Thread: AFR and Timing Tuning (02 Regal GS 223k!!!)

General "afr at wot" tuning will be done in your PE tables.. pick your poison there it really doesnt matter. This will change your requested afr (which I noticed you are not scanning, why?)



LQ4 is a nice maf, no reason to ditch it really. Make sure you have the "right" LQ4 table out there and go for it. I cant really gauge from your posts what maf table you are currently using.

What is this requested afr you speak of not in the scan? Is actual not ok when the wb is hooked up? In the table it is displayed as seen. I am trying to un-hack tune the car but there is not an actual lq4 maf file in the pcm as I asked the previous owner. He just modified the stock file to work. It looked like a roller coaster. It is much better looking now. I am not flowing 11500 plus so I really see no need for this lq4 or any gains it would give me. Right?


Also how am I hitting 10500 hz on tis setup? My gtp was on spray/cammed and hitting 10,000hz at times seen here.

But why use NB to tweak the IFR's? I mean if I have the WB hooked up that is the best unless I misunderstood.

Would shrinking my 104s from .054 to .050 net me any possibility to add more timing?
