Wjile ztan has done the bulk of ghe work on the manual A01G rom which is what i believe @Yobiwan is using but simply calid changed to load into his oft, a calid change to a compatable rom is easy.


Unfortunatly from memory you were auto rom and manual and auto not compatable.


So you would need to port across ztans speed density subroutines over to the auto equlivant rom an A01I as this will be similar structure to A01G.


You would​ need to identify the same areas of the auto rom to patch in the speed density code. Then test to do this ztan used IDA a reverse engineering tool and then HEW to test code. Even then ztan bricked at least one ecu.

Could you upload the def for the SD hybrid. I tried to patch my def but it has no rpm or kpa values.

Is it possible to flash A01G to a C series. If not, does anybody have the hybrid speed density files for the C series ecu.

Yes, G is MT and so is C.

Yes you can flash the A01G rom to any 86\brz\frs manual car from 2012-2016 ie pre facelift.


It will not work with facelift 2017 plus cars car wont start

I used ecuflash to flash A01G hybrid. Said yes to correct checksum in ecuflash then flashed. This also helped idle after a rev. Thank you guys for your time and help.

Hey guys. I'm using the ZA1JB01C SD mod but the definitions are gone. I was able to find some screen caps of the work I was doing to recover the 'Speed Density MAF' (d15a0)and 'Speed density Blend' (d14a0)tables on ECUFlash, but I'm missing the address for 'Speed Density Mode' table. I'm also unsure of the scalar that's supposed to be used here. Can anyone help me out? @ztan ?

*Edit* NM I was lucky enough to find the address for Speed Density Mode in an old email. (d1482) The table is supposed to be a switch but the speed density mode scalar works fine.

didztan specificly mod your B01C rom or its it jst a cald altered A01G if so the A01G SD def should work

I can't recall what exactly he did, but I can't get the A01G ROMs to start on mine; SD or non-SD so I gave up. *side note* A01C and B01C non-SD were fine but I couldn't get them to stop targeting 13.78 AFR on Idle and cruise even after zeroing out the AF3 tables. I ended up back with the B01C SD ZTAN made me. I'm guessing its running a rear O2 sim?

Anyway, the addresses for SD on the A01G don't work on B01C that was the first thing I tried, so maybe he didn't? I would love to look at the rest of the corrections made on Romraider since there are more tables defined there, but my B01C SD ROM won't open on it.
