Quick question. My engine: turbo'd 5.3 . Tune is 3bar Speed density and is spot on regarding VE, starting, Full throttle, etc... BUT.... as the engine fully warms up, when I'm on the freeway and have the cruise control set to 75mph (for example) the wide band will begin to stay at 15.4 -15.6. Now when I first get on the freeway and the engine is not quite heat saturated, it'll be at 14.6 AFR. Its after the temps go from the middle of the first quarter mark to closer to the quarter mark (which is as hot as she ever gets), the fuel appears to lean out. What table in HPTuners is this that moderates fuel based on coolant temp? I'm still using HPTuners Pro version 3.6.26.
Thanks,
Dave
