WR1 ECU in STi
 

Hi,

bought a WR1 ECU and exhaust to put in my 03 STi,just looking for comments on if it will work ok?

I can't see why not,but anybody know for sure? or do I have to be the guinnee pig

thanks,

Have you added the rest of the PPP parts as well? If you fit the ECU without these I doubt you will gain anything, or could even cause damage the engine if the Walbro fuel pump is missing etc

Anders

I have the walbro to fit also,forgot to mention that

as far as i'm aware that's all that is needed?

thanks,

AFAIK the full PPP parts list is:

Walbro fuel pump
Prodrive 100 cell CAT open-neck downpipe
Prodrive back box
3-port boost solenoid with revised boost pipes to avoid heat from turbo
Better intercooler Y-piece
Revised ECU map

Anders

why would anybody buy something and then ask if it will work? did you not do any research before you bought the thing? is the wiring loom the same? is the pin out the same, can the ecu be reprogrammed? your 03 STi is certainly not a WR1

the STi isn't far from a WR1,as Anders has just pointed out

thanks,

The ECU will fit but boost control will be screwed using a 2 port on a 3 port map.

is it just the wr1 that had the 3port boost solenoid or was the 3 port fitted to all sti ppp`s?

Just the WR1.

I have the boost selenoid also,will there be no boost if I don't fit the new selenoid?

I just fitted the ECU,and replaced the chip in my key for the cotrrect one but the can't wont start...does the key need re programming aswell?

thanks,

I just found out it's because I dont have the transponder,If for some reason I can't get hold of said transponder.is there any other way around it?

thanks,

guy's I need something confirming,I have the chip fore the WR1 ecu,what is the black box that goes on the steering column called?

the transponder,or receiver? or none of the above?

also is there a way to have it re-programmed if I can't get hold of the black box?

thanks,

yeah take it to subaru and pay £57.50 to have your keys coded to the ecu.

the guy is having trouble locating the receiver box,I just had a look at my car,is it the silver box held via 4-6 allen bolts?

also anywhere in the UK I can buy the prodrive 3 port boost solenoid?

thanks,

I recon your local subaru dealer would be able to order one, or any ECUTEK tuner as they are a common upgrade when you remap.

ok thanks I'll give Subaru a call tommorow,any ideas on the immobiliser receiver?

thanks again,

Don't goto Subaru for the 3 port, they'll fleece you for about £200. Try to source a 2nd hand one.

I had a look around and can't seem to see any for sale,I found a load of US sites selling them at around $100 so figured they wouldn't be too much new over here.

the receiver has now arrived,I just need the 3-port... does it have to be the Prodrive one or can it be any aftermarket 3-port?

thanks,

desperate for some input here....


thanks,

You should be able to get 3 port solenoid from Bob Rawle: BRDevelopments

ordered one of him last night... so I'm all set

ECU fitted and now running,waiting for my Prodrive 3-port to arrive,and then onto fit my sports cat...then i'll let you know how it drives...if anybody is interested?

If you fit all the parts, you should be making same power as a WR1 :thumb:

ECU
 

My ecu in my wr1 has just decided to quit on the autobahn... Got a tow home, ran a diagnostic with no connection to the ECU.
Found a second hand ecu but is there someone that can reformat or repair my old one?
Is it a straight swap key in and go job or is there programming involved?
Thanks in advance.
