RomRaider

Hello everyone,
I've been working on trying to get a manual tune working for my 2005 usdm outback 30r, I reached out to a few lad but also decided to take the project on late one night while staring into the void with chatGPT.
here is a short summery of what we have done so far
I've given it my rom + roms from similar year 2005 2006 legacy and outback models all with EZ30 engine and automatic or manual transmissions from ADM EDM and JDM
GPT had found key areas where the roms were different and similar and marked down 4 sections shared by all manual and auto roms where the code lived in the same address but was different between auto and manual. I continued teaching it as best as I could the wiring differences between auto and manual to it could have a better understanding.
We tried building a rom with the what we learned but quickly found an internal id code miss match that a test write with ecuflash didnt like.
We then pivoted and included USDM legacy GT manual and automatic roms and chatGPT rescanned everything again finding that the structure of ADM EDM and JDM roms matched but was different from USDM roms though all used the same or similar code to identify manual or automatic operation.
our final version of our rom used my original USDM outback 30R rom with manual logic transplanted from a same year usdm legacy GT.
I recognize that I may still be vary ignorant but to me I see no reason this flash shouldn't work if the changes we made to my original rom are the same changes we see between automatic and manual versions of the same vehicle across markets.

ive attached a copy of my rom if anyone wants to see

have you actually flashed and tested this though or is it all theory at this point?

I haven't flashed this one yet, I'm sourcing a second ECU in case I brick mine and I'm also looking for a new cable for my tactrix.
For now this is all theory and I'd like to test flash soon. I'm just looking for extra input for anything I may have missed. I will absolutely be posting the ROM if it works once I get my hands on another ecu.

ok so ive been trying to flash this tune on my car for a few days now and i keep getting J2534 ERR TIMEOUT
ive replaced cables, tried 2 tactrix units
reinstalled ecuflash and drivers over and over with laptop reboots between
test connectors are plugged in an tight
i can read my stock rom, i can use the compare and test write functions i haven't tried reflashing my stock rom
once i open my tuned rom i cannot flash, test write, compare, or even read the stock rom
according to chatGPT it might be due to my definitions being experimental and in the definition file can see its using subarucan flash method

here is a portion of my log

you'll probably have to change the flash method to match what the ECU is expecting, also worth trying to change 1 or 2 values in the stock file and see if you can flash that on successfully.
