Re: quick question on powerpc code
First line loads a pointer to r3 Second line adds offset to pinter to r3, and than data from that offset is stored to r3. PPc code can use only 16 bit addressing and makes full address out of 2 commands I have another quick question, How to set up in IDApro r14-r17 registers with fixed values as in ...

Re: Logger improvements
I can only suggest for functionality, GUI design is totally upto you. More RAM parameters, that are needed for tuning, scalars for table lookup, and more knock data. Mode AE command for realtime control, like AFR, spark, engine speed and so no. Some crank relearn logic will be great too. I have some...

Re: E67 to T87/T87A TCM interface needed
From utilities->patcher original file->select bin when bin is opened you can edit tableseek from settings->tableseek Than you can add an entry just like configuring an xdf with different options. the main difference is that except absolute address it uses tableseek string. You can seek absolute or r...

Re: E67 to T87/T87A TCM interface needed
It wasn`t that hard once you know the pattern.
Found there is 2 main revisions of t43 code, not sure how to differentiate unless open in patcher, early style is labelled t43-0
later style t43

Re: E67 to T87/T87A TCM interface needed
Did some changes to e38 tableseek file, and now it will find the TX and RX tables stored in OS for any e38 e67 bin. End of table is open, so user needs to figure where it ends, Usage will be for display mainly.
Extract file to XML folder overwriting previous versions.

Re: E67 to T87/T87A TCM interface needed
Tre-Cool, once I map some of the code and see what is needed, I can add some tableseek logic to find it on any e38 bins.
Currently you need to trace it in ghidra from start of calibration offset for CAN RX/TX settings.

Re: E67 to T87/T87A TCM interface needed
If I counted correctly this is where bytes are stored from that message, r31 is the offset they get stored in numerical order. Now tracing down to individual bits will take some time, due to ppc crap code. Here is how bits are copied for first byte , r4 is the bit position, some bits might get inver...
