Cobb AP Pro Tune & XRT: The Differences

http://www.xtremeracingtuning.com/forum/viewtopic.php?f=115&t=770#p2391

OK we are close this one was good!

Town driving–Throttle response is still nice and strong-nothing changed there and that is good. A little jumpy in S# at ~25% throttle around 3K in 2nd and 3rd BUT** it’s very responsive to input and i don’t have the most steady foot on bumpy roads:-) doesn’t do it in S mode so yeah…my foot lol!

3rd gear pull– Only 1 single instance (single cell) of ping (-1.5) right before peak boost. a few -1.5 cells as I lifted off throttle at 6000rpm. Feels Strong.

How it feels on the 3rd gear pull–pulls harder as the boost spools up–perfect!. It feels like it hits a shot of Nitrous about 4600RPM as it transitions from 8.5degrees to 10.5degrees of timing. It’s subtle, not a surge, but I thought I’d point that out.

Roll on acceleration about 3000rpm—amazing in all gears. I don’t really feel that transition in this circumstance.

2nd gear is just nuts. I never really tried it before at WOT. SO yeah, nice one!

Shifting–under load, nice and sharp and quick. I don’t know if it’s possible to tune this—-> but it would be nice for the trans to respond faster to paddle inputs, especially at light load around town. No big deal though;-)

Alright, well where do I start? As we are getting close to the end of the tuning process I’m thoroughly impressed. Ed’s knowledge and feedback to my queries has been fantastic. He’s quick to respond and I challenge any tuner to provide such good customer support! Feedback is nearly immediate and revisions come daily (sometimes more often!).

I urge any Cobb tuned customer to consider XRT. If you have an 5EAT or if you are Cobb tuned on Canadian petrol, you need to contact XRT tomorrow!!

My Cobb stage 2 provided predictable, modest power improvements as advertised from Cobb. However, as predicted, the pinging (feedback knock, fine knock learning) was endemic, over all grades of petrol. Only after a couple revisions he had the power far above Cobb’s tune, and a transmission that provides strong, fast shifts. We are onto Rev 5, and the power keeps building and I’m getting zero pinging under all conditions, on standard Canadian 91 petrol! And the shifting and throttle response are unreal. Night and day over an Off The Shelf tune…. BRAVO Edward!!!!

By the way The AVO turbo kit and the raptor supercharger kits are not available for the 2015+, due to no tuning or fuel pump solutions
Thanks to XRT Ed, I have been given the confidence to move forward with the project. I live by multiple Subaru tuners, and was turned down by all of them. Ed said he was up to the challenge, and I like working with people that have a can do attitude

Now the car is running great. I have made some decent pulls to collect data for ED. He is doing an outstanding job!!! This is the first time anyone has tuned a 15+ NA for turbo and there are a lot of hurdles to overcome. ED is knocking it out of the park. Every time he sends me a ROM it gets better and better. His CVT tune is awesome, makes it feel like a sports car not a grocery getter.

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

Remote Tuning

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)
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
RRI Research Institute

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.
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.

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, if possible, 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.
  • 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.
  • Can 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 with advance CVT indirect tuning.

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.
