Tricky-Ricky Posted July 10, 2007 Share Posted July 10, 2007 Right AFAIK the HKS solenoid is marked B = 1 which goes to the plenum. I = 2 which goes to pressure reference source/turbo. O = 3 which goes to the actuator. Quote Link to comment Share on other sites More sharing options...

madmunky Posted July 12, 2007 Author Share Posted July 12, 2007 Done yesterday and cars working good now, get 0.8bar on the first turbo then set it to 1.1/1.2 on the second. Thanks again for everyones help Quote Link to comment Share on other sites More sharing options...

dwayne Posted July 12, 2007 Share Posted July 12, 2007 well done mate, i have been reading about the trouble you had with it. all worth it in the end i hope Quote Link to comment Share on other sites More sharing options...
madmunky Posted July 12, 2007 Author Share Posted July 12, 2007 Yes mate, cant believe it all now really car flys now and pulls like a train, done 170mph on my test strip and wasnt even pushing it just got me a little scared so slowed down as never been that fast before. Tried the car now in both Seq and Par mode and prefer Seq a lot more fun, in Par mode when both actuators are open it just makes the exhaust sound like its blowing not too keen on the noise.

Anees Posted December 18, 2008 Share Posted December 18, 2008 Right AFAIK the HKS solenoid is marked B = 1 which goes to the plenum. I = 2 which goes to pressure reference source/turbo. O = 3 which goes to the actuator. Maybe this will help more. I have been trying to install a HKS EVC5 to my Aristo and am confused. In the diagram it says O goes to the pressure reference source and I to the actuator, yet in the text (post 26) its the other way round? Any help appreciated? Also, basic question here, but if the Boost controller is only pumbed into the turbo at the front, how can it control overall boost? Surely with two turbos their are two actuators and two wastegates?

Tricky-Ricky Posted December 18, 2008 Share Posted December 18, 2008 Think you're reading it wrong, and getting confused, first off, its only the first turbo wastegate that controls the boost for both turbos, due to the way the sequential system works, so forget the pipework for the second, Both diagrams/lists are the same. I = is the reference source for the boost controller, which comes from the first turbo pressure side. O= goes to the first turbo actuator, there are two ports on this, one of which must be blocked off. B= is another reference for the boost controller from the plenum.

Anees Posted December 18, 2008 Share Posted December 18, 2008 Thanks Tricky Ricky. I get easily confused! LOL I shall try again, but I might have some more basic questions! Quote Link to comment Share on other sites More sharing options...
Anees Posted December 21, 2008 Share Posted December 21, 2008 Thanks for the help so far but something doesn't appear to be right I keep getting run away boost when the second turbo comes online and have hit as high as 20++psi before I noticed. The Boost controller is set to warn at 125KPa (1.25bar) and I wanted to have two boost settings 100Kpa (1bar) and 120KPa (1.2bar) but everytime I try and go for a run the car makes alot more boost I have taken some pics and of what I have done, could someone please take a look and see if they are correct. I am wondering if I have port O and I plumbed the wrong way round? http://www.ranatech.co.uk/aristo/hksboost1.jpg http://www.ranatech.co.uk/aristo/hksboost2.jpg http://www.ranatech.co.uk/aristo/hksboost3.jpg Can anyone spot what I have done wrong? Thanks, Anees Quote Link to comment Share on other sites More sharing options...
Steve Posted December 21, 2008 Share Posted December 21, 2008 Have you told the boost controller which way it is supposed to work? ie internal or external wastegate? Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted December 21, 2008 Share Posted December 21, 2008 I suspect you haven't blocked off the 2nd actuator feed, so it never opens the wategate when the boost controller would normally open it. Quote Link to comment Share on other sites More sharing options...
Anees Posted December 21, 2008 Share Posted December 21, 2008 Thanks for the replies. The Wastegate is set to SW (Internal Actuator) @Tricky-Ricky -mate, is the 2nd Actuator feed the pipe in the second picture I posted connected to the bottom of the actuator? If so, then that is capped off Quote Link to comment Share on other sites More sharing options...
Anees Posted December 21, 2008 Share Posted December 21, 2008 Just had a thought (Uh Ho ) http://www.ranatech.co.uk/aristo/hksboost4.jpg Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted December 21, 2008 Share Posted December 21, 2008 The wastegate actuator VSV needs to be caped, likewise the actuator hose, so you should be left with only two hoses, the other from the actuator and the reference from the turbo.

