Air Intake Dilema
O.K, Installed the Hurricane air carbon fiber air intake. 30 minute job took me 6 hours to get it right...LOL! It looks great.
Now, the yellow engine light (outline of engine) stays on. Took it to the dealer and they said it's cause the intake is making the vette run richer or leaner. They said they could reset it but, it would just come on again before I left the dealership.
HELP.
Everyone that has modded their air intake can't be looking at this obnoxious light all the time.
How do I fix that and still have the light work when it's actually needed?
Thanks in advance.

Other then that, there was nothing else it hook up.
Dealer said all the additional air flow causes this and they see it all the time with aftermarket intakes or K&N type filters.

You shouldn't get any codes from an air intake. The air sensor you hooked up might be in backwards. It goes in a specific way for air flow direction. Flip it around and see if you still get the code. In general your car was probably running rich from the factory. A CAI will only make it run a little leaner, which it probably needs anyway. You should not be having this problem if everything is hooked up right. Don't you just love to hear that stuff. Good luck.

The only thing to hook up was the thing on the side of the air intake (MAF?) and that just snapped in. Does it matter which side is up? Cause I noticed you can install it either way.

You see, these cars are programmed from the factory to run based on parameters, once you go beyond that given parameter then you what see on your dash....SES light.
Now, with tuning, those SES lights can be a thing of the past because through tuining, you can adjust the parameter to compensate for your mods.
You have many tuning options nowadays, the option below is yet another venue you can take to obtain more control of your car.
This is not a cookie cutter tune, this tune will be tailor made for you. Adjustments are unlimited...if you add more mods, changes can be made for free!
Thanks,

Yes, it is possible that you are running a little leaner now due to the increased airflow.

This is on a LS3, correct? The MAF can be installed backwards. If you look closely on the end where the connector is the is a little arrow. It must point in the direction of air flow, ie towards the engine.
If that is correct, then unplug your battery negative terminal for 30mins or so to reset your fuel trims back to 0. Then hook the battery back up and try agan. Let it idle for a few minutes to relearn.

The best tuning device you have is the ECM already installed in your car. It can easily adjust to any changes in airflow increases from a CAI. Per the previous threads, I would check to make sure the MAF is installed correctly, all connections are tight, and there are no vacuum leaks behind the MAF. A leak behind the MAF will definitely result in a lean condition, from the un-metered additional air.
BTW, you should not need to disconnect the battery to reset your fuel trims, just pull the ECM fuse for 30 seconds or so, replace.

I don't know how the MAF secures to a Hurricane, but if you are using the original screw locations, I don't think it can be installed backwards. There are others with LS3s and aftermarket CAIs that have had the same issue. If the ECM is calling for more gas due to increased flow beyond the factory parameters, you will throw the 171 and 174 codes. After trying everything with my Vortex Rammer to eliminate those codes, I decided tuning was the only way to go. BTW - since I decided to tune, I also decided to add headers, a 160 T-stat and 4.10s. Be careful.... LOL

Most likely a air leak at a connection... tune should not be necessary with intake..

I realize with your unit you can flash back to stock but can they still see it was flashed and document that it was not done by an authorized person therefor voiding my warranty?
I have been waiting for something like your unit for a while. At one point EFI was gonna have one called autocal but I have not seen it yet.

I agree with you but now a days with GM being really careful about what they warranty I am concerned tuning my Z06 could void my warranty. The little performance edge is not worth that.

I know how you feel Joe. GM and many other manufactures have been doing this "don't mess with your car" or else deal for years. Become friends with the servive guys and manager; you'll be shock to see what they would do for you. Just talk to them and treat them like people and you be all good.
In terms of performance gains...its a lot more than a little edge my friend, especially in your Z. Dyno your stock Z and see how rich and how little timing it has and how aggressive the TM and the timing retard based on AIT and ECT is

I agree. I should also add after checking all this, drive your car for a few hundred miles to let the ECM "learn". The CEL could very well go away after this period.

I took your advice and disconnected the battery, had dinner, and then reconnected it and viola' the light is out now.
Thanks for all the advice, you guys are great!

If it reappears, then just drive it as is for a few hundred miles. Keep us in touch. Good luck.
