Maybe a noob question but will flashing with OFT or ECUtek fix these issues? Is there any way of telling whether you are on the latest stock ROM via OBD2 or OFT?

Tuners generally base modded ROM's on latest ones available. The DI fix will be included.

They stated repeatedly that they could not upgrade me beyond ZA1JA00C. Because (for MY car) there was not a newer ROM version available in the computer.

I explained that the new ROM was compatible, that Toyota updates their cars, and the newer ROMs solved other problems.
They explained that they could not upgrade me to anything beyond A00C because they were not capable of selecting a newer ROM in the computer.

Whoever you talked to sounds like they didnt have a clue what they were doing

other possiblity is that, for some reason, they didn't receive the latest push update from subaru that contained the reflash files.

wearever you took your car and they told you that, I wouldn't go anyware near there again.

There is a TSB for both the FRS and BRZ for the idle stability/idle drop issue.
FRS: TSB: S-SB-0040-13
BRZ: TSB: 11-136-14

Both TSBs will get you flashed with the latest B01 ROM.

Conflicting info. Would like to get some thoughts on this before I bitch to SOA.

Took my very '13 BRZ (very early, delivered ~2 years ago) to get the rpm drop TSB flashed. Came home, hooked up ecuflash and the calibration is ZA1JA00C. No idea if they did anything per TSB, since the rpms were kinda unstable as usual when idling at a couple of traffic lights.

Anybody knows what exactly this TSB does to other tables? Unfortunately I didn't think to pull what was there before doing the TSB.

Anyway, naturally, that ZA1JA00C calibration does nothing to address transient ignition retard tables, which was the only reason I decided to waste an hour to get this TSB. So, is there a way to know if my dealer did anything at all per TSB (the TSB text says that everything should be updated to ZA1JB01C which didn't happen) or they just claimed they did something when in fact they didn't?

Were people with early '13 BRZ able to get newer calibrations?

If the cal-id still reads as A00C then they did not flash the ecu to the latest firmware which is B01C

AFAIK the A01C addressed the transient ignition retard issue that was in earlier firmware 700C. The B01C just appears to be idle dip issues and air-cond idle dip issues.

But everyone likes to be on latest firmware

Heard a few others had similar issues with dealer refusing to update them to latest firmware pretty sure @regal had same issue and he just flashed latest with ecuflash.

By the way tactrix release BRZ ecuflash official version in website still get the defs and bitbases from github as the ones in the release not the latest.

No it didn't. I wouldn't be posting if it did.

Yep correct it was A01C sorry, I am in another country though just trying to help

If you have ecuflash why not just flash B01C, and if your worried flash it back to A00C for dealer visits ?

I would if there's a ZA1JB01C raw file somewhere, or a techstream-compatible file. Couldn't find it so far.

I'll add that I've seen stock cars pull significant timing as well, and cars with aftermarket intakes tend to do so more as bob has already said. A car I did recently was pulling 4+ degrees under load, where most of the time I don't see more that 2 degrees or so on good 93.

[Circuit Motorsports]

I'd like to point out that the updated flash updates (ROM versions) are cumlative, in that the latest release contains all of the previous versions' corrections.

So the ZA1JB01C calibration does in fact contain the new transient ignition retard table values (first implemented in the A01 ROMs), as well as all previous corrections from earlier calibration versions.

Seems like not all dealerships are up to date on their info, and/or calibration files. I don't know how that process works within a dealership, but it would be great for you guys to find a dealership that is on top of these things.

What in fact was there in my post is a typo. I'm on ZA1JA00C still. Fixed the post.
