PaulH – 2011 JDM Subaru Impreza WRX STI A-Line 2.5 5EAT

Reviews:-

Car feels amazing during pulls and can’t wait to get it on a nice stretch of road

The car is now feeling much better than I imagine, it moves and feels GREAT threw out the entire power-band, no more waiting till after 5000rpms to feel being pushed back in the seat. XRT is the best in customer service, turn around time and great advisor and tuner. Turn the car from slouchy to speedy

Initial Reviews

Well I’m going with XRT as far as the tuning goes. His customer support and reviews of his tunes are very good.

http://www.subaruxvforum.com/forum/engi … ost1754113

XRT has you logging constantly to give you a custom tune for whatever mods you might have installed. Is it a little pricey. Yes but the product along with his customer support is AWESOME!

Just a little update on the tuning I’m receiving from XRT.
As of now I installed the updated ROM he sent me (haven’t driven it yet) but I can say that the prior one was AWESOME! Small issues from when I open it up from a stand still but when I need passing power it’s there!
Tranny behavior is near perfect! And besides all of this he’s their with better than excellent customer support!

http://www.subaruxvforum.com/forum/engi … ost1761042

Ed, all I can say is WOW! This latest tune v0c3 is by far the best you’ve done! Great power off the line & great power for passing. The rpm’s while cruising 70 or 75mph are great for mpg!
I’m not looking for WRX power btw. I want the best of both for the motor I have and it’s almost there! GREAT JOB!

With the current mods and now fuel review, the car is running very lean.

Fellow Trekkers. I’m not here to bash anyone but I have to say that Xtreme Racing Tuning is AWESOME! Since I’ve been working with them I’ve logged a bunch had a bunch of new ROMS (tunes) sent to me and their customer support is by far the BEST! These are not one off tunes. They are dialed in to how you drive!

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.

 

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.