Anees Posted December 22, 2008 Share Posted December 22, 2008 (edited) Thanks for your patience mate!! This is the first time I have ever had a go at doing something like this! I will try and get some caps locally today and cap everything off properly. If I can't find any then would, adding a bit of silicone pipe with the end blocked off do the same thing? I was looking last night at Supra forums and found some with a really useful post where they had taken step by step pictures of their HKS EVC install. The thing is they had their Port O and Port I connected the oppositve way round to mine..

Tricky-Ricky Posted December 22, 2008 Share Posted December 22, 2008 All you need to cap the pipework is a short length of silicone tube and a good fitting bolt;), as for the connections, i pulled the orientation for them for a couple of sites, one of which was an old HKS boost controller diagram, but i guess its possible they have changed them.

Anees Posted December 22, 2008 Share Posted December 22, 2008 Boost Controller setup was halted today when I opened the bonnet and saw this: http://www.ranatech.co.uk/aristo/broken.jpg Nursed the car home again and today I decided that rather then get a stock part from Toyota I'd rather get some reinforced Silicone Hose to replace it. Decided on a 90 degree elbow reducer (76mm - 63mm), a 45 degree 63mm elbow and two aluminium metal hose joiners; oh and some jubilee clips and a super strong T-bolt clip. Excellent Service and help from Auto Performance Silicone in West Yorkshire Got home and compared to my standard part and started joining my pipes together: http://www.ranatech.co.uk/aristo/stock.jpg Cut them down: http://www.ranatech.co.uk/aristo/cutdown.jpg After some playing and tightening up the hoses I think it looks rather good and I have peice of mind that pipe aint going anywhere!!! http://www.ranatech.co.uk/aristo/fitted.jpg I also used some hair spray on the inside of the silicone hose (which is a tip I read about). Hopefully I never have problems with that pipe again!! Now to get this Boost Controller functioning properly! Anees Quote Link to comment Share on other sites More sharing options...
legendswraith Posted December 22, 2008 Share Posted December 22, 2008 http://www.componentforce.com/en/index.php?pagecode=productcategory&id=32 thats where i got my caps from anees, they provided me with some samples for work (ahem) as i couldn't find anywhere to get caps from locally Quote Link to comment Share on other sites More sharing options...

I tried every local motor factor (thats 5 including Halfrauds) for some caps and no one had anything I willl just use a bot in a piece of silicone pipe for now, but I'll order these to make everything neat once I know the boost controller is working properly.

Anees Posted December 23, 2008 Share Posted December 23, 2008 (edited) Still not working. /vbb/images/smilies/bbcode_sad.gif I am getting fed up with it all now! Today I made sure all my connections were neat and I capped things off alot better http://www.ranatech.co.uk/aristo/vsv1.jpg http://www.ranatech.co.uk/aristo/vsv2.jpg But no matter what I do the car still seems to overboost when the second turbo comes on. I have set both mode A and mode B to zero 0 which should be a 0% increase over the stock baseline boost setting but I still get very high boost. My car has one decat in and a 3" Catback exhaust, and before boost controller was installed boosted to about 0.9 - 1.0bar. I am beginning to think the boost controller is faulty; even if I change the hoses for Port O and I over, do a master reset the boost controller still doesn't hold boost. I also wanted to ask people that have a HKS EVC5 if the flashing red power button is normal when the controller is powered on? http://www.ranatech.co.uk/aristo/redlight.jpg Does it indicate a fault?? The manual also mentions adjusting the boost offset, which I am supposed to be able to get into by pressing MOD for more then 1 sec from the main screen so I enter the display settings mode and then press MOD again for more then 1 second. Everytime I do this the boost controller does not go into offset; it moves onto a different screen. Grrr!!!! I have read the manual and followed the steps it suggests with no success. I really don't want this controller to be faulty, because I have the screen nicely fitted inside my ash tray after hacking my ashtray to make it fit! :( Edited December 23, 2008 by Anees (see edit history) Quote Link to comment Share on other sites More sharing options...
