    new purchase and new problems help'''

    hi i recently bought a 2002 wrx wagon and i just got a cel , 2 hours after purchase with no warranty , here are the codes po301,po302,po303,po304 , with are misfires all 4 cyln, and i also have a code po244 with it said wastegate sel A range performance, i only know whats on the vehicle by looks , it has a full cobb exhaust and a racing downpipe the one right off the turbo , and it has a hallman pro mbc, and a mishimoto rad. now i do get alot of rough idle but seems to clear up alittle but has soom serious falling off and sputter while boosting , i do not know where the mbc is set due to no boost gauge. what should i do first , to try to eliminate the problems , could the mbc be set to high causing all these codes or plugs ? please help, thanks

    I'd get a compression test on all cylinders to make sure the block isn't effed up. Then go from there...do you know if it's tuned???

    The wastegate code is for sure overboosting. You MUST remove the MBC or get a tune that utilizes it properly. Even without the MBC you have to make wure you are running a map that supports your other mods (stage II, intake must match, etc.). Most people willing to plunk down the cash for a full Cobb exhaust are running an AP, however an MBC requires a custom map not an OTS Cobb stage II map. It is a good chance that the AP was unmarried and sold, in which case you are on a stock map which not acceptable with your mods. - otherwise your ECU is locked out if you don't have the AP that was installed! This possibility, along with the fact that they dropped the V1 and nearly left me with a $600 paperweight, is why I no longer support them.

    I would recommend a tactrix cable so you can see how the car is tuned, but it won't work if they locked you out and I think you have to send them your ECU to sort it.

    The software is free - opensource.

    Actually they have a new ultra cheap version of the cable out that is advertised to work on the old models (like ours). I would search for some reviews, and if it isn't clearly going to work then get the real tactrix cable. You don't really need the new 2.0 canbus version but it isn't much more than a 1.3u anyway and causes the least issues.

    You will at least be able to log, and if you're lucky and it isn't locked out you will be able to access the map. I would remove the MBC, get the cable, try to read the map, run learning view, and log the car. If you can read the map, post it, otherwise post the learning view and the logs (upload to google docs as a spreadsheet). It isn't as complicated as it sounds, and you shouldn't drive the car hard at all until you do ALL of these things.

    Not sure about this one, you might have to use an old version of ECU flash or muddle around so research it first:
    BFM Subaru Impreza WRX STI Legacy Tactrix 1.3 OBD2 Flash Cable ECU Tuner CHIP | eBay

    This is GTG (you need the '02 reflash connector for later):
    Tactrix Openport 2.0

    They also have ECU service now I see - if you are locked out contact them and see if they can fix it:
    ECU Flash Recovery

    Time to read up - it is your only hope when getting a previously modified car to sort out.

    You are still overboosting. The stock boost control system needs to be all put back together correctly with stock diameter tubing, restrictor pill, & T. and you need a standard stage II map (which can be had for free).

    You still need to find out what map is on there and fix it or get a map that is correct, so you still need to do what I said above. You just have to know and it is really the only place to start. If it is a map that is actually designed to run the MBC then I think the boost control mapping will be unsuitable for the stock boost control system and lead to the continued overboosting. If we can ascertain whether it is a good map for an MBC you can put it back on and set it correctly from the logs. IMO a boost gauge is required for that setup though.

    I doubt the car is tuned. FYI-Don't buy a modded car unless you know what your getting into. The problem is the TBE and no tune in the colder weather. Also that BFM cable does not reflash 02-03 WRX's.

    But did you get a tune (or at least a stage 2 map?) on your 04?

    Something is up with it overboosting...comes down to something in the boost system whether it's the MBC being incorrectly set, not having the stock BCS, missing a restrictor pill, COLD WEATHER, not tuned, wastegate actuator stuck?, etc...

    hey mike,
    as far as the 04 no never tuned it and it was all turbo xs stuff , not like it really matters but no mapping and no codes,,,

    now here is what i did today , first off i started out with a cel code po244 , then i went to subie dealer and bought all new vac lines restrictor pill and reset the computer again ,
    big change in the car smoother and better turbo response no sputtering at higher rpms. although i got a cel light again so i just took it up to advanced to read the code again and now the po244 is not there but my #2 and #4 cly are misfiring ... so now what should i do , i already checked the plugs and they look to be new and not carboned or fueled up.
