Default Ecu
Hi again, its me, the pain in the ass...

another question for you all.......(i did a search with no success)

i have removed the ecu, and there is no sign of burn out....will be getting a new Fuel Pump relay soon, but, if it is the ECU thats at fault will possibly need to scource a new one...
ebay is devoid of such an item, and looked on here and piston heads..no joy...

ours cant be the only scoob with this ecu can it???

well, the ECU i have here has a red label, Marked
V9
22611 AB750
A18-000 RJ7 3927


its a 4 plug btw
Ok, anyone got any ideas

You will need a Wagon ECU i.e 1C, 3B, V9, V5 or 4B due to the WRX wagon having the smaller TD04 Turbo.
Saloon ECU will not be suitable as it runs the larger TD05 turbo so has different boost control.

Any of these ECU will work, infact most run the same maps but with minor mods to the running code as they matured.

LOL.. wouldn't be suprised if the info above was gleaned from one of my posts many years ago, as I have all these ECU maps/codes on file.

Does the car have an alarm/immobiliser, as the immobilisers normally splice into the fuel pump circuit.

immobilisers are normally 2 or 3 point i.e starter motor, fuel pump and ignition. it may not be re-connecting the fuel pump when de-activated.

I would try and see where it's been wired into, although modern alarms are quite tricky to trace as they tend to use all black wires.

"LASERLINE model 921K immobiliser is a sophisticated
electronic device for vehicle protection, which ensures very
reliable protection with a simple operation procedure.The
system consists of a control unit, LED/Receptacle and two
code keys.
The 921K immobiliser deactivates the main electric circuits
of the vehicle (starter solenoid, petrol pump, injection or
ignition coil...) and simply operates by a coded key that
must be touched to a receptacle on the vehicle fascia before
starting the vehicle."

Hi,

I have V9 - very good condition and fully working:

This is available but won't be listed on Ebay for a few days yet.

You can call me 0n *********** or check out my listings on Ebay where I am known as chrislloyd17.

Regards

Chris
