  1. Thanks for the replies, I think it's the characteristics of the new cams moving the power band further up the rev range, I've checked for leaks, plumbing and wiring and can't find anything wrong. Think I'm limited to the gtx in a standard location housing and 1.8 bar is all she'll flow. Looking into getting a new turbo now
  2. Sorry, it was a 2.0l with uk 2000 heads, now it's a 2.1 stroker with sti heads. It's a road tune, timing down low was pretty similar but has to pull alot of timing up top. OK, I'll check for exhaust gas leaks pre turbo, I'll go over everything, intercooler piping etc I can't see why the actuator spring would have failed,
  3. Hi guys I got a gtx3071r with the standard subaru housing to fit on my sti, 20% duty cycle saw 1.8 bar and full boost before 4k. I've built a 2.1 stroker engine and everything else is the same. But now 20% duty cycle doesn't do anything and I kept adding to see if it would start boosting and got to 1.8 bar at 80% duty cycle and it wouldn't go above. But doesn't come in until 5k. I genuinely expected earlier spool and if anything having to run less duty cycle. Has anyone else had this? If so what was it and any suggestions would be great.
  4. I took it out and cleaned it, turned on the ignition and it moved out and back when i turned it off. but still wouldnt work. I grabbed a second hand part from my local subaru specialist. when i took the old one out it sat about 5mm further back than the new (second hand one). i checked the part numbers where the same which they where. i plugged it in and it travelled alot further out, turned it off and it went all the way back and returned to the same position it was before. i fitted it and set up the base idle position table again and touch wood shes started 6 times now and achieves the rpm ranges set. it was frustrating because the part seemed to move and work as it should but.... i no longer have to set the base table with different numbers everytime i start ;-) happy days
  5. Thanks for your response, I shall take it off and clean it up again and maybe take the throttle body off and clean that out again. and then try again and get back to you.
  6. Hi guys (newbee here) I have a issue and wondered if its a simple case of a new icv or if I'm missing something and was hoping someone could help?? when setting up the idle, I make sure all other supports are turned off, I put it in open loop idle control and open idle control base position table. I start the car and adjust the numbers until it idles exactly where I want it throughout the temperature ranges. get it up to running temperature and its perfect. I rev it, drive it and it comes back to a perfect idle at -75kpa. I then turn it off and back on and the car revs at 2k at -65. I go back into the idle base position table and turn the numbers up until she idles at 900 rpm again and its perfect. park it up and when it gets hot its doesn't wanna idle at all. I turn the numbers back down and she's fine. going round in circles, am I missing something? sorry I haven't got my laptop with me right now or I would upload log files. the problem is. the car idles fine at either setting once set up so I don't think its the idle control valve. but why am I seeing different manifold pressures at different times? things I was going to check next is a vacuum leak, re check all my vacuum lines, check the throttle is shutting properly, but I just wondered if anyone else has had a issue like this and what they did to fix it? I'm using a link v5/6 plug in ecu. thanks in advance guys
