Hello all,
So I just got my logger working and I have a lot of knock. Here is what I came up with this was in 2nd gear, 10 psi.
Rpms Knock Timing 02
2187 8 23deg .53v
3062 10 20deg .84v
3312 9 20deg .84v
3781 14 19deg .82v
4406 15 17deg .84v
4812 21 15deg .84v
5343 20 16deg .82v
6062 17 16deg .82v
6468 18 15deg .84v
In third I saw knock as high as the 30s I just did not log it correctly.
Fuel trims are, Lo 81% Mid 100% High 100% and they never move.
One last thing I put the wrong gas in the other day 87 instead of 93 could this make me have so much knock?
How much does running race gas reduce knock there is a station not that far from me that sells it.
