it's proprietary
Suzuki never published it ever. (old tech1's , are the exception and rare as hens teeth or long ago DEAD)
they SUZ, sells it, but just who will pay $ 1000s to do that, no tool maker , supports it for this reason. none.
(it's a big up front fee and like $4000 every year fee)
So any wonder Suzuki is chapter 11 here and in Canada? could it be, crap support, my guess is yes, IMO.
there is only one hacker doing this. and like 54 markets of PCM , potentially, just in usa there are 50 ECU/PCM/TCM and world wide, way more.
that 1202 is the ( topology , mapping) for your ecu.
you can capture the serial line data off the tools
even the teck1 one, you can do that. see all outgoing commands and responses. and check sum, methods.
this is how it was done, and code dis-assembly too.
all this is hacking, and will have rough edges.
and is far better than what suzuki offers.. no lie.
the protocal is super simple, i have it on my hack page.
eg
0x13 0x04 cmd , CS [CheckSum) ( line command syntax)
Checksum is calculated by this math: 100 - ( 13 + 04 + cmd) (hex math !) Rule: the CS must add to Zero , not including the CS itself.
Below are all CS values in column 2.
the trick, is the add to zero calc. making that happen.
the mapping is insane complex.
you must know the actual memory index code that maps a specific PID.
this is super hard to get , with no TECH one to capture this.
may be over 50 mappings world wide.. even JDM ecus' etc.
a Tech1, hacking 101
you tap into the single serial line with the special scan cable for chevy, (you have one)
then you run a dumb terminal programm, set to the correct BAUD rate
then give commands with the tool and and see all response or your terminal. RX screen "RealTerm(
