My tuning folk and Peter's folk went over this some time ago and it has completely addressed the issue with no recurrence. For those without Unichip not so sure but assuming the cause of the issue is the same I wouldn;t mine betting that Ford's temporary fix was to disconnect that boost sensor which might be ok for a limited time under careful driving but couldn't be recommended as it removes an important safeguard from the system. THus if you can find a way to reduce to reduce the output but still have it relational to boost pressure ........?Dingah Link to comment https://www.fordxr6turbo.com/forum/topic/13481-newsflash/page/2/#findComment-178082 Share on other sites More sharing options...

As a Canberra resident the combination of altitude and temperature made it a bugger of a thing here which kept occurring alost every day yet oddly seemed to disappear at the coast till we anlaysed the cause and effect. Even with Phase II it is now totally solid and reliable.Dingah Link to comment https://www.fordxr6turbo.com/forum/topic/13481-newsflash/page/2/#findComment-178124 Share on other sites More sharing options...

We have mentioned the voltage clamp adjustment in a thread elsewhere, and that both the XEDE and Unichip address the issue.The point I make is that this so called "solution" mitigates the problem, it does not eliminate it. It does not solve the problem via a proper design change. If you think I'm wrong let me know. I have seen a number of times the boost cut in dyno runs, and the voltage clamp change to stop it. However, under certain conditions the problem still occurs on the road. The problem would be most easily solved via Ford changing their base program to stop it, or not using a piggyback.Brian Link to comment https://www.fordxr6turbo.com/forum/topic/13481-newsflash/page/2/#findComment-178263 Share on other sites More sharing options...

Ive driven to brisbane and to Melb twice so far all is good.The boost was a bit erratic when it was standard since the upgrades its a smooth curve and has never gone over 14 & 15psi usually sits between the two right to redline.Frank Link to comment https://www.fordxr6turbo.com/forum/topic/13481-newsflash/page/2/#findComment-178264 Share on other sites More sharing options...
bcl Toughest BA Turbo Lifetime Members 3,408 Member For: 22y 4m 11d Gender: Male Location: Sydney Posted 20/10/04 10:45 PM Share Posted 20/10/04 10:45 PM That's good Frank.I drove to the Sunshine coast in the school holidays and not 1 boost cut. I drive 70km to the city each day, and in weekday driving I haven't had the problem once this year.Does that mean that the problem does not exist? No.For me it does occur only in 'foot-to-the-floor" very aggressive acceleration, and as I said is not always reproducible. The dangerous aspect of this is that it may occur when I'm overtaking someone on the open road and there's a car coming towards me. I have now modified my driving style, to not overtake quite so aggressively.Frank, I assume that you're still running the 3.46 diff. You may find that using say a 3.73 that you may get the problem. When I went from a 3.73 to 4.10 diff I found it was much easier to get boost cut in very cold conditions.Brian Link to comment https://www.fordxr6turbo.com/forum/topic/13481-newsflash/page/2/#findComment-178270 Share on other sites More sharing options...

For me its not a big deal (haven't had one for a couple of months, and alot less since they regapped my plugs) its seems as though my car has settled down after a few K's... But I agree we are working around a fault in the ECU ... so if Ford has rewritten the code to fix ... I am the first in line at the dealer Still sceptical though because this "Fix" has been mentioned many times ... and now the Mark II is iminent and they haven't solved it yet ... really shouldn't have been their in the first place ... may just be Ford AUS inexperience with Turbo cars as I am sure none of your Subi's have a drama Cheers, Jason Link to comment https://www.fordxr6turbo.com/forum/topic/13481-newsflash/page/2/#findComment-178274 Share on other sites More sharing options...
