The dealer would never notice. There is no flash counter on the ecu and as far as I know the dealership does not have the ability to look at tables. The ecu version will read correctly as well.
That question was just asked on iwsti and a few chimed in saying that the dealer can tell the ecu was flashed even if it was flashed back with the stock image before bringing it in... some type of counter or something. I've got no first hand knowledge of this, just relaying info. I know my GM ecu used to track mileage, vin and version.
The SSM3 can compare checksums.... but there is no flash counter. That being said if you pull a backup map and reflash that back onto the ecu it is identical to the day you backed it up.
So where is the download to start tuning? I have a cable from my Evo, emailed Tactrix and they said it will work w/ my 04 Sti but I can't find the datalogging software, and tuning stuff. Any help?
To pull maps off and flash them back on I use ECUFlash and you can DL that at www.openecu.org . I used http://www.enginuity.org for map modifications.
Hrm, I'm interested in flashing my 06 5MT stage 1 (only "mods" are a drop in and silencer delete). Wall of tv's, you have a good map? Was planning on purchasing the AP, but if I can save the $$'s...
The 2006's have timing issues that haven't been worked out yet. You have to be kinda conservative with boost until these problems are sorted out. Those things are still torque monsters compared to the 2.0's even at 15psi, tho. http://www.mnsubaru.com/forums/showthread.php?t=13964#post257500
Even going to stage 1 is kind of tricky in the '06, but I'm really close to having my map finalized. My map is targeted for 13.5psi and doesn't pull any timing now that I got my KC table figured out to compensate for the "weird '06 timing weirdness." So yeah, I could help you out if you would like.
So... this would work on the 07 as well, correct? I too, am looking for a Stage 1. (drop-in & Silencer delete)
I've already put copies of his ROM over on Enginuity, OpenECU, and Open Source ECU Roms.... It's out there
Since I'd like to purchase the cable myself, I'm thinking that I'll just grab a conservative stage 1 map, and flash it myself. After a bit of research, it seems like something I could get the hang of pretty quick. I was thinking of using evasive's stage 1 map from the XPT tuning forums, but I'm open to other ideas...any suggestions?
I wouldn't exactly call ev8siv3's '06 stage 1 map "conservative." I've had to tweak it quite a bit to get it to keep from pulling timing on my car. There are some spots in the low load/rpm areas that have MASSIVE DETONATION due to the high AVCS numbers angles and increased boost and stock timing. I'm not ripping his base maps in anyway, though. He does a great job in providing really good starting points to work from and would recommend them to anyone who is willing to experiment and tinker with them. If you want some help just lemme know.
Fair enough. I'm thinking of just purchasing all the hardware and pulling logs/doing research before I make many changes. Any other suggestions of other base maps that are more situated for 06's here in MN? I'd like to see what I can do on my own, since I'm sure I'd learn better that way. Wish the openecu forums would come back up..
Go and look around on the Enginuity forums. It is probably the best in terms tuning disussion. And yeah, the best way to learn is to do it yourself. It isn't nearly as hard as some of the "professionals" would want you to believe.
Wall, if you would be so kind... Here's a link to my ROM that Shane pulled off my ECU. http://www.enginuity.org/about909.html
i just found out that enginuity has figured out launch control and live tuning. it should be released in february. here is a link that jared(qoncept) sent me
Yup, they are on the fasttrack to getting realtime tuning, launch control AND PER-GEAR WASTEGATE COMPENSATION (w00t x infinity) a reality. It looks like once you point the ecu to read from the RAM areas, you can re-write the code to make it do some pretty cool stuff, provided you have the memory space and the right tables to butcher up, hehehe. w_o_t_boy & bikerwriter are both beta-testers for the realtime tuning bits. Also, we are now 1 step closer to eliminating that retarded timing issue on the '06 WRX. I just tested out a beta definition file and adjusted the new table -- and had GREAT success with it. Unfortunately, this doesn't remove the 11* minimum timing threshold below ~3800rpms, but it definitely gets rid of the jackass "sawtooth" timing that was nearly uncontrollable. I'm very hapy about this!
