RomRaider

Im currently trying to finish my 5 year long project. Took so long because it was my daily. Now that i have my toyota 94 pickup 22re, im ready to finally pull the trigger on making this a fast car.

so far my mod list is:

1000cc DW Sidefeed Injectors
Grimmspeed Top Mount Verticooler
Grimmspeed Catless Uppipe
Invidia High Flow Catted Downpipe
Kinugawa TD06sl2-20g
3in Full TBE
AEM 340lph Fuel Pump
Grimmspeed 3 port EBCS
Perrin 2.5in Inlet
GoFastBits Recirculating Bypass Valve

Edit* k&n typhoon intake

I am still in the process of setting up romraider and ecuflash with genuine tactrix 2.0 just need to install drivers and move some files around.

on a standard airbox/intake setup it should be easy enough to rescale the injectors assuming you have a wideband to make logs with. First job is read your current ecu and post up the file assuming its stock or was tuned by you.

Oops I forgot that I have a k&n typhoon intake. I can post the stock rom but I acquired a stage 1 lgt A/T 05 map that I might be able to modify with data logging.

Welp I'm back. I had gotten too busy to carry on with the project this summer but I am back at it again. Some things have changed such as I will be doing top feed conversion 1050cc from injector dynamics instead of the sidefeed 1000cc DW as well as I installed an AEM fuel pressure regulator. Everything else is the same I believe.

Hoping to find someone on here who can help me tune it, I had someone lined up, but seems they ghosted me cuz I hadn't responded in months. My next option is taking it to a tuner and dyno, but they want the green speed crap so most places aren't willing to do opensource anymore. Otherwise i guess it's trial and error. Crazy cuz I can do everything else down to rebuild my motor but haven't gone down the road of tuning yet.

I have been able to get romraider and some logging software installed, I have not used it yet, but the tactrix is genuine from the tactrix website, the $160 version. I have a friend who gave me a pretty aggressive base map that lives in Montana that suggested i take it and learn to modify it for my altitude and application for my target horsepower. I've since installed my AEM wideband with gauge and fuel pressure gauge mounted on my dash to make tuning easier. I'm not sure what the 3 pod style gauge in the center is, but i wouldn't mind some information shed on it because I've never seen one before.









Any help is appreciated! Thanks all.

Fairly certain my Blouch 440XT is just a TD05H-20G 8CM, which makes my setup fairly similar. What is most dissimilar, is the calibration ID you're using. You may or may not be able to modify the ROM I'm using and flash it onto your AT vehicle with or without changes in shifting behavior or DTCs. The rules on how this applies is a bit fuzzy, but it changes depending on year/generation of ECU.

Also, I'm a big fan of the TD06SL2 wheel versus the TD05H wheel when working with 18/20G and larger compressors. Your turbo is more likely the one I would rather have. Although, I'd get it in 7cm with the STS55 turbine.

Here is a cold start video that I made recently, after getting some miles in on my new 'mufflers' and dialing in alpha idle tables:
https://www.facebook.com/share/v/qaN3nF24HCJfGkH8/

BPT 440XT 8CM
UEL Headers
Catless, divorced downpipe 3"
3" midpipe with long bottle resonator
dual 2.5" to Yonaka mufflers (not chambers, they're muffler sized resonators)

ID1050x, 06/07 rails/FPR, AEM340, Billet TGV-less housings

GFB variety dual port thing, CX Racing FMIC, 3 port MAC valve

Cobb Turbo inlet, 3" intake, no MAF, SD with IAT in cold side charge pipe

Your hurdles to tuning for newer to the tuning experience include tables you've never heard of, and/or tables that are probably not defined in your definition set, such as low pulsewidth tables, decel fuel cut, and misc. other tables.

So, even if I posted up my ROM, and even if I posted up my expanded definition set, you would still be missing your definition set for your calibration ID, for the extra tables that arguably make tuning and driving more enjoyable. The solutions to this are to have them defined for your ROM, or run a compatible ROM that already has them defined. It's entirely possible that my ROM *could* flash to your vehicle and the TCU and other control modules may or may not care, but it would still need some work for the differences in setup. SD vs MAF, you didn't mention TGVs, etc.

