== Tutorial ==

• 68HC11Checksum A detailed tutorial on how the checksum calculation works in the $32 mask. But it should be general to how most GM ECM's work.
• 2dTableLookups A detailed tutorial on how the 2d table lookups work. It explains how you can use the subroutine to do your own 2D table lookups.
