I wondered if just having the CEL mapped out would be alot cheaper than a full remap or whether the license fee would make it unviable?

We replaced our exhaust with a full decat which obviously threw on the light. Its a 2004 WRX.

 

I took my wrx to the dealership recently when after I fitted my decat system recently. Cost 0 to clear the light

 

I guess you could map it out with the likes of ecuexplorer with out any license costs. But as youve de-catted it you may as well have it mapped and use the gains from the decat

 

Unfortunately, the car is up for sale but having to explain the CEL might put the fear of god into someone who doesnt understand or believe the real reason.

 

just resetting it is different to what the OP is after and the CEL will return again.

will they not wonder why it isn't mapped for the exhaust also

Got my resistorin to solvethat problem

 

sorted

 

plug the original back on and sell the decat separate

 

Maybe, i could easily advise a remap because of the exhaust but that is less problematic than having to fully explain a lit CEL. Obviously to the educated a CEL on due to a decat is normal but to the uneducated it could cause doubt about the car/engine when there is no need.

Anyway, back to the original question, is it viable or more cost effective to map out JUST the CEL?

 

The problem is that if you went to see the car would you believe that the CEL is on due to decat? Or would you possibly think maybe there is something else wrong with the engine.
I would advise getting someone with a code reader to blank out the light and stick a resister in place of the connection cable.
I would also advise the potential owner that a remap is needed......this saves you dealing with hassle when the new owner comes back saying " the engine went bang" after a week of hammering their new toy

 

I didnt think the resistor trick worked for turbo back decats and i didnt think running a WRX with a decat was an issue, unlike STI's?

 

Do the job properly or put the original exhaust back on.
