Title: The best strategy for fuel enrichnet - TFSI - Stage 2? Post by: ThomasHH on March 25, 2022, 09:03:26 AM I have been reading about fuel enrichment in MED9.1 for some time but I can't fully understand how to set up the enrichment:
The car is with K04-64 and runs on 1.5bar 3000RPM till 6000RPM. What do you think about this strategy: 1. Set LAMFA about 0.82 from ~2500 to 7000 2. Set KFFDLBTS all 0 (Zero) 3. Set KFLBTS and KFLBTSLBKO mainly 1 and interpolate smoothly to 0.78 after 200Load and 3500RPM 4. Reasonable reduction of the simulated EGT temperature to allow the BTS to remain inactive for as long as possible until further enrichment is really needed (bad fuel or higher IAT). I have concerns about this strategy because I do not fully understand the formula and the full picture of how KFFDLBTS and KFLBTS are related in MED9.1 and which other maps interfere. Тhe strategy above works now for me at WOT, but I don't know what will happen in lower Loads if I have bad fuel along with high IAT and I have turned off the KFFDLBTS and KFLBTS set mainly to 1 in lower Loads. |
