False KR?

i saw this on a Corvette forum...

At what rpm are you seeing the kr? It could be that you need to decarb the top end. I would pull some timing and try it again. If you are still getting kr at the lower total timing I would suspect carbon in the combustion chambers.

I had a similar problem last year, I was getting 6 degrees of kr at5500 rpms no matter what my timing or a/f was. After 2 cans of seafoam in the cylinders problem was solved.

..makes me wonder cuz i pulled 1/2 the KR i saw and ran again and still saw the same amount

also..i have no cat and an open borla..its VERY loud..not to mention i get the same amount of KR on a 120, 150, and 175 shot..i also saw about 5* of KR on the STOCK pcm..i mean..how can that be??..i have a pump and my injectors have plenty of room..so i dont think im really running THAT lean..im starting to think about half my KR is false..

Your engine is only like a year old, isn't it? I doubt there'd be that much buildup in such a short amount of time.

Have you tried running race gas to see if that gets rid of any of the KR?

not yet..im gonna try that tomorrow..if it doesnt make a difference..then its most likely false..some of it anyway..so i can lower the max KR a little..is there any other awy to see if its false???

damnit..its real :( ..i just ran a 50 shot and only got 2* for a real short while..im getting 11* - 12* the whole time on the 175 shot..damn..how much do you think 107 octane race fuel would take care of?
