gotta take the test soon. what are your experiences? what works and what doesnt work? i just have to take the obd2 plug in test. 02' wrx. boost controller downpipe.

thanks

 

Which are you using right now? Are you just driving with a CEL on?

I would say go for the electrical fix if they're just going to check for CELs. Then I would say by an EM system so you don't have to worry about it and it will get you better power than your current set up.

 

yes, im just driving around with the CEL on. p0420 code because of the downpipe. will the resistor work for the "readiness" codes? i heard sometimes it doesnt work. i dont want to get an engine management setup cuz im sellin the scooby wagon soon. just wanna get this test over with. thanks for the input. your help is greatly appreciated.

 

Good question, I don't have a definitive answer for you on that one right now. Sorry.

 

I had my spacer on for almost 6 months with no codes. Then I got my AP so it wasn't necessary anymore. But, it's still there. I would go with the spacer. It's just a simple solution.

 

Just run the spacer so the o2 reads normal, besides it's only around $7 at any parts store.
