p3te Posted November 16, 2012 Share Posted November 16, 2012 ive had my bpu tt set up and mapped to run turbos and parallel for a few year now but just been out and its running in sequential again? how could it start running like this again when i haven't re connected the hoses to run in sequential, ill check it out in the day to see if there's anything like hoses popped off but not sure how it could go back like that without re connecting the vac hoses up Quote Link to comment Share on other sites More sharing options...

p3te Posted November 17, 2012 Author Share Posted November 17, 2012 (edited) Was done when I had car mapped from what I seen some hoses were disconnected in the bay then emanage blue fitted to make the most of it, I'm going to have a look today and follow the article on mkiv.com Edited November 17, 2012 by p3te (see edit history) Quote Link to comment Share on other sites More sharing options...
p3te Posted November 17, 2012 Author Share Posted November 17, 2012 Just checked that article it looks a bit of a faf on wiring the actuators open and it says not to run like this for more than a few days, is this the way most people do it? Strange how its just went back all of a sudden with the hoses still disconnected, Quote Link to comment Share on other sites More sharing options...
p3te Posted November 17, 2012 Author Share Posted November 17, 2012 Here's how I've got the hoses connected top vsv Bottom vsv the hose I'm holding goes straight to the exhaust actuator the thicker hose goes up and connects to the vac hard pipe Quote Link to comment Share on other sites More sharing options...
p3te Posted November 17, 2012 Author Share Posted November 17, 2012 What are these 2 hoses ? One is capped and the other just hanging Quote Link to comment Share on other sites More sharing options...
p3te Posted November 17, 2012 Author Share Posted November 17, 2012 Bit baffled with this now I've checked a few sites and the vac lines are connected right but still it runs the same, when ryan mapped it he put it to ttc as one of the vsv were faulty and the 2nd turbo wasn't spooling, its been running fine with both turbos working best part of 2 year now its went back to sequential, the sound has went back to how it was and the turbos spooling early again as if it was back to running sequential, I don't know how tho with the vac lines connected the way they are Quote Link to comment Share on other sites More sharing options...

p3te Posted November 18, 2012 Author Share Posted November 18, 2012 Running ttc should the exhaust valve be open all the time? Looking at this now its not moving at all not even when I rev it, it was rattling quite loud a few weeks ago if this has failed that would explain why turbo 2 isn't working and I'm not getting the ttc sound is that right? Also I read these can be bought but part of it is fixed to the turbo and if it needs changing the turbo does as well? Quote Link to comment Share on other sites More sharing options...

hodge Posted November 18, 2012 Share Posted November 18, 2012 Everytime I've done a TTC I've used 1 way valves. There isn't any in there at all. That long thin pipe in the last pic that's just hanging should go to the exhaust bypass valve with a 1 way valve in it so when it opens the 1 way valve holds pressure and keeps it open.

p3te Posted November 25, 2012 Author Share Posted November 25, 2012 Can anyone confirm, should the exhaust valve be moving when I rev it? Quote Link to comment Share on other sites More sharing options...
hodge Posted November 25, 2012 Share Posted November 25, 2012 It won't when you run it in sequential mode but I'm not sure how Ryan has don't the parallel mode, if he's plummed it under manifold vacuum then it probably Wil. Quote Link to comment Share on other sites More sharing options...
p3te Posted November 25, 2012 Author Share Posted November 25, 2012 this is how its connected up first one correct? 2nd one the hose im holding goes straight to exhaust actuator and the thicker hose goes down and is connected to the left of the red cap and these 2 are capped off Quote Link to comment Share on other sites More sharing options...
p3te Posted November 27, 2012 Author Share Posted November 27, 2012 Is that right? Quote Link to comment Share on other sites More sharing options...
hodge Posted November 27, 2012 Share Posted November 27, 2012 Well it's not how I would have done it but I suppose it would work. To be honest, I'd need to see it to see exactly what's where. Quote Link to comment Share on other sites More sharing options...
p3te Posted November 27, 2012 Author Share Posted November 27, 2012 ive bought some of them 1 way valves gonna fit them the weekend, i have a feeling its a problem with the exhaust actuator, which way would you have connected it up? Quote Link to comment Share on other sites More sharing options...
hodge Posted November 27, 2012 Share Posted November 27, 2012 I'd have left it plummed as it should be in sequential but put a 1 way valve between the exhaust gas bypass valve and the VSV and a 1 way valve between the top turbo actuator and VSV. It should work as it is but I've a feeling you've plummed in the exhaust bypass wrong when you changed your pipework. Quote Link to comment Share on other sites More sharing options...
p3te Posted November 27, 2012 Author Share Posted November 27, 2012 is there just the 1 vac line going to the exhaust bypass? Quote Link to comment Share on other sites More sharing options...

p3te Posted November 27, 2012 Author Share Posted November 27, 2012 im not sure how if its just the 1 hose, thats the one in the 2nd pic where im holding the hose? that goes straight to the actuator Quote Link to comment Share on other sites More sharing options...
p3te Posted November 27, 2012 Author Share Posted November 27, 2012 is there any way to check the actuator? Quote Link to comment Share on other sites More sharing options...
hodge Posted November 27, 2012 Share Posted November 27, 2012 I'd need to physically look at the pipe configuration to see how exactly it's plummed to see if it will work right. Quote Link to comment Share on other sites More sharing options...
