Fitting my nice new and shiny, well dull silver, HKS EVC 4. What I need to know is what to set the low, high and scramble settings to. As I understand it, setting it too high will damage my engine or turbos? but how do I know what to set them to? Come on you advanced motoring engineers. Help required to get this right!

John, I have my HKS EVC IV set to .8 bar, 1 bar and 1.05 bar respectively. HKS intercoolers and iridium plugs on an otherwise standard engine and turbos.

 

-Andrew

How did you work out what your settings should be. Was it just trial and error on making the engine not pink/detonate or what? I make it that 0.8 bar = 11.6psi, 1.0 bar = 14.5, 1.05bar = 15.225 psi.

 

Mine has JWT Sport 500 Turbos, JWT ECU and Stillen 555 Injectors. I was going to try a setup of 1.0bar (14.5psi) as the "low" setting, a conservative 1.15bar (16.675psi)for the "high", and an optimistic 1.20bar/17.4psi or 1.25bar/18.125psi for 10seconds for the "scramble"?

Is this too high or not high enough?

John, the settings were made by the company that did the install for me - TDi. I've had no problems to date at these boost levels.

 

As a guide, Sport Compact Car's Project Z (April '98) used an HKS EVC 1 at 12, 14 and 17psi. The stock engine had similar mods to yours - JWT Sport 500 Turbos, JWT ECU and 440cc injectors plus Stillen ICs, twin POP air intake and B&B exhaust. Their car made 400 hp at the wheels.

John do you by any chance know how your ECU is mapped....i.e is the chip mapped taking into consideration the other mods you have or was the chip done first and the rest of the mods done after???

The exhaust and single Stillen pop charger were first and then I purchased a job lot from Stillen (turbos, injectors and ECU). Stillen said that the JWT ECU had been mapped to take into account that turbos and injectors were being upgraded at the same time. The only things that may not have been communicated to JWT for the re-mapping would be that the car is an automatic and that it was a UK car, so the fuel expected to eb used would probably be set to expect the 92RON (US) fuel rather than the 98+RON (Optimax) I mostly use in it.

John,SORRY i havn't got back to you about the settings i've had loadsa probs with my internet...missing posts and other more drastic stuff!!

 

With regards to the boost settings i think you got them just right....Maybe a touch too high on the low setting as you may want to have it set lower for being in the rain or whatever but that's up to you...

 

At the moment i have mine set on 1/2 bar for low and 1 bar high,but i can move that around as and when i want to with the boost controller i have and i can also change the way the boost comes in from mild to sharp which does make a difference too!!

 

Just to say that if you have forgewd pistons you can probably get away with a little more on the scramble as your ECU will compensate for any pinking/detonation at up to 1.3bar as you have the larger injectors too!!

 

Hope this helps

Ok had the thing fitted now. tried running the learning mode and got the -L- ok. I tried the second run for the -H- setting and no bleeping heard to say it was set? I have had to reset it a few times too. I have tried to follow the dumb instructions but I cannot get it right.The MODE button seems to change the settings options but I cannot work out where I am with it. I think that I finally got the settings in as Low = 0.95bar, High = 1.2bar, but cannot get to the stock, scramble or warning setting modes. Damn I hate technology. Also if I set it to low and give it some welly the boost goes from idle at -0.59/-0.60 through to 1.53bar, no warnings or cut outs? So what have done wrong? At this rate I am going to blow the engine or turbos the amount of pinking I think I can hear. Nice and fast though. I should have gone somewhere to have it setup.

Does the pinking you think you can hear sound like a pack of metallic cards being shuffled?

Yes I think so but to be honest as I have never heard an engine pink before I am guessing.

I would take it to a rolling road, and have someone to confirm it, and setup your controller properly, you don't want to hole a piston through detting.

I am currently trying to find a good/competent rolling road in the Midlands capable of handling over 350bhp at the wheel with little success. I have an offer from someone running an HKS EVC IV to do it for me at an airfield on 23rd, so hopefully that will resolve it. I still thinks it needs a good tuner to look after it now. Any ideas?

The best description I have heard for detonation as someone posted here once is it sounds like someone pouring a tin of small pebbles on the bonnet.

Until I heard it I was a bit worried myself whether things were set up right but it is quite easy to recognise when it happens.

 

John, due to the twin turbo setup on the 300 you will have major problems getting the auto calibration to work. The best and most reliable way is to set the unit up manually using These instuctions if you don't have them already.

 

If you need any more help with this then let me know...

 

CheerZ,

Thanks but these are the same instructions I got with the EVC. Every setting it says just says press the MOD button. eg. Warnign, Scramble, etc are all set by pushing the mod button. No saying what appears on the screen. Crappy piece of kit. Wish I had gone for an Apexi one now. Last time I buy HKS crap.

John, this link may help:

-Andrew

OK, now I am confused. The post from the TT.net says that the 300TT has an "internal wastegate" but when I spoke to Jeff from Zedworld he suggested that it has an "external wastegate" so I set the HKS EVC switch to PO? Which is correct? This may be the reason I can't get it to setup.

John, stock turbos are internal wastegate. The actuator is external. According to the SCC article your JWT Sport 500 Turbos can be supplied with either single or dual port actuator. Take a look at the diagrams in the EVC install/setup. The actuator will have either one or two hose connections.

 

-Andrew

Andrew. I have spoken to the machanic who installed the both the turbos and the boost controller and he said that the actuator had a single pipe. He installed it for an external wastegate and single port actuator. Is this correct as it goes against the HKS setup options? They say either Internal wastegate/Single port actuator or external/dual port actuator.

When HKS refer to external wastegate they are refering to one of these types: www.machv.com/exwasforract.html (ie exhaust gas venting). Do you have these? If not go for Internal wastegate/Single port actuator "SW" setting.
