This is the symbolic and commented source code for the DSM E931
and E932 ECU. To assemble "standard_E932_E931_source.asm",
download the telemark assembler TASM from http://home.comcast.net/~tasm/ to the same directory and execute asm.bat from the DOS prompt.
The assembler will produce two files: standard_E932_E931_source.lst
is a line by line listing of the assembly with addresses while standard_E932_E931_source.obj is the 32KB binary image to burn
on EPROM. Default setting produces the E931 standard binary image
Required file, not provided (from http://home.comcast.net/~tasm/): TASM.EXE, Version 3.2
Contents: standard_E932_E931_source.asm
Assembly source file for the E931/E932. See notes at the beginning of that file for more details. Default setting produces the standard E931 EPROM image.
asm.bat
Batch file to assemble standard_E932_E931_source.asm
standard_E931.bin
Binary file read from an actual E931 EPROM. Assembly of standard_E932_E931_source.asm using the "E931" setting should produce an identical binary.
standard_E932.bin
Binary file read from an actual E932 EPROM. Assembly of standard_E932_E931_source.asm using the "E932" setting should produce an identical binary.
standard_E931.lst
Assembly listing file for the standard E931, usefull if you just want to edit an EPROM image without assembly..
standard_E932.lst
Assembly listing file for the standard E932, usefull if you just want to edit an EPROM image without assembly..
tasm6111.tab
TASM compatible opcodes for the E931/E932 ECUs. Works with the provided source files. Might be incomplete if you want to use something not already used by the standard code...

ECU Stickers

There are three parts of the ECU label stickers to make a point of:

• The Mitsubishi Motors (MMC) number
  • Starts with "MD" or "MR"
• The Mitsubishi Electric (MEC) number
  • Usually starts with "E2T" on ECUs
  • Usually starts with "G1T" or "X4T" on TCUs
• The last letter of the MEC number
  • E = eprom
  • T = one time programmable (otp)
  • M = masked
  • A = ???
  • " " (blank) = maybe eprom for 90 ecus

Idle Adjustment

Maybe should be in another article?
