Well I just got a MAFT and wanted to see what kind of settings I should have. I keep hearing set the Lterms to 0 and my o2's at .900 or something of that nature. Anyone know what I need to monitor and at what they should be at, currently the car is running very rich at idle but seems to lean out on the top end.

Thanks.

Do you have ATAP??? Run atap during normal driving and build file to export to excel. You want to check for LTRIM(B1) and LTRIM(B2). Adjust your base on maft to get as close to zero as possible. Then run atap on some wot runs. This time check your 02B1S1 and 02B2S1, also check engine speed, timing, and KR. IMO ideal is somewhere from .880 to .900 with zero kr. This is a repeated test and run so expect to spend some time on it to get it right. Hope this helps.

In addition to what SSleeper said; You will want to check the LTrims only in fuel cells 1-19 while cruising. Check the O2's in fuel cell 22 and while TPS is 100%.
Rock on!

Thanks Guys.

 

Read this, download his files, and use Atap for DOS (it's what his "Config" file will set up):
