liamg40 Posted July 5, 2013 Author Share Posted July 5, 2013 It's not a problem with the actuator I had it running on a car over here and it ran fine beforehandSo how come everything went back to normal when I changed back to the standard setup?Am I missing something here? Could anything else cause this to happen Quote Link to post Share on other sites
liamg40 Posted July 30, 2013 Author Share Posted July 30, 2013 I fitted a new adjustable actuator today and exactly the same thing happened again,So the problem is on my car but no idea what it is,The car boosts perfect with a standard actuator fitted but as soon as I fit an adjustable one it will not hold boost at all, if I accelerate the boost would fly off the boost gauge if I let it,I've got no idea what it could be but I'm gonna get good access to the turbo tomorrow and have a good look to see if I can find anything obvious.

Ryan_EP82 GT Posted July 30, 2013 Share Posted July 30, 2013 That's real strange there mate :S "The car boosts perfect with a standard actuator fitted but as soon as I fit an adjustable one it will not hold boost at all, if I accelerate the boost would fly off the boost gauge if I let it"Sounds as if the there is no actuator plugged in at all allowing it to boost freely! If you've one single loop going from turbo to actuator I'm baffled man Quote Link to post Share on other sites
JayJ Posted July 31, 2013 Share Posted July 31, 2013 Put some pictures up how you have installed the actuator and vac lines Quote Link to post Share on other sites

Browner Posted July 31, 2013 Share Posted July 31, 2013 So my part wasn't faulty like you said Quote Link to post Share on other sites
bucketep91 Posted July 31, 2013 Share Posted July 31, 2013 are u adjusting the actuator properly? Might sound daft but a local lad was having similar issues, said he had tried adjusting it both ways. He was just twisting the whole arm and not the threaded part. I loosened the nut gave it a couple of turns and it was perfect Quote Link to post Share on other sites
liamg40 Posted July 31, 2013 Author Share Posted July 31, 2013 So my part wasn't faulty like you said But I also said if I was wrong I will hold my hands up straight away and I did just that by sending you a pm saying sorry. Quote Link to post Share on other sites

Yeah mate I'm adjusting it properly, I'm starting to suspect the steel ruler I'm using now commits only a cheap one, I'm just about to get the vernier out and double check these measurements.

liamg40 Posted July 31, 2013 Author Share Posted July 31, 2013 Just measured the ruler and the actuator using a vernier and it was 2mm out.123mm was 125mm on the vernier so even though it it out it still shouldn't play up like it is,Couldn't get a look at my engine bay today because it's been pissing down all day but I'm thinking about just going straight ahead with my forged td04 build now instead of trying to get to the bottom of this as I've got all the parts together now just need a decent clutch.Thanks for all advice.

Ryan_EP82 GT Posted July 31, 2013 Share Posted July 31, 2013 (edited) Mate I would say wind it in til about 100mm and see if it can hold a steady boost just under fuel cut. I had mine wound right the way in and the oem boost gauge went to the max, which was roughly 0.8bar/12psi.If it does overboost (to 0.85bar/12.5psi) you'll hit fuel cut, so you'll know to turn it down a few threads from there anyway. I'm sure it'll he sortd handy enough pal I doubt both of the actuators are faulty. Edited July 31, 2013 by Ryan_EP82 GT Quote Link to post Share on other sites

Ryan_EP82 GT Posted July 31, 2013 Share Posted July 31, 2013 To be honest you would think it bud, but it took me about 20 or so full turns to move up 4 psi on a brand new actuator.On the stock ecu I know as long as boost is below the .85bar it fuels ok, not sure bout the jam tho!

liamg40 Posted August 1, 2013 Author Share Posted August 1, 2013 I've had an idea, I've had my black glanza back off my mate so I'll try the actuator on that one and if the same thing happens I'll know that it's down to the adjustment then,As soon as my missus finishes work in it I'll give it a whirl.

mikey4410 Posted August 1, 2013 Share Posted August 1, 2013 Hope u get it sorted soon..so surprised its giving u jip still.hows the brakes ? Quote Link to post Share on other sites
liamg40 Posted August 1, 2013 Author Share Posted August 1, 2013 Hope u get it sorted soon..so surprised its giving u jip still.hows the brakes ?I know, I reckon it's the adjustment now, it seems like people are adjusting them differently on different cars to achieve the same boost levels, I think I've got to find my settings for this car turn by turn I suppose.

Ryan_EP82 GT Posted August 1, 2013 Share Posted August 1, 2013 Happy days mate glad you're getting somewhere I couldn't even get above 5 psi when I got a new turbo fitted with an old actuator, I replaced it with a new adjustable one and it sorted it out, trial and error.
