I've been messing around with some different target AF in Crome and wanted some opinions.

D16Z6 - stock
Intake and exhaust
eg hatch
p28 w/ crome dealer

The first pic is what I have been running but I was thinking of switching to the second table with 14.7 up to column 5 and then adding fuel.

I was also wanting to know how do we determine what the difference should be in target AF ratio between Columns. Is there an equation?

Any help would be appreciated.

 

For sure, the first picture looks better. Running richer in columns 7-8 are worthless, indeed, you can lean it a bit on cruise (2000-5000 RPM from columns 3-7), numbers near 15/15.2 are acceptable.

For the last two columns, just enrich them a bit, you will find best performance near 13.3/12.9.

 

yeah it does seem to run much better with the first map. I haven't gotten it to log in column 9 or 10 yet. It usually won't log anything above 5000 RPM either which is a bit annoying.

 

This a stock d16z6. The AF ratio's in my data logs are pretty much spot on but when I look at the 2d graphs they are not smooth at all.

How do I smooth out the maps with out throwing off my AF ratio?
