Hks Evc Iv/pro Boost Controler Help Please

Recommended Posts

There must be some Inhuman part man part hks computer on these forums who knows about the EVC IV/pro boost controler.

I found the manual for the setup of the EVC IV pro boost controler and ill attach them here


Page 54 is my boost controler if a picture helps. = http://www.hksusa.com/content/pdf1580.pdf

Does any one know what the 4 dip switches do on the back with any sort of detail at all please people.

We had a try and teaching it to learn the boost curve with no luck as of yet.But my tunner wishes to know what the 4 dip switches do on the back of the unit.

IF any one at all can help me please feel free to throw up some insight on this type of boost controler.

Some pictures of my unit.

Wow no body has one of these?

Or has any idea what the switches do on the back?

I like this unit id just like to get it to work god damn it.

I have spent the last 2 days looking for infomation about this unit i found install and set up but nothing has any info on the switches on the back. I know what the po and sw switch is the the small bank of 4 has got me stuffed and im wondering if thats whats causing it to over boost past one bar after it was set up.

the dip switches on the back are to set internal or external wastegate mode

and also from memory are used as part of the hks link system which is what the rj12 socket next to it is for

so check the manual, it should show you how to set internal or external gate via the dip switches

then self learn when did mine was easy

you turn on the self learn mode

it shows -3-

then you take off in 3rd gear and redline it

then it shows -2-

do the same in 3rd gear

and then it shows -1-

do the same

then its complete and self learn is done

you take off in 3rd so it has time to learn the boost build ramp

The sw/po switch sets external vs internal gate, the dip switches are a new one to me though and I can't help.

Looked at all my notes and came up blank sorry.

I have a IV, but not the IV pro, the IV doesn't have the dip switches. Mine is LCD as well, otherwise the units are pretty much the same.

If they are wrong in any way its not going to work lol.

As for the internal gate and external gate that is the PO/SW switch on the back.The 4 dip switch is something else ,.........

Thats the problem im running into heh.

    • New R34 owned here (from the US) and found a gem, '98 GTT with ~6k miles, super clean & completely stock. When shifting there's no grinding, shifts smooth, etc. The concern I have are 2 things: 1) Only in 2nd and 3rd... when maintaining a slower speed (in traffic as an example) as I let off/on the gas, the shifter will slightly move and vibrate. If the clutch is engaged, none of this happens. It's not bad, but enough to feel like something isn't necessarily right. 2) This mainly happen in 4th or 5th... the shifter slightly bounces up and down, almost like it's riding on unbalanced tires (and I do think the tires are unbalanced as I get a little of that bounce feel at higher speeds, which is maybe why it only happens in 4th/5th). Lastly, and sorry for this noob question but I want to work on this car myself, can someone teach me some on these manual transmissions? Like servicing them, best products to use, etc.; would be greatly appreciated. Thanks!!
    • Coilovers aren't even the first step. Bushes, subframe position and alignment, HICAS elimination, adjustable upper arms and traction arms in order to dial out understeer. All these things need/deserve attention first. ARBs (There's no such thing as a swaybar. Please, everybody, stop calling them that) are useful if you want to limit spring stiffness. Otherwise you can control body roll with springs. Spring and damper rates are a function of road surface, speed and usage. There is no solution that works for all cases.
    • Define "nothing". Is the starter spinning but not the engine? Engine turning but not firing? If the engine is turning but not firing, then you are missing either fuel or spark. You need to find whichever has gone missing.
    • Shitbox Tiguan updates, got the APR OTS tune put back on (no charge for it to be removed/added back), didn't want to just come in just for that (not a fan of wasting people's time for nothing) so I purchased an APR dog bone insert. The boys at German Performance Garage said they would fit it for free too since they had 1x hoist free. Now that's service you don't normally get from most workshops. Anyhow, tune back on, snow grate pulled out, dog bone insert back in and not going to lie, a few smiles when I nailed it around the industrial area heading back onto the M7. Amayama also said 1 to 2.5 month wait for the RB25DE heater hose, yeah why not, car has been off the road for nearly 3, what's a other 2.5?
    • Hmm I'm going to approach this from the other side... What is the car doing that you don't like or what would you like the car to do that is currently isn't doing (handling wise that is)
