How many catalytic converters are on this car?

Just get a header of your choice, and the OpenFlash Tablet and call it a day. Come inspection, switch back. As long as you don't do anything stupid to get attention, they won't have a reason to pull you over.... maybe.

That was my worry, but there was one around the corner from my house. Literally 1/4 block away.

Just wondering if I get Ecutek tune, and go back to stock header if I had an aftermarket, would the tune itself be anything bad for smog? Besides probably break warranty..

most tunes will disable cat efficiency cel code and this will in general cause you to fail rediness test as none seem to force rediness.

Most tunes will also optimise fueling valve timing ignition timing ect for power and throttle response ect this often comes at the expense of emmissions.

If its a strict emmissions test where they check ecu readyness registers and check exhaust gasses then your going to need the stock tune or a carb approved tune in the car with all the stock cats to pass.

your tuner or you if you have the ecutek cable could flash it back to stock.

When smog checks do come around for me in the future, would it be a pain to re-tune/flash back to stock each time and costly? I mean they sell some superchargers and now a turbo that is CARB legal but come w/ a tune. I'd imagine if you go to smog with a kit like that since it's CARB it'd pass right? Or does getting the kit w/ tune fail it?

You can't. Most headers are catless and even the catted ones are NOT CARB legal. There is no way you can pass smog with any other header.

The only thing you can do for the exhaust while still being in compliance is a catback.

The tune itself is supposed to be CARB compliant, so you shouldn't have to reflash back to stock, IIRC.

Besides, I don't think an FI engine can run on a stock tune. I might be wrong, so the gurus can chime in if I am wrong on something.

I'm not 100% on all the different laws everywhere.

But i would imagine to be CARB legal the kit and tune would need to be fitted by an approved dealer and the CARB label attached and registered to car. The tune would be locked so it could not be changed/reflashed by owner.

contact a tuner that does CARB legal kits

Im not sure what tuners would charge to reflash car to stock tune maybe $50 it only takes a few minutes, car would have to be stock hardware wise though else it going to throw cels etc. and no you dont want to run an SC or turbo on a stock tune.

In california they seem to be super tough and any change to tune or exhaust cats etc is technically illegal.


The simplest way in CA is probably running stock car but tuned for E85 and having your own tuning device like Open Flash Tablet so you can flash your car back to stock tune yourself.

ie Fill car completely stock car with E85, Flash E85 tune with your tuning device.
Enjoy 20hp gain almost eliminate torque dip, smoother running.
come inspection time
Fill with petrol , flash your car back to stock with your tuning device, pass tests

Then return to E85

OFT cost $500 all up with tunes and tuning device, you can re flash as many times as you like, flashing takes 4 minutes.

I am getting a CARB legal SC for my car for this reason. If you buy a CARB legal SC or turbo you can install it yourself and you will pass smog. You have to run the supplied tune which is locked so you can't alter it (which would make it not CARB legal). These kits use the stock emissions equipment and you cannot change any of it out (header/front pipe). By can't I don't mean legally, I mean the supplied tune will simply not work without it.

[nova.86]

Do I have to run the supplied tune w/ the CARB Turbo kit? Or can I run an E85 tune w/ the kit, then convert to the CARB tune when it's time for smog? Would it be expensive to change since it wouldn't be OFT? And since the CARB tune would be locked and I'd be going back to E85 tune? Since I'd only smog the car once after all you know..I wouldn't mind re-tuning yearly, better than buying a non CARB FI kit and having to remove everything and place it back.

Most kits supply the CARB tune through ECUTEK and the cost of the ECUTEK license is included. Once you own the license it is free to reload into the car all you want, at least that's what the guys at delicious tuning told me. It's like marrying up the OFT to the car, same with the license (except you can't unmarry/divorce it). You will have to buy the E85 tune separately and I recommend you do it with ECUTEK for FI since you already have ECUTEK anyway (won't go into why because I am unwilling to debate this, just a personal recommendation). Once you have both tunes you can swap back and forth as much as you'd like. However, you can't just load up the CARB tune and go to do your SMOG check, many of your readiness tests will not have been completed yet and in California I believe you can only have one not completed. (Been a while for me) From reading the JRSC owners thread, I have seen it take up to 800 miles of driving on the CARB tune to get it ready, though that isn't very often. Mine readies up within 300 miles on the stock tune and it should be same on the CARB tune. If you have lots more questions feel free to PM me. I will either answer them or refer you to someone local to you than can help.

OFT dont do any CARB approved tunes


As long as you have an Ecutek Cable/dongle you can reflash ecutek tunes to your licienced ecu as many times as you like no cost.

The "lock" on the tune just means you cannot alter the tune itself ie change the tune parameters.
But you can flash over it with a new tune, then flash the original tune or carb tune as long as you have ECUTEK cable/dongle

My apologies if I was misleading in my post. This is correct. There are no CARB legal tunes with OFT as far as I am aware.

Thanks for the insight. I decided to go with the Afe catted uel header and magnaflow midpipe. Connecting to a Firebird/Camaro single 2.5" inlet/ 2.5" dual outlet freeflow Magnaflow muffler with 2.5/4.5 tips. Hopefully I don't get any cel's, I will just have to deal with it when it comes to that point. Looking into the tune as well.
