Tools for Weber Marelli IAW ECUs
(as found in the Lancia Delta Integrale)
The grale-ECU (GECU) tools are provided free of charge but without warranty
or support, however I welcome feedback
about bugs found or desired features. As long as I continue to work on this
project some updates may be provided.
Many ideas inspired by the folks at PROGRALE
and the Integrale community in general. Hopefully in some small way I have

GECU REVERSE ENGINEERING
The following tools can be used to “reverse engineer” the binaries of the

understand 6800 assembly code and know something about engine
management systems then the disassembly
tutorial will give you everything else you need to figure out
exactly what the computer is doing in your car.
or get it all by downloading a single zip
- GECUdasm – the best code disassembly tool I
have used is provided free by Tech
Edge. I have also mirrored a copy of it here.
- Start-up control file - a starter control
file for the disassembler
- Disassembler control file - the control
file with basic info from the ECU
- GECUparser – a comment parsing tool I
wrote to strip the comments from the disassembled binary. (see tutorial
for why comments have special treatment)
- GECUadder – a comment adding tool I wrote to
add the comments back into a disassembled binary
- Start-up batch file – a starter DOS batch file
(helpful since the above tools are DOS programs)
- Disassembly batch file – a DOS batch file to
support the disassembler and comment parsing and adding
