Sorry guys but I've sold it today I got a good offer and took my losses

Yes please scooby ghost but the avcr is turned off atm so actuator pressure is all I'm running atm but I will try it just in case Can an O2 sensor cause this kinda problem?

Here's a few pics

It's non existence I belive. . . it's running an avcr wich I guess does the same job but without the stock one being there I guys the ecu has no clue of what's happening

Ok so I've installed new coil packs and a new maf and I still have the same problem :( Ive had the dash out and put a new CEL bulb in and I get code 44 Wich is the code for the oem boost selonoid malfunction abd it's obv it's been removed any way I can bridge the plug for now? Can this really cause a fuel cut I guess it could. . . and my best bet is to fix that fault code 1st. Just hope I'm not chasing my own tail and wasting money on it Cheers again guys

Haha yea it stalls :) but if it was broke then it wouldn't start either [emoji14] But I'm VERY sure it's the coilpacks I just want that full chat boxer noise haha

I tested the maf today with a multi meter and it seems to to reading but unsure as to how well My problem is now worse as it's now cutting at a lower rpm abd the ONLY 3 things that have changed is: 1. Cleaned maf correctly with electrical contact spray and alowed to dry for a day 2. Changed new spark plugs to the correct gap and plug 3. Coilpacks were inspected and literally fell to pieces in my hand Because of my problem getting worse and my coilpacks also I doubt this is a coincidence And will report back when I have coilpacks fitted Cheers

Ok sweet I get that :) BUT I don't think it's boost related as I can NOT boost past 0.6 bar I think this is my secondary problem :) I think that a sensor is broke somewere possibly the maf? I don't think the coil packs are my main problems either all tho I have i have a working standard set as it was my cheapest option for now From my research last night this is quite a common problem on subarus and is usually something to do with fuel grade and / or fuel delivery? I went fishing today so I'm not working on the car and I'm busy tomorrow with family. Is there anything you guys can suggest if I get time to do them tomorrow? Cheers

Ok cheers guys One problem tho the cut only happens when it's WOT The car is sorn now till I can get it working properly but got acess to my dad's boost bus (Sri t zafira) :) Ok so Savage, do you mean 100 each for the new age coils? If not I'll go for that I belive the jdm sti did not come with a cat? And I really don't understand why a bigger exhaust will cause any problems at all its just somewere for the gasses to go But maybe it's worth checking the O2? I'm trying to find a standard intercooler and hoses just to fuel out this problem I'm going fishing tomorrow to have a rest from it lol Ok to recap Fuel cut problem possibilities : Fmic and exhaust not accounted for in the map. Now looking for an original IC Coil packs are shot. getting new coilpacks and changed the plugs Fuel pump shot. Fitting my walbro soon Maf shot Cleaned and now drying Ecu shot Try a new ecu Loom shot Well. . . Low boost (0.6) problem Actuator stuck It's now freed but it's hard to move still Avcr not working. Try an MBC Turbo broke. Well. . . Any more ideas guys? Sorry fixed language :)

I rekon were found the problem 3 out of the 4 coil are bust either cracked or bits missing What's my best option now then New coilpacks or the coilpacks convertion The working one had this on Cheers guys I feel were getting closer to fixing it

Yea but I've phoned a few subaru specialist they rekon the maps not too important atm they think it's the MAF Just to clarify the only real mods are 3" turbo back FMIC Avcr The rest is swallox unfortunately the guy must be the biggest lier that has ever walked the earth. . . Today I've got new plugs that I'm gapping to .65 I've cleaned the maf and just letting it dry Maybe even put in my new fuel pump I'll see if that makes a difference

I posted a photo of the ecu without a case it is standard if I haven't I apologise I thought I had but it is a standard jecs item

Cheers savage I'll answer all your questions tomorrow but it all look ok from a generic turbo setup I think the ecu is the problem tbh I personally think it's been taken out before I bought it and replaced with that one

Ahhhh makes sence as I've found in the glove box the necessary guage and a few other guages including 3 other boost guages ?! Wtf haha Yes it is a catch can And I've have confirmed them as stick injectors :)

Split in the hose but seems to seal ok Standard injectors? Wtf is this? It's missing 2 cables out if it I think and has lots if earth straps lol It ends here General engine bay pic for you eagle eye dudes/gals Cheers guys :) Can i getter a quite DV as it's horid and quite annoying

I'm in Southampton fella but can travel . . . . . Well depending on how it gets on lol bu I've just looked and I infact have grey injectors wich is good I suppose as it's on standard management I have some more pics for you guys to look at :) I'll post them in a sec

Sweet really thinking of breaking it atm not sure how much I'm gonna throw at it before I see results :(

Ok so I've had a play today and found a few things I can not do the diagnostics as the CEL does not active like it's not there The ECU is a standard unit The apexi avcr reads a few things such as: Boost (correctly) Rpm (not correctly) Kmph (not correctly) Injector cycle (unsure) Today doing a few runs it reved fine in 1st and 2nd again but at any other gear @ 5500 it cut again but seemed to go past it if I'm not nailing it When watching the Kmph on the avcr it spike when I was steady on the throttle is the speed sensor going? Tomorrow I will do the spark plugs and clean the maf as it hesitates abit in 1st on WOT Here are some pics from today I'm also in mega need of some head lights and rear light if anyone's got some going or know we're I can get some CHEERS AGAIN GUYS!

Ok so I've had a very quick look before I go out and I've found my boost problem it's all plumbed into the apexi boost controller, so with this not working because the apexi ecu has gone it's just running off waste gate pressure 0.6 bar? Seems plausible

That's my thinking fella but we will investigate today :)

Wow cheers for input already :) got a few pics now But there pretty bad lol ill get more detailed pics tomorra

No i havent im just breading about that i poped my head under there and see a load of chavvy leds and a few other diy bits but thats my plan tomorrow

haha cheers dude im quite mechanically minded so but im in no way trained but the boost maybe that just that its running on actuator pressure? what exactly would you like pics of ? ill get a picture of the inside of the ecu but it did have pink writing on but no way can what it says be made out ill get pics of the engine bay i did notice that some think dont look standard for example the maf has a logo on or maybe just a sticker lol

Hi guys! so i have just aquired a wrx sti my95 going by the chassis number and some online recourse you will have to forgive me as im used to working on toyotas and nissans ive never worked on a subarus untill today. . . . ok so i picked it up and drove it home 1.5hrs and on that drive ive noticed a few Dodgy findings the cars only running 0.6 bar the car will rev quite high in 1st and 2nd but in 3rd,4th, it will only rev upto 5000/5500 untill what i can only describe as boost cut the car has alot of upgraded parts but the ecu looks standard, he mention that it is an upgraded ecu i suspect a lie and the loom behind it is butchered he mentioned it had yellow injectors a bigger turbo , 3" turbo back apexi FMIC and "loads of other bits done to it mate" he showed me an old map of 300 bhp witch i think id be lucky if it was 100 bhp haha it has an apexi boost controller but its either missing some bits or turned off and its not doing anything bit work as in lights up and has a menu. . . . . . . . . . . my question is how i can get it running to its standard 240bhp ish performance and to find out why its not revving correctly any ideas would be appreciated im reading up on alot of threads/post here aswell i guess i always have the option of breaking it for parts but its my 1st ever subaru and would prefer not to leave with a bad taste in my mouth i can take photos of anything you guys request and try give any more info you require cheers guys :)
