Personally, I find it better to start from scratch and build a new ECU
from ground up because I do not get boxed in by the limited information
available.  One could also use some off-the-shelf industrial
microcontroller with your choice of CPU and full documentation.
Wouldnt it be great if we could actually review the software source
codes for those GM boxes? Likewise, I think it takes too much trouble to
decompile the firmware to produce the source code.  Whaa?  The guy just
wants to change a carburetor, and we are talking software??  Sometimes,
I miss the good old days when we had a collection of main jets for a
hobby.  

Cheers,
alex samson
