Any one got any news, im realy fed up with it !!

Have noticed thogh with the weather being warmer the last couple of days its not nearly as bad !! Interesting!!

Im considering getting a link ECU as i wanted one any way! Im hoping this will sort it!

Any one else had experiance with using an ECU Upgrade as a fix??

Thanks

Denz

P.S>

How do i contact IM any one got there number, im gonna give them a peice of my mind :-(

Guys, I suspect that Subaru will not be in a hurry to fix this problem. I'm sure most of their resources will be tied up in launching/evolving the MY01.

I think the question to ask is if the MY01 WRX also suffers from the same problem. They can hardly say yes!. It's taking scooby fans enough time to get over the alian looks of the car.

If the problem is fixed in the MY01 is fixed. Can this fixed be deployed in pre MY01 cars.

Denz

Thanks for the numbers you two!!

Any way spoke to IM and they said

Its never gonna be rectified! Over the years the boost has been dropped, along with the fueling, all for the emmisions. Theres nothing they can do! They can only do so much to a performance engine!

I can simpavise with them as they dont have problems else where!!

Its all down to rediculas emmision laws

Any way looks like i may get a Possum Link ECU. BR Developments assures me that this will fix my problem! and make it go like a rocket

thanks

I must say that I agree absolutely with Lambo's recent post - I can't see any way that this problem is caused by a defective ECU. The general trend seems to be that if you suffer from the problem, then it tends to appear after you've built up a reasonable mileage. If it was ECU-related, then IMO you would experience it from day one. Period!

I don't dispute for one moment that you guys aren't experiencing significant probems, and that it isn't a real pain in the proverbial. I just can't help feeling that the solution lies in a different direction.

Fortunately (so far!) mine is fine - MY00, with 5500 miles. I get a little surging first thing when the engine's cold, but I don't care about that as I'm just concentrating on keeping it off-boost. Doesn't last very long anyway.

Sorry this is not more helpful, but I think you're wasting your time with the ECU route.

what about a call to WATCH DOG they love to shovel sh*t on so called good service companies.

mines had it slightly since 3k.

PeteC

I'm sorry, but I just don't understand this. For any particular model year, and assuming that we are talking about a UK/EU car, there is presumably only going to be one software version which gets programmed into the ECU.

How do you then explain that some MY00 cars, for example, don't experience the problem? I thought that all this EU emissions stuff related to the "half boost" problem mentioned by Pete Croney some while back. As an explanation, this just doesn't ring true to me. Are you sure that you weren't talking to the DVLA - they tend to talk b*llocks too!

Apologies in advance if I'm wrong.

It's not really us that have been chasing the ECU route - it's Subaru telling us that's where the problems lies. As far as I know they haven't changed their minds ?

It is a big issue if Subaru UK cannot fix the problem. Under UK law goods have to be fit for the purpose for which they were sold. They also have to conform to their description. The faulty vehicles are neither and whoever shoulders the burden of this particular problem it should not and will not be the customers. It is Subaru's problem period. They cannot sell vehicles trading on reputation and then turn round and say "Oh well, sorry, tough luck those who got the faulty ones". Watch this space.

vmax - every road test I have read on the MY01 WRX has mentioned that the engine has "hiccupped" at some point. I'd lay money on it being the same problem. Perhaps even worse as Emmissions regs for 01 cars I presume will be even tighter.

I would like to know if any one has had this
sorted out yet

bob

Hi
Had mine sorted. Only cost me a few grand but no hesitation now. Smooth right through the rev range. As you live nearby you could even try it.

TopCat

Guys,

I had a surging problem when trying to cruising at 95-100mph at part trottle, they select monitor when I checked the ECU showed everything to be fine apart fron the graph which shows the air being dumped. So I took the Forge piston DV apart and cleaned it hit it with some WD40 and thank god problem sloved......Try it guys (people with DV) if you already have and it does not sort the problem than I don't have the foggyist.

Ok guys, what fuel do you run your car on??
How do you start your car and do you let it idle for 20-30 secs before pulling off??
Do you run your car down at the end of a journey??
Do you only do short journeys in your car??

I always run my car up, give it 20 - 30 secs, i always (well 99%) give it 4-5 miles before opening up the throttle a bit and i try to keep out of the turbo when im in town, i always put SUL in my MY00, except the fuel crisis where she had UL and some octane booster
I run my car down after a long or short drive (turbo timer ) My car suffers from none of the above problems, no surging, no clutch judder, ive done 8.5k miles, no modifications, my car is a standard Turbo.
It may be the way you drive the car or the fuel that you put in, the other people i know dont have this problem and warm their cars up before giving them some welly.

RB5SCOTT

Mines doing it now!

full SS system, ITG, SUL,Octane(not PPP),16000miles

really bad at 3000rpm especially in 5th(80mph)

Neil Barnes

Is there any one interested in taking this matter up. I am about to start a court case with my local dealer and subaru. I am looking for details of your experiences of this with your dealers and subaru uk. Please could any of you email me neilbarnes@futuretv.fsnet.co.uk
I am not looking for money i am trying to make subaru do something about this.

