my car throws a cel after 80 mph on the highway i have no cats is that the problem?

 

Just after 80mph? Or at certain throttle positions? More info needed, mods, etc.

Do you have a P0420 eliminator for having no cats? Do you know what code it is?

Oh and nice thread title

 

Yeah, in the future you may want to put something about your problem in the subject title...maybe something like "CEL light at 80+ mph"...i think something of that sort would get you man more responses...good luck

 

Your thread title sucks! ><
Take it to the dealer and make use of your wonderful warranty! Oh wait you have no cats.... try this: slap the stock turboback back on, see if you still get the same issues. If you do, then take it to your dealer. Or if you have a Subaru-fluent mechanic, take it to him with your current set-up.

 

hopefully whoever put your DP on soldered your CEL fix decent...if you didnt get a CEL fix w/your DP then thats probably why its throwing a cell. you shouldnt throw a CEL with just the uppipe cat gone, so do what Choku Dori said and put that stock DP back on and drive it for a few days, if the CEL stays off, you've found your problemo.

 

Dude long time no see!!.. Is this the same cel that you wanted me to check b4 your car got shipped?? Take your self to an auto parts store like checkers or some thing like it and ask them if you can borrow an OBD-II scanner and pull the code. Don't go back to stock and waste all that time w/ something i'm pretty sure could be so simple to fix. So where are you now cali right?? LMK talk to you l8tr, Mario :banana:

 

thanks for the help everyone here's the deal i just put on my vf-30 and before that i had no problems . anytime i'm crusing above 70 near 80 the cel comes on and i can't figure this out i even checked my sbc id boost controler but to no avail so any more suggestions would be appreciated and mario i'm at camp pendleton near oceanside

 

Cool, good to here from ya. How much boost are you running you might want to to turn it down. I put my PnP VF30 in w/ the Delta dash running my injectors where at 101% duty cycle at 14.5 psi.
Turn that shiz nit down and see what happens

 

Do you have a CEL fix for being catless, wired to the rear O2 sensor?

 

no cel fix until i put the vf-30 on it never had a cel
