Logged this param today because I was trying to
play with the torque management settings (roll off
timing only on the very high end of operation, not
part-throttle). The torque management table I have
to work with is a torque reduction % vs torque. Not
clear on whether this is delivered torque or commanded
torque, as the axis. By the way, the "Desired Torque"
PID returned 377 all the time (even at idle... odd).
The values I got for Delivered ranged from about 20
(idle / low cruise) up to a little over 200 (lb-ft?).
This included some WOT pulls in 2nd, where I would
have expected to see more like 300lb-ft range of
flywheel torque (per the specs of the LS-1 motor).
What are the units of "Delivered Torque" and how
realistic should I expect the value to be vs measured
FWT?
So I'm wondering just how accurate, or not, this
PCM-computed Delivered Torque value is expected
to be. And, if the "Desired Torque" is just a static
value, what would be the PID that corresponds to
the index of the torque reduction vs torque TM table?
What I'm trying to do is just "crop the top" and leave
part-throttle shifts "unmanaged", and have a small
tolerable timing pullback at WOT.
Setting the torque reduction table to hold 300lb-ft
at all values above 300lb-ft (by fitting the reduction
%, increasing) seemed to eliminate TM pretty much
while setting it in the same manner to 200lb-ft made
is come back, a bit lower down than my goal. While
I'm sure I can binary-search my way to satisfaction,
the same can't be said of enlightenment.
