Toyota 1KD SOI adjustment

by **praga** » Thu Jun 18, 2020 3:52 pm

Hello

I hope you are well. I have been busy with this 1KD Toyota 3.0D4D Automatic. I am trying to adjust SOI. I think the maps are located at:

154DD 18x25 8bit
156CD 18x25 8bit
15A61 18x25 8bit

If i decrease the map values, the SOI decreases a little in some areas. Not throughout the rev range.

Can anyone confirm these map locations please ?

Has anyone got the conversion factor for this map (if it is the correct locations) ?

Thank you

Hi there! Did you figure it out? I know some other toyota diesel uses factor 0,2 -30 on main timing maps.
