Hi,

My 02 WRX has an annoying habit of blipping the engine revs when up changing above 3500rpm, after a period of quick acceleration. The blip is about 500rpm and means that the revs take a good couple of seconds to drop down low enough to match the next gear.

Is this a normal thing to help keep the turbo spooled up or possibly a problem with some form of Bipass Air Control.

The car otherwise seems to drives perfectly well. Not owned a Subaru for long do maybe it's just something to get used to.

Thanks in advance
Gav.

 

Welcome to Scobynet

The rise in revs on gear change has been mentioned by a lot of MY01 / 02 owners and seems to be the norm ........."they all do that" as Subaru would say !!

Mine used to do it until I had the car remapped but it never bothered me as I just changed gear anyway and let the syncro take care of it all

Midlife.....

 

my 02wrx mine does it aswell i ignore it and accept it,

 

My 01 WRX does it also and it's had a remap. Only really noticeable when driving slow-ish and changing at say 4K revs. When I'm gunning it, not a problem

 

yup same as!! Mine blips up too... MY51 Buge eye!

 

I have had the PPP fitted on my WRX (bugeye late 01) and I notice this effect more now than before.

I think someone from Prodrive explained that it is down to the lag between you lifting on the throttle and the boost being reduced

some days are worse than others and it is really quite annoying as it makes you feel you do not know how to drive properly

 

same as above. Ignore&accept. What I do is that I change gears outside that range, so this doesn't happen then any more In town I change at 3000 rpm, outside or at hard acceleration I change at around 5000, or sometimes more.

 

Thanks for your feedback.
