NEWSFLASH!

[dutchie]

I received a phone call from Ford today regarding my questionnaire after purchasing my new car back in end of June and I mentioned that I get the occassional overboost and it seems the Wastegate remains closed for about 2 seconds until I take foor of the pedal and then lightly reapply.

I mentioned I only get this when it is really cold in the morning or late at night.

Although this has only occured about 5-6 times in the past 4 months, its no real big deal at this stage.

The service rep mentioned that I should contact my dealer service department in about 6 weeks time as the fix has been identified. He confirmed that Ford recognise this fault and their testing confirmed what I said above.

He mentioned that the fix will rectify it as well as give me better performance.

Although he did not mention what the details of the fix were, he said I will be extremely happy with the fix. (under warranty)......

So this is good news I think.......

Is this fix # 84 ...

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

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 had bad over boost, it was spiking to 11psi and this happened from when my car was new. Ford service had 2 goes at trying to fix it, but it was no better.

I took my car to APS in Melbourne and they had problems with knock and boost spikes and spent many hours tracing the problem. It turned out the knock sensor was not plugged in

I do not know if this was the casue of the overboost (I doubt it) but since my unichip, I have not had any spiking and the car feels better.

I will be removing the unichip soon to see if the problem comes back.

I think its the boost controler that comes with the Unichip that fixes the issue, or smooths it out. SInce the factory one is pretty lame at controling the boost.

Mal,

I've found that it’s not easy to replicate the problem for test purposes.

I drove to Melbourne a week ago, I hit boost cut just once, during just 1 out of a number of aggressive overtaking moves, and driving into a cold southerly.

When I last drove down from Queensland to Sydney on a cold night I got boost quite a few times, and far more prevalent with revised gearing that I had, with much quicker acceleration in really cold air.

I went to WSID, did quite a few runs, not 1 overboost, and I expected it... but it was a warm (22 degrees) day.

I had overboost situations when my car was stock, but only a coupe of times.

The guys with Unichips that have privately reported boost cut have found it on very cold days and cold nights.

I'd expect that if APS resolved the issue they'd report it to us. I've reported the issue to Chiptorque. I'm not sure if the TSI has the same issue, as it drives the injectors directly. Certainly when I move to Motec I never expect to see it again. I've never had the issue with any of my other turbo cars, so the sooner Ford changes their software the better off we'll be.

In general terms my conclusion is that the higher the boost, the more aggressive the tune, the colder the air, the lower the gearing, (with the right foot on the floor) the more likely the problem.

Compared to most I run higher boost, more aggressive tune and lower gearing, so I’m lucky I don’t live in Melbourne.

Anyway, this is my observation.
