Map SOI

by **Bart** » Sat Nov 10, 2012 2:51 pm

Hi to all.
I am looking at a map Bosch EDC15C7.
I did not understand what are the values on the X and Y axes of the map SOI.
The Z axis is the degree of advance (of beginning injection diesel)?
With which factor are corrected the axes X, Y and Z?

Value:
- X axes: 0 100 400 600 800 1000 1400 1800 2000 2200 2600 3000 3400 4000 5000 6000 6500 7000 7020 7030
- Y axes: 0 500 600 1500 2000 3000 4000 6000 8000 10000 12000 13000 13500 14000 16000 18000
- Z axes: to 0 from 4098

Thank you! :)

PS: how do you attach images to my posts? Thanks! :)

This is NOT a SOI map. It is Injection Duration map.

Sorry for the confusion! I am a principainte and this is my first map ...
So the Z-axis are milliseconds opening of the injectors? The values in the table should be multiplied by some correction value or are already real?
Thank you!

I`v similar problem - and i dont want starn new topik.

This map seems like SOi 16x16. Adress - like in video and pdf for SOI.

You have selected right map, now you need to find X and Y in the bin, also use correct factors. Z is degrees BTDC when start of injection begins...

Both SOI and duration maps have engine speed (rpm) and iq (mm3/i) in their axis in every EDC15. Although some maps don't have the axis adjacent to the data.
