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.

Remote Tuning

Over the many years of Remote Tuning (11yrs 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: 11yrs (as of 2006)
Specialisation: Subaru
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

Dyno Testing Informationhttp://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

  • Dialing in areas that needs cruising time
  • Dialing mods that changes the dynamics quickly or drastically
  • Safe area to tune.
  • Ability to see changes easily on a close to control environment. The dyno facility should be controlled as much as possible. This can minimised the number of dyno pulls. Example, Humidity, Temperature, pollution, Noise, etc

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.

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.

Mechanical needs

  1. Try to understand what tuning is. Tuning allows the car to compensate for the environment for which it operates in. Either for general purposes or having high performance needs.
  2. What is needs before tuning – Mechanically
    1. Full Engine Oil service
    2. Spark Plug change
    3. Check for air leaks in the intake and header system – A boost test should be done.
    4. Clean the MAF sensor
    5. Throttle body Clean
    6. Injector Cleaning. Professionally cleaned or using a good quality Injector cleaner
    7. Verification of all necessary sensors and solenoids through logging – Xtreme Racing Tuning – XRT Diagnostic/Troubleshooting Support Service
    8. General maintenance of the car – Brakes, Coolant, Transmission oil, Gear oil, Tyres, Alignment, etc, etc
  3. Tactrix Openport 2.0 Cable
  4. Ecuflash software
  5. Romraider Software – Romraider.exe | Latest RomRaider LOGGER Definitions

 

Tuner needs


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:-

  1. Very well Experience
  2. Should have excellent Customer Service – The community should highlight this.
  3. His work broadcast and can be seeing online
  4. Excellent Customer Reviews
  5. Very knowledgeable about his job and the car to be worked upon
  6. Excellent knowledge in Diagnostic and noting issues before issues gets out of hand
  7. Excellent Support Services – Phone, email, messaging
  8. Excellent communication skills
  9. Quick to respond within 4hrs
  10. Understanding of family committment and factors that affects the tune
  11. Excellent abilities in setting up computers and instructing/lecturing
  12. Be quick and excel in highlight your tune to you with graphs and data, if needed.
  13. Etc etc etc

 

Testing/Logging


Testing should be done as follows:-

  1. Follow your tuners direction precisely. Don’t do more than what is needed. If otherwise, seek advise.
  2. Relate any issues to the Tuner, even if you do no think it is important
  3. Safe area
  4. Cruising to spirited driving in areas to create minimal to high load stress on the car. These are mentioned below.
  5. Hills
  6. Varying environment conditions
  7. Flat roads, especially for dyno pulls. When performing dyno pulls, do not sit waiting for the car to heat soak. This will reduce power tremendously.

Please note the above should just wet your interest and should drive dialogue between you and the company/Tuner of interest.

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
