    Understanding some ECU fault codes

    That code and going up hill in a high gear is usually over boosting. 
    Ie the waste gate and solenoid range isn’t enough to keep the boost at target. 
     

     

    maybe 57 is due to limp mode but 47 could be anything. 

     

    Ah right. So is this any indication or a bad solenoid, or bad connection, maybe solenoid needs cleaning? 
    Come to think about it, I was in fourth gear and just planted it.

    Long story short:

    driving home from a 3 hour drive, driving up hill on a motorway, wound up some boost and the car surged forward awkwardly, slowed up and went into limp mode (TC off light, check engine light, SI drive light flashing etc) 

    cleared the lights with 5 stop starts. Car has been driving fine, but I quickly and luckily got my car scanned 5 mins later. These codes came up:

     

    Engine Control System:

    1: P0244: Turbocharger waste gate solenoid a range/performance(High Input)

     

    DTC 

    Brake control system 

    1: C0057 VDC control interruption because of engine instructions 

    2:  C0047 Improper CAN communication 

     

    Obviously I need to check and properly diagnose something to avoid P0244 again, but what exactly?

     

    im guessing the brake control system codes are the ECU’s reaction to the first code? 

    What causes jerking on / off acceleration?

    in General Vehicle Discussion

    My forester noticeably jerks when letting off the accelerator and when going back on, even when doing it extremely delicately. Coming off throttle, there's a short second then you feel like a surge / jerk. When applying throttle, it sort of jerks a bit heading back up the revs (rev gauge and move back and forward). Much more noticeable at lower speeds but still does it through the gears at higher speeds.

     

    Sometimes second gear, having a tiny but constant amount of throttle applies, the car will jerk back and forward kinda violently while sitting over 2k rpm.


    This was worse before I got it tuned, but it's still quite persistent. Reading up about could be a million things.. I've recently had spark plugs changed and the car scanned, which pulled no fault codes.

    It's not a biggy, just makes driving slightly unenjoyable.

     

    Thoughts on S-GT vs V6 WRX

    The weight of the newer cars is what holds them back from feeling fast. 
     

    even the STI needs a tune to feel fast. But the handling is a lot better and the parts aren’t generally worn out. 
     

    the 08-14 are the last of the cars without driver aids and radar crap so that’s a bonus. 
     

    the sg-t is very soft from what I remember. I drive one before trying the sti and that was it. But the sti was still pretty sad until I found a tuned one. 
     

    some slight lowering springs and a rear sway bar plus some wider rims with good tires and the sg-t is likely very nice and corner very well. 

    The DCCD diff does make it corner nicer if you open it up which the STI feature. 
     

    sg-t is probably easier to insure and really isn’t that attention grabbing. 

    Can vouch for the S-GT being easy to insure, owned one at 22 and it was basically no questions
    Lowering springs on it made a world of difference. Factory suspension is more 'i want to carry the kids around in comfort but also have 250hp' soft and floaty.

    I'd say the WRX is a much more 'raw' driving experience.

     

    It depends if you value extra's like safety, sophistication, brakes etc. as outlined above.

    I owned an S-GT a couple years back and they're still super fun wee cars that are just definitely held back by the crappy factory tune - so highly recommend getting it tuned properly if you end up buying one. 

     

    Also probably need to outline that the V6 will likely be going up in value too. 

    What have you done to your car today?

    Nice result!

    Apet by the looks of it? Nik's always been a good yarn there, really need to get my WRX finished and over to him...

    Speaking of, I'm one step closer now, finally got a new up pipe for the WRX, the old one had a cut in it from removing the heat shield, found a stainless steel one brand new on trademe for $80. So that should get me a step closer to running.
     

     

    Yup, sure is Apet. Nik is a super friendly, easy to deal with person.

    Buying the correct spark plug - help

    in General Vehicle Discussion

    Posted

    Hey all,

     

    Usually this would be a breeze with tracking the correct spark plugs for a Subaru.. but not to much the case with my Forester.

    It's a 2007 Subaru Forester SH5 2.0 XT, manual. It's registered as 2007 but technically a 2008+ model which seems to hiccup a few sites. The NGK, Repco & Supercheap sites haven't been much help, bar the Repco if I put my vehicle in as 2007, there's an EJ20 DOHC 16v Turbo to be selected but i'm not sure if this is pulling SG Forester parts. For all I know, they could use the same plug? it pulled an NGK PFR6B

     

    Anyway, trying to track some NGK iridiums. 

    2007 Subaru Forester XT 

    EJ20-COVERED

    SH5-002222

     

    Just being cautious before i accidentally blow money on the incorrect plug. Any help appreciated :)

    SH5 Catback Exhaust - Bought or Fabricated?

    Yeah, there's a very narrow rev range where it's not too bad but it's bonkers loud at idle and there are a few points in the range where it fairly roars.

     

    Latest round of mods is going to include a great big AdrenalinR resonator in the middle somewhere. The current one doesn't seem to do anything.

     

    Hmm yeah I'm definitely not about that super loud life. The AdrenalinR route seems a bit tricky to make up the parts, just from a 2 minute glance on their website anyway.. 

    SH5 Catback Exhaust - Bought or Fabricated?

    in General Vehicle Discussion

    I'm looking at getting a catback exhaust for my SH5 XT. Just want a bit more of that Subaru rumble to enjoy plus any small performance benefits that may come along with it.

    Redline performance offer a pretty easy purchase with the XFORCE variant here https://www.redlineperformance.co.nz/product/xforce-subaru-forester-xt-exhaust-kit-2009-12-wrx-grf-sedan/

     

    Is this of pretty reasonable value for a catback exhaust system? Or am I better off getting something custom made which could possibly save money & be of higher quality?

     

    I don't I'm wanting go turbo back route since $$ and noise

    Mechanic fitted standard WRX suspension into the SH5 for me.. very pleased with the results.

    Wheel nuts were on so tight that it stretched the thread on the studs on 3 corners. So a big f**k you to whoever did this originally. Luckily he found it then.. otherwise if I had to change a tyre, I would've been screwed.

     

    I also chucked on a GFB Respons BOV because.. I don't really know why. Pssshhh??

    SH5 Forester Lowering Options

    in Forester

    Posted

    Howdy Howdy

     

    MY SH5 XT Handles like a boat. It's a given really. Stock suspension made for carting the family around but i'm not about that life.

    Obviously my options are adjustable's (which i'm not wanting to fork out for) and lowering springs.. 

     

    But was also wondering if it's possible to lower an SH forester with say.. WRX suspension from the same era? Or anything else that anyone has had experience with?

    We had a non turbo SH and i owned a turbo SF5 that i did alot of work on to use on the track. 

     

    The SH5 is a boat, even more so at high speeds and old tired suspension. Get some decent tires lowering springs can help a bit but best would be coilicers or even is shocks tired and worn new shocks. Def do the rear sway bar. ITS SO TINY! front not too bad. The non turbo SH im not sure about the turbo ones have pretty weak rear difs too


    it’s absolutely a boat and I think that’s the first thing I need to address. Stupidly missed out on a full set of Pedders shocks and springs because the numpty selling them wouldn’t reply to my questions about shipping them.. should’ve just whacked but now!
