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

[Tor]

I read that on the other Subarus they can start/stop logging by pressing the rear defroster.

Are there any tricks to start/stop logging in our cars?

So most effective/reliable way is just to pull the car over and switching it off/on when wanting to start a new log? (That's how I did it so far).

I was under the impression it was no-no to turn OBD2 adapters on/off with ignition on? Couldn't I just unplug it as well (until I get a cable, obviously a switch is easier)?

Connecting all the data pins != switching the power line.

I got a friend that has a '13 manual frs and he has a cai. He wants me to flash a rom so that the cai would work with the maf sensor, how would i accomplish this?

You can't just flash a rom, you have to do some actual tuning if you want to make an intake work. This isn't a tuning thread.

as per what wayno said

you can start here

aftermarket intakes will upset the maf scaling.

alternative is your mate sells his intake ,puts stock one back on with drop in filter, that about as good as most aftermarket intakes with 10 times less hassle

See here for further info and MAF Scaling

Checked the base timing b in the stage 1 oft 93 tune and it just looks odd could one of you just check it out for me ? Its for my buddys car so I dont want to screw anything up on him.

What am I doing wrong? This is now 2. time that the Tactrix doesn't save my log, despite flashing blue.

1) I plugged it in. Drove, stopped and turned off the engine 2 times, to make 3 logs.

2) Took out card, plugged the card into my computer's card reader (Mac). Copied two logs over. 3) Put the card back in the Tactrix. All good....

3) Put card back in Tactrix - repeated 1)

4) Got home, connected Tactrix via USB (without taking the card out, so I can't be that I didn't put the card in properly). Only the 3 previous logs on the card.


Do I have to delete the logs to get Tactrix to log again?

TACTRIX creats a bit of debug info in a file called “logcfg.out" might give you a clue

also remove any trigger lines in code in logcfg.txt thats the sort of weird stuff that happens with triggers

card must be formatted fat32

dont have laptop connected to tactrix while logging it does not work

[Tor]

Thanks Steve nothing connected, format is FAT32. Clue is probably in the triggers (thanks!):

;-------------triggers---------------

conditionrpn = RPM,0,>	
action = start

conditionrpn = RPM,0,==
action = stop

I think I did like this:

1) Switch off ignition.

2) Wait for Tactrix stop flashing (to be sure not to corrupt the log data, don't know if it's necessary? Normally you shouldn't unplug a disc being written to).

3) Start the car directly again.

I guess starting the engine directly again, maybe it's doesn't have time to boot up, and just never register "conditionrpn = RPM,0,>". When it finally boots, the rpm are already at idle speed.

So I should just delete those lines quoted above? If there are no triggers in the logcfg.txt, what decides when it starts to log, "power on"?


Another question, should I remove the SD card when doing ECU flashing? I do that now just to be safe side, but is it necessary?
