Your mission, if you chose to accept it, modify the code for a early 90's Cadillac with 4.9 engine and 4T60E (FWD) transmission. The main goal is to be able to use a 2-bar MAP sensor and provide the appropriate fueling, spark, and transmission control for this application. Boost control is not needed, but could be a welcome addition. Even better would be the same ability to use the NVRAM chip and applications for flash tuning. I further information is needed, questions are welcome.

Keep tuning my friends,

At least its a 64k bin. No bank switching to deal with.... If there is a definition for it somewhere and you can name some of the locations from that then disassemble it that would be a start. but yeah still a big job! Do you know the stock 4 letter code of the tune?

The BCC is BWYZ. I do have a definition file for this particular code but have not done any work with disassembly. I do want to learn but I am not sure this would be the best project to start with. I am willing to give it a try though.

Re: A challenge to all, code for bosting a 4.9 cadillac.
Attached is a disassembly of the bin you posted. Was done using M6811DIS and have included the control file for it so you can add any parts that are not included (have not checked all the routine have been hit).
Only issue is there are more than 4096 labels required so M6811DIS gives a heap of warnings - example is if you got to address DB11 in the dis file, there is a JSR command directly addressing a memory location rather than using a label. This means the code is not relocatable and will need fixing.
