Your post looks correct, Done. Took me a while to understand it all but after Eric and pilot posted, it made a lot more sense. Looks like me and your are on the same boat.

I am fixing my values in a bit, got some logging to do. I am going to make a MAF scaling for dummies thread after I am done.

Thanks again for the help everyone.

 

OK. I am going to need some serious help here.

I went to go log S/LTFT at idle and cruise. As I was coming back the car idles like complete crap, feels like I popped an IC pipe off but I know I didn't. All the while logging. Car died and wouldnt start for a good 5 minutes. Pull battery, let it sit, comes back on.

Get home to check my logs and it's crazy. My airflow numbers between 800-1000 RPM are freaking in the high 100s. Here are my two logs. First one is cruising, very little to no boost. Second one is coming home from store bogging all the way home pissing me off.

I am going to fully evaluate my S/LTFT but WTF is going on?

 

You sure nothing happened mechanically with the car during that second log? It looks like all of a sudden it goes super lean. The STFT maxes out at +25 and the O2 sensor still sits near 0.

 

Yup, nothing should have happened mechanically because after it stalled out and wouldnt start, I reset the ECU and everything was back to normal the way it drives. My only question is, I did remove the stock BCS the other day... Would that cause my car to drive the way it does? I drove it Monday without ANY issues. I dont know if I should even attempt to scale my MAF. I am going to get my stock BCS tomorrow and plug it back in and see what happens.

Do you happen to have AIM or some type of instant messaging program?

Reading around... It looks like the ECU doesnt like the stock BCS removed. Guess I will go get it now and plug it back in, play again tomorrow.

Stock BCS plugged back in. Also saw that I might have a freaking boost leak... More details tomorrow.
