    few random modding questions

    TUNING - i like all the features in the ap but open source just seems much more worth the money not to mention its half the price. so heres a few questions about open source:
    --- can you scan codes,view things such as boost,far, and so on
    --- can you set a launch control
    --- can you see your 0-60 and 1/4 times?

    BOOST CONTROL - i know that when using an electronic boost control solenoid you must tune the car but when it comes to a manual boost controller do you need to tune?

    WASTE GATE - what are the benefits of a EWG? and what would something like the kit that cobb offers with the up pipe package show in gains? and this does require a tune correct?
    --- External Wastegate Uppipe Kit with TiAL 44mm WG

    BYPASS VALVE - when should this be upgraded (not with a BOV i know)

    BRAKES - are they really that bad every review i read involving them everyone is bashing them

    TURBO INLET HOSE - does one such as the perrin require a tune not much to read on them? at what point does the stock one become restrictive? and will this be ok to use at the lower stages (1-2 maybe 3)

    HOSES - will radiator and intercooler hoses be of benefit and do the intercooler hoses need a tune (maybe because they will flow more air?)

    FUEL INJECTORS - on the new wrx just want to clarify if they are top or side feed

    MAF/MAP - what are the differences and benefits of mass air flow and mass air pressure sensors?

    sorry for so many questions but really like to know everything in details and never had a turbo car (actually never even a 4 cylinder or even foreign O_o )
    thanks to anyone who takes time to help me out

    -You can log parameters. You can't directly see check engine codes without some other software, however.
    -You can get a patch that will allow launch control and flat foot shifting. You'll have to look up tinywrx patches. I have one. It does as advertised.
    -No. I wouldn't trust the Cobb APs 0-60 or 1/4 times anyhow, however.

    BOOST CONTROL - i know that when using an electronic boost control solenoid you must tune the car but when it comes to a manual boost controller do you need to tune?
    Boost is just one piece of the puzzle. While you can alter the boost pressure by using a MBC without any form of ECU tuning, you should be taking timing & fueling into account as well. To clarify, I would not advise raising the boost on the car with just a MBC and no engine management.

    WASTE GATE - what are the benefits of a EWG? and what would something like the kit that cobb offers with the up pipe package show in gains? and this does require a tune correct?
    --- External Wastegate Uppipe Kit with TiAL 44mm WG

    BYPASS VALVE - when should this be upgraded (not with a BOV i know)
    If yours is leaking. What year/model car do you have? Normally they are okay until you are pushing pretty high boost levels.

    BRAKES - are they really that bad every review i read involving them everyone is bashing them
    Depends on what you are doing. If you are on a road course, you'll fade the stock STi pads in probably a lap or two. If you are driving like a normal person and not stopping 70-20mph multiple times back to back... you should be okay. I personally am a huge fan of brake upgrades though - the feel you gain from them is nice. Some stainless lines and better pads are relatively cheap and will make a great change in pedal feel if you properly bleed the system.

    TURBO INLET HOSE - does one such as the perrin require a tune not much to read on them? at what point does the stock one become restrictive? and will this be ok to use at the lower stages (1-2 maybe 3)
    Normally in the older models, people replace them if they get ripped or just to be safe. In the newer STi's (which use a different intake system anyhow) some tuners seem to be pushing aftermarket turbo inlets surprisingly.

    HOSES - will radiator and intercooler hoses be of benefit and do the intercooler hoses need a tune (maybe because they will flow more air?)
    No benefit. A hose is a hose in that sense... unless it is a broken hose. Most people who upgrade them upgrade them for aesthetic reasons.

    On a related note, however, you may look into picking up some nice T-bolt clamps in place of some of the worm clamps that hold your rubber/silicone boost hoses together. The worm clamps have been known to break, loosen up, or tear apart softer rubber. Just make sure you get the right size T-bolt clamps, as they have a much more narrow tolerance of pipe sizes.

    FUEL INJECTORS - on the new wrx just want to clarify if they are top or side feed
    Unabomber's thoughts on the matter

    MAF/MAP - what are the differences and benefits of mass air flow and mass air pressure sensors?
    You just said it... Sort of.
    MAF -> Mass Air Flow sensor -> senses the mass of air flowing at the sensor. Basically a heated wire that is forced to a constant temperature. The more mass of air that flows by it... the more current is required to hold temp.
    MAP -> Manifold Absolute Pressure sensor -> measures absolute air pressure inside the manifold. This is commonly known as boost pressure when you convert it to MRP (manifold relative pressure) by subtracting atmospheric pressure from MAP.

    sorry for so many questions but really like to know everything in details and never had a turbo car (actually never even a 4 cylinder or even foreign O_o )

    No problem. Check out Unabomber's Manifesto over on NASIOC if you are looking for a nice overview of stuff. Google is always a good friend

    Just take your time and do your reading. Good to hear though =)

    On injectors? Yup. To my understanding at least.

    Your questions are all over the place bud. You gotta do some reading and slow down a bit. Your car isn't in and you are asking about upgrading the injectors (without even knowing the stock size or orientation) for some reason.

    Why would you want to convert to side feed injectors?

    I don't believe people run EcuFlash or RomRaider on a mac. I could be wrong.

    Side feed injectors were only used in 04-06 STIs (and LGTs)...why on earth would you care about those?

    Side feed injector options suck, most people with sidefeed (04-06 STi) eventually end up converting to top feed. I have no idea why anyone that already has top feed injectors would ever want to convert to side feed.
