OK ballad2 i live in GSXR1000K8 world:).And theoretical thing about unifiyng.If we can adjust fuel amount for each cylinder to prevent lean condition for external cylinders then what for we need separate IGN maps for 1-4 an 2-3 Are there any mechanicali,or other reasons to have different IGN map?Also what do You think about installing 2 HOX sensors for 1 and 3 cylinder and tune cylinders as groups 1-4 and 2-3.If for each group we will have AFR in good range then we can unify IGN for cylinders.
I checked gsxr1000 K8 21H50-01. In your case IGN group1 and group3 are identical, while group 3 main difference is more advance
between 6.8% TPS and 25% TPS. You should take group3 as a base, while if you wish to have smoothness at low rpm you can
retain group1 rows up to 2000 rpm or up to 3200 rpm.
You can surely move a single o2 sensor from cyl1 to cyl3 logging values at different times.
It would be an interesting experiment.
Based on it the stock rates among different cyl could be possibly better tuned. |
