just bought a import wagon 2.0t (94) needing exhaust so fitted decat from turbo back (lambda sensor removed unsure if it needs it) first time i drove it was when the exhaust was fitted and the problem i have is it doesnt seem to be boosting propaply (not getting full power) seems to be holding back ad splitters abit? any ideas thanks guys.

 

It does need a lambda sensor which is fitted in the manifold/headers, I suspect you have removed the cat on fire sensor which it doesnt need.

Best think to do is check your error codes and see whats going on, if thats all ok get a boost gauge and ee what boost your getting.

How to check error codes.

Welcome to scoobynet.

 

its got boost gauge and boosting around 0.5 ,

 

hi iv got full de cat system on my wagon and the oxygen sensor is fitted if this is not fitted the ecu wil get false readings hense poor running when fitted the light comes on sometimes but only when your giving her some stick and only briefly then goes back off but yep it should be fitted mine is boosting around 1.3 bar safely but i put td05 turbo on mine

 

Chris what ecu are you using to run that boost?

 

thats a prob i got its a 3b standard but it has a super chip wired into loom she will go more but you start to get fuel cut im going to be changing ecu for a v4 mapped one 4 plug type which should suit the tdo5 turbo

 

How long you been running that setup thought it would just go bang.

 

a long time now i think she must be around 290-300bhp mark but thats its limit on standard internals so iv been told wil find out def when i get new ecu remapped on rolling road couple people in saloon wrx tried having a burn but was all over them and left them so must be up around that mark

 

What other mods you got?

 

got full decat system ,air filt , super chip , boost controler, fitted tdo5 turbo as wagon have tdo4 standard (import model) im sure uk spec have tdo5 ,fitted boost gauge , turbo timer, brake caliper upgrade

next upgrade remap ecu/ fuel pump/

 

You still got the slanty cooler to.
I have a 95 wrx wagon with td05, walbro pump, decat and z4 ecu with 1.1 bar chip. Four pot brakes and facelift front end. Got facelift cooler to fit when I get time.

 

where did you get your z4 ecu and are you fitting the sti type cooler and how is this done ?

is that the z4 ecu with internal chip and remap 4 plug

 

Got ecu from on here or ebay cant remember which, it has the chip fitted internally, theres one for sale on here £90, Just fitting the standard one as the sti ones are the same size but silver unless you go for v7+ but these are a pain to fit. Im hoping mine will just be a straight swap with the new brackets. If your not looking for massive power someone on here is selling chips for £100 which he will map for your mods and plug into your ecu.

hi i had a wagon for my first impreza i fitted a full decat, td05,front mount, hks induction,walbro fuel pump,standard ecu with esl mappable chip, i got 302bhp an 300 tourque and 1.34 bar boost it was an animal i had a bit of a ding dong with 1 of those amg63's they are 500 an odd bhp an just under 500 tourque an i was side be side with him so i didnt do to bad considering the 6.2l engine he had an the power its got, when you get all your mods get it set up right by a good mapper who knows what hes doing it will pay off in the end trust me ive got a friend who fitted 1 of those pre-mapped chips in his saloon and 5 gear boxes an 6 engines later he relised it would of paid off to spend the 500 quid to get it chipped an mapped proply, gabbo the sensor you had taken out your exhaust its a cat on fire sensor which you do not need i would say check your acuator an check your boost lines plus give the boost controller a clean out which you can do using brake cleaner there is a thread on here explaining how you do it,PLUS WHILE IM ON HERE IVE GOT A 93 STI SALOON IN BLACK FOR SALE IF YOU KNOW ANYONE WHOS INTERESTED ITS STILL RUNNING STANDARD POWER BUT HAS GOT A FRONT MOUNT,WALBRO FUEL PUMP,FULL DECAT,K+N INTUCTION KIT IM AFTER 2500 QUICK SALE PM ME IF INTERESTED OR YOU NO OF ANYONE CHEERS

 

I dont think the chip caused 5 gearboxes and 6 engines to fail. I would put that down to being R.A.F.

 

trust me it did the chip he put in was making his car boost to 1.5 bar which was causing him to chew up gear boxes and blow pistons he even had forged pistons an crank in 1 of his engines and even that 1 blew, all im am saying is if your gonna spend money on your car get it chipped and mapped proply it pays off

 

I agree with last thread iv heared the super chips are a bit dodgy mine was already on that why im looking for diff ecu and get a proper map done to suit my setup got couple more mods to do first befor though did you have to do any mods to fuel system ect

 

I also have a MY94 SA wagon. running full decat, VF34, 440 injectors, 255 walbro, induction kit, standard slanted intercooler (good for 340bhp) all supported by a Unichip Q+ fully mapped by DSAutomotives on V-Power on 1.1bar and running like a dream at
314bhp and 360ft lb. If your car is set up and mapped propperly you will have a different car. As above cat on fire.
