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.

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.

Either way you will need to run V-Power.

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.

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.
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 ******* about.
edit: This one looks ok.

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.