Namely, you mentioned altitude/baro considerations. What I generally always do is get the system to target near as close as possible to the same pressure ratio at the compressor. This is basically trying to scale the target boost compensations to not always read out as what the target boost table looks like at face value, even with zero boost error, when you are programming the table. It's referenced as boost at 14.7 psia baro, but it's actually an absolute pressure target system. This is why I never log any 'boost' named pressure paramaters. MAP (not MRP) and boost error are the only ones you really need. In either case, at a higher density, lower altitude, the same pressure ratio can be a higher boost, making more power, but the same boost at a lower density/higher altidude would be a higher pressure ratio. If you're running near max wheel speed here, then what happens there? So I tune it to try to reach the same pressure ratios/wheel speeds at all altitude/baro pressure. This simplifies the system at the expense of maybe not having it consistently pushing the boundary of wheel speeds and pressure ratios (but accurately) at all altitudes, and thus making the most power wherever you are, for the turbos that aren't already tuned to the edge at sea level.

What's good on a timing table or fueling table at one altitude is good for another, they're airmass based. The difference in altitude is air density. It's calculating air density already. What's good here is good there for the basic load axis tables.

I'm going to post up my ROM and definitions on my own thread this weekend after I make some final adjustments to some tables, but here are some things to go off of.

I tune DBW to be 1:1 with torque request/pedal movement, and use 33%+ throttle opening, but primarily 63%+ for wastegate duty to dictate boost/torque/power. Better and more predictable torque response to foot movement, IMO. Rewards a sensitive foot, and with proper tuning of tip-in enrichment and low boost error, responds immediately to aggressive throttle movements.

I made a spreadsheet where you input the VE table, timing, target boost, fuel tables, SD multiplier/displacement, and injector settings, and it spits them out in respect to the load achieved assuming target boost table is accurate.

Anyways, what's your calibration ID? Can you post up your ROM? If you're using a user posted ROM from the forums, you can link to that. This weekend I can look at the ROM and see about defining the extra tables for you.

I will post stock rom here in a week or 2, I still have the cobb access poop installed. If it wasn't for that, I don't think it'd run very well, if at all with the mods I've already installed.

I will say that I am glad to finally have my wideband installed cuz I didn't know I was running super rich on pulls, like 10.9 on the AFR gauge. I can try finding the ID of the rom this week, but I am not super technologically capable. Edit* I can install whatever map I can get a hold of, but from my understanding, any map can be flashed, but if it works proper is another story.

My 14 years older boss is going to help me with most of the tech stuff to get me started cuz he is the one that got me interested in learning to tune since he showed me a little about it. Unfortunately he doesn't want to tune my car cuz he doesn't know enough and doesn't want to break anything.

Obviously anything is better than cobb and I can't wait to finally unmarry it from my lgt and sell it so I can put more money into quality parts and not worry about that EPA stuff since this isn't a daily any longer and is now a trailer queen. But for now I need a bandaid until I have a permanent solution since I still drive it once in a while on the street to keep fluids moving.

i wouldn't say 10.9 is "super rich" - if it was 9.9 then yeah way too rich but you can run the car quite happily at 10.9 if you have the injector duty to support it. There's really not much else you can do then until you start researching how to tune opensource then when you think you're ready take the plunge - uninstall the accessport and read the "stock" file off with ECUflash and start tuning it.

Okay guys, I was finally able to sit down this weekend and uninstall the accessport in favor for opensource. I have a feeling this forum is already making a comeback due to greenspeed and such. I am going to post up my stock rom in this reply. Albeit, I was a bit nervous to uninstall the accessport because i didn't know if the wagon was going to run at all but to my surprise it runs okay on the stock rom.

