ECU's abound my friend. What exactly are you getting at? You want to R&R all of them?

Get a FSM if your going to do that sort of work.

i
was thinking my problem might be a hickup in my security or lighting don't know whether they have seperate ECU's and I wanted to know whether if you took the main ecu from a donor sc with better performance would my sc400 react with the same charecteristics ie: performance" and to get all the ecu's to be programed to each other is that a Lexus tech. only "ie:dealer" job????
