jacko Posted August 2, 2008 Share Posted August 2, 2008 Rite, im confused, since ive had my TT its always hit 1 bar on the boost gauge, it has a blitz cat back & panel filter and both cats are still there. I put a Blitz Access ECU on today and the boost has dropped to 0.8 bar, why would this be? Also i think the stock recirc valve is knackered and leaking boost, maybe it has finally given up the ghost and it just happened to coincide with putting the other ecu on. Any other ideas?

Homer Posted August 2, 2008 Share Posted August 2, 2008 The stock valves rarely fail, it's got to be due to any change you made. If it was working before, and not now then it's more confirmation it's not the issue. Why did you install the new ECU - what changes does it make?

mikeyb10supra Posted August 3, 2008 Share Posted August 3, 2008 (edited) The stock valves rarely fail I thought the stock recircs were very prone to failure? They are more hassle then they are worth imo....I would just cap the thing off and be done with it Edited August 3, 2008 by mikeyb10supra (see edit history) Quote Link to comment Share on other sites More sharing options...
colsoop Posted August 3, 2008 Share Posted August 3, 2008 well a quick check would be to put the stock ECu back in and see if it goes up to 1 bar again. Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted August 3, 2008 Share Posted August 3, 2008 well a quick check would be to put the stock ECu back in and see if it goes up to 1 bar again. yep...that makes sense, it stands to reason that the new ECU is the problem if it worked fine before Quote Link to comment Share on other sites More sharing options...
jacko Posted August 3, 2008 Author Share Posted August 3, 2008 ye i'm gnna do that 2day and see wat happens. I think the recirc valve mite be on its way out, as i vented it to atmosphere the other day and it appeared to be opening before i let off. So i'll have a look at that too and let you know what happens Quote Link to comment Share on other sites More sharing options...
SimonT Posted August 4, 2008 Share Posted August 4, 2008 Can I just ask what should it boost as standard as i seem to have read quite a few different threads that all say different figures?? Quote Link to comment Share on other sites More sharing options...
