Link ecu to suit 1990 RS legacy

[ginganinja]

hey guys,

 

After a link ecu to suit a 1990 rs legacy loom. Is there any plug and play options available or is it just the wrx's that link make a plug in ecu for? Or would I need a wire in ecu?

 

Or is it possible to repin the legacy wiring to run a v3-4 wrx plug in link ecu?

 

I do have a possum link I could use but am considering getting a later model ecu.  If I use the possum link ecu, has anyone here had much experience with them? Can you get a good tune out of them?

 

Be glad of people responses.

 

Cheers

Plug and play is available (wrxlink v1-v2 is the same) and not that expensive for a new ecu. But they do come up sometimes second hand cheaper. I've got a base map to suit a bf5 g4+ if needed.

 

Could probably re pin or make an adapter but doesn't seem worth the effort.

 

Never played with possum links myself. Had one in my first Subaru and it run fine with the throttle down but was missing little things which would annoy me if it was a daily (unsure if it was tune or ecu capability but I suspect the later). A tuner told me it was more expensive to tune the possumlink because it takes them more time.

The newer G4+ G4X V1-2WRX plugins work on the first gen RS legacy, I ran one in my 1991 RS-RA and in my 1989 RS

Awesome! This is good to hear. Will look into a G4+. 

 

Yes, I have heard the possum links don't have the features new ecus have so its hard to get a decent tune out of them.

Yeah the Possum Links are ancient turds these days. Even an old "classic" G4 leaves them for dead.

The Possum Link is less advanced than the stock ecu of a 1990 legacy.
