Check engine light came on after I installed my short ram intake and it diagnosed as "too much air flow" into the engine...is this bad? The car noticebly pulls harder especially in 3rd gear on the highway (very impressive) but I don't wanna mess anything up...thanks for the input...

 

Some people say you should reset your ECU after doing any performance mods. I don't know how to do this, but I think it's something to do with disconnecting battery terminals and what not. Get your radio codes handy.

 

I'm not sure if you need to reprogram the radio if you reset by pulling the no. 25, 7.5 amp (in cabin not under the hood) "backup" fuse for about 60 seconds. I did it once on MY 03 and I made a note to myself:

A/C settings are Reset.
Stereo and Clock did not Reset.

By A/C settings I mean it turns off this:

To deactivate automatic a/c feature on a 2002+ S2000:

1) Turn the ignition switch "on," but dont start the car.
2) Turn fan speed off.
3) Turn temperature knob all the way to the left (blue area).
4) Turn vent knob to all the way to the left (panel position).
5) Turn the ignitions switch "off."
6) Hold down both air recirculation button and a/c button while turning the ignition switch "on." Nothing lights up initially, keep waiting. The orange air recirculation indicator on the button will start flashing.
7) Continue holding both buttons until the orange air recirculation indicator stops flashing, then let go.

It never does hurt to have those radio codes handy though. I hope you wrote down the actual DTC/CEL code, or will before you clear it. Good Luck
BTW. I probably would have reset my ECU had I installed such a mod. Since you did not and the DTC you have seems to directly relate to your intake, I would reset the ECU once and see if the DTC/CEL returns. Also it is my understanding that clearing a DTC/CEL with an OBDII scanner is not the same as actually resetting the ECU. What I'm talking about here is reseting the ECU via pulling the no.25 "backup" fuse. Good Luck again

 

You most likely routed the hoses wrong.

 

This is a common mistake when installing a CAI.
BTW, that code is P0411 -- Secondary Air Injection System Incorrect Air Flow.

It has nothing to do with "too much air flow into the engine". You misinterpretted it.

Check out your hose routing and white check valve direction as per:

For those who are telling people to reset the ECU by disconnecting the battery and "get your radio code handy", please stop doing this. It is NOT necessary to disconnect the battery to reset the ECU. All you have to do is pull the "BACK UP" fuse for a few seconds. This will do the job nicely AND maintain the radio operation without needing the code.

 

Nice flashlight, 6p? Do I see shin-etsu on the tailcap switch, or is that just the lighting?

According to Nimbus in another thread this might be the only known option for MY 06 owners, at least for now. Savages! The no.25 backup fuse ECU reset does not work on the MY 06 ECU according to Nimbus. Also if one were to attempt such savagery they would be well advised to wait a good 20-25 minutes after turning the car off. The reasoning is that supposedly the MY 06 ECU does not like to be disconnected for 15 minutes after the car is turned off. I imagine it wouldn't take to kindly to having it's power taken away during whatever the hell it's doing for those 15 min either. Again I have no idea is this will even reset a MY 06 ECU, I'm just ranting again.

I thought I saw some white guk around the edge of the rubber push button switch. I thought it might be silicone grease as preservative. "wino blinder" that's funny. Must be, I have never seen the high output lamp, can only imagine.

I agree the battery disconnect reset is a bad idea. Assuming it's true the MY 06 ECU dosen't like to be disconnected for 15 minutes after shutdown, there is no logic to what I was thinking about not disconnecting the battery for 15-20 min either? I swear I read that the MY 06 ECU should not be disconnected for 15 min after shutoff. Maybe I'm mistaken there, wouldn't be the first time eh?
