  1. Hmm, that sounds odd that a CAI will throw a CEL.  Does the car run a  MAF?

    Your comment about running only 10 pounds could be correct.  Can you tell where the gauge is hooked?  Most OEM turbo equiped cars use the actual compressor housing to read boost, verse reading at the intake manifold.  Obviously if its hooked at the compressor, you will see a boost loss from the the compressor to the manifold. 

    If you see black smoke under hard acceloration, you are correct, it may run slightly rich.  Running the cold air intake won't change that though.  The only way you can change that on a EFI/SC car such as yours would be through ECU adjustment.  I wouldn't worry about the slight smoke though. GM tuned the car that way to create a margin of error (on the safe side).

    That motor is a stout bitch though, it may be a little out of your price range, but your could switch to turbo and make some serious power!  GM will help you out too...they set out to take over the sport compact market and they built the motor to do it.

  2. I awoke this morning to see that my Navi/CD player was missing from my Expo.  It was my fault.  Somehow last night I didn't arm  the alarm.  I had gone shopping with wifey, naturally I carried all the bags in, I just didn't hit the button I guess.

    Here's what kills me.  The thief was so very careful to just unplug the harness from the back, and even tucked the wired back into the dash.  He didn't bother taking the Navi Antenna (dummy). He didn't take my work cell, or the blue-tooth unit.  He didn't take any CD's or my check book.  My rear glass was not completely shut (which killed the battery) so I know he saw the three amps and two 10W7's.  I saw a very small screwdriver-like impression where he tried to take a sub, but after realizing he didn't know how to get to the screws, he didn't even poke a hole in the sub in frustration.

    I guess overall I'm happy that he didn't destroy my truck/equipment.  He was  a thief with a little bit of consious.?.?.?

  3. It's quite confusing, but you'll catch on to it.

    x2...People make it sound like it's simple to work with...Most noobs will never figure it out.

    Don't let my "noob" status on a forum misdirect you...I was building speaker boxes based on the math I did with Thiele/small measurements on a notepad witha pencil when I was 13 (15 years ago).

  4. Yes, again this is controlled by the ECU.  The three upgrades I mentioned are mechanical changes.  Shift points, VTEC engangement is electrical.

    In order for VTEC to engage, you need the following to happen;

    1)Oil pressure at the solonoid must be roughly 75psi (this means you have to have adquate oil level)

    2)Water tempeture must be at usual driving temp.

    3)65-75% throttle position (full throttle)

    When all these conditions exist, the VTEC solonoid opens pushing oil into little pins inside the rockers.  This locks the rockers together allowing the middle lobe on the cam (VTEC LOBE) to lift the valves.  If you ever look at a Honda VTEC camshaft, you will see three lobes.  One big one in the middle (VTEC lobe), and two smaller, offset lobes to either side.

    The two smaller lobes are offset from one another so that they open the intake valves at slightly different times.  This allows for "swirl" to take place inside the cylinder.  This swirl helps flame propagation from the spark plug to create a very efficient burn inside each cylinder.  ***This is how honda's make great power in such a small displacement motor/ with great fuel economy.

    Here's a fun fact for you!

    The Honda Civic Type R (only offered in Japan) was a 1.6 liter motor that made 185hp.  It is still recognized as one of the most efficient motors ever to be placed in a OEM/manufactured vehicle.

    If Ford could duplicate this technology in a mustang,,, Every 5.0 you see on the road would make roughly 

    581 hp in stock trim.

    That's 116 hp/per liter!!
