Who else love's their Tuning Alliance tune ?

[Tuning Alliance]

That's in all the OS maps as well. The AF #1 is trivial to change, the AF #3 takes a little more work to get to:

You're correct about the idle airflow throttle target not being commonly defined, however.

 

What about disabling CEL's, I noticed in a 03 wrx i was doing the other day, i was still getting pending codes. They won't throw the actual cel, but is there a way to shut them off in OS?

That depends on the map, unfortunately. Generally if you can find a similar ROM with them defined, I'd imagine it's not much work to find the CEL tables and addresses, but that involves being comfortable with hex editing (the major downside to OS tuning, for sure).

 

For example, the "latest" ECUFlash ROM for my '07 spec.B does not have the CEL tables defined, but someone on the forums got them added to the definition. I imagine all they had to do was search for the CEL block in hex from a similar LGT ROM and find the address of where those tables start, though I didn't do it myself.

Did you mean like this, or does disabling a DTC this way not necessarily disable pending codes?

I'm not really in love with that method of limiting the a/f learning, as you loose a break point the in the table, but I suppose it'll work.

No, you don't lose a break point in the table. It's exactly the same as the AP from what I can tell. You leave the first three cells the same (5, 10, 40 g/s on a stock rom) and then modify the fourth (80 on my stock ROM). The fourth is the limit.

 

Edit: ah, that's the wrong thread with essentially all the information you need. There's a thread somewhere on this site where someone (i want to say it was covertrussian) changed the limit value (instead of the D cell value) and it seemed to work as intended.

Mike, in case you're interested on trying this with your OS tunes here's how you "unlock" the "A/F Learning #1 Modify Airflow Limit (Min/Max)" tables:

 

1. Open up your OS ROM and edit the map for the A/F Learning #1 Airflow Ranges.

2. Subtract 4 from the address listed (use Windows' built-in calculator in "Programmer" mode, or just use an online hexadecimal calculator if you're not familiar with hexadecimal arithmetic), increase the number of elements to 5, and then add in lines in the description for the map for "Min Learning A" and "Max Learning D."

 

That's it! Here's a before/after screenshot of what it looks like for my particular ROM ('07 spec.B A2UI000L). In my case, the A/F #1 Learning Max A/Min B range is located at address 0xC8AE0. The Min A is located 2 bytes before the Max A/Min B value (2 bytes works out to an offset of 4), so subtract 4 from the address to begin the table there (in my case, 0xC8AE0 - 0x4 = 0xC8ADC). The Max D value is located 2 bytes after the Max C/Min D value, so you can just extend the table to look at 5 elements instead of 3, and they'll all appear in one table.

 

I imagine this should be an identical procedure for all 32-bit Subaru ECUs that use the same closed-loop learning logic. All it is in memory is 10 consecutive bytes (2-bytes per entry in the table), which should be pretty easy to find assuming the ECUs stock map uses the same ranges (1.6g/s min, 5.6, 10.0, 40.0, 80.0 max) by just searching for the bytes "3F CC CC CC 40 B3 33 33 41 20 00 00 42 20 00 00 42 A0 00 00" in a hex editor.

I've done the same on my 3.6R and it works as intended.

 

I also disabled all AF Learn/Correct #3 and #4 (H6, so both Bank 1 and Bank 2 tables apply) fueling contributions because my O2 sensors are no longer physically located behind the cats (making any/all fueling contributions to CL suggested by them useless).

That's actually how Subaru restricts learning after a certain point, they use a table called "AF#1 Learning Max Threshold" and for 05's it's set to 80g/s.

 

Funny thing is, since stock scale D column set to 40.00+ even though the ECU stops at learning past 80g/s it still will apply everything learned between 10-80g/s and apply it to open loop, kind of dumb logic honestly.

 

By setting the AF Learning lower, your not really loosing a break point or anything. You just need to make sure you adjust the Learning scales to go up to the "AF#1 Learning Max Threshold" value. I'm not sure how Cobb is different about this, they all use the same ECU code so as long as tables are defined right should be no different .

 

More details on this can be found in the link I mention below.

