My experience with XRT has been amazing.

At first, I had a stage 1 OTS cobb tune and loved it. That opened the car up to what it was capable of and once I realized that, I got hungry for more. I saw a post about XRT and started to get incredibly curious on all the gains someone received from them. Once I emailed XRT(Ed), he informed me BlackBerry Messenger(BBM) is how he chats with all his clients. He is based in the Barbados so we can call each other on BBM or Whatsapp to avoid oversea charges. After tons of research and seeing no other tuner is pushing out that type of gain with my mods, I sold my AP3, and was ready to start.

Ed informed me to download Team Viewer so he could remote into my machine and download all the applications needed to setup the logging parameters and created the file structure for logs and roms. Even if you are not a newb to open source tuning, LET HIM SET IT UP. It will be easier for everyone and if there are any issues, he is perfectly capable of correcting them.

Once all the preliminary stuff was done, he sent me a version zero rom to show me that my car is capable of a lot with stock boost. My jaw dropped. Throttle response was insane, the torque was there, and you can clearly feel that the car enjoyed it much more than the Cobb OTS tune. v0 vs Stock - 3rd Gear Dyno SAE.png

As the process continued, you could feel the car run better and better as the days went on. He transformed my car so much, I would rather drive my car to work, Downtown Washington DC, than take the train. I feel like a little kid every time I hit boost now.

With XRT, they could get maps out same day or next day. Ed is very good with being responsive within a few hours and letting you know if you need to check something on your car or not. He is very particular about how he tunes a car and how it is running. Making sure your car is mechanically fine is key to having a smooth and successful tuning process. Overall, he is a skilled and very knowledgeable tuner. He changed my car from a slow non- responsive 2011 LGT into a responsive torque monster that I enjoy driving every single day. Boost comes on smooth, the car moves when I tap the gas and everything on the car feels great. It took about eight to nine revisions before the car got where it needed to be. He is done with my Subaru for now, but he will be doing my GF’s 100% STOCK CVT Crosstrek and I am sure I will see major improvements there! I attached a Dyno sheet along with Ed’s Virtual dyno of the same dyno pulls.

XRT Subaru CVT Tuning

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):

  • Quicker shifting
  • Firmer shifting
  • Appropriate gear selection for less labouring or load on the engine
    Less ping/knocking due to the transmission wanting to be in high gear all the time.
  • Less pedal moving to make the transmission shifting
  • Better fuel mileage
  • Easy over-taking and maneuvering due to quicker acceleration due to the above points.

XRT Offers additional stages for CVT tuning.

  • Stage 1 – offers greater shifting and operations. This is the mode many requires if you want to have full control when the transmission shift for hill climbing, racing, over-taking etc.
  • Stage 2 (Full Sports Mode) – offers increase response and less throttle lag. Direct throttle control. Now you maybe able to spin those tires on moving off or get that maximum torque to the ground. Transmission Cooler is recommended if you plan to drive her hard

Cobb AP Pro Tune & XRT: The Differences

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:

  1. By design is just enough to support all functions of the stock car
  2. Cannot log at a high rate. This is needed to capture events for remediation
  3. Not powerful enough and high storage areas for Advance Engine Strategies and Operations (Antilag, Fuel, Ignition – all inter-related to multiple level mapping, Complex features and operations). Such enhancements comes in the form of FPGA’s implementations, dedicated CPU Processors per functions and the type of Processors used. For additional reading, please visit the following link –
    1. https://en.wikipedia.org/wiki/Field-programmable_gate_array
    2. https://www.design-reuse.com/news/6629/actel-fpgas-development-multiple-race-car-engine-control-units.html
    3. https://www.xilinx.com/video/hardware/what-is-the-difference-between-an-fpga-and-an-asic.html
  4. Do not have enough Inputs/Outputs (I/O’s) for additional functions for a sports car
  5. Ability to program in the field with new strategies for performance operations and access to new features. That is, changing the core functions of the device itself. Kind of like model versions upgrades all happening with just one devices without internal hardware architecture changes.

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?

  1. Provides the greatest level of known support to clients in the tuning industry- http://xtremeracingtuning.com/forum/viewtopic.php?f=122&t=670
  2. Does not distinguish the difference between Local & Remote tuning
  3. Seek the best possible reviews as much as possible for the finest work in tuning of client cars – http://xtremeracingtuning.com/forum/viewforum.php?f=48
  4. Provide accurate detailed Diagnostic support throughout the tuning process or XRT Live Group supports
  5. Very log oriented. That is, clients must log for fine tuning; as much as possible. Logging defines the tune!
  6. Custom Tune all cars starting from Base-Line tunes to fine tuning. We do not make OTS (Off The Shelf) tunes the final tune.
  7. Work with the client closely in the optimisation of the tune while fine tuning.
  8. Encourage and insist greater levels of communication between XRT and clients. This provides the best possible experience in tuning and support.

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.

 

AndrewC review on his XRT Tuned 2011 Subaru Legacy GT 2.5 6MT

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 Torque Management Patch (XTMP)

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):

  • Quicker shifting
  • Firmer shifting
  • Appropriate gear selection for less labouring or load on the engine
  • Less ping/knocking due to the transmission wanting to be in high gear all the time.
  • Less pedal moving to make the transmission shifting
  • Better fuel mileage
  • Easy over-taking and maneuvering due to quicker acceleration due to the above points

Please remember that even Manual Transmission models are affected and are able to accelerate and spin tires easily and freely. Please disable Traction Control.
