XRT ECU Stage 1 Tuning

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.

2015+ WRX/STI: Remote Tuning Support

Image result for 2015 subaru wrx FA engines
XRT Remote Tuning Support for the 2015+ WRX/STI, through ECU Reflashing will be a new addition to our value added services, where customers who are looking for that X in Calibration, Response and Performance, can use us to fulfill their needs, knowing that we offer Precise Calibration and Superb Enhance Customer Service to accomplish their tuning needs and goals. We believe based on our accomplishments of 11yrs, we can achieve great results very quickly, safely and efficiently –
The addition of this new service will means that it will play very well into our aims; where over the years XRT have been developing its tuning strategies, for example, where persons using Cobb & EcuTek has made a switch to XRT and cannot believe how well the car works on stock boost. By doing so, we have put those others solutions to the test where those same solutions are running Stage 1 and 2 mappings. We just spend more timing Calibrating (Fine Tuning) and tremendous amount of logging and replaying logs in a format one can see issues and determine where, what, when and how a technique is applied. Many wonder how this is possible but the latter just shows you. We really care about real tuning (Calibrating) like a surgeon.
Once there strategies are applied, and especially on the FA platforms, we can expect to see the XRT Engine Response and Performance (XERP) increase tremendously in comparison to the competition. We do not follow or adhere to the general trend of tuning below. We believe in fully calibrating the Car for its environment, modifications and the owner’s needs.
