No, its the CAI... the new s197s need to be retuned after every stupid mod... Thats what happens when the computer has complete control over your car.

 

Got a response from Nick at American Muscle and he said it sounds like I uploaded a pre programed tune that comes with the X3 and not the custom tune they put on the X3. I put the stock tune back on the car and then uploaded the custom tune at lunch. I will let you know what happens when I drive home tonight.

 

this is the dumbest thing in the world, you cant add small mods to the car without needing a tune! how stupid is that!

somebody getting some kind of kick back at ford for this one!

 

I must have picked the wrong tune to upload .

Drove it for about an hour after I uploaded the right tune, took it on the FL turnpike for about 25 miles doing 85 and no CEL

 

If the MAF was contaminated during installation, can it be cleaned and how?

 

A towel? lol

 

HAHAHA

 

 

They sell MAF cleaner @ autozone

Carb cleaner works too

 

I think by contaminated he means that he actually touched the wire. I could be wrong but wouldn't that mean that its damaged and cleaner isn't going to do anything? I could be wrong but you can't miss it in just about every set of directions saying DON'T touch the wire and I don't really think they would stress it that much if you could just buy cleaner at autozone haha. As I said though I could be wrong so I'm sure someone will correct me

 

just clean it... why buy a new one when you may not need one?

 

I started looking at information on MAF's after Dave mentioned contamination. Apparently the new cold air intake filters have a light oil applied to them to assist in trapping air particles, makes sense. What happens is that when you first start up the car after installing the new air intake you blow any loose crap off of the air filter and it ends up on the MAF sensor and the CEL comes on.

I was told to disconnect the battery, carefully take the MAF off and clean it MAF cleaner. I was told not to use anything else because the filament in the sensor is too delicate for harsh solvents. Flood the sensor with the cleaner, no such thing as flushing it with too much cleaner. Just make sure to never touch the freak'n wires. let it dry, flush the connector, reattach the battery, reinstall the MAF and fire it up. Take it for a slow cruz to allow the computer to relearn all of the settings and then drive it like you stole it.

The check engine light is gone and it only cost me $7.00! Thanks Dave for the lead!

 

glad your back cruising around

 

awesome... Its nice when its something silly like that... cheap easy fixes ftmfw

 

You would be surprised at how accurate the canned tunes are and can generally be gotten totally specific to an intake. I have an Airade and Diablosport tuner taht came with an "Airaid 93 octane firm shift tune".

may car is an auto. dynoed when it was dead stock, 256 RWHP, after the Intake and the Tune, 290.4 RWHP. Marty what ever tuner you buy, there's a 99.9999% chance that they will have a BBK intake specific tune. You will have to down load the tune from the DiabloSport web site. get a serial cable and download those tunes to your Diablo tuner (you will either need a laptop, so you can use the "power" from the Diagnostic Port under the drivers side dash
or get a 10-12 volt adapter from radio shack to power up the Diablo tuner.

I have a lap top so I plug the tuner into the Diagnostic Port (without the ignition switch on) and then did the download, you have to be sure the baud rate is correctly set on you pc and the tuner. All of the instruction come with the tuner. If I can do it, you can DAMN sure do it.

Good luck

 

Its ford's attempt to provide a lower emission and more fuel efficient car. If something is out of parameter it trips the computer. When you provide more oxygen, as with a CAI, you change the A/F ratio thus altering fuel consumption beyond what is considered efficient. As a matter of fact is a superior system to that of any other mustang of previous years. And in terms of providing improved cars this fits the bill. Now if only car manufacturers could figure a way to have electric cams work reliably then efficiency would sky rocket. Cams are the single biggest area of frictional loss in an engine, I believe its somewhere around 20% of the total loss.
