ECU' s and check engine lights
hey..... just quick question
I have recently put on an HKS Carbon Ti With Vishnue up pipe and divorced down pipe. The problem i seem to be getting in that my check engine light won't go away.
I've been recommended to get an o2 simulator or new ECU
Will those work? I need your opinoins ...
thanks a lot ...

I am fairly new to the WRX world but from what I've read so far, the CEL is probably caused by the up or down pipe, or both.
As far as I know there are readily available fixes for this. One is a resistor mod that I don't know a lot about. You shouldn't need to replace your ECU.
Try a search on "resistor mod" or something.

The CEL you are getting is most likely the o2 sensor code, because the catalytic converters are not there in the downpipe. You're reading a higher exhaust gas temperature therefore throwing the CEL. You can get a resistor fix or get a mechanical fix where you just have this bolt looking thing and you screw that into the bung where the o2 sensor goes and then you screw in the o2 sensor. This works also, if you would like one made, I can make you one for a good price. pm me you're interested.

Did you meen the EGT sensor? How can an O2 sensor read temperature? Or is one sensor in the Up Pipe (O2 for example) and the other one (EGT) in the DP?
