Hi all

right I have a 2003 impreza sti and I am starting to wonder if its been remapped

when I bought the car it had the following mods done that I know of

blitz nur spec exhaust and heat wrapped full decat
and a turbosmart bov

and some 19" wheels and aftermarket splitter and winglets " I know these have nothing to do with my question but my point with this is the owner before last changed some things to aftermarket on the car so what else has been done"

the guy I bought the car from only had it for a couple of months as his second car for a fun run around and was selling it when he relised the fuel bill
and didnt really know much about impreza's so I he was no help in telling what had been done to the car.

recently I installed a brand new set of prosport JDM stepper gauges into the car.
and my boost gauge is reading between 21 and 22 psi under boost which converts to 1.5 bar
then I read the standard boost for a 2003 STI is around 1.1 bar " am I correct in saying that ? "

also if a blob sti had a decat fitted without a remap would the CEL light come on
as my car has full decat and the CEL is not on.

TBH I hope it is remaped as then I dont need to get it done which I was planning LOL

any help or opinions would be appreciated

 

if it has a decat and its not been mapped this can cause overboosting which may explain your 1.5 bar.


when i decatted mine prior to a being remapped it didnt throw up a cel light

 

Newage? It should have.

 

My cel light didn't come on , but I took it easy until remap.

 

Yup and the cel didn't come on drove 20 miles decatted until it was remapped

 

I would suggest getting the car on a rolling road and have fueling checked out that way you can find out if it has been setup plus it gets a health check too.

 

I would get it checked, just to be on the safe side TBH.

 

If a mapper plugged the ecu into his(or her) laptop, would they be able to tell if it's been re-mapped then?

 

Yes, if you have an OBD equipped car. Pre OBD, then the ECU needs removing and checking.

 

Sorry for silly question, but what does OBD stand for, and how would you know if your cars "equipped" with it...

 

On Board Diagnostic socket Cliff, the later cars from Bugeye on for the UK market will be OBD2 standard compliant and the JDM cars from sometime into the Blobeye cars.

Before that if they had an OBD socket then they were just using Subaru's proprietary communication protocols, hence why you can plug a generic code reader into the OBD socket but nothing would happen.

On your Blobeye Cliff the socket is at the bottom of the steering column / lower dashboard.

 

The blobeye's fine Ty. I asked the question because I wondered if that would solve the op's question, and I've got an old classic to run around in and wondered if it's been tweaked too....thanks for the info

 

As Ty said the Newage cars have the OBD 2 compliance.
The JDM/UK Classics from Sept 98 (MY99) had the OBD socket and it was also fitted under the steering column. It's were the PSI3 units, code readers and mappers plug in.

You don't need a code reader per say as they have built in diagnostics by connecting the green and black connectors for certain applications, also under the column. A search on here will easily get you the "How To" Guide.

 

Ok,cheers. I'll have a read

 

cheers guys for the reply's

Yea I will defo get it checked out
there is a rolling road just down the road from me at wallace performance but I would only trust them with a rolling road and nothing else.


I was waiting until getting a carbon induction from tegiwa and a aftermarket top mount intercooler before getting the car remapped.

 

Why are you wasting your money on that crap the sti top mount is fine and the induction kit will do **** all.
A decent panel filter is what you want and please tell me its not an eBay top mount.

 

Hi RA Dunk you are from around my area and been into subaru's much longer than me mate
could you tell me anyone I can trust near aberdeen to do a remap on my impreza STI as I would not trust wallace performance to do a remap as I have heard horror stories about them from people who actually took there car to them.

I was planning to go to andy forrest but thats a fair travel to get to him
so is there anyone nearer aberdeen that is good at remapping

 

Its not for performance gains that I am wanting them for tubbs

its purely for cosmetic reasons mate
I want under my bonnet to look exceptionally and really nice
and want carbon and lots of polished aluminum and blue silicone.

the top mount I have looks a bit scabby so I was wanting another top mount that is new and looking shiny bud.

 

also here is the top mount I am thinking about

What top mount is it though. You may be causing problems. Please tell me its not an eBay special.

 

this is the one right here dan

http://www.tarmacsportz.co.uk/GB/WRX.../WS-TMIC_.aspx

also here is another one as well

http://jperformance.co.uk/subaru-wrx...tmic-p-87.html

but the top one of the two which is the one I am more inclined to go for

 

Fmic you tool

 

LOL Dan both links are for top mount intercoolers what you going on about a FMIC for FPMSL
I dont want a Fmic incase I get a little bit more turbo lag and a Fmic will not go with the tegiwa carbon induction kit I will be buying mate.

 

If you buy a tmic for 700 quid because its shiney you must be retarded.

A decent fmic properly mapped creates no more lag and improves the engine bay look too.

 

Not retarded tubbs just can afford to buy something like that with out thinking about how much it costs.
and the second one that I posted the link to only costs £206 as well

TBH I want a japspeed Fmic but I want the tegiwa carbon induction kit more.
its a pity that they can not go together as the carbon induction kit blocks the parts of the inner wing that the Fmic pipework goes to.

 

Crapspeed but want pointless Induction kit......I'm out your're beyond help.

 

Hold on a second tubbs

Was it not a crapspeed fmic on your blob eye that you had ?

 

Was it **** it was one of Harveys hdi kits

 

Ok cool
How would you rate it was it good and does the pipe work on the induction side
Go in the same place as the japspeed one

Do you have any pictures of around the airfilter side you could post for me to see please

 

mine was in the inner wing.
id get some proper advice from your mapper before you buy that rubbish if i was you.
