Injectors

I started comparing the injector latency table on my evo x with the data available for id1000's (which I am planning to install). The battery voltage reference points are different on the table in ecuflash vs the data provided by injector dynamics. what would be the best approach to getting the right data to input?

Make a linear interpretation to the battery voltages you need. For example, the ID 1000 deadtimes I've got are:

43.5 psi differential pressure:

Voltage Offset (uSec)

8 2600

10 1675

12 1240

14 990

16 805

Let's say you needed 13.3v: You start with the table breakpoints on either side (ie. 12 and 14). The range is 2 (14 - 12), and 13.3 is 1.3 (I got that from 13.3-12), along the range of 2, or 0.65 (65%).

The range of the Offset values is -250 (upper - lower or 990 - 1240). Multiply the .65 x -250 = -162.5, and add this to the lower Offset value (1240), to get the linear interpolated value of 1077.7

Here is the formula in another way:

For X1 < DesiredX < X2

and F(X1) is the table value for X1, and F(X2) is the table value for X2

F(DesiredX) = F(X1) + (F(X2) - F(X1)) * (DesiredX - X1) / (X2 - X1)

F(13.3) = 1240 + (990 - 1240) * (13.3 - 12) / (14 - 12)

F(13.3) = 1077.5

Another option -- can the table breakpoints be edited to agree with the ID1000 data?

I know that this is going to sound completely counterintuitive, but when you're dealing with the Mitsubishi ECU the scale and latency values won't be exactly what ID have provided. The general technique of scaling injectors involves adjusting the scaling value initially and then performing logging at idle as well as at constant cruise. What you're looking for is the sum of the LTFT and STFT. You can then manipulate the latency values and the scaling in an iterative process until the sum of the trims is as close to zero as you can get it. This process is covered in detail in the Practical Reflash Tuning course if you want more information.
