ECU info/help needed < im putting a wrx engine in a sport>
 

right first off the good news is ive got all the wires out of the wrx <my93/94>
bad news is the ECU on the sport has 3 plugs the ecu on the wrx has 4
i wanted to just add the extra wires needed and just change the ecu but it dont look like i can do this,

any info or help would be happy to hear from you

the sport ECU is a D3 < 3 CONNECTING BLOCKS>

the wrx ECU is a U8 < 4 connecting blocks>

anyone???

It would probably easier to get the loom from the WRX


None of the plugs fits the WRX ECU ?, I take it you were hoping to use the existing loom and add only the extra wires. Sounds like a long job.

I would prob pull the loom from the WRX and run that in, otherwise its a long job with a wiring diagram. You maybe able to extract the pins from the block and re-crimp, but it often takes a special tool to pull the pins from the connector block.

ive got the loom so will see what looks easyest

What year is your car ?

although a fairly costly option, considering youve just forked out for a donor wrx, you might want to look at running an aftermarket ecu and getting it mapped.

could take away a lot of the pain of switching looms

It could be a simple matter that the year of his car simply uses a 3 pin ecu, as 97/98 cars did.
Early pre96 cars used a 4 pin connector.

Engine choice will dictate a lot.

IMO,you will have to transplant the wiring loom from the wrx.

my car is a my00


oh and no this was the cheapest option lol cheaper than even buying a secondhand sport engine lolol

what year is your new engine, loom and ecu from?

Your shell and current sport loom is MY00?

i think i read that the engine and loom are 93?

the engines out of a import wrx <my93/94>

You need to create a loom adaptor then..

You need a wiring diagram from the sport and the turbo wiring diagram..

93 - 94 is different too.. does the crank position sensor have a cable coming from it, or is the connector on top of it?

will check tomorrom in the light, the project is coming up to the stage of sorting the wires so keep the info comming guys

cheers