I still have a ton of things to do to it but its winter time and I should be able to tackle most of the job. Hard to do when you live rural, mostly off-grid, in the mountains of Colorado, so it's up to mother nature when I can finish my build.

Also jon7009, I would be willing to flash your tune over and make some logs. I am interested in getting into opensource, so with your guys knowledge, and my willing to learn, I am hoping to advance my knowledge to be able to teach others. Currently my TGVs are stock setup. I am running MAF and not SD at this current time. And as well the TD06SL2-20G does have the STS turbine wheel and ball bearing, I splurged where it counts I guess. We all gotta start somewhere!

bludgod, I realize now that 10.9 is not super rich, super rich is when I uninstalled the accessport and fired it up, the AEM digital AFR gauge was in the green, but no numbers on the display, and the aroma of unburnt fuel in the air!

I hope to have the build entirely done by the end of winter, early spring 2025. I am currently building an ej257 with CNC inserts to make it closed deck, and the usual forged internals. Right now I have 2 builder B25 heads ready to be rebuilt on a transmission table in storage next the the ej257 block, then drop off to the machine shop to adjust the bucket style valves to stock tolerance as well as a good hone couldn't hurt. That's all I have for updates as of now!

Hey again guys. So I have read the Subie Newbie Guide to Tuning and seem to have a better understanding of the subject. I still have some questions, but those will be answered in due time. I also understand with my limited experience and lack of knowledge, that the 'stock' tune I posted previously is not a stock tune at all, P0420 turned off, boost turned up to 16psi, and my timing tables all seem to differ alot from what my girls 06 Legacy GT has on her stock ROM. I am going to upload my wife's stock 06 legacy GT that I know for sure is stock.

Another update on the build. I decided to ditch the Grimspeed TMIC and go with a rev9 FMIC so this will set me back a little while longer. I was going to do fuel rail, injectors, and 340lph fuel pump this weekend, but decided I will install the FMIC and Fuel Pump. Next week is turbo install, and then the first weekend of January our shop will be closed and I'll have access to anything I may need to finish the job.

Once I have everything installed, I will test the local e85 and make sure it really is 15% / 85% content before logging and/or tuning. I really hope to have this done by spring time. Im also hoping I can ask questions here and get knowledgeable responses when the time comes. This community seems to be very helpful!

I've been tuning a 2005 LGT 5mt for the past couple months at 6500ft in Colorado. My build list is really similar to yours.
-ID1050x Injectors
-DW 340lph Fuel Pump
-Grimmspeed 3 port EBCS
-Perrin 2.5in Inlet
-GoFastBits Recirculating Bypass Valve
-AEM Fuel Pressure Regulator
--custom 6an ptfe fuel lines
-iag fuel rails with radium dampers
-perrin fmic
-blouch 1.5xtr turbo
-perrin uppipe
-catless invidia downpipe for the moment
-invidia q300 catback
-jdm tgv deletes (affects things a bit)

It was difficult to find similar build base maps, so I've been through a lot of trial and error.
I put together a decent map for it.
I'm doing a delivery job with the car right now, so the fine tuning is on pause, but I can check back in once it's over and I've ironed out the creases.
I referred to stock map logic and kept things simple for the most part. There are parts of stock maps across the years that are similar, so I figured it's safe to loosely stick to that logic. Subaru engineers seem like they know what they're doing.

Nice, always good to see another enthusiast close by. Whereabouts are you located? I'm in Nederland at 8466ft. I just got done putting the front mount intercooler on the vehicle. It took alot of modifications, but I was able to get everything where I want and the hood to close without rubbing.

I'm getting ready to put the injectors and fuel rail in this upcoming weekend. Then I just need to install the bigger turbo, put e85 in, and do some logging. Also I was able to install the 340lph AEM fuel pump this weekend so thats one less thing. Now all I need to do is put the 1050x Injectors, Injector Dynamics Fuel Rail, and the td06sl2-20g ball bearing turbo.

