Datalogs showing ignition timing dropping to -4degrees!
Posted: Tue Aug 31, 2010 5:57 am
Hi,
I am having a weird ignition timing drops. While driving normally, around 1500rpm with TPS around 8 to 10% datalog would show timing dropping to -4degrees momentarily and kicking back to the table values after awhile.
I've made datalogs on this problem and analysed all possible inputs and there are no weird spikes in other inputs. As the car picks up speed the problem goes away.
This happens every few days. What could be the problem?
2ndly, i see flickering of the data trace on the tables while datalogging is on. The flickering runs around the entire map is this an issue?
Attached is the datalog file
