hey i got a check engine light today. i installed my d/p thursday and i just got a check engine light on my way home from work today!!! what the heck is the check light all about? any guesses?

 

I'm gonna take a wild guess and say cat-ineffiency...What kind of DP did you get..

 

perrin performance

 

could it be an exhaust leak from the flange at the turbo or possibly the oxygen sensor not being tight enough?

 

i think you're gonna have to get the MIL fix.

 

HEY that's a common one...check out this website for their CEL fix...http://www.rallyperformance.com/scooby.shtml

These are the guys that are in the Sport Compact Car story and they sell Scooby Sports stuff (rally teams from UK use it).

They have a CEL fix somewhere in there with their DP and UP products.

 

Did you install a MIL eliminator? If not, I do believe the cel you are getting is CAT inefficiency.

Just do a search on MIL eliminator.

 

ditto, ditto, and DITTO on the MIL eliminator

If you reset your ECU, the CEL will probably go away for a while. I did that a couple of times, but it would always come back during a longer drive. Bought a mil eliminator and haven't had a problem since.

 

man you guys are the best! looking it up as we speak!

 

yea i have a pde downpipe and i have the same problem. i also have a helix cel fix but it doesn't seem to be doing it's job. gotta get it checked but had to fix the boost leak first. probs...can't live with em', can't avoid em'. good luck sakebomb.

 

pde d/p doesnt throw cels.

you probably have a leak big enough to alarm the ecu to throw the cel.

and IIRC 04 wrx's need a different type of "mil eliminator". different from 02/03 WRX's.

fix those leaks, and it should go away within a few start up's.

Justin are you sure that you have a PDE downpipe? If you're getting a CEL from a PDE downpipe that something is not right... Reason being is that the PDE downpipe is gaurenteed to have no CEL from it... The CEL you are probably getting is for your Up pipe which is normal.

I owned a PDE downpipe and unless you completely take off the rear 02 sensor off it's harness you CANNOT get a CEL.

i'm not too sure where it is from but i am getting it from somewhere. i was told that i had a pde up and down pipe from ragewrx who had the car b4 me. i guess i just gotta suck it up and have it looked at. where is a good place to have it checked? jon, i also installed the new T today and i ran it pretty hard tonight to see what i could peak and it hit 12.6. set=45 gain=15. hopefully i just need to tweek it a little. anyone have any ideas as to what set and gain i should try? thanx for any help.

Take it to a dealer and have them run the code.... cost u nothing. they will probably even blank it out for you.

It there anything else in combination with this that you previously had installed like a CAI or somthing?

we should also take a look at that area where he reconnected the hose you could also be having issues there. at those settings I am running at about 16PSI. what are you doing today... hopefully we can get together and I can look at it more thorally.