I noticed you have a manual transmission and I have an automatic transmission. I'm sure the map will flash over. If I'm correct and have been taught correctly, you can flash a MT map onto an AT vehicle, but not the other way around because of the lean/rich condition that occurs during a shift between gears in a manual transmission vehicle.

If you're ever in the area and want to meet up, send me an email, I always check my emails.

Alrite guys, I have finally got the front mount kit installed as well as I have a pump gas tune for 91 on stock vf40 pushing 18-21 psi a friend gave me making approximately 326hp at crank via virtual dyno. I have the FPR set at 55 psi base. Logs seem to say it's all good, IAM is 1.000 on WOT, no knock correction, and no knock learning. The Legacy definitely seems much happier.

After further investigation, the tune seems to be one that was uploaded here already as all the parameters match to a T, that tune being Russ-05 LGT or something like that, so instead of posting the tune, I will link the original thread so anyone wondering can download it.

I will eventually put the bigger turbo and injectors, but right now it seems happy and reliable. I might hold off on the turbo install and injectors until I have a built block because I feel on e85, it will make somewhere between 460-550hp and at those numbers, you'll blow up the stock engine in no time.

Getting ready to install a roll cage, 4 point harness, HANS & FIA approved Momo seats this weekend. This is gonna be a hot dog of car haha, put those Lamborghinis and Ferraris in their place on the track!

topic3986.html

So I've got another update, and just to save myself some typing, I'll copy and paste this from my Facebook:

"It may not look like much, but under all that wrapping is a Cusco Safety 21 6 Point Roll cage I purchased unused off of Facebook market place for $200. Homie even threw in a Cusco 4-6 point seat belt harness bar for free.

This particular roll cage is made from cold rolled seamless carbon steel which is what you want a roll cage made from. As well this roll cage is meant for a Lancer Evo-8 but since I do my homework and measure twice, I found that the dimensions fit the legacy wagon, who woulda guessed? I will however have to weld it instead of bolting it down because I don't have the seat bolts in the right spots. Luckily another one of my hobbies is welding and I'm not half bad at it.

I know this won't add any horsepower, infact, it will add weight which will reduce my overall horsepower, but safety is a priority when going for 500-600hp. When I go to install the Momo racing seats, I'll probably install the roll cage as the stock seats won't be in there and the Momos are easy to finagle in there once the bars are installed. Most of the interior will be striped out and carpets torn out. I'll probably leave the stock dash and some trim pieces."

End Copy/Pasted QUOTE:

So pretty much I'm to the point where I'm ready to finish up my build, I really want to have this done by spring 2025, I pretty much just need to drop the spare ej257 shortblock off at the local machine shop to get a CNC block inserts installed as well as a bore and a hone since once you put the block inserts, in deforms the cylinder walls and little so it's no longer a true circle.

As well I'm not sure when to stop updating my thread as I like to post my experiences for anyone else who might be traveling down the same road with same mods. I am going to eventually tune my own vehicle for e85 once the time comes. Also I do have some logs for viewing for the 'Russ 2005 Legacy GT" tune on 91 pump gas and outside air temperature was °46F. I will come back and edit this post to include the logs as I'm posting on my cell phone and the logs are on my laptop.

This is with a perrin short ram intake for 02-07. Stock 06 sti maf scaling.
Still kinda tinkering with throttle mapping, but results are good so far.

Thanks for the reply Flat4Life, as you know, I have an automatic transmission so I will need to copy the tables & parameters over to an AT map. If you're down, we can develop a new tune for open-source, we can just bounce the data/logs back and forth until we are happy with a high altitude map. Can you just post up a couple questions? What PSI, what fuel pressure, and what is the e85 testing at that you're tuning with? I have convinced my friend who owns the shop I work at, to invest with me into a dyno so we can do some tuning. Once this is done, i plan to play with it and study more as we both have a well developed understanding of maf, fuel ratio, algorithms, and equations. Will be the first tuner shop ever in our small town of Nederland if we go thru with it, which i think we are.