Here's the post that you are talking about

Yes, I understand (as solidxsnake already pointed it out), but like I said it is not present in all the standard definition files. Obviously exists in the ECU.

An update on my Tuning Alliance Stage 2 Tune:

 

From the mouth of my better half, "This is how this car should have came from the factory.".

 

I installed invidia up\down pipes, and a grimspeed crosspipe, I was afraid the crosspipe would get too hot around the oil filter so I engineered a heat shield from the OEM one.

 

Took me the better part of a day working by myself, mostly because of little things like trimming the turbo heatshield, making the crosspipe shield, and making sure I got every bolt torqued correctly. (I'm a bit OCD and paranoid when it comes to my cars).

 

I couldn't help but laugh as my father watched me hook up the test connectors and proceed to flash the ecu, as he asked "have you done this before?"

 

"Welp, I've read but never written".

(He is from the muscle car generation, so anything past bolt ons and engine mods are foreign to him, pun intended)

 

So the flash went flawless, I was more nervous for those two minutes than the entire days work. Unplugged test connectors, said a short prayer,and turned the key.

 

I could hear the difference immediately.

 

Guys, just let me say, that was the best $200 I have ever spent on a car.

 

I turned my logger on, all looked well, so I proceeded to make my 2hour voyage home, keeping the revs low, as hard as that was.

 

 

Flawless, that is the word.

I've driven this same 2hr drive 100 times, and could point out every hill\bump\curve where the car would stumble like it wasn't programmed right.

 

Not now.

 

i can FINALLY leave this car in D and forget about what rpm range I'm in, I can forget about being afraid my car will bog at the wrong time.

 

If you buy an 05\06 LGT, take my advice, buy the down\uppipes, get Mike to send you a tune, and skip the hassle of being upset at the factory tune.

 

I took a short drive earlier, can hear the most beautiful spooling sound by 2000rpm.

 

I fkkn love my TA tune, and you will too.

 

 

I think this is the post i needed to read

 

being a noob and having the infamous fourth generation stumble problem, I have a feeling that wiping the factory tune is the only option. and reading these fantastic reviews about TA made me feel much more comfortable.

 

once I get an after market up-pipe and down-pipe installed, I will be contacting TA again.

[Max Capacity]

You may want to get your up/dp from TA, they can sell you what you need. Build a relationship with them. It has great payback. Great customer service.

 

You may be able to do the install...soon too...??? How great will that be for us who are local...

RomRaider definitions are falling behind a bit (due to the pain to update them), ECUFlash definitions actually have all of these. Next time you need to tune an opensource car use the latest version of ECUFlash and you should be good to go (ECUFlash def's on RomRaider.com are way out of date too ).

[Max Capacity]

Been a while since I've updated on my wagon. The vf52 has 92,000 miles. I had the dp and up off the week, checked the turbo, zero shaft play. The car was down for a week and a half or so for various reasons, exhaust leak at up pipe, PS pump leak, brake line leak (Subaru replaced all the brake lines and left rear caliper, at no charge), had a bad wheel speed sensor.

 

While the wagon was down I drove my Spec B. It's also tuned by Mike, but the difference the vf52 makes in the wagon is amazing. It's so responsive and keeps making HP up top where the vf46 falls off.

 

Last Saturday while the wheel speed sensor was being a PITA. I put the wheel back on a said let someone else fix it. While at diner that night my GF ask me, if I was fed up with the car? I asked, do you think I's ready to sell it ? I said no way, life is great when I put my foot into the throttle. There's nothing out there with this much bang for the buck.

 

Thanks again to Mike for giving me such a fun car to drive.

btw, does your car see redline (or close to it) at least once a day?

[Max Capacity]

I won't say once a day. But yea, I have no problem going there when I "feel the need, the need for speed".

 

On the back roads out through the farm fields of a town called Ellington, there are some fun curves and great places to run the car through the gears coming off a stop sign.

 

 

My DD to work is 28 miles in CC at about 62mph...going home is different...Soon the car will be going back to VT each weekend as well as the DD to work, ski season is almost here.
