there is one ).

      I finally got it on the dyno today and luckily it stayed in one piece! It wasn't without its dramas though. First off, sent my power steering belt to the moon around the third pull. Scared me half to death. Tuner laughed and mentioned that often happens with RB's... I may need to look into adding the Ross power steering idler, or something a long those lines.  Second issue that came up was about 2 hours in, we realized the VCT wasn't working and had to go back through the timing and knock threshold once it was fixed (I had botched setting up VCT). That waisted a good hour or so. I was surprised to see that with VCT working, we saw a ~38rwkw difference across the powerband. More then I would of expected.  Without further ado, made 463rwkw@27psi. Not the numbers I originally set out after, but still more then enough to kill myself and I'm very happy. Mustang roller dyno's are known to be heart breakers compared to other dyno's. Two things that limited me, first was the hydraulic lifters/7600rpm cut. Tuner was adamant that I was losing out on a lot of power up top because of it. Second was the pump gas & WMI. He wasn't 100% comfortable tuning with WMI, and was honest about it. He stated he's more confident on E85/Race gas. I look at this as a positive as it leaves me a lot of room for improvement. All in all, very happy! I need to see what I can do about that rev limiter... I use to rev my stock RB20 to 8000rpm and now I have a fully built head that I only rev to 7600... It's bugging me.  Don't mind my fantastic picture/filming skills.  RB28 - Dyno (1).mp4

      What Is A Good Setting For Street Camber?

      By The Bogan · Posted

      The best setting for street is what gives the best tyres wear for your driving style Different tyres like different camber You want the whole surface of the tread to wear flat, if the inside of the tyre is wearing more than the outside reduce camber settings For toe, have the minimum amount to give the handling you want Caster, from my experience if you can adjust it, is as much as you can get without clearance issues And while -2.5° of camber on the front might work well with good tyres for "spirited" cornering, it may be too much for a street car Lots of front camber will effect braking Just like to much rear camber will effect rear traction (rwd), and braking  When I set my Bogan Cruise Ship (VX SS) up for drags I tested how much tyre width I actually had in the rear by doing a hard launch (skid), it originally had -1.5° in the rear, and you could see that the tyre wasn't putting down alot of the tread, I maxed out the settings to get as little camber as I could with the OEM adjustment and some camber bushings and got it down to just under -0.5° with 0 toe, that gave me a fair bit more "rubber on the road" and helped it hook up for my 60' and my 0-100kph And with -1.5° in the front the big old boat handles fine on the street and my tyre wear is nice and even on both front and rear tyres (currently Hankook RS4's) As for semi slicks at the track, again, it depends on alot more IRT the suspension, the track and lots of other things, so, I'll leave that up to people who have more experience, especially with a AWD In saying this, street settings are pretty easy, just look at the tyre wear Meh, Necro thread, it's late at night, and I has been drinking beer
