Wizard, I just ran across this note - I have a few files you may find useful (MEFI3 related): -- M9814A1.CFG is a text file with the locations and scaling of many data items -- DSNF9813.CSV text file with datastream information -- MEFI_Datastream.docx document I generated for the datastream -- 500HP...

YES!! Now *THATS* more like what I am looking for. This appears to be something used during development for the Lotus Carlton - I don't know what the similarities for the 4-cyl M100 turbo are, but it is a starting point. Now, to figure out what is in the Delco 26500 IC...

Thanks! --Gary

Has anyone actually traced out the circuit on the ceramic hybrid? This is what I'd like to see so I can understand what it is actually doing, and how to properly adapt it to different vehicles. I have visually compared the M100 turbo and non-turbo circuits, and the non-turbo is a simple resistor net...

I'm working with the Lotus M100 folks to come up with some replacement MemCals (ECM PN 1228707) but they are pretty much non existent at this point. Does anyone here have any information or documentation regarding the design of the Hybrid circuitry in the MemCal and what all it controls (i.e. knock ...

I'd like to do more with this, but I need information on the FMD, memory-mapped IO, Factory Test mode, and the ECM hardware. I'll probably work through a bit more of it anyway, but if anyone has info about these, send me a note!

M100-Euro-USA-Dasm.zip A few notes about these listings for the 1990-1994 Lotus M100 Turbo: First, I have no official information about any of the code or table scaling factors. This was all derived from looking at similar listings and analysis of the code. Many variables and tables I just made up ...
