ECUFlash - Getting close!

have micro sd in tactrix
created logcfg.txt file and added triggers
unfortunately no logged data

Would be happy to test ram addresses and logging if I get it going ect

Here's what I've been using.

The only thing I'm really missing is the AVCS info on intake and exhaust and the defogger or something to use as a trigger, which I'm hoping will be found soon

Right now I have no trigger so it starts logging as soon as you plug it in.

Sure - it's Reverse Polish Notation, so add:

scalingrpn = x,100,*

In other words:

;E_AF_Learning_1_A_StoredExt_E44 FFF815C4
paramname = AF_Learning_1_A
paramid = 0xFFF815C4
isfloat = 1
scalingrpn = x,100,*

to the bottom of each range. Looking at your data, I do believe I've found the A-D stored AF learning ranges, should be useful given that a tool like learning view is not yet available for the BRZ's. Would be good to verify with a longer drive, to see the learning change. The 'current range' address does have correlation with the AF ranges by the looks of it, but I'm just not sure - a longer drive will help.

I've updated my logcfg (as well as the one linked above) with scaling. I think I'm allergic to RPN or something, it makes my head hurt and I can't figure out why.

I'll log a drive this afternoon and post it up for you.

Ok here's two longer datalogs:

As you can see from the coolant temperature the car wasn't quite warm yet in this one.

This is ~20 minutes or so later:

I hope this helps!

Thanks. Just tried it and now get log output to SD card. I must have stuffed up triggers.

Bad news is that most of the RAM addresses are not correct for my G series ROM.

Do you know where I could find these ??

Might have to ask @ztan as he is in Australia

Thanks again

At this point in the project do you guys need any assistance testing at the user level? I'd love to help but I don't know much about disassembly. However I do have access to logging some parameters.

This is the A01G logcfg that I am currently using.

Notes:

Port_IPW is the value before latency gets added.
Direct_IPW_0 is the parameter that gets passed to GDI Flow rate table for the y-axis.
I've got params for AFCorr3 and AFLearn3 - I think they're ok.
I've commented a number of params that I've tried, some work some don't.
This logfile will get you 20Hz logging, 1-2 extra params will drop you into the 13Hz speed bracket.

Would be interested to see your IAT values and IAT vs trim logs. My car takes on a lot of heat and holds it, messes up my trims by 2-4% depending on intake temps.

Hmm... the range definitely seems to be correct, but I'm not convinced about the stored values now - since they have not changed at all - I would expect some changes in the learning at least over a 20 minutes drive...

I can reset the ecu and log again if you want to see if that makes the trims more exciting...

Good point - that would very clearly show if these are the stored values or not...

Did some logging with my elm327 a while ago on IAT vs ambient air temp and in traffic mine can get 20 C or more above ambient and hold it for quite some time. Suppose having headers directly below intake is not good

I have actually covered my Intake and air box in heat reflective aluminum tape. This has reduced the difference between ambient and IAT by 50% ie I now rarely see over 9 C difference in traffic in summer and it recovers to 2 to 5 degrees quite quickly. Also removed the plastic piece on underside of bonnet on drivers side (couple of plastic clips) to let heat out at low speeds.

Will send the before/after data logs when I find them.

Thanks again.

What is involved in updating a 2012 manual bas scion to the latest factory rom? Been too long (90's) to understand why I need to find the exact new factory rom.
