Re: Failsafe with HKS EVC 6
 

Update:

Found a cut in the path of the molex red, repaired and reassured connection to A8 ...

Water level light is Finally OFF!!!!!!! Happy day!

Confirmed by jumping the pump with the sys link ...

Niw the green led still didn't come one, and the thres amber is not coming on now too ... I tried the test idc jumper and the S led does flicker with throttle ..

Re: Failsafe with HKS EVC 6
 

first step is a success!

now the iDC signal.

I am afraid you have to retest all the test points again. This time, with the engine running.

Re: Failsafe with HKS EVC 6
 

Can you post a hi-res picture of the top side of the controller.

Re: Failsafe with HKS EVC 6
 

Post light fix diagnostic readout, Engine running idle:

Re: Failsafe with HKS EVC 6
 

Hi Richard, awaiting your input on the readings above, here is the picture you requested:

Re: Failsafe with HKS EVC 6
 

Took the car for a spin and its not acting right.

With the system of I get no boost at all, with it on only about 3-4psi and some flow bars before both yellow led's come on ... Think its in failsafe mode ... Is this due to the idc issue too?

For the time being, disable the failsafe by linking the "DFS" with "PRK"

Re: Failsafe with HKS EVC 6
 

Thanks for the update, it appears the test points are is now reading correctly. The controller is OK on all the basic functions.

Moving onto the next diagnostic work:

A few question first to help me:
1. When you do the SYS test, does the red and yellow led comes on on the controller.
2. SYS test: Did the system spray?
3. SYS test: Did the gauge show flow?

Next test for the green led:
4. Unplug the red and blue harness to stop the pump and FAV from activating.
5. Unplug the green harness.
6. Ground the green wire of the ECU harness (grey) and tell me if you all the leds come on on the controller.

Await your reply.

Re: Failsafe with HKS EVC 6
 

Link the "DSF" with "PRK" to disable the failsafe for the time being.

Re: Failsafe with HKS EVC 6
 

I went back in and disconnected the failsafe manually for now, if all goes well will deal with that, will test it later tonight if it boosts again ..

Answers:
1-yes both amber and red came on with the sys test
2- i disconnected the fav to purge the line and it did deliver to that end didnt test the jet end though, but the road test earlier it did show a few bars before fs kicked in ..

I did the ground test before when the system was malfunctioning and the green light sid not come on ...

Will try again and update

Re: Failsafe with HKS EVC 6
 

Richard,

Same result, when I grounded the green wire the amber and red lights came on, no green ..

What is causing the failsafe to kick in? System is receiving the idc signal clear from the voltage readings. Could it be triggered by an unsecured fav In the engine bay?

Re: Failsafe with HKS EVC 6
 

Until the system failsafe is set up, it will keep dropping the boost. We are no where near this stage. Need to sort out the green led and reading the IDC.

It appeared the green led failed. Lets move no, as it is not to important.

Let's set up the system:
(engine off, key on pre-crank position)

1. remove the two jets from the engine and let them spray into the air
2. SYS the system
3. Set the SC on the gauge until it to reads 6 bars
4. Set the WL to 10am
5. Set the WH to 2pm
6. Set the THRES to 10am on the controller.
7. Reinstate the jets
8. Remove DFS link back to PRK

Take the car for a test drive,

9. Hoe many bars are showing at WOT?
10. Does the failsafe trip and drop boost?

That is it for now. Await your results

Re: Failsafe with HKS EVC 6
 

Took her for a spin after removing the fs wires ... This is how it behaves ..

Will make your changes and report back

Re: Failsafe with HKS EVC 6
 

Looks pretty normal to me.

Re: Failsafe with HKS EVC 6
 

Can you check the soldering of the two components, it is to do with the green led.

Re: Failsafe with HKS EVC 6
 

I set the gauge dials as per my tuners's specs, all is ok now ... Just 1 Q, if I rewire the failsafe and choose to unlink the dhb it will not put the system under failsafe If I turn the gauge off, am I correct?

Dont really care about the green led, as long as the system runs fault free, that light will live its life buried behind a speaker ...

Would like to thank you for the great support you gave me ....

Re: Failsafe with HKS EVC 6
 

Yes, removing the DHB will allow you to retain full boost when you switch the system off. But I though you have already removed the failsafe wiring.

The settings I mentioned is just a starting point. If you rely on the meth tune, you need narrow the window by trimming the WL and WH. It is all in the user manual.

Have fun.

Re: Failsafe with HKS EVC 6
 

Hey Richard, I'm reviving this from the Dead :)

I'm now in the final stages of my setup (Finally) and i want to add the failsafe into the setup, I rely on the water injection to work in order to achieve the timing i have set, so in the event it stops working i need to make sure boost drops quick.

Reading through the diagram, i'm alittle confused, With the EVC6 and an external wastegate

O = Direct to Top port on EWG
I = Direct to Bottom port on EWG with "T" to Turbo/boost pipe

With the instructions earlier on, you saying when there is an issue the MAC valve will turn off and air will pass from the Turbo to "O" which goes to the TOP port on the EWG, but if pressure is applied from the TOP this will shut the gate cause boost to be uncontrollable. in the event of a failure, Ideally Zero air must flow to the top port and all must go to the bottom port force the gate to open at spring pressure.

Possibly i miss-read the diagram or instructions?

Would it be possible to do a diagram from this illustration (Attached) ?

I'm assuming you still keep a similar plumbing configuration but add the Mac valve in to bypass pressure in the event of an issue on the Aquamist unit.

Thanks!

Re: Failsafe with HKS EVC 6
 

Try this one....ignore the other connection, concentrate on the red, brown and white wires to the MAC valve.

Re: Failsafe with HKS EVC 6
 

Hey Richard

Just a question, for the HKS, how difficult would it be to swap the grounding option for the White wire?

So my theory is rather run the evc ground from the aquamist, in a failsafe it cuts ground thus turning the EVC off. this would force the car to run spring pressure.

Is this an option if i sent you my unit?

Thanks!

Re: Failsafe with HKS EVC 6
 

Brown, white and black are the contacts of the failsafe relay.

White = common
black = normally closed
brown = normally opened

Under the normal operating environment, aquamist keeps the failsafe energised until some goes wrong. This means brown and white are connected.

Re: Failsafe with HKS EVC 6
 

Oh dear! :s

Re: Failsafe with HKS EVC 6
 

Thanks,

So then my theory will work, run the EVC ground to the white wire, in normal operation it is grounded, when something goes wrong it is disconnected, thus turning the EVC off.

I'll wire this up as soon as i get a gap and let you know. this will be alot easier then using a mac valve in conjunction with the stepper.

Thanks
