Just bought a STI with Link G4 installed. Â What is the function of th engine lamp on the dashbord togheter Link ECU? Sometimes it flashes on high revs, also intercooler waterspray lamp flashes somtimes, car has fmic, no spraying connected to that. The ECU is also locked by a former tuner, I was thinking of getting rid of the tune. Then start over from scratch by my self. Is it difficult to roadtune with G4? I have some experience from opensource tuning with Subaru.
