Since some ECUs are starting to get more rare, I started a few years back to better understand their inner working and we have accumulated enough info to produce a schematic. We are now at a point in theory that we could convert EFI/V6 to turbo units but need documentation. I would like to create a schematic using Kicad and I need your help. www.Kicad.org is free software for electronic CAD. Your involvement can be small or large.
Various tasks could include
1) use a multimeter to determine where each of the 60 way pins go for example.
2)remove all components from each side of the PCB and photograph.
3) Sand down the top side to reveal the inner layer and photograph.
4)take the above info to help produce a schematic.
5)create schematic diagrams for the special items

If you are not experienced in this field, this is an excellent opportunity to learn. This is open to everyone.
