Title: How to adjust fuel trims closest to 0 Post by: professor on March 22, 2012, 04:27:22 PM Using those values:
TVUB: Code: V: 7.9565 - 9.9988 - 11.9710 - 14.0105 -15.9858 KRKTE: Code: 0.04706 After few adjustments on TVUB Code: V: 7.9565 - 9.9988 - 11.9710 - 14.0105 -15.9858 in parallel to KRKTE Code: 0.05150 i managed to adjust idle fuel trims to +0.8% (reading of block 32 Bank 1 after driving for 40km). Also by doing those adjustments fuel trims in partial load where dropped from 7.6% to 5.5% by adjusting same maps. How can i make partial fuel trims (high rev trims) richer in order to drop closest to 0? I have siemens deka 630cc injectors. I use for 3bar fpr the above values atm. Would be a good way to higher TVUB on high voltage ms values by a small percentage? Meaning: Code: V: 7.9565 - 9.9988 - 11.9710 - 14.0105 -15.9858 Or is there a better way?

If you have a non-stock MAF/intake setup, adjust KFKHFM Title: Re: How to adjust fuel trims closest to 0 Post by: professor on March 22, 2012, 04:50:41 PM KFKHFM then.
Adding 4% to above 5000rpm && 150% did help and partial trims now are at 2.8%. I ll do some km more before final adjustments. Thanks for the tip nyet (http://nefariousmotorsports.com/forum/index.php?action=profile;u=507). |
