Still having trouble with the definition file for this thing, its the old logic but doesnt match any of the old definition files. Attempted reverse engineering the rom using IDA but its a little beyond my current understanding. Anyone know an easier way to identify the tables if they should be similar to a previous rom?

I'll have a go with ScoobyRom it looks promising and see how far I can get. Hopefully post findings and guidance back to the forum incase anyone else fancies giving it a go on any new roms. Cheers.

As the auto and even the manuals in europe did not get the updates like the australian and usa red manifold . You may be in luck and you may be able to flash in the older A01I rom to your car which is definied and has log addresses.

Now this involves some risk.
I did this to a K00P manual here flashed an A01G, now the car did not start , but recovery was to reflash original K00P and resync security. Its jist looping a couple of pins on obd port for 30 min.
All good car recovered and all ok.

Now as your car is old rom logic its possible the older rom will work in your car.
And if not you should be able to recover like i did.

You can make up a flash only definition, see first post in this thread for you K01I rom.

Do that and confirm you can reflash your stock rom.

Then try flashing A01I older rom

If car starts runs, log and check all ok, happy days you can now tune

Car wont start reflash original K01I
And then most likely ecu security resync proceedure
Full info here

You wont need to worry about vin or other stuff just reflash K01I

Then loop pins and wait 30 mins

7. Turn OFF ignition
8. Loop pins 4 and 13 on OBD port in car (this puts control units in comms mode)
9. Turn ignition to full ON position with working key or for keyless fob in car and two pushes of start button (in park or not pressing clutch) DO NOT TRY TO START car, DO NOT remove FOB from car during the 30 minute period.

To be really safe here make sure everything electrical is off in car radio, fans lights ect have the drivers window down and doors closed. Reach in through window to operate ignition at start and end of 30 minute period. Because when you open door window does the jump/up/down ie electrical load/spikes .

10. Wait at least 30 minutes (the CEL light should flash if pins looped successfully)
11. turn OFF ignition (again reaching through window not opening door)
12. Remove loop on OBD port pins 4 to 13
13. Start car let it run for more than 5 seconds.
14. Enjoy your car.


Now i cannot offer you a 100% guaranee, however i did this on a 2017 manaual car and recovered. So sgould be same for 2017 auto

Fantastic info steve, I have some friends who are big into mapping and ecu recovery so I will have this with me when we attempt to do mine.

Wow! I had the day off today to look into this but you beat me to it. On with creating a definition file for me


How do you 'thank' a post on here?

I think you need 10 posts or something before thank button shows up

The reason for A01I is it will work in all 2012-2016 auto cars that came with I roms

Same with manuals A01G will work in all 2012-2016 manual

This is confirmed

All ecu even 2017 is same processor and appears to be same hardwsre worldwide

Their are usa guys running G roms in cars that came with C roms originally

[Wayno]

I'd prefer this approach to try A01 and make the K00D/G/I redundant, but perhaps there are quite a few more hardware changes in MY17 than happened in MY15 that the K00x roms might need to be mapped anyway to pull out things like the updated transient ignition retard injector compensations, not to mention all the unmapped stuff, etc. Having said that, most of those changes will appear and could be pulled out of K00G anyway.

The EU MY17 ROMs are more similar to the MY15 G series, although there are still differences. Perhaps that definition is a better starting point.

[Wayno]

Better starting point is the K00G def, as some tables will have identical locations.

Cleaned up that K00G def that was uploaded, added the missing tables.

Looks like EU MY17 got the 4.3 FD.

Around 120 tables done so far, in around 6-8 hours.

No, still the 4.1 I'm afraid.

Wayno sent me the MY17 EU AT stage 1 rom and definition last night, excited to get it loaded and start logging.
Legend!

It has been changed to a 4.3. Guy in our group (Belgium) had a 2016 BRZ after 2 or 3 months the car was totaled by an old lady and he bought a 2017 BRZ, he confirmed the FD change, also the change in suspension setup.

[steve99]

Added ZA1JK00S 2017 Auto Australian rom to first post as supplied by wayno.


note the K00S and the K01I auto roms are interchangeable

Interesting, the MY17 BRZ spec change info state otherwise.
