2020 fk8 AFR and AC issue
Posted: Mon Sep 30, 2024 11:33 pm
Can someone analyze this and explain what's happening? I have XDI 2000cc injectors, RV6 660 turbo, XDI pump, and DW in-tank fuel pump, FBO. Every time I turn the AC on, the AFR and S trim fluctuate wildly. At WOT, the car performs well and feels very strong. However, when cruising and idling with the AC on, strange issues occur. Please help, as my tuner and I have been troubleshooting for about a month with no resolution.
