There's a bright fellow, name of Fred perhaps, maybe in Gothenburg, who must know LH2.4 well enough to write his own fuel maps for the turbo version used in 7/9 cars, or anyone who's dropped a b230ft into a 240. You can find him over on TB. All I have done with the various 240 LH ecus is trace their input and output circuits so I know more about how they can interact with what they are connected to. The output driving the injectors on the 561, 563, 933, 951 models is a simple NPN bipolar transistor open collector with an RC snubber and back-emf diode.

The brains are on the eprom of course. I'll leave disassembling that to the performance chippers. I just want to know how to fix them, and how to tell when they're broke.
