Title: Part throttle trims and WOTZ fueling issues Post by: Rac_337 on October 08, 2012, 05:06:53 AM Hello,
Im trying to diagnose some issues with a friends 2000 b5 s4 Tial 770R build. first issue is his part throttle fuel trims always read 0. this is strange because his idle fuel trim is reading -.78%. Should there be a reading in the 2nd and 4th cell of block 32? second issue is his WOT fueling and enrichment. The car will dip rich, yet once loads stop increasing it will lean out (14:1 or so). MAF is scaled properly and is 95mm. Any hints are appreciated. Cheers |
