Evc 5 Boost Controller Settings.!

[Stagea Denmark]

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 ).
