Perfect,

Added to compatibility list.

I've seen them around several of the forums I used to frequent. I think it's an awesome idea, especially since we all share a fairly similar car (thanks Subaru :P)

Feel free to contribute, some tips/tricks are quite cross-generational/cross-platform. I may just make this into a general KB thread.

Default Disable Hill Assist

I've been bugged by several people, and even after reading documentation myself, this was kind of confusing.

*disclaimer* All information I know (unless otherwise stated) is gathered from owning my '11 STi Sport-Tech Canadian Model. Please take extreme caution, and use any information at your own risk.

Problem:
MY11 and possibly other GV/GRs have a "hill assist" option that brakes when the car is on a hill, so you have time to clutch and gas properly and take off without burning the hell out of your car. Problem is that the brakes are often held on even after you take off.

Solution:
- Get in the car, sit in driver's seat (make sure all doors are closed)
- Press the VDC/TCS button and hold it
- Insert key into ignition and turn to ON (2 clicks)
- You should see the traction control light come on, keep holding the button
- Within about another 10 seconds or so, you should see the light go yellow, keep holding it
- when the light goes out, THEN you let go of the button (within 5 seconds)
- When the process is complete, there will be no visual/audible indication, take the key out of ignition

Notes:
- To Test: start car, wait for initial systems check beeping to stop, you will notice the hill assist light is on (near the airbag/srs light)
- You can alternatively check by (safely) parking on a hill, and see if the car immediately rolls back
- If your car loses power, or ECU is reset, you should NOT have to re-do this, as it will be off completely until the process is cycle'd through again

Tested Compatibility:
- MY10 STi
- MY11 STi w/ Sport-Tech package

I'm having doubts about the a/c disable for MY 12+ 2.0i models. I tried it again today, and could not conclusively determine if the system had disabled itself.

test it on your car by having A/C enabled, press the button to disable, wait for 10 mins or so, re-enable manually, and listen for the compressor/relay click. Open your window, and park inside a parking lot if you have to.

For those that know but are not sure about the problem.

Stumble Fix under acceleration for GR/GV STI

Disclaimer: This is more than clicking your seatbelt or resetting your ECU, it may permanently damage your engine or fueling system if done incorrectly.

Problem:
This is the most prevalent issue with GR/GV STI's, our fueling system creates a water hammer pulsing effect which makes the car run lean and stumble from 2.4k-3.1k RPM (vehicle specific) during a light/WOT acceleration. For those that use OST, you may also notice your check engine light comes on if you cruise between 2.8k-3k RPM in 6th gear more than a few minutes with the code being P0171 of "Lean on Bank 1/2" or P0296 "Post catalyst fuel trim system too lean" . This will also fix that issue.

Solution:
By lengthening our fuel line, it disrupts the pulse in the loop, creating a much smoother fuel delivery to the engine.

This guy will do a much better job at explaining than I ever will, pictures included.

Tested Compatibility
- MY09 STI
- MY10 STI
- MY12 STI w/ SPT Package

Worked for 3 cars, all with the same effect of fixing the stumble.

Personal Conclusion
Worked for me, I had this problem under WOT as well as light load, difference was night & day, as the guide mentions, be sure to reset your ECU or if an AP is available, retune the two maps as shown. The full benefits will not show unless you retune as opposed to resetting.
Please change notation to follow syntax of above KB articles (headings/information syntax), I'll add link to the first post once changed (also, whatever you'd like to title article). All KB articles, should not contain unnecessary information/personal opinion.

WARNING: For anyone thinking about this mod (I personally don't have it, after STGII + protune but some of you may) consider that you may have to be retuned or you will run lean in the higher rev ranges due to the extended length of the fuel line. This is not only to reap the "benefits" but also to protect your car during those higher ranges.

This issue is also not usually noticed w/ stock setups, and and if observed stock, should probably be a warranty item you can take up with your dealership.

This will not make your car run leaner with the added fuel line, you're adding 3ft, not a mile. Just be sure to prime the lines before starting the car. The car will correct itself with a reset ECU, and run even better with corrected maps.

For those with stock cars with this issue, it is not a warranty item, but a design flaw, you have the option of doing the mod, but is best to bring it to the dealership.

Again, "may have to be retuned or you will run lean in the higher rev ranges due to the extended length of the fuel line."

YMMV.

That aside, added to list of KB articles. Credited.

Sorry, Bud. Confirmed that MY 13 2.0i will not allow me to disable a/c on defrost mode. I tried it this evening, and there was definitely something bogging down the engine even after I tried to turn the a/c off. Either something else is running in the background (in addition to a/c) while on defrost, or the a/c didn't disengage. I'm thinking it's likely the latter, given the cold air blowing out of the vents.

Since MY 13 2.0i is just a re-badged MY 12 2.0i with minor edits, I suspect the same holds true for MY 12 2.0i.

Regarding the hill hold function, i don't understanding what is the issue you are experiencing?

For me, it only holds for 1-2 sec on a hill, then it will roll back. It allows just enough time to take your foot off the brake pedal and move to the throttle and give gas. Then, it usually takes off smoothly. If you are really quick, then you might just end up rev-ing the car a little before taking off, which sounds fine to me. If you use the e-brake method to hold the car, you will end up with the same result (slighting rev-ing it before releasing the e-brake for take off).

I guess I'm just trying to understand what do you mean by the car would still apply the brakes after you take off. Do you see your brake lights on or something?

Does anyone know a way to get around the A/C automatically turning on at "Auto"?

Most of the time I just want to go from "Fan off" to "Fan on" and I don't want the A/C on. But if you own a GR/GV, you know that the "Auto" function is the first choice on your dial. I find it pretty annoying having to manually turn the A/C off everytime I want to just have the fan blowing.

Thanks!

nope, but anyone's who decently quick to engage, will notice a small braking sensation.

this is only if you have climate control. if it's turning A/C on right away, then you need to change the vent position to something other than front defrost, OR just manually disable A/C as per the KB.

Still showing, Dude. I think you may have accidentally removed the seatbelt chime thingy compatibility by accident.

And, just to show that reading the ****ing manual actually does work from time to time, I present to you the following excerpt from the 2.0i manual:

Whodathunk that reading the ****ing manual would be so ****ing logical?

I need new glasses.

For MY07 impreza 2.5i, to disable the seatbelt chime you need to have the car running, in/out the seatbelt 20 times, then turn off the car, remove key and start again.
