Hi guys,
Been having some problems tuning a 14 f150 6r80. I am trying to keep the DFCO engaged while under deceleration because i like the "manual" feel that it gives under decel. Im having problems when the revs get down below about 1K RPM where it will command more torque and kick the fuel back on before downshifting then DFCO when it revs up a bit and the revs bounce up and down until it downshifts. I've found that I cant get my shift points high enough to keep drive-ability around town and have the truck downshift before the revs drop too low.
I'm wanting to keep the TCC locked on deceleration in 5th and 4th gear, like it does in 6th to keep the revs up and DFCO engaged. I've tried lowering the TCC lockup to zero, but no matter what, it unlocks when i let off the gas in the lower gears. If someone could point me in the right direction to keep it locked up I would appreciate it. If it has to do with the TCC release > TPS tip out low/high, etc. how do these work and how is the delta torque at -4000?
