    you need to bore out the wastegate hole in the primary turbo . the hole is like 13 mm but the flap is like 23 . i took mine out to 19 ish and it will run 7 psi stable as ( if on wastegate only )

    /quote]

    After doing these tests and seeing how much the ECU uses the ECV during primary turbo mode. I\'m guessing porting the primary Waste Gate alone could have a negative effect on the ECV/ECU.

    Since altering the ECV duty cycle I have no boost spikes now, running the same boost.

    Edit: De-catting my Primary (altering waste gate duty cycle) I got spikes because I didn\'t change my ECV duty cycle to match. Every time I boost spiked on primary previously, I was tripping the Differential Pressure Sensor, also making my Zerosports Controller have a relay seizure.

    Now that I\'ve altered my ECV duty cycle to match my Primary Waste Gates Duty Cycle, I have no boost spikes/CEL\'s running the same boost as before

    When the ECU (monitoring Differential Pressure Sensor and MAP) sees that the Primary Waste Gate isn\'t keeping up or it\'s over working, the ECU opens the ECV to control exhaust flow from the Primary.

    ECV Stabilizes the Primary Boost Levels.

    I haven\'t touched my GFB Bleed at all, but now my Primary Boost is higher, stronger, more stable and spools faster.

    When you say you \'altered your ECV duty cycle\', im guessing you are talking about an ECU tweak? (Thinking about trying the .8mm hose 1 mod in my RevD)

    Interesting re: ECV stabilises primary boost comment. I\'ve noticed that running slightly higher boost levels (.8 bar target) with my EBC controlling wastegate, there is massive lag between gears if im pushing hard. If i run lower boost level, secondary doesnt reach full potential but spool up is quicker between gears (strangely enough) - any thoughts? Could be something totally unrelated...but am thinking about going back to stock boost control and troubleshooting properly 😎

    Just some help, Going to sell the Misses 2001 20n but it needs a new O2/AFR sensor (the one plugged into the extractors)

    Do I buy 2nd hand or new? and if new, is it a case of just biting the bullet with the expensive Subaru one? or is there a cheaper universal one that will work just as well, heard stories about some universals working and other not.

    Thanks in advance

    BE/BH replacement inlet hose for TT?

    in Legacy & Outback

    Posted

    BE Rev-D with HKS boost controller (non sequential). Looking to return it to stock with a 0.8mm restrictor pill as I want to re-use factory boost controller for better tuning results later on ; you alluded to the tuneable ECU: Id agree - much prefer to have ECU- table control of boost/ign timing so you can precisely map rather than just cranking it up with a non sequential/boost tap and watching a piston fly out the side....(not to mention our fuel here in the land of the \'engine failure induced\' long white cloud)

    I like the idea of porting WG too - wouldn\'t hurt to smooth some of the casting flaws and tease out the opening...

    Did some reading - anyone had any luck with ECU editing - specifically romraider and disabling rear o2 sensor CEL?

    It also starts much easier, has no pinging at all now, I can hear the primary downpipe thumping away from drivers seat and exhaust tone is much deeper/louder even with stock muffler and the induction noise sounds wicked (bit like an industrial vacuum cleaner under the bonnet).

    Edit: CEL went straight out but Logged:

    CEL 13-camshaft sensor (no surprises there)

    CEL 65-differential pressure sensor

    Hey man, thinking of deleting Cat - any issues with CEL for rear O2 on a stock-ish B4? I \'ve heard you can inhibit the CEL with the right software..

    Was it stalling before you put bov on? Did you do an ECU reset? Any changes to BOV plumbing from factory routing?

    Recirc air a common discussion point - but if your throttle is closed, where the air goes probably doesn\'t make all that much difference pre-throttle body off boost...in my humble opinion

    Apples and oranges - take what you want from it- had to tweak my idle up using laptop and OBD2 VagCom cable with "FreeSSM" software after doing \'hose10\' mod on my \'01 JDM B4to prevent stalling.

    Short story, factory plumbing has a controlled vacuum bleed that helps prevent Boost spikes/surge by \'leaking\' some boost back to inlet via bypass. ECU tuned to expect this so, short of tuning with expensive Tactrix cable, I just bumped the idle up 100rpm (once I eliminated the factory bleed, the idle dropped around 100RPM causing stalling/low idle exactly as you explained) with cheap ebay cable and runs fine. Only catch is that if you remove battery, you have to do it again.

    So after all that, I took it in to subtech and also petermark autos for them to have a listen, and they said its not a bearing. Rekon its just cam overlap or wear, so nothing major to worry about. So not sure how Winger diagnosed signs of big end wear when two other subaru specialists said they cant hear anything.

    Don\'t ya hate that? Always makes you wonder if they\'re genuinely helpful or just trying to score the job...

