    Hey guys, I just started to tune my car (b18b-450-t3/t04e).  Now I've been using a basemap called "ls-450's-t25-7lb " and it's been working great for my motor and turbo. My a/f ratios are 14ish and about 11.3 in 5 lbs of boost.  The only problem is when I turn up the boost to 10 lbs it's a bit lean 11.9-12.1.  All I want to do was richen it up a bit.

New her is my question after the changes I made the a/f ratio went up to 13.9-14.6.  No matter what I did I COULD NOT get the a/f ratio down.  I added more fuel and even had the timing down to 6 degrees and still got 13.8 to 14.3 a/f ratio at 10 psi. 

I made the changes on my home PC and I must have changed the chip like twenty times.  Every time I made a change to the basemap the result was the same 14ish a/f ratios.  Please help

Have you disabled the O2 sensor and tried it that way?

[ratcityrex]

Your fine with your afrs at 11.9-12.1 just go back to your basemap

Have you disabled the O2 sensor and tried it that way?

The O2 sensor is disabled!  Plus Its not even wired to my ecu.  The only part that's aftected is where I make my changes, the rest stays the same.  I remember a screan shot of a something called target a/f ratios but can't seam to find it in crome. 

The only reason I wanted lower a/f ratios is becouse it gets up to 120+ in the summer here.

Thanks guys any futher help whould be apreciated.

Timing is more important than fuel with higher air temps. Just pull a degree or two to be safe.

[lilpooh21186]

are you using Crome free or pro crome pro has target afr its the green A type symble

[snarf]

crome free. I really want to be able to tune my own maps more than anything.  Has anyone ever had a similar problem?  Thanks guys

[ratcityrex]

What version of crome are you using?

[snarf]

1.5.0

[turbo4life]

return to your previous setting 11.9 12.1 is perfect reduce the timing a touch.. *higher air temperatur*  knock

[marcj]

so you were at 11.9-12.1 at 10psi, then you added fuel and now it's even leaner? 

[snarf]

Yea, must be something wrong with crome since no one else has had this problem.  I'll try to reinstall it and make my own basemap.  I'll let you guys know when I fix it.
