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

[Td-d]

There's a newer version of the beta on the tactrix website, by the way:

I finally got the B01C rom to log! The defogger parameter isn't working so I had to use the RPM trigger, and it worked. I didn't put all the new parameters, but the ones I did use some of them seem right but some of them don't. Here is a log file and my logcfg.

I see the defogger isvisible = 0 is still in your logcfg file - did you try and see if the defogger works with this line removed?

Yes, I tried that. I eventually just copied a new logcfg and started over, that's why it's still there

Looks like my csv didn't upload last night, here is the datazap.me chart. Looking over it this morning the only parameters that really don't look right are fuel_system_status and RPM. BUT the fuel_system_status_2 and the RPM2 look right. IAM is showing all 1's and IAT and IAT_2 both look right but one has to be ambient air(IAT), and other is actual intake temp(IAT_2) I think.

I was messing around with the OP2 tonight and found that there are some combinations that won't allow the logger to work. Throttle position in conjunction with one of the other params (can't find it now) will not allow the log start to trigger.

There are also a few that have combinations that force the logger to record when the car is on and off. AF_Correction1 and AF_Learning1 in combo make the logger record as long as the ignition is on.

When using both MAF and MAF2 params the defogger switch start doesnt work; as well as when using both MAF Voltage and MAF params.

This is a short list of the ones I found that cause the logger to run with the ignition on.

; similar to STFT / 100
paramname = STFT_AF_Correction1
paramid = 0xFFF8A5EC
isfloat = 1

; same as LTFT / 100
paramname = LTFT_AF_Learning1
paramid = 0xFFF8A774
isfloat = 1

paramname = STFT
paramid = 0xFFF8DB74
isfloat = 1

paramname = LTFT
paramid = 0xFFF8DB78
isfloat = 1

paramname = Direct_Injector_PW
paramid = 0xFFF887E8
isfloat = 1

paramname = Direct_Injector_PW_Ram
paramid = 0xFFF887F0
isfloat = 1



*EDIT* I just realized that in previous logs I had these closer to the end and they worked just fine. When I put these to the front of the list it causes an issue.

[ML]

So did you actually get the defogger to show in the csv files at all?

[D-VO]

Yep!

[ML]

can you upload your logcfg.txt please! This is on B01C right?

[D-VO]

Correct. Here ya go!

Please feel free to let me know if you can find any other params that are loggable. I have a few missing from here.

Just in case anyone was interested; I found the working addresses for both the IAT and Coolant temps for the ZA1JB01C, from the list provided. I also wrote a little scaling RPN to convert the both of them it to Fahrenheit.

paramname = IAT
paramid = 0xFFF8DBA4
isfloat = 1
scalingrpn = x,1.8,*,32,+

paramname = Coolant_Temp_F
paramid = 0xFFF8DB88
isfloat = 1
scalingrpn = x,1.8,*,32,+

The only problem is we need ltft/stft to work together.

Thought it might be helpful if people posted up their STOCK factory ROMs with latest revision's (CAL-ID's) so other with older ROM's could update

If you post them up I will add them to original post

Have A01G and B01C already.

Thanks

Steve, I've got all the roms - want me to Dropbox them to you?
