Subaru Ascent Tuning

XRT is the only Tuning company beside Cobb Tuning to demonstrate it tuning capabilities and the release of tuning information to the World before any other tuning companies. In fact, tuning companies requires Cobb Tuning to support these models. XRT don’t! Thats being innovative and creative!

Please also note XRT is a Cobb Protuner and we support tuning of the Subaru Ascent using the Cobb Accessport.

In respect to our research and development (as shown at the very below) on the Subaru Ascent & the FA24DIT operating in this vehicle, we are offering Stage 0 and 1 tuning support to owners with the following requirements:

  • Tuning that does not require a device to be installed in the car
  • Improve driveability with clear objectivity in engine response
  • Improve Fuel Mileage
  • Reduce throttle lag
  • Better sounding throaty engine
  • A little more pep (Stage 1)
  • Improve CVT Operations

The tuning is really considered for those not liking the small little issues as highlighted in our XRT Subaru Ascent Whatsapp group – https://chat.whatsapp.com/E1dPtXGgn3oEJAEm6P3aeU

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

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!

http://www.subaruxvforum.com/forum/engi … ost1758153

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!

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.

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.