Ok, here's the wacky timing I was just talking about that rears it's ugly head -- stock or modified, it wouldn't follow out the timing that was set in the ecu.
Here's after I fixed the problem while doing some beta testing with that new definition file. I also smoothed out a few spots in the timing curve. It's pretty obvious that the ecu isn't doing that jackass "sawtooth" timing it was before. yay. Now all we need to find is the 11* minimum threshold and I'll be ready to throw on the stinkpipes and shoot for 300wtq!
And finally, here's a little road dyno readout I just took a few minutes ago -- stage1 vs stock with an axelback exhaust. Please disregard the "tail" above ~6000 rpm as the graph is a polynomial curve that fits the data set and does weird stuff after the data ends (in this case just above 6k rpm). I like this stuff, lol.
Yeah!! I posted in that same thread (Bullwinkle1983 on the enginuity forums). Those guys are money. I haven't had a change to test out the new def file, since I'm in FL for the break. Will try when I get back. Did you just follow instructions and drop the new table to 0's? I've been tinkering with the OTS '06 stage 1's from the osecu site. Any chance you want to PM or post your (timing) edited base map, so I can compare?
Yup, I did what Airboy did and zeroed out the table. If you are wondering about the timing tables, take a look at my above graphs. It should give you an idea of what I had to do to deal with the (11* + KC) minimum timing issue -- flatten out the base and run a non-static KC table. It works really well; I'm suprised that ev8siv3 (osecu guy) hasn't figured this out yet.
Well unfortunately for you the new beta definitions are for 2006 WRXs right now, so you'll still get that chainsaw timing below 3800 rpm.
One more question. Did you take evasive's basemap and edit the timing in the WOT load/rpm areas (to match the 11* min), and then smooth from there (adding KC as you go along)? Or did you recreate the tables on your own?
Not sure if I've posted this before or not, but if anyone wants to play with an 07 stock ROM, here she is! Straight out of my car with 31 miles on it. http://forums.openecu.org/download.php?id=933 direct download. http://forums.openecu.org/viewtopic.php?t=1324 for the topic.
I did a little of both. He has some good basemaps to START with -- I like them simply because I don't have to rescale everything (it's a pita to do).
everyone has to remember that you really need to have the knowledge to do this(like wall of tvs). you cant just take those basemaps off enginuity, openecu, osecuroms, etc and just starting using them without have a knowledgable person change it to fit YOUR car.
^^^ exactly The ROMS that are posted up on osecuroms.com are base maps that provide a very good starting point to work from. Don't expect them to work or be safe right off of the bat.
lmao! I just realized that I've made 40 revisions to my current map (and flashed/tested all of them) on my new car. It only has 4000 miles on it....... :lol:
that he is. worked on my ride for a while yesterday and again tonight. i should have some graphs and what not in the next few days.
I'm going to run my old TBE this coming spring. Right now I just have a Prodrive muffler on the car and am running a "stage1-esque" tune on it.
I'm surprised I never came across this before. I've been looking at the AP, but all I really want is just a simple stage 1 for my 05, and $450+ is just a bit too much to swallow. Especially since the car will be going away in 6-12 months. I haven't done a ton of research yet, but it looks to me that the 05 ev8siv3 stage 1 would be the right way to go? And since it's an 05, I shouldn't see any of the issues that are cropping up with the 06+? Is there anything I need to look at for at all on my 05, or just flash and go like the AP stage 1? I'm not looking for much, just a little better drivability at low speeds, which seems to be the most noticable feature with the stage 1 stuff.
Yeah, there are some weird things happening with the 2006 WRX regarding timing that doesn't happen with any other car. I have yet to test out ev8siv3's stage1 map for the 02-05 WRX. If it's anything like the other maps of his I've used, it will definitely need some (or a lot) tweaking.
