Have you had the boost sensor output slugged as I described, whcih can easilt be done by your tuner using the Unichip software. 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.

Hey Dingah, no I have not, but it will be the first thing I follow up on with Dynomotive. I still have to go back there anyway so I will take the appropriate information. :kissmy:

Thanks.

Hi Brian,

I was in Warwick just after you had been there must have just missed you, I didnt have any problems with my car apart from having to put some standard unleaded it which caused it to feel rough through the mid range which was fixed with a bottle of Octane booster, the temp at the time I think was in the low 30s.

Im not saying that my car is cured but since mods were done its been fine. I am still useing the 3.46 diff but there has been times were the car has lost traction and spun up pretty quick and still no boost spike, maybe ive just been lucky so far either way im just reporting what my car had done.

Frank

Pm no on its way

will the bossedit be able to fix this???

Perhaps, but so far this option is all talk ... I am keen to see it working and I suspect when editing the ECU the tuner can change any factory option (or failsafe). Ford is known to have detuned the Xr6T for long term reliability so I am sure their is alot of room for improvement !!!

Brian, keen to see how the Motec goes ... I am sure this will fix any issues you are having ... not many v8Supercars with issues :kissmy:

Cheers, Jason.

Well after 11 (yes eleven) cut outs between Sydeny and Coffs Harbour I rocked into a Ford dealer and got 'codes' off the ECU.

4 codes pulled off all centering on Wastegate and O2 sensors....

Will be onto the Canberra guys now to see if they can fix ;)

Aaron don't bother with John McGrath, they had absolutely no idea beyond whatever the codes were telling them which is like knowing the outcome with little idea of the cause. Took DTS/APS a few hours of careful and logical fault finding to tie my issue down.

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.

Brian you are abslutely spot on, this is exactly what happened to me on the Bells line of Road, returning from the Bathurst cruise, scared the :spoton: out of me.

And I was not the only one suffering from this on that freezing day on the mountain , all had chips to :ermm:Have only had it happen once since

Is this fix # 84 ...

Sorry to be cynical but I've gone Unichip to solve it :spoton:

Cheers, Jason.

Jason,

To my knowledge Unichip does NOT solve overboost, based on feedback from other forum members using Unichip, nor does the XEDE.

The boost cut is as usual more prevalent in certain cars, and from what I can ascertain more likely in colder weather.

Who told you that the Unichip solves this issue?

Brian

I believe you're correct bcl.I had an xede installed believing it would fix the problem and if anything in cold weather the overboost got worse.Every time it got a bootfull first up on a drive(not stone cold, but say 10 mins steady driving) it would accelerate hard up to 3500-4000 in 3rd gear and then breakdown/lose power and go into limp home mode sounding like a 3 cyl Daihatsu Charade.Since regapping the plugs and warmer weather it hasn't been so bad.I've adopted your method of progressive and steady acceleration when passing just in case but I sure hope Ford have come up with a fix.

My car's been running like a heap of sh!t since the 15k service (yeah, I know I've said this in a few threads... sorry). The dealer says that I now have to wait until FoMoCo release the new flash upgrade. Why? I asked. The car was running fine before the 15k service so sure it was something that was done during the 15k service. The dealer said that apparently it was faulty software uploaded to the car's ECU during the serivce and now all their customers have the same problem - overboosting. So in the meantime, they've bypassed the wastegate solenoid and I'm waiting and waiting for the fix. Grrrr.

Good to get so many replies.............sounds like I'm one of the lucky ones and I live in Melbourne.........with just the odd overboost.............

Lets hope Ford do finally have the answer.

As I mentioned this came directly to my New Car Questionnaire and my only fault on the car.....the odd overboost (wastegate error).........

I'll keep you informed but remember to all contact your Ford dealers around mid December......

cheers
