Hi everyone, I have a question as to what ECU should go to my car. I have a 1975 porsche 914 and I'm trying to find a new computer to put into it. I have two different ecu systems. They have the same numbers but the letters at the end are different. I also have two different jet systems and I need to know what jet system goes to what ecu. I am not sure what jet systems I have for it but I know one has an open tip and the other closed. If you have any advice as to which one is better and which computer works with what jet system thatd be awesome!

I think this was answered in your prior post here...
