which is best?
hi, i have a my95 wrx and a set of equal length headers on it, should i keep them on with the mines chip or go back to standard wrx? thanks

What are you looking for?? |
i was told mines chip runs with 100ron and not to use the headers i got on? is this right.
|
mines is a jap ecu and tend to have rather agressive maps with lots of advance for 100ron fuel. have you been driving the car a long time like this? the importer might have sorted the ecu for uk SUL.
|
driving it for about 1 to 2 mths now with the new headers on, not sure on the importer as its been over here for a while. dont know what to do!!! because with the new headers i cant fit the o2 sensor as it fouls on the block might take them off and go back to olds for now till i know what i want to do. any help with mods will be great.
|
Are you saying that, you are running with NO lambda??
|
yes i am...running without one....:( just let me down gentle what have i been doing running without one?

I advise you get the lambda refitted ASAP, have you not got a boss in the downpipe you can fit it in? Remove the COF sensor in the downpipe and fit the lambda in there if nessisary. Or replace the headers with OE as you said earlier. Either way, you will need it fitting for a MOT emission pass. |
u will need this fitted for it to pass the MOT on the emissions.
|
the machine was broken on the day...lol

can i fit this in as long as mine has the 4 block on the ecu? http://cgi.ebay.co.uk/ws/eBayISAPI.d...=STRK:MEWAX:IT

Hi mate, this is what i have in mine already i just need to stop it juddering over 0.5..reset the ecu and it goes like a train, but then the c/e comes on and down it goes....http://i389.photobucket.com/albums/o...9092010294.jpg

Get the lambda refitted and see what happens. |
lambda fault does not show.....22/24/33 where is the vss2 ive had a look but cant seem to find it, there is nothing on the speedo cable wire wise anyway any ideas.

22 is knock sensor, replace it. 24 is iacs 33 is vss2 These two can be related. Sort the vss2 first, i'm 99% sure it's the speedo end, as opposed to the gearbox end. This can cause the ECU to think the iacs is not operating properly. |
nice one mate, iam going back to my old headers for now untill i get a new hole done for the sensor on the up pipe of the equal length ones. i will keep you updated.thanks
|
GC8C48D any info on this model? is this right that its the 260bhp one?

The boss is on the bottom pipe just where it joins the up pipe. job for tonight.

Was you looking at a different location before?? As it is not possible for the lambda to foul on the block when installed in the header. |
sorry...on my new headers and down pipe the lambda sensor fouls on the block.on my old headers and up pipe the lambda is on the bottom pipe which is fine.
|
hi, old headers are back on and i like the sound of the rumble, anyway lambda is back on reset the ecu 5 mile down the road the c/e light come back on same 3 faults 22/24/33....but it is going over .5 without the juddering so at least that has gone. has anyone got a spare knock sensor i can try? and what can i do about the iacv can i clean it or is it a new one....vss2 have not got a clue about that one yet need to find the wiring path from the ecu.
|
I repeat.

This can cause the ECU to think the iacs is not operating properly. You can get a used KS, in the 'For Sale' on here or Ebay, make sure you get the right one for your MY(Subaru Part No: 22060AA030 22060AA031) . A faulty KS will cause the ECU to pull the timing and reduce performance. VSS2 will probably mean removing the binnicle and checking the cable and the connections behind. Leave the IACS till last as that may be being caused by the VSS2.;) Come on, pull your finger out and stop fcuking about.:lol1: edit: This one looks ok. |
will do mate.......

hi, right changed the knock sensor and reset the ecu all good for about 4/5 miles then the cel came back on and have the same 3 codes....so i might take out the cel blub.....only joking.as for the vss2 my clocks are cable driven what else can i look for on this fault. thanks

Did you follow the correct reset procedure?? Change the IACS now, as i said earlier, this will cause a VSS due to the IACS not telling the ECU the car is at idle. So the ECU is expecting a signal from the VSS but because you are at idle it doesn't get one and therefor thinks the VSS is at fault. |
what do i clean in this IACV.........http://i389.photobucket.com/albums/o...9122010421.jpg thanks
|
Just drown it in carb cleaner or petrol and watch the sh1te pour out.;)
A small brush is also handy. |
