50% larger fuel injectors |
so cut bottom cycles to 66% of original value - preboost #'s |
|
|
|
Running misu td05 - boost comes on at 2000 RPM's - turbo runs out at 5500RPM's |
|
|
When looking at the stock boost meter, you can divide the distance between idle and top of the red into thirds. Yellow, boost, should begin at approximately 33% mass airflow. |
|
|
Since I'm running 50% more fuel and 100% percent more air, I want to calculate for "equal to stock" fuel to 33%(31.25) on the map and rise to 200% fuel flow at 100% massflow. (Note: I'm running double the air flow.) Based on larger injectors, should be 133% of stock number. |
|
Explain: Say stock fuel flows at a number 6. I added 50% more flow which puts it at 9. Getting the flow 9 dwn to 6 (for idle up through pre boost) I want it to flow 66% of 9 which equals 6. |
|
|
At the top end, since I have doubled mass air flow, I want fuel to flow at 200% of stock(6x2 = 12) for the highest number in each RPM row. (Numbers in BLUE below) I added 50% bigger injectors so base flow is 9. |
|
|
So I need to adjust fuel map numbers to 133% of base flow. 9 + 33%(3) = 12. Make sense? |
|
|
I then count the columns between the highest value in each row, subtract 66(last preboost value % ) from 133 (highest boost value %) to get 67. I then divide 67 by the number of columns to get the percent change needed to evenly rise from 66% flow to 133% flow. |
|
|
For the values past the highest value in the row where the highest value isn't at 100% massflow, I clculate the percentage drop between each column and starting with the first value past the highest value, change per percentage. |
