Remove Cobb AP to be tuned with XRT

Subject: Re: lgt v2d
Ed at XRT has superior customer service and coming from me if you know me means something.
My 21psi was caused by a faulty boost controller.
The dyno that he showed was during the discovery of this issue.
We will find out what numbers I make on a actual dyno toward the end of the month.
I haven’t taken the time to post due to unbelievably busy.
I bought my car from a forum member that had a COBB tuner and maps from other forum sponsors. Logan and Bren.
Mods were: Racer X TMIC and charge pipe GFB BPV
Me and Logan went back and forth with my car and my concerns of how my car ran and the fact that the boost would run away past 20 psi.
He eventually capped it at 18 but I still didn’t like the way my car ran with the tune.
Turns out the previous owner sold me the car with a blown head gasket. Which didn’t show till high boost pressure leaked into the cooling chamber and caused the radiator overflow bottle to over flow.
I got the head gasket replaced and needed off of this tune. I also had bought a downpipe and exhaust but waited to install them when I was going to get a new tune.
After many discussions with my Dad (lives in Hawaii) about the information on Ed’s website, we decided to give him a shot. (My Dad built and tested F1 race engines for over 15 years.)
My XRT journey:
I contacted Ed and told him my backstory and that I wanted to install my new parts and do a tune. The day I installed my new downpipe and exhaust he had me send him a log from the COBB and then un-marry it.
I was not excepting him to be ready that moment and didn’t even have the software installed. Ed called me, remoted into my laptop and installed RomRaider and ecuEdit. I hooked up the taxtirx cable and saved he saved a stock ROM. (I do this shit for a living on servers and software build machines so when someone navigates through my laptop and software like I do it impresses me.)
He then proceeds to ask me if I have time to take a ride. (I mean like right now. I’m like fucking right I do knowing I have to go COSTCO ) He emailed me a new ROM and showed me how to install it and how to take a log. Then he tells me let’s go but ease into it. (Ok I’ll call you back….) Can you do a hot spot on your phone he asked? (Hell yeah I can.) So off we went
No bullshit when I laid that pedal down and took off on my on ramp to route 70 I giggled like a little school girl. 2nd gears responsiveness was beautiful. The car had no restriction too it. Third was even better. Big ass smile on my face. I loved my car all over again. And bam lost boost and a check engine came on. I start freaking out and Ed tells me that the car is fine it cut boost and throw a code. P0244 Wastegate Solenoid A Range/Perf (High) my boost was 21psi. He asked if the boost controller could be dirty. (Well what had happen was…. I had to drop the turbo to get a stripped nut off the stock downpipe when putting the new one on and I may have spilled a shit ton of antifreeze all over everything that was discounted.)
Besides this he said the logs look good and my car ran great
Sometime had passed (Like I said insanely busy) and I had took off the boost controller and cleaned it and put it back and received a new rom. I drove the car around and the timing just kept getting better and did a 3rd gear pull. (The one he posted and it had me at 21psi again. Yes it is a concern and no he is not cranking everyone up.) And it wasn’t until I tried to pass someone at WOT in 5th gear when the car threw a code again.
Ed said that he is not seeing the wastegate function properly in the logs and wanted me to take the boost controller off and give it power to see if it opens. Low and behold it doesn’t open.
This is why I have been getting 21 psi boost. I have ordered a new boost controller and installed it and that has resolved the issue.
I have not had time to get any more logs for Ed although he asked me and follows up every day.
I will keep everybody posted as always to how my build is going.

Over the many years of Remote Tuning (12yrs now as of 2006), the following information highlighted below is what customers try to attain before or during tuning and if these little ta-bits can be had, persons seeking a tune can be 100% ready and comfortable in tuning.