    Did a first service on my WRX since i\'ve owned it(since september) Pretty sure the lady who had it before me only put water in the radiator and also BOTH radiator fans were unplugged so whoever did the cambelt on it last obviously forgot to plug them back in. Wondered why the temp would sky rocket on a hot day :\'( However now its running all good now

    Decided to go with the Penrite 10w-50 in the end. Asked a few Subaru mechanics and specialists and they said it would be all good. What do you all use?

    Check out the old Air Filter though! Its like king kong farted into it

    Now she is running alot nicer since the service and it is definitely MUCH better with a new air filter.

    /quote]

    I use the same oil - seems to work fine for me - stable oil pressures even on a warm day. Might just be me but do notice a little more valve train noise just off idle but goes away as quickly as it starts as rpm builds could be my stupid clutch tho - anyone else noticed anything (150k B4 engine?

    Not trying to dig up old threads about consumer products or anything but I was warned off any after market oil filters due to primary turbo \'limitations\' on the twins: opinions?

    You know that aftermarket filters are manufactured to meet or exceed OE spec right? So if you are using an equivalent filter rather than the wrong one you will have no problems unless it fails.

    Yeah I know they do exceed OE spec - was more interested to hear from others whether there have been any horror stories of failure attributed to any particular brand (to steer away from). Obviously, filters are fairly low cost items and you wouldn\'t go buying crap from ebay or anything - just curious to see whether Subaru made filters flow any better than your regular Repco/Supercheap items or if you\'re essentially just paying for branding

    How much current do you need? 50mm does seem very big...

    url]http://www.engineeringtoolbox.com/amps-wire-gauge-d_730.html[/url]

    50mm is huge !

    maybe a decimal point got lost in translation...

    ;D

    I usually factor 250A per 50mm run when doing big, dumb s*** with 12V electrics.

    A starter will typically pull about 200A. Ideally you want 50mm (0ga) but 35mm (2ga) is fine as you\'re unlikely to crank for more than about 5 seconds.

    As for voltage drop, the resistance of a properly terminated (hydro crimped copper lugs) 50mm cable is measured in ohms per kilometre - about 0.322 of them - so 250A over 5m will give you a drop of 0.403v - which is actually not ideal, as you\'re losing approximately 100w of energy in heat throughout the length of the cable.

    Just to put the fear of god in you, if you get a short 1 metre into the cable, and you\'re running a 0.5 metre long ground wire with a 700CCA battery,

    the cable will be attempting to dissipate almost 9kw of heat and you will have a burning car real fast if you don\'t have a fuse.

    Either that or your new impromptu 700A/12V arc welder will rapidly punch a hole in whatever it\'s touching.

    Is a cable an Ohmic conductor? Lol

    Hehehe was just gonna throw my 2 cents in but you hit it on the head. Always funny when different levels of electrical knowledge clash....

    Had a look under the hood after noticing some wisps of smoke coming from scoop when engine off- developed an oil leak somewhere near the primary....looks like its under the heatshield - any guesses?

    Jacked up one side (was only jacking front but rear wheel came up too- awesome stiff construction!) and found i have cracked cv boot spraying grease on cat

    **Edit** - Drove up to Richard (SAS) and had new boot fitted in about 10 mins - cheers dude!

    ok so yes it\'ll over flow just thought I\'d get these 550cc ones for $100 and just safe guard my car from running out of gas. I just assumed what wasn\'t used would just be sent back to the tank

    /quote]

    The extra fuel won\'t go back to the tank. It\'ll all go into the cylinders. All 25% extra of it. Mine spat awesome flames on overrun when I did it :)

    (I.e. don\'t do it......)

    Im thinking ECU to injector pulse width is based on original injector sizing - will o2 sensor feedback loop correct this at all? (Rich signal sent to ECU to lean off by reducing injector pulse width?) im guessing open loop fuelling will be screwed as explained :)

    Is that the one you can hook up with the torque app? What sort of data do you get from it?

    I have the Torque app and a bluetooth OBD11 plug, Have not used it on a subaru but on the few hiace vans and a sprinter I have used it on pretty much any info you want/need is available.

    if it has a sensor for it then it should be able to read the data,

    on my driving screen I usually have boost,common rail pressure,speed ( gps and speed sensor) intake air temp,oil temp,oil pressure and water temp,

    I have Engine link HD and an iPad - works for OBD2 standard PID\'s. Subaru-specific SSM doesn\'t like the wifi (and/or Bluetooth) ELM 327 dongles - something to do with the data transmission encoding. You can pull CEL codes off though - for more detailed data, use an EBAY Vag-Com cable $20 from hong kong with learning view/laptop or Romraider software to read sensor data or read/write ECU with more expensive tactrix cable
