BC5 RS with Chipped W6 Ecu / What chip

[THUNDA]

Am having trouble finding out what chip is in my WRX RA ecu which runs in my RS BC5

 

Pulled it out to find some dodgy wiring and a speedlabs chip which looks like its been soldiered in my an amo

 

Emailed speedlabs nz, they cant tell me what type it is and cant tell me what it might be, as someone may as bought a chip for an RS BC5 and installed it onto this ECU without knowing its a WRX ecu

 

Swtich for the chip was unside down so when I thought it was off the chip was actually ON and the car normally runs relatively well, but with chip OFF it backfires under deceleration and doesnt perform very well / pickup is lacking -  but correct boost is created either way

 

Am keen on changing back to greys but have been warned that if the chip is tuned for yellows then the car could potencially run lean and cause damage quickly, as opposed to leaving in the yellows and it just running rich

 

So failing I find what type of chip it is should I just put greys in and see what happens or leave it? Im planning on getting a Power FC or Link and getting it tuned in the future so maybe just plug it back in and leave it untill then?

 

 

 

looking at pics of speedlabs chips in ecus  - mine looks upside down in the socket : /

If i understand correctly, the car runs satisfactory with the chip active, so why not keep boost at a safe level and wait until you are ready to go to a tunable ECU?

 

Or you could buy a 2nd ECU that suits 380cc injectors and do the whole lot?

 

There won't be any issue with it being upside down, it should be mounted to a socket.