Before I start, allow me to briefly introduce myself in point form
Years of experience: 12yrs (as of 2006)
Background: B.Sc in Mathematics, Physics, Electronics | IT, Telecoms, Cybersecurity, Past Part-Time Tuning Instructor at a Technical College, Driver – lite sports, Cooking, hiking, family man, etc
Tuning capabilities: OEM ECU, SYVECS, HYDRA, LINK, Vi-PEC, Other EMS, Suspension
Remember Education is Power, once done right 🙂
Remote Tuning vs Physical Tuning
In starting, there is no difference between Remote Tuning and Physical Tuning. Remote Tuning takes a little longer and can capture events more easily and time is the factor to allow true fine tuning. Taking a car on a dyno and you have a prefect tune is not possible. Taking a car on the road for a few mins and have a prefect tune is not possible. If this was the case, OEM manufactures and racing teams will have limited research and testing. In others words, those countless hours you hear would just be lies.
Remote tuning requirements expected by the experience and knowledgeable tuner details that the customer communicates with his tuner in real-time as much as possible and communications channels opened extensively for tuning determination. That is, through you the customer, that knowledge transfer is achieve on any matter.
There are some who due to magazines and because of the bad information from many “Tuning” business seeking a quick way to make money, misrepresent real and detailed tuners who cares about Customer Relations, Service, Stability, Performance, Response, etc. This is a specialised service and should be treated so. That being said, there is no tune for $99, $199 or even one-of tunes. What took your OEM manufacture or racing team years to get right, just cannot come in the form as a pill. Please be wary. Because of the pricing war, tuning prices have been drivened down and the quality of tunes have gotten worst. I am sad to say, the customer now expect less and poor quality tunes are fantastic. This indeed is very saddening. In addition every man is a tuner because of having software in his hands to tune.
Dyno’es – Not created equally
Dyno’es are good. But it is a tool and you should understand this. Not all dynoes are created equal and not all are operated properly. The best Dyno to used is here – http://www.rototest.com/index.php?DN=1&Visitor=4
RRI Research Institute
Dyno Testing Information – http://www.rri.se/index.php?DN=29
Noting the above, this will help you determine what is used out in the field. This is extremely important!!!!!!!
The dyno must create a real life environment as much as possible and the quality of the hardware and software is key. That being said, a car dyno tuned should really spend some time on the road to gather data for stability, function and operations. This can take a few days or as long as possible for varying environmental conditions. Remember OEM manufacturers and racing teams. Please make sure your tuner offers this. Don’t be carried away with numbers.
Dyno usage – What it is good for
Remember and don’t take it as my word – Research, research, research. The tuning should finish up on the road, covering varying environmental conditions. Example, morning to night; hot to cold.
For those who love Dyno figures, having a correction of over 1 is useless. To verify Dyno figure, perform a quarter mile run and determine you realistic power figures.
Xtreme Racing Tuning – Drag Racing: 1/8-MILE TO 1/4-MILE CONVERSION TABLE
So let us get started.
Note: I am going to be precise as much as possible!
What are we talking about based on the subject?
Tuning the stock OEM computer that comes in the car. The majority stated below are also key points for Engine Management Systems or Powertrain Solutions.
Now after all of the prelim ground work been done, the next task is finding a tuner. Remote tuning should not offer anything less. Actually it should offer more!
The tuner should be:-
Testing should be done as follows:-
Please note the above should just wet your interest and should drive dialogue between you and the company/Tuner of interest.
From time to time, I do get questions referencing XRT. So let me take some time to answer them.
XRT does not adhere to today’s trend in tuning that is growing worldwide where attaining the customer money is key and providing great service takes second place. We believe the service we provided is important and is second to none.
Q: What makes XRT different to others?
A: XRT core interest, passion and precision is what makes that difference. To achieve a thumbs up from its customers or a thank you is its aim. XRT prides itself in not giving up in the most difficult situations or say it cannot be done. We let our work speaks for itself. We just love to take what is given to us and optimise it. Our main focus is giving that SUPERB Experience to the customer, leaving a permanent smile on their face.
Q: Why does XRT costs a little more when compare to other ETunes?
A: XRT does not distinguish the difference between Etuning & local tuning as others do. We believe in given the customers the best quality of service, time and support. This is attest by our valued customers. XRT believes in full customised tuning, even to be there online through the process by the use of remote software like Teamviewer for Live Tuning. We do not offer off the shelf maps with minor tweets or one rom for all cars with the same ECU ID. We also believe in fine tuning to suit your car configuration and your needs. We brought this process over from working with EMS and with customers who race their daily driven cars. Please see our tuning strategy below that makes this all happen….ingrained in out DNA.
