Samppa Posted December 28, 2017 Report Share Posted December 28, 2017 Hello, I recently bought a car that has knocklink g4 fitted in it and it's showing green most of the time, even when revving higher but when I'm driving steadily at 100kmh and about 2700-3000rpm its flashes red sometimes, I'm concerned because I don't want any damage to the engine. Any suggestions? The car is subaru forester 99' 2.0 s turbo. Also, the engine is running fine and there arent any unusual sounds when it flashes or anything Quote Link to comment Share on other sites More sharing options...
Simon Posted January 11, 2018 Report Share Posted January 11, 2018 Best bet would be to check with an external listening device. I suspect it is fine but you wont know unless confirming with another listing device. Quote Link to comment Share on other sites More sharing options...
