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!!!!

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

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.