Q: What is XRT support service(s) and why is it different to others?
A: We give close to 24hrs of support through Teamviewer, Email, Whatsapp, BBM and BBM Group. Support is fast and reliable. Customers are welcome to even call. In all reviews, XRT is praised for this. It is above standard when compare to the tuning/tuner industries. We provide and request constant feedback from the customer and revisions of roms to reach optimum performance.
Q: What makes your Transmission tuning different to others?
A: XRT takes the time to develop Transmission tuning based on feedback and countless customer reviews to make that difference. In addition, due to feedback, support is given to make changes to suit the car and the customer.
Q: What other services do XRT offer?
A: XRT collaborates with its customers for troubleshooting and diagnostics through data logging and reviews. XRT also offer support for upgrades, even Project Management Services.
Q: If my ECU is not defined or a definition is not available, can you support it?
A: Yes. we create our own definitions for full support, even able to offer better support as a tuner compare to other tuners using Cobbs, Ecutek, etc. We offer a more reliable and safe tune. This is attest by some of our customers who have replaced their Cobbs or existing tuners who used Ecutek to tune their projects and not getting the correct, safe and reliable results.
Q: Do you tune turbo cars?
A: Yes, we do. XRT was born out of WRX/STI tuning. Actually more STI tunes that any other model pre XRT founding. We have work on projects up to 600HP and consulted up to 1000HP.
The following is our recommendation racing fuel for performance and track.
VP100 – Street Legal Power and Performance
VP100 (aka StreetBlaze 100) is a 100 octane unleaded gasoline specifically engineered for high-performance street vehicles including luxury sports cars, muscle cars, street rods, tuner cars, sportbikes, cruisers and more. Oxygenated with ethanol, this CARB-legal fuel is environmentally friendly and street legal in most areas. It contains no metal compounds and won’t harm catalytic converters or oxygen sensors.
VP MS109 – Racing gas for any type of racing
R+M/2 (Octane): 105
VP RallyMax – XRT Favourite Racing Fuel. Takes a lot of timing and very powerful. All types of racing.
R+M/2 (Octane): 97.5

Subaru Tuning that affects CVT Operations & Performance by Xtreme Racing Tuning (XRT)
XRT have continue to master the operations and performance of the CVT through tuning and customer feedback and based on the results, we are offering that edge in tuning CVT models like what we did to the 5EAT and the 4EAT.
Generally, the following are expected when tuned (The Transmission Computer is not tuned):

For a few years now, customers been approaching XRT on a retune of their Cobbs’ AP, but we do not support the Cobbs AP at this time. We are not sure if we will every be due to a refocus into to Motorsports and Engine Management Systems, but knows such technology has its place in the industry.
Lets review my statement above.
I have been watching Rallying, Grand Touring, Touring and many other sports where named manufactures (BMW, Nissan, Porsche, Subaru, just to name a few) never reprogrammed their ECU’s to run those cars for such Motorsports, even when the power is close to stock and I always ask myself what were the reasons why this was done. As I matured in ecuflashing, Instructing in EMS courses and tuning EMS over the years, I came to understand why this is so, even if such technology was tempting, accessible and cost effective.
The Stock/OEM ECU/ECM:
For a quick read, please review XRT owned link – EMS/Powertrain review thoughts
If all of the above continues to hold true going into the future (and I do not expect it to change due to production cost of vehicles), why then would I want to reflash the Stock/OEM ECU/ECM and as a tuner, not have the best in tuning for a very efficient and responsive engine?!?
That being said, we focus more on EMS tuning for specific operations and functions for an engine needing that edge in performance and development. The necessary skills, strategies, experience and mental aptitude is so extensive & intensive in this type of tuning and support, that one can achieve the highest goals needed for sports and performance tuning, in relation to the configurations of the car, driver needs and environments.
