They come with different boost maps but from what I've heard most people seem to have around 270-280 bhp. E-mail Scott T or David Wallis for more details

Sorry Pavlo I blame it on the late nights and vast quantities of alchohol that I don't seem to get anymore

You can get it from Pavlo too

hi all i own a 93 wrx which has an intermitent fault (keeps holding back like its a none turbo) have posted it on here before and have tried every thing that every body has sugested still no joy. does any body know where i can take the car to have it looked at as the places i have been to so far tell me they have cured the problem then when i collected the car on the way home it is always the same. i live in kent but dont mind traveling if it means getting it fixed. cheers

 

Mine had the same problem. Fixed it by changing the knock sensor.

 

already changed that along with so many other bits could realy do with taking it some where now where they know what there doing and wonttell me its fixed when its not

 

M8 it seems there is alot of us that is suffering this problem at the moment, I can not believe that NO ONE has an answer, it seems to be a hard fault with the cars.

Cause everyone tries one thing or the other and it goes away but comes back!!!
So there is deffo a common same problem with this....

Good luck anyway!

 

You probably have tried this (93wrx)... i had similar problems which were result of incorrect plug gapping

Should be 0.7mm

Have you tried cleaning the boost solenoid


Coil packs get alot of mentioning also.

frank

 

Try Scoobysport or Xtreme Scoobies in essex - it's not that far....

 

plug gaps ok i have cleaned and changed and by passed the boost solonoid. unfortunatly scooby sport are one of the places the car has been and they fitted a new lamba sensor but it was still the same in the end they didnt have clue

Do you have a boost gauge/knocklink/afr fitted? My 93 wrx was only putting out 0.5bar boost which ended up being a leaking pipe from the turbo to the intercooler. It is made of hard plastic with a "flexible" section in it and it was here that it had split. After changing it out for a samco hose set from Rally design then my boost went up to 0.7 bar. I also fitted a scoobyecu which has made a lot of difference to the way the car drives, much smoother, faster spool up and more power. Speak to David Wallis or Scott T for details of the ecu.

Do you use octane booster and Optimax/SUL as this made a big difference to mine as well

 

If Scoobysport can't help you, Xtreme (Knowlesy) will -

meant to say hi what colour etc is your scoob, I'll keep a eye open, it would be nice to get a friendly wave, it doesn't seem to happen often around Tonbridge.........

MY99 DBM Janspeed (Sccobysport) zorst, Ecutek, Prodrive 17s

 

dont have a knock link or afr fitted but yes have a boost gauge dont use an octain booster but use shell optimax. the bad thing is the problem is intermitent .one minute is boosting ok then the nxt not so good . there is no set pattern either .tonight on the way home boost was down to .3 bar then ten mins later back to .8 but still holding back. the car is black/ black windows,evo rear spoiler and 17 bk gold alloys .ps fitted cam sensor last night and reset ecu .ok for about 10 miles then back to naf again

please some one must have the answer to this nightmare. i have been trying to sort this problem out for nearly a year now and have nearly had enough . any help would be appreciated cheers

Have you tried resetting the ECU? Do you have any fault codes? Mine did the same, hesitated in top gears, turned out to be a knock sensor. You say you have replaced this, was it new or second hand? If it was second hand did you measure the resitance of the sensor, I can't recall what it should be but there is a website that tells you how to do it. If you want me to i will post it on here once I have found it.

 

knock sensor was second hand so not sure if was ok or not. the car has no fault codes

 

yea Post it on here please if you find it.

Btt

 

Manual can be found here it's about 40 odd meg though just for the pre 97 manuals!

 

0.3bar is limp mode isn't it.

I had it lastweek after i fooked up cleaning the maf sensor, new sensor got full boost back.

if its not a sensor fault, it may be a connection problem.

try removing your connector from each sensor in turn, give it a clean with some emery cloth to remove an oxidisation and give a squirt of wd40.

other possible is a semi broken wire, tracing that would be a pain, maybe a trip to an auto sparky might help?

cheers

as any body got a picture showing where the map sensor is

 

Picture on this thread

 

I had a very similar problem on my early model car - intermittent poor performance - improved after doing a reset of the ecu then degraded again every time.

It turned out that a wire leading to the Lamda sensor had rubbed against a hot pipe and had melted exposing bare wire. This in turn would short against the engine, meaning that the voltage going to the ECU was all wrong.

Power Engineering found this fault and corrected it for me - I would suggest if you have not already done so - have the Lamda sensor checked, and the voltage at the ECU.

Power Engineeing are very good and I am sure other companies mentioned here could also check the car for you.

Ken

 

cheers chaps took car to scooby sport and they found thw wires from the lamda sensor had burnt out so they fitted a new one but the problem came back after a road test . where abouts are power engineering and have you got there number

 

if you find the answer i'd love to know what is was. Mine is a MY93 WRX and does the same. one day it feels great with lots of performance the next day it holds back and seems not to boost.

if you find the answer pleaseeeee let me know

 

Power Engineering can be found here

When they sorted mine out it was during a rolling road tuning session - well worth doing. The ECU was receiving crazy voltages from the shorting Lambda sensor wires and we were afraid the ECU might be toast - however dsiconnecting the ECU and then connecting it again resolved the issue and the voltage going through the ECU reverted to standard.

It may be that you need to completely disconnect your ECU and then connect it again - probably best done by Power Engineering though as they can check that the voltages are correct.

The possible bad scenario is that your ECU might be damaged - in which case you will need to replace it.
If that does happen to be the case get in touch with me via e-mail ken@cianalas.co.uk as I am changing to a LINK ECU on Saturday and my current ECU will be for sale - it is an ECU from a Type RA and with that fitted and and a Mongoose exhaust my MY93 car (standard 240bhp) produced 287bhp on the dyno. See

Anyway good luck

Ken

 

just got another ecu today to try if it does cure it (cant see it with the luck im haveing ) i will let you know how i get on
