ECU override...

I always here of the ECU re-learning back to factory A/F ratios and specs after a certain amount of time. I also heard that if you get an A/F controller like the SAFC II that eventually the adjusted A/F numbers will be superceded by ...once again the ECU. If this holds true then how doesn't the SRT piggyback ECU A/F adjustments get overridden by the stock ECU??? Is this a more permanent fixing of A/F ratios than what an SAFC II can provide? Thanks for the advise...

If you tune within an "allowable" range then it will be ok. A mild/slight tune is ok and the ecu won't fight back. It's when you start dumping a ton of fuel in when you are boosted that the ECU will throw a fit.

So, which in your opinion could/would yield greater results...SRT intake w/ecu or any other intake with a tuned SAFC II?

SAFC, because it can be adjusted to what ever other mods you are running. SRT comes prertuned, so you are stuck with one setting of A/F ratio.

It's also the VVT-i that is doing this, and adjusting the fuel ratio according to how you drive over a couple hundred miles.

Oddly enough...my SRT intake and ECU causes a CEL every now and then. I reset the computer twice...then just left it alone. It goes back off eventually after a few days and resumes normal operation. BUT...I do have 84,000 on original plugs and such...so I am sure a fresh plug install would help there. Hasnt come back on for a while now. Usually comes on when I drive the car as opposed to my lady, who drives it daily. I drive a supercharged 05 Acura TL instead cause I couldnt get her out of the damn Lexus when it came time for us to get another car and her relinquish it to me as originally planned.
