So Paimon your taking certain addresses available on the HSCAN bus and then putting it on the MSCAN bus and then prompting the information display to show those addresses? Is this how all this works?

Essentially. Basically what is happening is that I read from the HSCAN, save the data. I convert the data to a human readable string. Then I open connection to the MSCAN, shoot the string to two addresses, x290 for the first 5 chars, and x291 for the second 5.
The chip acts as the traffic controller, switching between 500kbps and 125kbps operations depending on what task it is trying to perform (HS vs MS)

Lol!
Well if anyone can provide me the OBD2 pages and Information Display pages from the series 1 wiring diagram I can tell you if it will work. After talking with the creator of the GB we came to the decision that it probably wouldn't, but both ASH and jrx mentioned that they are the same.
The key here is we are leveraging off both the HS and MS cans
edit: Next step while I wait for the bluetooth chip to come in is to make the left and right clicks of the joystick cycle through different functions. Right now RIGHT goes to text mode, LEFT goes to clock mode. Clicking the direction twice puts it back to ECU mode. I will probably have it cycle through different modes probably [ecu, text, mil codes, clock]. I will have to investigate what else we can do.

Actually the information displays are different between S1 & S2. See the posts here:

They are wired differently & ASH confirmed different part numbers.

Gotcha, thanks for that, yea I feel like I read somewhere that the info display used some spi controls and whatnot as opposed to canbus addressing on the older gen. I actually think the canbus information displays became available with the 2005ish mazda3's.

99% sure these are some DTCs in a series I ROM. I believe Cobb just FF's them out.
Does anyone know what CPU the SII ECU uses? If it is still a SH7055 with some new code, I can probably help some. None of this is my forté really, but I've reversed most of the table locations out of my AP. To the degree to which they are similar, that info may be useful to you, at least after I transfer it off of scraps of paper covering my desk.
However if you want to flash roms, then you need a J2534 device.

No, found it online. The AP dumps are encrypted with AES, and though they thoughtfully include the keys in all of their software, I didn't realize that until I started work on that rom.
I really need to acquire a cable from tactrix.com so I can dump/flash without the AP, but my hobby budget is at 0.