With such focuses highlighted and discussed above, XRT by its nature and having such backgrounds in these fields (tuning and support), can seriously, precisely and accurately provide reflashing services that is Top Class to none, taking every bit of time to provide the finest tunes in tuning your car, regardless if in Motorsports or every day street driving; especially when it comes to reflashing using Open-Source technology for tuning.
Bringing along those core aptitudes, customers can gain a new experience in tuning support and better operations of their cars. That is, achieving great review in whatever we do when working with the clients. One could accurately say we are customer oriented 🙂
So what do we do?
So…. out of what we do, we just do it better by taking our time, which is reflected in our tunes and support that makes us different to other Tuners and tuning support companies. Logging and communication with our customers defines the outcomes.
Atmospheric Pressure: 1017.3 hPa | IAT: 24C >> 22C
I was referred to XRT by a fellow member (golferdude1087) for a tune for my 5th gen LGT. I contacted Ed and he responded immediately with answers to my questions, helped me get setup with the necessary software, and sent the initial tune. Out of the box, it was a massive awakening for the car. Its the first time this car put that big of a smile on my face and even impressed my friend that drives a tuned 3 series. After a few days of back and forth with logs and tips, we are now on version 3 and it runs great. It pulls hard and smooth throughout the entire range and still gets decent mileage with “spirited” driving. The logger “dyno” numbers say about 275hp/340tq (wheel) compared to the stock 265hp/258tq (crank), a significant increase even if the software isn’t accurate. His tips on things to look for and areas to improve give me confidence that the tune will be safe too. I would definitely recommend an XRT tune to anyone looking for reliable power.

Subject: Low end torque
Low end torque is much improved, to the point that small maneuvers like passing or cornering can be done without getting into boost. Accelerating from low rpm’s is also better, letting you stay in gear when you’d normally have to downshift.
Subaru Tuning that affects the Torque Management Operations & Performance of the Engine by Xtreme Racing Tuning (XRT)
XRT continue to MASTER the Operations and Performance of the transmission (5MT, 6MT, 4EAT, 5EAT, CVT) delivery of TORQUE & POWER to the ground in any models utilising the 32bit ECU (Legacy, Impreza WRX & STI, XV, Crosstek, etc). This is seen through tuning, customer feedback and REAL results based and posted all over the internet, including here on XRT.
Addition reviews are here for Auto Transmissions:
Torque Management are already patched in those tuning!
Generally, the following are expected when tuned (The Transmission Computer is not tuned in the Automatic cars):
Please remember that even Manual Transmission models are affected and are able to accelerate and spin tires easily and freely. Please disable Traction Control.
What a great way to start the day!! Now I am officially a part of the XRT Family and wow did I wait too long to make the change. I will do a write to explain in depth but I must say that at stock boost levels (which I was running way higher before) the car is a new machine In Every way!! It feels so great I can’t stop smiling !😬 The car just wants to go! The power is so linear and smooth and are used to have an issue with some choppiness throughout the RPM range which is completely gone now!! Thank you Ed so much for the genius that you put in to every car that you work on the customer support and the knowledge is unsurpassed everyone should be on a tune by Ed I don’t think anyone one who isnt really realizes how much better their car will be because of all the Forst comments from people saying oh when you buy your car/Subaru you need to buy an Cobb, WRONG!!!!It is going to be my goal to change all of that! Have a great day everyone I will update more as soon as I am out of work
Thank you so much Ed!!! You are true genius with tuning!! And also such a great person to work with!! Can’t wait to see what we can do with this car as time goes on!! I have people already calling me for rides so they can see lol.
