Exactly 1 year since my last update of this first post.

I have gone through a huge number of different stage 3 roms and a ton of revisions of each one, but for the past half a year I have stayed with one single base that I think has given me the safest most powerful rom I dare to drive. As there are maps on this rom that are not open source I can not share it, but part of the recipe is no avcs at higher rpm, lots of ignition advance, and as much high rpm boost as the poor VF43 can deliver.

So after more than 2 years at stage 3, it is time to move to stage 3+. For me this includes bigger turbo and injectors.

After long research and option weighing I settled on a Kinugawa TD06SL2/60-1 with the upgraded 9 blade STS turbine and billet compressor wheel. Injectors are ID1000, well tested and supposedly the best.

I will continue to give support and feedback on my shared roms.

Happy tuning!

Cheers,
Patrick

As I was helping another mate here I saw that there are a couple of improvements that can be done to the stage 1 rom and I want to share these with the open source community. So please find r3 of the high boost stage 1 rom attached at the end of this post.

The changes are not really that big but do make sense when I look at them with the experience that I have today. I have been tuning (mostly my own car but now also a couple of mates cars) for close to a year and a half now and experience should not be underestimated.

It is also rather straight forward to create a "stage 2" rom from this stage 1 rom, that development is underway in the wrx section right now. If you are looking for a Forester specific stage 2 rom, you should look at the development taking place there.

My own car probably belongs to the worlds most logged, analysed, tested, and flashed FXT's. It also runs quite well but I am already dreaming of a larger turbo (and built bottom end).

2012-07-21, Stockholm, Sweden. Summer time. Temps 20-30 C and a little more humid (but probably considered very dry compared to the rest of the world), and therefore my last roms are "safer" when it comes to ignition timing advance. Still 98 RON and sea level.

The stage 3 rom I am sharing now can be considered safe, I log knock like crazy and this rom has no knock count above idle. It runs really well but I decided to chase some more torque and power now for a while.

See r28 attached both at the end of this post and on page 17. The new rom development starts on page 17 but as it's not tested at all yet I don't dare to share it.

2012-05-02, Stockholm Sweden, 98 RON, sea level, coldish and dryish.

As a thank you to all that share here I did a revision to the stage 1 rom. Test it and see. The only tables that probably will need fixing are the waste gate duty cycles, if you test this rom and don't reach target boost I can help you.

Regarding my present rom, it is on page 14.

I have decided to update this first post with my last revisions of my various stage 3 tunes that I have tested.

The first is an EDM 2007 STI based rom, it is almost entirely my own based on what I think a good EDM based STI tune should be. DBW is gabedudes. I searched everywhere for open source EDM STI tunes but none were found. It is in my opinion a racing feeling rom. The boost is stock STI (peaks at about 1 bar, 14.5 psi, and stays there) and load is therefore quite a bit lower than in the rom below but the mass air flow is about the same on top. Tons of ignition advance though so be careful.

A typical log would peak at about 3.2 g/rev and 285 g/s if I recall correctly, it has been a while since I logged it.

The second is a rom that once had a start with d0nets wrx rom that can be found in that section. This revision only keeps the avcs table from that rom. This last revision has some further and not thoroughly tested revisions but as I saw a little bit of knock at high rpm and high load in todays log (I ran this for 3 days) I decided to try something completely different. This last revision also has Throttlehappys idea of DBW "on the bottom" and gabedudes DBW "on top". I am actually really surprised at the combination and I will continue using and developing it in the future. This rom will peak at close to 1.4 bar (20 psi) and tapers to about 1.1 bar (16 psi) on top. Load is significantly higher with peak of around 3.6 g/rev and I have consistently logged flow of over 290 g/s (with a one time high of 297 g/s but often 295).

And then stage 3 rom 3 (the charm?), back to the 2007 EDM STI influence. Leaner, meaner, boostier and hopefully really powerful. Check page 11 in this thread for start of comments and revisions.

Hi!

2012-01-10, Sweden, 98 RON (should be more or less equal to US 93), sea level, cold and dry.

To skip having to read (although it is not a bad idea to learn from reading) please see my final, although untested, stage 1 map. It peaks at about 1 bar (14.5 psi) and then I more or less let the stock TD04 turbo push as much air as it can which translates to about 0.7 bar (10 psi) on top.

Everything from air filter to exhaust is 100% stock. A lot of the maps are changed from stock and it pulls nicely and strongly, a transformed engine!

The ROM is attached here at the end of this post, it is revision 11.

Then I did what Subaru should have offered us here in Europe: a Forester STI! In this case the end product will be a "Stage 2 STI map", or "Stage 3 FXT map" and includes several hardware mods. That development is on page 7 of this thread at the moment. If you are running a stock FXT you should not try to flash that file although physically it fits.

Please remember that I take no responsibility and log, log, log.

Hi!

Instead of continuing in the USDM thread I decided to start my own thread.

I drive a 2007 FXT EDM 4EAT, a nice car that is so much nicer with just the simple remap of the DBW.

I am located in Sweden, close to sea level and I use 98 RON.

I also want to say that I am so happy about this open source tuning, it makes my life so much more fun!

I am almost done collecting all the parts I need for me planned "STI stage 2" upgrade consisting of a VF43, STI TMIC, Cobb TBE and Walbro 255 pump. I will need quite a bit of help there with a base map that I can use to start the car and safely drive it to the pro tuner that I intend to use for that. Should I try and use an STI base map or try and find a WRX map that may work? Any input is greatly appreciated!

In the meantime I have decided to try and do my own "stage 1" FXT.

In the other USDM thread I have attached my original file just in case anyone is interested and wants to compare an EDM file. I have an A8DK100P.

In this post I have attached the latest version (r5) of my tuned file, it is largely based on gabedudes r30 for a wrx but modfied using a number of sources and my own guesswork.

I am chasing my target boost of 1 bar (14.5 psi) but having a little trouble reaching it, that is why my wg tables look the way they do at the moment, this is r5 for me.

In the Android community I give small donations (not big but enough to buy a beer or a good coffee) to the developers of good roms, do you do that here too? Thank you all that have shared their work!

I have taken several logs, but none yet with this r5. I will try and take a log and post this asap if I reach target boost or close to it.

No knock (touch wood) yet.

Otherwise perhaps someone can guide me on how I can reach my target boost?

Cheers,
Patrick

Use this tool to build a basic config:

Then tweak it from there

test if it will start logging with this file on it, did not try yet.
