1. Increment (Coarse) Value in the range below by 3X



2. Increment (Fine) Value in the range below by 6x



3. Increment (Fine) Value in the range below by 2x


The ROM is: 20080816_lean.hex

4. After doing some logging, the following point had a knock:


5. So I changed the area (denoted by the log) by Decrement (Fine) Value by 1x

7. So I Decrement (Fine) Value by 1x in the following cells as pointed out by the spreadsheet:


8. I noted that at 800rpm, sometimes my rpm drops quite low. I tried this change:


The ROM is: 20080816_lean3.hex