So I don’t know if everyone knows but I have left Cobb and have moved over to XRT Tuning. It is still the beginning as we are doing a lot of data logs to keep fine tuning and adjusting different parameters of the ecu but I can honestly say that I have never had my car feel this good!! The response of the turbo and the engine used to have quite a delay and would stop making power around 5000rpm. Also I was running 19-20psi. As of right now I am at stock boost levels and I have much better response from the engine and no delay in the drive by wire system and I am also happy to say I am making much more power at way less boost and the car continues to pull and wants to go and keep pulling past redline the power delivery is absolutely incredible and we are nowhere near done tuning it for anyone local who does not believe you are more than welcome to meet up with me and feel it for yourself and see how a really great tune can make a car feel. I am running much safer and not overly rich as the prior pro tune was running. It also got rid of the so called “STi shudder” that people say is common lol. I will continue to update this post along the way so everyone can see what happens and for all the Dyno guys after I am at a point where I want to be I will get a pull done to show the numbers. I highly recommend XRT tuning he is a genius at what he does and ask anyone who has been tuned by Ed and I am sure you will get the same response and his customer support is like none other. I regret not doing this sooner but I Believe everything happens for a reason so the prior moves led me here and I am very fortunate to have someone as knowledgeable and talented tuning my vehicle! Thanks for reading 5th gen fam. If anyone wants to PM me to find out more details feel free.
As posted on the https://www.facebook.com/groups/SubaruTuningInternational/
Well from the research that I did and talking with ALOT of people at all the shows and different forums the tuner that did the pro tune was regarded as One of best tuners around these areas! 😂 He has done a lot of subarus and quite a few 5th gen LGT’s. I am not trying to bash him but after seeing how poorly the car was running and how everything was set I’m positive that everyone should be tuned by you Ed. The way my car has felt from V1 is still better than what he did! Now that we are in a better state knowing how the car is running and the way you have adjusted everything I am driving around with a smile from ear to ear!! I have caught a few people at stop light look at me and probably wonder why a crazy person is behind the wheel but that is because they have never been truly happy behind the wheel of their car , which I can proudly say that I am and I know that things will keep getting better as she learns more. I also want to thank you for the unbelievably great customer service/support that I have gotten and continue to receive. It is so much better than anything I’ve delt with since starting with my car. Thank you very much for being such a great person and a genius at your craft!! I can’t wait to see what’s next!!!!!!!!!
Lol I don’t mind having at least a mini stroke from happiness!! It’s so wild to me that there is still more to come!! It is such a pleasure to work with a tuner as great as you because out here it would be like pulling teeth to make the tuner even give you one revision.
Just a little teaser. Waiting to see the 1/4 mile time. Dbw aggressiveness been crank up a little and so did the boost 4400+. Awaiting logs to see the flow pattern.
Graph shows the TA Protuned Cobbs running more boost vs XRT tuning running a tab low boost in mid range and much lower 4800+. All power is gain by TQ Management, Dual AVCS tuning, reduce fueling and ignition tuning. Again I am waiting on further logs to finalised the tune.
Luis please your last throughts.
This last update again felt amazing
!! The Power delivery is so smooth and so linear it feels as the car just wants to keep going if there wasn’t a redline in place lol. It’s amazing how responsive the car is with the DBW and Turbo response also the way the car sounds is different and more aggressive sounding when getting on it it makes me smile even more LOL To know that there are still things that can be adjusted is wild to me because of how far this has already surpassed any of my expectations and it is light years beyond the tune that I was running prior! Ed you are a true genius and are able to do things with a tune that I have never experienced and I know by all the people you have tuned and how happy everyone is that this is a common occurrence why anyone would not want to go this route is beyond me because from now on I will no longer have any car without being tuned by you! I will update more as time passes thank you again Ed and thank you everyone for following this post stay tuned there is more excitement to follow!
Thank you Ed!!! I was admittedly one of the people’s who get into believing you need a cob if you have a Subaru and did not do enough research beforehand. I am a true believer that the power is in the tuner but it must be an experienced tuner with a great track record like you!! To this day my car has never felt this good and the power be so liniar. I can’t wait to load V8! I will be updating after you and I speak.
P.S. That is another HUGE difference, the customer service and support is dramatically different with you because you care about what the customer is telling you and want the true feedback so that you can see how the car feels to the person. Most tuners just set it how they have been used to setting it on other cars and send it on its way. Thanks again for all your help and being such a great person as well as a truly talented tuner !!! Anyone who wants their car to perform the way it should and better than it ever has needs to be XRT Tuned!!!!!!
