QLCC : Flat spots in MAC12 Timing
Very interesting comments on the MAC12 timing map.
With the guidance of Scott Mo. I have remapped my MAC13 timing to a
combination of MAC12 and MAC13 derived values.
I advanced timing low down, and lowered the values at high
boost RPM by subtracting from the original MAC12 map to compensate for the
increased boost level.
I have a plotted the different timing maps in 3D, would appreciate
some pointers on how to identify the flat spots and what remedies you
suggest, or if you wouldn't mind a copy of the modified timing map
that you run.
IMHO optimum timing map is essential.
Any help will be appreciated.
89 200T Durban South Africa.
Remapped MAC13A with cockpit adjustable wastegate for testing (will
disappear shortly). Still getting a bit of knocking somewhere, busy
constructing a visual knock indicator .
