Guess that's why I could not find them. I presumed cold start was handled like my old 528... should have known they'd change the config on the motronic 3.1. I suppose that means that the length of time that the regular injectors are operating in cold start mode is handled by a thermostat somewhere. Any clues as to which one that is?

Correct, no cold start injectors. Normal injectors are held open longer during cold engine conditions.

No such thing as far as I know. Maybe some of the long time DIY'rs might know of something but I think the 'cold start' is handled through the DME with the normal gear.

'88 750iL

Can anyone give me a description of the location of the cold start injectors on a V12? Originally I had thought they were on the firewall end of the manifolds, but these are the intake air temperature sensors. Any help?
