FITECH EFI TUNING tips, info sharing, ideas, settings, etc...

I ll start!! Installed last August.

ENGINE SIZE: 318 30 over
FITECH SETUP USED:Go 4 Power adder, FCC for fuel supply.
ENGINE VACUUM: 15 inches at idle
CAM SETTING (1,2,3, or 4) AND YOUR CAM SPECS: 2 212/218 duraction at 50
IAC COUNTS @ idle and cruise 7 at idle, cruise.. will add later
TIMING CONTROL: Y/N? Yes, with MSD 6AL, using Mopar performance distributor , Mallory style guts. Base 14, Idle 21 degrees, cruise 39, WOT 33.9 degrees
IDLE RPM: 840
TARGET IDLE AFR: 13.55
ANY ADJUSTED PARAMETERS AND WHY?: where to start.... Upped all accel parameters, regular and fast accel, to get rid of lean spikes . DFCO cutout and return moved down to almost 20 and 24 respectively, ( to reduce decel backfiring through the pipes), Loop up and down at 33 each, ( to aid in quick return to idle) FCC low power reduced to 38.6 %( runs much cooler now).

Had issues with my o2 sensor wiring, self inflicted.. set wires up to tight to the firewall, damaging some lines ( seems better now that I got some slack at the throttle body--- we will see ) If o2 sensor wiring affected it will throw code 105 and 134. 105 fault will display until sensor is hot BTW) Replacement sensor Bosch 17014, if you need.
