G3 with G4 upgrade into v3 Wrx my97


Recommended Posts

Hey guys I'm looking at purchasing a G3 link with upgraded G4 software for my version 3 Wrx but I can't find any info on the internet about what extra sensors would be required to make it run correctly and how I could check if it's not a dud ecu when I go look at it..

I would put it into my car to test if it powers up when I go look to buy it, but what things should I be looking at on it?

Thanks Jordan

With out powering the unit up you can only look for visible damage. Looking for any signs the smoke might have got out. (it will smell very bad if it has)

We can do a full bench test of the unit if you wish to send it in for not too much money.
