Tactrix EcuFlash Info for BRZ 86 FRS Rom flash update and logging

[SteveGT86]

Tactrix emailed and support request created on their support manager. Fingers crossed for a reply since my previous query was acknowledged by the software but no followup. I know they're small so maybe on holiday etc.

Looking forward to checking IAM and MAF scaling once the logger works - will use your helpful links !!!!

At least I'm not the only one. I've begun to doubt me.

Please contact the Tactrix support guys at www.tactrix.com

If both of you guys contact tactrix it should get sorted pretty quick, they are usually very good considering their is only two guys in the company ;-)

Email sent. I'll keep you up to date if any news pop up.
Thank you anyway, Steve.

Quick update:
the Tactrix guys have isolated an issue in the current firmware and are working on a fix.

I am trying to use ecu flash to remove a brzedit tune on my ECU, so i can flash ecutek. I am using ZA1JF40C bin file, and have all the definition XML and 32bitbase files in the right place, but i still get an unknown definition error when opening the rom.

Any ideas?

BrzEdit like Ecutek locks the ecu by changing the seed keys so other tuning platforms cannot read or write to ecu.

ecutek cannot read\write to brz edit and vice versa.

Both can be unlocked by using the current tune platform to write back a stock rom to ecu.

Ie use brzedit to write back a stock rom to car to unlock it.

you need to find a brzedit tuner to do this or buy a copy of brzedit to do it yourself, its about $100 for a single licience version and uses tactrix to write, talk to the brzedit guys for exact proceedure that will need to provide you with a stock brzedit format rom to write to ecu as their roms are encrypted you cannot use the standard roms

I understand that. But what you are saying is I can't flash one of these roms without brzedit? My new tuner said brzedit needs to be 100% gone to flash ecutek. The roms listed won't help me?

I have a tactrix, and my brzedit tuner is quite a ways away, and right now I can't get the car to him due too turbo installation without a proper tune.

Correct as per previous post brz edit lock the ecu so only brz edit can read or write to ecu.
you need brz edit to unlock the ecu, so you either get your original brz edit tuner to flash back a stock rom with brzedit or you buy a copy of brzedit yourself and flash back axstock rom supplied by brz edit. once you do that the ecu seed keys are returned to standard and other flashing platforms can access ecu.

i think ecutek guys in uk can unscramble it but you might have to send ecu to them.

it sucks but that the way it is.

the standard stock roms and ecuflash are no use to you untill you get rid of the brzedit locks

same deal with ecutek once flashed you locked to ecutek till you flash back a stock rom with ecutek

also your 2013 car wont be F40C rom thats for 2016 cars if your manual 2013 it likely B01C, flashing an incorrect rom will cause you other problems, but will not solve your current problem due locked ecu

[SirSpectre]

Well that really sucks. Also, the ROM that @DeliciousTuning sent me was F40C, Should I contact them and get B10C?

Yes i think you should, if your car is 2013 then its stock rom was likely B01C, so definitely confirm with them that they sent you correct rom as F40C is for MY 2016 cars and may not be compatable with your car if its 2013

Have you received any response from Tactrix yet? My issue is rotting in their bug tracker for over a month at this point of time.

edit: I wonder if they assigned the same issue number as mine to your request.

It automatically updated the firmware without asking and now won't create any log files at all. It was driving me insane. It gives me a logcfg.out, but no CSV's...ARRRGGHHH...

p.s. I mean at the least they should release an older firmware version with a newer date and code so we can at least be up and running again...

Ok I submitted a support request. Personally I'd prefer they just get live logging working...and then not have to worry about the stinking stand alone logging.

Unfortunately not. Firmware upgrade is forward-only.

Maybe it's possible to circumvent the version check with a hex-edited firmware blob? On another thought I don't want to brick my device.

yeah thought that would be the case, luckly mines still running the older version and working

would be nice if they just put out a quick fix though
