I still need to implement these two tables. Will try today.

Ok, I've implemented into ZA1JA01C, download this definition:

https://raw.github.com/TD-D/SubaruDe...R_ZA1JA01C.xml

Td-d 03-10-2014 10:01 AM

They are in the Mass Airflow / Engine Load section.

@troek - what's your CAL id?

Nevermind, I've added to ZA1JA01A, here:

https://raw.github.com/TD-D/SubaruDe...R_ZA1JA01A.xml

Td-d 03-10-2014 11:48 AM

Ok, I've added to all roms on my Github repository:

https://github.com/TD-D/SubaruDefs/t.../RomRaider/ecu

Remember, if you are downloading from here, make sure that you click on "raw" to get the actual XML (otherwise you will download an html page!)

EDIT: I cant seem to find that table in RomRaider.

I've made all rows the same using the lower ones as a template.

so you have all rows reading 8, 7, 7, 5, 5, etc?

Not at this stage - but if there's anything specific you want, let me know.

troek 03-11-2014 04:10 AM

yes this definitely made a difference, now im not afraid to start my car at 5 am lol. thanks. im runing all tables the same in the maf correction after start, 1400 rpm target idle, and reduced to -8 timing in the post start table. its a pretty significant change.

Any idea on the table logic for the post start maf correction? As in what the table actually does? Initially I thought it was just a post start reference or target value for maf g/s.

If this is a reference (initial estimated maf reading used for fueling right after it catches) then it would not make sense for this table to affect the cold start beyond the first second or so of the cold start.

If, on the other hand, it is a maf target table used during cold start then it makes perfect sense and I would assume the ecu adjusts throttle plate angle to get the desired air flow. On 21*C cold start i see 18 - 19 g/s during the high idle cold start.

Td-d 03-11-2014 08:28 AM

I'll dig into the logic but I don't believe it's a reference - that was already available as the post start airflow reference and the load reference tables.

Td-d 03-11-2014 12:02 PM

It's definitely an adder to MAF.

My car never idles over 900 rpm even if under 10F overnight. I'm hopefully about to buy BRZ edit, perhaps I could send my bin for those more familiar with these cars to compar (mine is a fall 2012 dealer flash.)

You won't have these tables in BRZedit (yet, I'm sure they'll get copied soon enough ;) )

Yup, I've implemented across all roms. Yours is probably ZA1JA00C.

troek 03-12-2014 08:02 AM

are you invovled with romraider or are you just some random helpful dude?

Nope the dealer won't flash that on 2012 built cars, mine's ZA1JA00C.

Chuckle... when you say involved, not with the development no (there are others that carry that torch), but I guess you could say I've mostly taken over the role of creating definitions for the past two years or so. I've also been actively involved in digging out features that were available on other platforms (like COBB's AP) and implementing them for open source.

? As I said, ZA1JA00C. In any case - the tables are available for this rom, yes.

Sorry I've got to get bifocals, you know quite a bit about these cars.


What is your opinion on the stability/risk with ECUflash as is stands today?

No worries, 2 / 3 more years, and I'm at that age as well sadly!

There's quite a number of people who've used it successfully on here - also, Mikey contacted me last week, they are about to issue a new release, which I'm hoping has implemented the proprietary Ecuflash kernel. This will definitely make flashing easier, and faster.

It's not for everybody I guess, but I like the freedom that a completely open platform offers.

Don't count on it. He has not updated defs in a very long time. In fact I would not ever expect another update from epifan.

The dealer can only flash factory roms so yours is likely already available for download etc. I'm starting to think they flashed the wrong image in your car. I can't fathom how the cold start cold be so broken without throwing any codes.

Thanks man, so now the question becomes is it used to create a target load / airflow value or is it just for fueling. I can play around with it a bit this weekend. Should be easy enough to figure out now.

Hey troek do you mind posting a screenshot of the tables you changed? That would be awesome.

-someone else who care about their neighbors :lol:

troek 03-24-2014 03:31 PM

im out the door to work right now, but ill take some shots when i get home tonight. if you wanter lower idle speed adjust idle tables A and B in the 1700 values to 1400 for example. im trying my post start idle ignition timing at 0 right now, and it seems to not have any benefit, ill probalby go back to -8 next time i flash, just to be on the safe side as we cant yet adjust the retarded injection.

Hey there

Just getting to this now. Any chance you could post a LITTLE higher res photo? Hard to read the values :) Thanks man

nvm. Think I got it

-8.05 for all inigntion timing post start

Copy rows values in rows 3-8 to rows 1-2 for maf correction after start (in gear and neutral) :cheers:

troek 03-27-2014 11:45 PM

sorry, i didnt realize it was so blurry. its actually 0, but -8 dosnt sound any louder, so i think its a safer bet since its thats much closer to factory. and correct, for the maf just copy the values from the lower rows.

FRS_FIEND 03-28-2014 01:05 AM

people are so technical :] lol (i say that in a great way). Just tap the accelerator right after you start and it will idle normal and it wont be doing high revs and let it sit till it gets to idle operating temp. TA-DA! LMAO of course i have no idea if thats bad but it shouldnt be as long as you wait a lil longer for the warming up. no i dont do this everyday its just something i stumbled upon. One day before work (tired as hell) i when to start my frs in the garage and reversed her outside as if i was going to work ( i was still in my boxers, yeah that tired lol) then realized i still needed to get dressed for work so i stopped on my driveway and let it warm up and it was normal idle not the high revving cold start. lol

grrrr... romraider is telling me those xml files are invalid for the ECU def for A00C....


LMAO... ooooops... nevermind... I clearly need more coffee NOW!

Got the file working in XML format however when I open a table I get this error...


Edit: OK... some how... I rebooted my PC and now it works no issues.... wtf!

Don't worry about that, fix the checksum with Ecuflash, or OFT, and it's fine.

I know OFT will fix the file but when it error's its not editable... What am I not understanding?

Td-d 03-29-2014 04:05 PM

What that message means is that editing of the table "Checksum 2" is disabled, the other tables will all be editable.

Yup, i'm an idiot. Thx

EDIT:
Just reflashed the car after adjusting the above maps. Works GREAT! Its 33*F here, on a cold start the car fired right up with ~1 sec of loudness then calmed right down. Still idling at ~1400 but very minimal noise. (full exhaust)

Thanks!

cruizin01 03-31-2014 10:22 AM

Got a cel with a p050b code this morning. Fail.

Guess this needs a little work.
