Hello.

I just installed my FRPP CAI (85mm) and tuned my stang
to 93 octane tune with SCT2 from Brenspeed.

The result?
WOW!
I had to change my driving habit to launch the car without spning rear.
(It didn't do unless I really floored it)
I totally love this!!

Now, I've driven it about 40miles and sudden;y I got code.
P0175
SCT2 read it as "System too rich"
IT is too late to call Brenspeed, and it is dark and thunderstorming out side.
I'll check CAI installation tommorow.

But would it be serious prob?
I know system too lean is dangerous, but what about rich???
When I was installing CAI, the PVC tube was loose on CAI.
Didn't think it will go any further. Could this cause the code?

 

To lean will run the engine to hot. Rich wastes gas and leaves carbon deposits.

Go over your CAI install. Call Brenspeed when you can.

 

Check and make sure the pvc tube is on correctly, though I doubt this would cause it to run rich. My suggestion is to re-load the tune and see if the problem persists. Good chance you'll reload and never see that code again.

 

are you using 93 octane fuel?

 

Yes, I'm using 93 tune.
And I checked all connections of my CAI and they are all secured.

I thought it isn't serious, so I cleared the code by Using SCT.
I've driven about 50 miles, and the code won't come back yet.
Once I got SES light, wouldn't it go away, even it reads normal values from sensors?