Meshwolf

Mine's doing it too! It's been doing it since it was new, but it has never been very annoying. Now I have a full custommade exhaust w/ downpipe and PiperX inductionkit mounted, and it feels a little bit more apparent now. Could it be the totally worthless airflow meter that's causing it?

Anyways, it's not just happening to UK cars, it's the same here in Sweden. I guess we have the same specs though, but it feels like this is a case for Europe, not just UK or Sweden or ...

regards,
Pär

ARRON BIRD

My P1 started doin it when cold about 6000 miles and then no problems. Now 10000 miles and does it all the time...when little or no throttle is deployed.
Just give it extra stick.
I wouldnt say it was a major pain in the **** but can be a bit hesitant sometimes.
Standard car always on sul. Will be fitting bpm twin dp and centre soon so hope it wont make it worse

Mungo

Just to add another voice - I too have the same problem. MY99 std UK turbo. Worse in v.cold weather, and worse when using SUL. Most noticeable in 5th at about 80mph.

IanWatson

One more voice of dissent - just bought a 22k miles, LHD MY99 in the Netherlands - did all my research on warming up/cooling down - it gets a good 15 mins before venturing beyond 3000 rpm, and only gets SUL to drink.
It has the surging when cold (ie significant proportion of my daily drive)- but, thank god, not noticeably when it has warmed up.
Aaagggggghhhh!!!

Berkeley

I had this problem on my RB5, sometimes quite violent jerking/hesitation. This problem has now gone since having an induction kit fitted, the original filter was very dirty. It seems that most people have this problem after running up several thousand miles; maybe breathing is where the problem lays.

spudgun

got surging/pulsing around 3000rpm mark when not fully warmed up. since having ppp, absolutely no surging whatsoever. this car now feels like she doesnt need warming up full stop! i have to stop myself going over 3k rpm for first 10 minutes! ppp is a highly recommended, if not expensive cure.

nickw

Just had mine inspected by regional service manager with follow up letter from Subaru.

Apparently the core problem "pulsing" between 2500 - 3000 rpm is a feature or characteristic of a turbo charged engine. It is related to the Turbo being incapable of producing a reasonably linear increase in manifold pressure. It is a normal characteristic of the 99/00 Turbo.

I watch Subaru's reaction to this problem with increasing incredulity. Each explanation seems to generate more questions than answers, such as

Turbo output doesn't usually pulse for no reason - is it turbine speed varying or bad turbo vane/output/inlet manifold design ?

If it is a normal characteristic of a turbo charged engine, why do none of the other turbo charged vehicles (including new ones this year) I have driven do it ?

Why does resetting the ECU temporarily make the pulsing less noticable ?

Why does a replacement ECU not from Subaru, be it Prodrive, Link or whatever, appear to solve the problem ?

A story on this issue was published in Auto Express a few weeks ago. The problem was acknowledged and it was stated that it was up to the owner whether they could live with it or not. This implies a choice, anyone had any proposals ?

nick

Neil Barnes

Nick the new ECU from prodrive ie PPP still has the same problem it just makes it more noticeable. It looks like I am changing mine for a P1. With a letter from IM stating that the P1 does not have this problem

Neil

Andy-D

Has anybody with this dreaded surging, hesitation problem tried curing it with either a MOTEC or UNICHIP ECU?

If so does it work and do you recommend it?

Andy Burrell

Yet another voice of doom and despondancy. My 99MY does it, and the colder and damper it is the worse it gets, tick over is about 2000 when it starts and then fluctuates between about 1200 and 200 rpm. I run SUL and occasionally some Millers, car has done 19,000 miles. To just top it all of the clutch pedal keeps clicking and the biting point moves. Well p155ed off.

Julian

Andy,

I think you've already reached this conclusion - it doesn't sound like the same symptoms to me. Does sound simmilar to problems I've seen reported here before and were easily sorted so I'd take it along to your dealer.

THORPEM

I have a MY98 that has started juddering like it is missing in 4th and fifth between 2000-3000 hardly noticable when cold but worse when it gets warm or after a long run. Dealer has moved knock sensor, fitted 2 new leads and changed boost solenoid in the last 5-6 weeks but problem still persists. They keep refering to the memo from subaru about hesitation in MY99 & MY00 and saying it is a characteristic. Can anyone help? Any comments, is it the same problem ?? I don't seem to be getting anywere.

tonybooth

If you see some of my earlier postings in this thread you will see that I have suffered from 'The Surge'. After some serious workings, lots of letters and phone calls my car is 95% sorted and I have accepted this as being as good as it can be without comprimising performance (Currently 237 bhp) The faults were not deemed to be related to the 'Characteristic Surge'. Thanks to all involved.

TONY

druddle

must say, my my01 wrx shows the same power surge/blocking talked about here. one dealer said it was turbo lag when i explained over the phone, but iots going in to another tomorrow.

it all happens at 5500rpm and over when the car has been running for at least 20 mins (motorway-type driving). hmmmmmmmmm.

see the "UK 2001 spec WRX down on power" thread for more info.......
