When adding fuel or removing timing do you have to do the exact same adjustment to all the RPM ranges or can you just do adjustments to the higher RPMs ..... and what about WOT Spark & MBT Spark ...

[gizmodo]

That is the reason they give you the different RPM bands, so you can adjust differently in each. What you need to do is make some pulls while logging, add/remove fuel or timing in the RPM bands where it needs it, and try again.

Same thing with WOT spark. Leave MBT spark alone.
